His familial sensitivity to metals made his body violently reject vaccines, dental work, and orthopedic implants.

Mark is a brilliant person whose health problems have whipped him into spending a decade investigating this subject. This is one of my best interviews, and the Rumble link is HERE.
Mark has much in common with the prescription drug-damaged people on Tim Alexander’s “Legal Death” Facebook site. Tim was propelled into action by his family connection to the San Bernadino killer, who turned violent because of psychiatric drugs. Tim’s fascinating story is HERE.
Mark has had his life ruined by metal exposure. These before and after photographs tell his story:


Mark said, “That droopy face photo was taken around four months after the surgery. The implant had titanium screws and carbon fibre rods. I ended up being allergic to it all.”
To improve his health, Mr. Kennard studied metal toxicity by networking with international experts. Although he is far more affected than other people, he has lessons for us all.
Dr. Schroeder, a podiatrist, became an authority when he saw patients with issues like Mark’s. He faces the orthopedists and tells them that the ways they use implanted metals is careless.
Since few doctors in medicine or dentistry are interested in these issues, you cannot find this material in one place elsewhere.
Horse doctors look in their patients’ mouths first, and if you have any health problems, this is your best first step to solving them. Oral bacteria have been found in the majority of coronary artery blockages and have also been studied inside Alzheimer’s disease brain structures. Mercury dental amalgams are another huge problem. These are still placed into 100 million Americans each year.
If you read my three dental posts (the references are below), you recall that I described four issues:
Infections of root canals, implanted teeth and other dental work. These are almost universal and frequently asymptomatic. The treatment is most often removal without replacement.
Battery or current effects between different metals in the body, such as orthopedic titanium alloys and mercury and aluminum in dental work. This causes toxic metal shedding into the body.
Allergies or special sensitivities to metals, which can be much worse. Mark has this.
Mercury extrusion from dental amalgams happens even in the absence of the above. It is the most toxic non-radioactive metal; half US dentists use it anyway. Allowing these ignorant, careless fools to continue this is an atrocity.
Mr. Kennard says that any surgeon or dentist placing metals inside the human body must be aware of all these problems and test their patients before they operate. None of them do this now, and many do not even inquire about metal allergies. When asked, many people (17 percent for nickel alone) say, for example, “Yes, I get a rash on my wrist where my watch touches,” or “Cheap jewelry and I do not get along.”
Even titanium, generally regarded as biologically inert, has a reported allergy rate between .6 and 2.3 percent. Orthopedic and dental implants manufactured with this are alloyed with other metals, including aluminum, the second most toxic metal after mercury.
Implants for sensitive people are commercially available. These include nitride coating or ceramics.
Mark also tells us how to detox safely and what the pitfalls are. Vitamin C is a wonder for health if you have no metals in your body, but it can speed up metal disintegration and toxicity if you are highly sensitive. Another medical marvel, chelation, must be used cautiously and only by experienced practitioners. EDTA chelation should not be used for mercury.
I have 17 amalgams that are scheduled for removal in August. My dentist drew blood to see if I would have problems with various composite filings. The report says I am reacting to mercury, aluminum, and several other metals. Although there are thousands of dental materials, Mark Kennard and Teresa Franklin (the co-author of Mercury Free) said Saremco composite fillings are the least reactive type because these are supposedly metal-free.
Mark wrote me about my situation:
I’ve looked at that report, and based on it, your dentist will choose the best replacement for your amalgam fillings.
After you get your amalgams removed and remove all other sources of aluminium that you can as well, your biggest issue will be the aluminium in your orthopaedic implants. Because I don’t know the ingredients in your mesh [from my hernia procedures when I was 23], I can’t comment on that but if it has aluminium in it then it will also be a concern.
That report shows you have breached your mercury and aluminium antigen tolerance levels. The report tells you how your blood is reacting right now, and right now your blood is telling you that it is not coping with mercury or aluminium and that they will be causing you symptoms of some kind.
That’s the best way to interpret it. But it should be interpreted in conjunction with reading the following statements. Because the most important thing that needs to be understood is the meaning of hypersensitivity and your biggest risk to your health and life after getting the mercury removed is the aluminium in your orthopaedic implants.
You could decide to replace them with something more biocompatible but the only thing that would help is something which doesn’t release aluminium ions. Something without any aluminium at all and that’s a challenge.
Hypersensitivity isn’t a label for the type of person that has bad reactions to metals because of gene mutations.
EVERYONE implanted with metals will eventually get really symptomatic and die but in people with certain gene mutations it just happens sooner.
We all become hypersensitive to metals from exposure. Every single one of us, because metals are the most difficult toxin for the body to deal with as they are not liquids but solids. That’s the best way to look at it.
Everyone exposed permanently to aluminium will get dementia or Alzheimer’s type symptoms.
Hypersensitivity is a label that means our body isn’t coping with metals RIGHT NOW. So both mercury and aluminium are causing you problems right now.
And this is the most important thing you need to consider when deciding on chelation or detoxification. Your body isn’t coping with aluminium right now. Any process that speeds up the corrosion of your titanium alloy implants will release aluminium into your body too.
Slowing down the release of aluminium ions will buy you more time being healthy and alive on this planet.
Removing the implants and replacing them with something which has zero aluminium will be difficult [custom implants can be made].
If you had implants that had zero aluminium, I’d say go ahead and use products that speed up your detox processes
But because there is aluminium in the titanium [shoulder] implants, my advice is not to unless you plan on replacing all your implants with new ones which contain no aluminium at all.
Because if the implants are being left in, then it’s all about buying time.
Hopefully the worst symptoms you have are caused by the mercury only. They can have similar symptoms.
If they are, then all your health symptoms will vanish. But they won’t be.
Symptoms that the aluminium are causing will not disappear unless you remove everything from your body which has aluminium in it.
Once you have removed the mercury fillings, we need to reassess things.
I have a colleague who is an orthopedic implant surgeon. He and his partners have done thousands of knee and hip implants and have seen only a few problems like Mark’s. In the early phases of my friend’s career, the implants of the day had less biocompatible metals, so the long-term results were less consistent. He says that today’s titanium alloys containing aluminum, titanium, and vanadium have superior strength, biological compatibility, and wear characteristics. He reminded me that hip implants are regarded as the best surgery of the 20th Century. He writes:
Chromium cobalt (CrCo) implants have been used since the 1940s and were (and still are in some places) bonded to the bone using methyl methacrylate acrylic cement. CrCo alloys contain a small amount of nickel and are a source of what is thought to be true implant hypersensitivity reactions, yet they rarely require revisions. I’ve seen maybe two severe allergy cases in my career. Failed implants requiring surgery have many factors in play, so surgeons have difficulty being sure about the causes.
Structurally, implants are durable and resist breakage and surface wear. Loosening at the bone interface after 10-20 years is the most common cause of failure.
Biologically bonding (bone ingrowth technology) is now used for most modern implants to eliminate cement and reduce loosening over time as the “grout” fatigues and breaks down. It does not work well for the glenoid [the cup part of the shoulder joint], and the cement works better. Biological bonding involves texturing surfaces so the implant attaches to bone. Once ingrown, these self-repair by remodeling over time. CrCo is strong and inflexible (resisting breakage) but is affected by the implant material and bone elasticity mismatch. This may lead to atrophy and resorption of adjacent bone, which can produce bone loss, fatigue fractures, and loosening over time.
Commercially pure titanium and aluminum, and V alloys of titanium or Niobium, have similar qualities as bone, so remodeling is more favorable and physiologically compatible. Like aircraft wings, they are fatigue-resistant under repetitive mechanical stress. Unfortunately, pure titanium alone is not as strong, and even its alloys, though stronger, have poor wear characteristics of their bearing surfaces. These must be altered to improve wear. This is done with nitriding, ceramic coating, and other methods. These add to the cost, potentially alter biocompatibility, and likely have other long-term issues.
Metal-on-metal (MOM) hip implants were used between about 2004 to 2012. These were associated with metal ion shedding and debris. For some people, this is directly toxic. This has as much to do with the design of the implants as with the materials used. Interestingly, about 70% of MOM hips are still doing fine and seem to last indefinitely, whereas most conventional metal or ceramic on polyethylene bearings will eventually fail in active patients within 20 years. The most modern polyethylene (treated by cross-linking the polymer chains) is inert and durable, but we only have about 20 years of data for it. This is the most common material used in hip, knee, shoulder and other implants now.
Particulates related to wear, loosening, or implant breakage are generated in implants by polyethylene, cement, or even implant texture fragmentation. This shedding causes tissue reactions for every patient to some degree. It may be direct toxicity from metal ions (chromium, cobalt, and aluminum), foreign body reaction (anything of a certain particle size and amount, including cement and ceramic debris), or allergic (typically nickel).
Distinguishing between occult loosening and infection can be difficult in mild cases.
Infection and bearing surface failure are the most common causes requiring hip and knee revisions. After ten years, two to four percent of patients in primary cases need revision, and twice that many occur in revision cases.
As a practicing surgeon, the usual problem is deciding when to re-operate on previously implanted people who developed pain. If this happens quickly—for example, three to four years after hip replacement—we often have a diagnostic dilemma. We have no definitive tests to guide us. Even if we know an allergy is involved, whether to operate may be unclear. Hip revisions are big surgeries with significant risks, and many people do well in the long-term tolerating low-grade pain with the help of ibuprofen or Tylenol.
We do bloodwork, serum ions, joint aspiration, and imaging, but these are often inconclusive. X-rays might eventually show changes, but this could take six to eighteen mos. The surgeon could be liable for a missed diagnosis but hates to subject the patient to a procedure that may not improve his status.
Vast numbers of implants are placed, so allergic and sensitivity problems are significant and certainly under-appreciated. I doubt if one orthopedist in a thousand understands the problems with electrical currents between metals inside the body. I understand their viewpoint—they manage a spectrum of clinical problems and have trouble sorting out the importance of each one.
Allergy testing before surgery would improve informed consent and is a cheap price to pay for better outcomes.
I have been asked whether I would have had my titanium alloy and chrome shoulder implants done if I knew then what I know now. I am not sure. My pain was tolerable before the procedure, and I have no pain now and am more functional. But I have some doubts about the metals’ impact on my long-term health. If a patient were in this situation and asked me, I would probably tell them, “Minor surgery is surgery someone else is having.”

The garbage you never want inside your body is italicized.

Crest toothpaste’s ingredients: Active Ingredients: Sodium Fluoride (0.15% w/v Fluoride Ion) (0.243 %), [this is a lot of neurotoxin]. Inactive Ingredients: Sorbitol [in diabetic patients or those with extremely high glucose levels, sorbitol may accumulate to toxic levels and leads to complications within these organs. Nausea, gas, diarrhea, stomach cramps or anal irritation], Water, Hydrated Silica [allergic reactions, for example, rash and swelling of the face, upset stomach, hypoglycemia in people with diabetes], Sodium Lauryl Sulfate [may slowly build up in your body over long-term use, but the amounts are small. The highest risk of using products with SLS and SLES is irritation to your eyes, skin, mouth, and lungs], Trisodium Phosphate [kidney damage, soft tissue calcification, and bone calcium removal. Continuous ingestion over a long period is linked to bone density diseases such as osteoporosis], Flavor [unidentified], Cellulose Gum, Sodium Phosphate[irregular heartbeat, vomiting, fainting, seizures, rash, hives, itching, swelling of the eyes, face, lips, tongue, mouth or throat], Carbomer [Blurred vision, eyelid margin crusting, corneal irritation, increased lacrimation; periorbital and conjunctival edema; ocular discomfort, pain, pruritus, and hyperaemia; contact dermatitis], Sodium Saccharin [rat carcinogen, banned 1981- 2000], Titanium Dioxide [!], Blue 1.
Crest is recommended by dentists:
One of the only toothpastes accepted by the ADA in six categories, Crest Pro-Health, does it all. In addition to whitening teeth, it reduces sensitivity, prevents cavities, fights plaque, prevents gingivitis, and combats bad breath. For all-around oral hygiene, this toothpaste is a winner.
I have a Titanium plate with four screws in my cervical spine. It was from a 2001 episode where a Chiropractor ruptured a disk in my neck. The Neurosurgeon afterward told me heu2019d never before seen a disc broken into three large chunks.
So all in all, Iu2019m glad to be alive today and have my wits about me.
Mark is unusually sensitive
Doctors continue to be misinformed that titanium is completely safe to implant in the body. The safety of titanium is under scrutiny…
https://www.sciencedaily.com/releases/2011/07/110725101257.htm
If you have no serious health issues that developed following implant, you currently have no issue, but titanium implants are now known to erode over time, so beware
After considering this I wonder if some people arenu2019t allergic to the metal in braces? Why do some teens get such horrible acne and others donu2019t. The girl who waited on me yesterday had terrible skin AND braces!!! Both my nieces had severe acne AND braces.
yes you deserve a draft post. Chew on this:

Can you please advise as to what type of toothpaste is a good choice?
I revised this post https://robertyoho.substack.com/p/1ff80bd0-9448-490a-a2d6-374887dab536 about this. Tom’s is good but read to see why
Iu2019d like to read this post but the link only leads to your general home page/list of all posts, not to any specific article. Could you provide the date of this post so I can locate it? Thanks!
Also, I thought I understood silica water to be beneficial in helping remove aluminum from the body but now Iu2019m questioning that after reading todayu2019s post? We use Xyli-white and love it (Tomu2019s wasnu2019t our favorite) but checking the ingredients now show that it does contain hydrated silica. Iu2019d appreciate any thoughts you have – thank you!
Silica gets rid of aluminum Try link again https://robertyoho.substack.com/p/1ff80bd0-9448-490a-a2d6-374887dab536#details
It worked this time – thank you!
We know Chromium in hip implants causes issues.
What is the skinny on aluminum? Seems my Synthroid is produced by AbbieVie, a spin-off of Abbot, it specifically mentions the 1.50 mcg. Dye is Blie Lake for both 1.37 mcg. The only difference is 1.3 is a deeper blue. Did they change a filler? I don’t react like your guest, but have a full typed sheet of reactions of various types.
I have to stick with the same soaps, shampoos, laundry, etc. Even the scent is an issue. Most hated aisle in grocery stores.
have some draft posts about aluminum:

It all depends on your own biology. We become sensitive to metals from exposure to them with the severity of reaction based on our own biology. I also have to be careful with soaps and other personal care products due to the titanium dioxide. I have become hypersensitive to both titanium and aluminium.
Itu2019s becoming sensitised that is the important bit.
If we can keep metals out of our body(including the aluminium in vaccines we donu2019t become hypersensitised to them. When we do become hypersensitised we also become sensitive to all other chemicals and once our bodies have too much metals to cope with thatu2019s when disease occurs. Metals are the trigger of most disease. Removing metals from our body will always bring health improvements. Even arthritis and endometriosis are triggered by metals. We can cope with a certain amount but itu2019s once we are exposed to more than our immune system can rid itself on a daily basis.
Avoid metals, prevent disease.
As soon as we put any foreign object into our mouths or body our immune system adjusts to cope. Removing the foreign object and the body returns to functioning like it should.
Toothpaste is one of the hardest things for me due to sensitivity
Because the metals triggered mast cell degranulation in me.
Itu2019s a product that you just have to buy the best one you can get.
You can brush teeth with organic baking soda but even this requires care in the hypersensitive as it can mess with your body chemistry.
Makes sense. I can eat any food from cans, except for Fruit. It leaves a nasty acidic taste. I need that in glass jars. https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse1.mm.bing.net%2Fth%3Fid%3DOIP.Qp58N9BPwUXvZTxP7lFpOwHaHa%26pid%3DApi&f=1&ipt=4565b0d96c75641b7d77263a3fa74c7c2b0c03a833603591d9648003d823897f&ipo=images
Tomatoes, which are very acidic, leach a lot of aluminum from cans. I buy my tomato products in cardboard boxes. I very rarely eat ANYTHING from a can.

Any thoughts about titanium used to support the rib cage after a recent open heart surgery?
Titanium hypersensitivity is the rarest but scientists say humans are becoming more and more sensitised to it because thereu2019s also titanium dioxide nanoparticles in the air we breath.
I reacted to titanium in the first week after implantation with both my 2095 and 2019 implants but thatu2019s because people with my gene mutation always do react quickly.
Everyone becomes hypersensitised eventually but some take decades for that to occur
All weight bearing titanium implants are actually an alloy of titanium. Called Ti6AL4V and has 6% aluminium and 4% vanadium
Typo 2005 not 2095
Any truth or merit to using greens in diet to detox these metals?
Vegetables are great at detoxifying. Onions and cabbage are the best.
But there are also metals in vegetables and itu2019s been discovered women hypersensitive to nickel can develop endometriosis solely from the metals in their diet.
A nickel free diet is a good idea. There are apps that help people choose what foods are nickel free
Mark & Robert,I appreciate your comments and thoughts.
Mark is the knowledgeable one
https://www.sciencedaily.com/releases/2011/07/110725101257.htm
Titanium problems are rare
That is now debatable…
https://www.sciencedaily.com/releases/2011/07/110725101257.htm
Be sure to watch Roberts next few posts as the focus on this is going to be the best and most important health advice anyone can have.
Because metals are the trigger for most disease. Removing composite dental fillings cured my cardiac issues and my blood pressure and pulse returned to normal recently
Another thing of note is that in Europe titanium dioxide has recently been reclassified as unfit for human consumption. But they didnu2019t mention anything about all the people with titanium dioxide in their dental work. This is a big problem
I can attest that my experience with metals was very similar to Mark’s. However, it took me over 2 years to realize the cause of my health issues. If you are experiencing ill health and your doctors cannot determine why, and you have metal in your body, look into the possibility that the metal may be the cause, and save yourself the suffering that I have, and continue to, go through
Terri Franklin (see this post https://robertyoho.substack.com/p/1e28a470-5a23-42a8-8873-ce18163b50da) emailed me: Bob, the reason metals are so reactive is not because they are liquids not solids as it states here. It is because they have a positive charge and are highly attracted to negatively charged ions. They also have different levels of positive charge such that they pull ions off of each other. Scott can explain this better. For example titaniumu2019s charge is different from aluminum and so there is a net ionic pull from one metal to the other u2013 leading to corrosion.
I’m really interested in your upcoming amalgam removal experience. I’m going to do it I think. At 57, I still have a bunch of them. I’ve already had a good dentist replace two damaged amalgams with ceramic and they look great.
They have got to go. I will write about the dentist etc. I’m getting 17 out and replaced in Tijuana for $6800! Ck out this upcoming post. https://robertyoho.substack.com/p/186b3a63-b52d-48ef-b405-0f200b4270d8
Good article thanks. I have Titanium/ceramic hip. Magnesium gluconate has been shown to chelate some heavy metals including aluminium.

Mark mentions he and members of his family have certain gene polymorphisms (SNPs) that have exacerbated sensitivity to metals. Some folks may be familiar with interest in MTHFR and related SNPs (Dr Ben Lynch, Dr Amy Yasko etc) from their own healrh struggles and subsequent genetic testing. Which polymorphisms are implicated in metal allergies/sensitivities?
I have readers who will comment but I have not studied this
Yes people with the mthfr gene mutation variants always appear to have the worst sensitivity reactions to metals as they mean our bodies donu2019t process metals as efficiently as other people. I still had high levels of mercury in my blood 8 years after they were removed. But I know others who donu2019t have the mthfr gene mutation with a mouthful of amalgam fillings who had no mercury in their blood. Their biology was simply more efficient at processing metal toxins
Here is a draft post on mg
https://robertyoho.substack.com/p/cdb0a3cd-8797-4f0a-b8ea-79c9ced73854
I was diagnosed with osteonecrosis (AVN) in my left shoulder joint last year, and later diagnosed with it in both hip joints. Thereu2019s no cure. The only remedy is total joint replacement. The ends of the humerus and femur bones (where they meet the joint) die from lack of blood flow and eventually the bone turns to mush and collapses.
Finding an orthopedic surgeon who has knowledge and experience in treating this disease was a major challenge.
The next challenge was finding the surgeon with knowledge about metal allergies. Iu2019ve always been allergic to nickel. Shoulder and hip implants commonly contain nickel (and other metals.)
Apparently, finding a company that makes nickel or metal-free hip implants is a lot easier than finding one that makes nickel or metal-free shoulder implants. Even if the implants themselves are metal-free, it seems that they might still contain other types of metal like titanium in their components or hardware.
I went to six orthopedic surgeons before finding one that performs shoulder replacement surgery, and although heu2019s not personally experienced with treating AVN, heu2019s very open to learning all he can.
Unfortunately, metal allergies are not even a consideration for most surgeons. Most surgeons I talked with believe that because the metal will be inside the body as opposed to being against the skin (Iu2019m allergic to jewelry made with nickel. My skin swells and I get a rash wherever it was in contact with nickel,) there canu2019t be an allergic reaction. That doesnu2019t make sense to me, but Iu2019m not a doctor!
Thankfully, my doctor is open minded and was willing to read all the reports and articles I found on metal allergies and implants.
Iu2019ve been postponing my surgeries because I donu2019t want any metal at all used for the implants. The thought of having implants scares me. For the time being I can handle the pain. Once collapse occurs I wonu2019t have a choice but to have my joints replaced. Hopefully, by then there will be 100% metal-free implants available.
see above. Also you might consider your hormonal status. Read Hormone Secrets for background and find a bioidentical hormone provider.
The Goddess will help.
Get a MELISA test to establish what you have first.
There are ceramic or coated implants.
Custom implants are available too, and if you have well-documented problems, your insurance may pay.
Hey I’m doing my heavy metals pee collection right now (before I start having my amalgams removed). Thanks for inspiring me to not take all the junk in my mouth for granted any more. P.S. I am working with a CHIRP on my blood and heavy metals tests.
