Fact-checking stem cell supplements in 2024

Today’s post is a review and fact check of stem cell supplements.

What I found now in 2024 on stem cell pills and related supplements is concerning. As a stem cell biologist, I see risks here not only of wasting one’s money (no positive effect), but also of doing some harm. In certain cases, stem cell supplements are actually unapproved drugs based on their claims. They would definitely have risks.

Let’s go through the potential risks and benefits here as we discuss the science.

Quick Article Summary and Claim Review. Stem cell supplements claim that they will improve your health via impacting your stem cells. My research indicates there are no strong data to support such claims. Stem cell supplements also could have risks. They are very expensive too. As a stem cell biologist I recommend against taking stem cell supplements, but consult your physician.

Note that “supplements” here refer to things people can ingest, not “supplements” that us scientists add to the media we use to grow stem cells.

Stem cell supplement capsules, vitamins, more

For context, I’m fairly skeptical of supplements in general. The main reason to take them is if one has a documented deficiency in something. Maybe like iron or maybe (maybe not) Vitamin D, or if you are vegan maybe you should take B12.

As a 10+ year prostate cancer survivor the only supplement I take is Vitamin D. However, I’m having my doubts even about that. Ten years ago it made sense to me theoretically that a hormone like Vitamin D might help prevent cancer recurrence. This idea was based on in vitro results growing cancer cells in a dish. However, the literature hasn’t been very encouraging on any benefit in actual people.

I more recently fact-checked the supposed brain supplement Prevagen. There are reasons to be concerned about their advertising claims and also about potential risks.

Stem cell supplements claims

So what about supplements claiming some link to stem cells?

There’s not much foundation for them and they cost a bundle.

The main claim of these supplements is that they’ll make you have more stem cells. Sometimes they claim to make you have happier stem cells. Others claim the pills aid in stem cells differentiating into the desired cell type. We are seeing more stem cell supplements claim anti-aging effects in the last few years.

A big surprise for me was that searching Clinicaltrials.gov finds many studies on stem cells and supplements. But there is little data. One study that did have data was focused on a supplement called NutraStem. It tested effects on CD133+ or CD34+ cells as compared to a placebo. It didn’t seem to work.

There is no evidence of supposed stem cell eye supplements benefiting eyes or vision either (more below).

Supplement ads & products

A Google search for “Stem cell supplements” yields an array of results and ads.

While Google has rightly (and generally very effectively) banned stem cell clinic ads, it still feels like anything goes with stem cell supplement ads. You can see a screenshot above for some results. An Amazon search yields tons of overlapping and sometimes wild results too. Some price tags approach a thousand dollars a pop.

Take a look at a “grassfed bone marrow”. I’m imagining a test tube of living bone marrow with someone trying to feed it grass. This supplement claims to have something to do with stem cells:

“Contains all the nutrients, specialized cells (including stem cells and base cells), collagen, growth factors, fat soluble activators and substances that the body uses to build, repair, and maintain all tissues”

I doubt there are living stem cells in there. And, what are “base cells”? Basal cells?

What about Visiclear, Visifree & Visishield?

I’ve been hearing more about vision-related supplements. The most popular ones are called Visiclear, Visifree, and Visishield.

These supplements contain vitamins, antioxidants and other factors. Various claims on the web suggest that these products may help vision by either keeping stem cells healthy or restoring stem cell health.

I’m highly skeptical.

We stem cell researchers do sometimes add vitamins or antioxidants to our cultures of stem cells in the lab. Yet it’s not clear that antioxidants that people eat or take as supplements would have benefits to endogenous stem cells, including in the eye.

A quick search on Amazon found that these products are also very expensive. No surprise. There are quite a few unhappy customers who left reviews there as well.

As a stem cell researcher, I wouldn’t recommend Visiclear, Visifree, or Visishield.

Stem-Kine review

Something called Stem-Kine from Neil Riordan, who runs a stem cell clinic firm in Panama, often pops up on the web. A decade ago he published a paper on Stem-Kine. It claimed a link to mobilizing stem cells, but I’m not convinced at all.

Physicians in the hospital can reproducibly mobilize stem cells in donors or patients. However, this is done using powerful, proven drugs. This has been the subject of tons of published research such as related to preparing stem cell transplants after chemo in cancer patients. (By the way, you might find this guest post on a family’s experience with stem cell donation to be an interesting read.)

These stem cell pill supplements are super expensive too. How much does Stem-Kine cost? For a case of 60 x 700mg capsules on Amazon you’ll pay about $70. It seems ridiculous to me.

But could it work?

It’s hard to say without more data, but I doubt it and anything like this has risks too.

Further, it’s not clear that mobilizing bone marrow stem cells in a healthy patient on a regular basis is a wise thing to do.

Check out the comments from Wise Young in the comments section for another view.

Regenexx supplements

The Regenexx brand has a whole supplement product line now including Regenexx Complex. One supplement, called “Advanced Stem Cell Support Formula” costs about one hundred bucks for 32 fluid ounces which is about $400 a gallon.

The description says it’s a “proprietary blend of vitamins, herbs, and supplements that may help support healthy stem cell function and cartilage production.”

The Amazon page for this or a very similar product lists these ingredients: “Vitamin C 1000mg, Vitamin D 2000IU Proprietary Blend 3455 mg of Glucosamine Sulfate and HCl, Chondroitin Sulfate, Curcumin, L-Carnosine, Resleratrol (resVida), Bitter Melon, BioPerine Does not contain wheat, gluten, sugar, soy or dairy. Contains ingredients derived from shellfish and corn.”

Is there any published clinical data to back up this expensive supplement’s use in people? Not that I could see. I don’t see a good rationale for Regenexx Complex either.

Note that Advanced Stem Cell Support Formula comes in citrus or strawberry banana flavor. A good-sized Jamba juice with fresh strawberries and bananas, and a boost of some vitamins in it costs about $6 or $7. I haven’t had one of those in years, but they sound good even if rather full of sugar.

Big picture take-home: do stem cell pills or supplements work?

Overall, in my view “stem cell” supplements are not worth the money, probably won’t do anything terribly exciting in a positive way, and could have risks. You can watch a Q&A YouTube video I did below in which one question and answer was related to stem cell supplements.

Note that I actually had an old post (Top 5 possible natural stem cell boosts) on possible simple ways to possibly boost stem cell numbers in a more general sense, but admittedly even these ideas are speculative and do not involve supplements or paying money. For example, try to sleep a healthy amount and especially exercise more in certain ways.

At this point in my view exercise seems like maybe the only possibly reliable and safe way to impact certain kinds of stem cell numbers in your body.

We’ll see in coming years or decades if any specific supplement can convincingly do something useful that is stem cell-related based on more research. It’s also important to consider that anything that boosts stem cell numbers could also pose the risk of unwanted consequences like abnormal cell or tissue growth.

The Cerule Stemenhance supplement has five papers mentioned in PubMed on it, but I’m not convinced by the data there that there are clear, lasting benefits to users. At least one of the papers suggests in one system the supplement did not promote tumor growth.

Will there ever be a stem cell pill that one can take to somehow improve your stem cells in numbers or function in a safe way that positively impacts specific aspects of your health? We’ll see but right now there is nothing like that.

  1. What experience do you have with the following label —

    • The stem Cell Solution —

    • Manufactured for —
    Health, Energy, Longevity, LLC

  2. Thanks for your review! I found this by looking for HealthyLooking.com reviews. Even though you didn’t specifically mention them I am skeptical about sending them any money. The site is recommended by George Noory from Coast to Coast but, oh well.

  3. I have a broken kneecap which has resulted with my knee bone on bone. Nothing helps and I am in much pain. What stem cell activators do you recommend for my knee. Thank you

    1. What are your thoughts of x39? A patch that activates stemcells or alleges to. Lifewave is the provider/supplier. Interestingly they’re a mlm. Is this the new vitamin wave where everyone sells their vitamins? Or does X39 patch which is alleged to harness light to elevate a copper peptide to activate stem cells.

    I’ve just started to read comments and came across yours. Can I please ask what stem cell supplements you were taking. I’m in the UK.

  5. Why buy a supplement that encourages stem-cell activity which costs more than the raw ingredients if bought individually in powdered form? They’re available in bulk at good, competitive prices online.

  6. I happened on this page as I was doing research on my age related macro degeneration. I am interested in the “stem cell:”research project re-same that is currently in level three trials.

    Your readers buy products for which there is no scientific evidence at all that they work or are safe to use. They simply choose to believe.

    As a Canadian reading your blog I think I finally understand the Trump voter. They are your readers!!!!! They clearly have no idea of what is involved in scientific research or what it means to establish something as “true” or “false”.
    The majority of what your President Trump says is simply not true and easily proven NOT to be true.. But you Trumper’s on this blog so want it to be true that you simply choose to believe .The same way you’d believe in “stem cell” supplements or “snake oil.
    Have any of you figured out where and by whom the 8 million votes were stolen for Biden. How were the volunteers in polling stations across your nation both republican and democrat hoodwinked into certifying the vote. How did the democrats get all those officials to participate in a massive fraud and still no one can find any proof of how they pulled it off. But you choose to believe they did!!!!!
    Instead of blogging about “stem cell” supplements why do you not look up the research that proves their efficacy–oh sorry there isn’t any!!!!!

    1. My gosh, lady!!! You managed to turn a totally non political post into something political!!! Geesh!
      Regarding the actual article: Good job on the research! Very informative! Thank you!

  7. Am 55+ female. Thinking of using stem cell activator for diabetes (body redesigning). Saw it on Christian programming. However, have beem using deer antler spray on both knees & elbows. No more pain or twinges. If i feel any pain, i just spray it on a few times a week and will go pain free for montgs. Also use it on sprains for my husband & grown children. Works great but u are supposed to spray in your mouth. Just got 2 new bottles (less than $10 each). Will try that befotlre i spend $50 on stem cell activators.God only knows- maybe that will help.

    1. When you try something like stem cells it is a hail marry. I was a 20oz steak away from dialysis. So why not try it. A year later and still not on dialysis. Did the stem cell activators help? I don’t know but they didn’t hurt. Now it’s like my lucky shirt. I’ll wear it until I lose.

  8. As a coauthor on both of Neil Riordan’s papers on Stem-Kine, I would love for you to say why “you are not convinced at all” ??

    There was upregulation of circulating hematopoietic stem cells and endothelial progenitor cells in the blood after volunteers took it. What is your issue with the data?

    1. Well, for example, in the 2010 JTM paper there was no blinding, no randomization, no placebo control.
      I also wonder how was the “Day 0” sample stored? Could some of the purported differences simply be because this control sample was sitting around in the fridge and was older than the others? Or if it was analyzed right after being drawn, then that means the other later day samples were not analyzed at the same time as the control, which could be problematic. The list goes on…

    If who ever supposedly engineered the Covid virus had set it up to only affect politicians then he would get the Nobel Peace Prize. But, a lot of innocent people are paying the price. What right would anyone have to do that? Bill Gates helps lots of people and has many charities. He made his money because he is brilliant and works hard. We all had the chance and let it slip through our fingers. He didn’t. I commend Mr. Gates for everything he has done and none of you should believe any of this baloney for one minute. After all of the dirty things Trump has done, why is he still in office? He is the problem and the cause of the state of our country. He wants some kind of civil war and you all are trying to give it to him. Wake up America and smell the bull shit!!
    Cindy Whittaker

    1. I am not sure why you think Bill Gates is such a hero. lllI don’t believe President Trump deserves your nasty comments. Neither of these men have anything to do with the subject. Oh, and bye the way you better get used to Trump because he is going to win unless the Democrats are able to steal the election.

  10. I found the supplements to be extremely healthful. I had stem cell therapy in November 2019, both knees. So far a great success. I took the liquid supplement & pill form for 90 days. My knees have done well, in addition I had an elective surgery in January, while still using the supplements. My recovery & healing was facilitated by the continued use. My surgeon agreed. In a totally unrelated area, & quite unexpected, my eyesight improved! I had been wearing 2.0 readers for several years for small print; after I completed all of the supplements, I became aware that I wasn’t wearing the readers any longer. The ONLY thing I had done differently was take those regenerating supplements. Idk if it works for everyone, but it makes sense &I am convinced the supplements were key. I’d buy them again if I feel the need.

    1. Cindy Whittaker

      You used stem cells to heal your knees and took the supplement after the surgery? Who did you use for your surgery?

  11. Lorraine gaglione

    Well I’m totally confused as who to trust for scientific info. I am purchasing other important vitamins from Dr Sears now I feel I should cancel all and look for a Dr I can trust

  12. Shitttt i just spent 140 on regenxx they have a 3 pack bundle hope it helps i have this hernaited dic that i had to get operated of course no choice but its killing me sigh… ill gove anything a try at this point…

    1. Herniated disc is a mechanical problem caused by posture and body habits. Even an operation won’t help you if you don’t correct your posture and body habits

    This is obviously very silly, but there’s another current issue that I think Dr. Knoepfler (and others) need to address. I’m a moderator on a Novel Coronavirus Facebook page, which basically consists of trying to be the voice of reason, talking people down from theories that Bill Gates and George Soros cooked up the virus in a lab as part of a plot to take down Trump, and basically checking the tinfoil hats. It’s a challenge! So I think you need to know that there is a new theory that has been popping up a lot. Basically, the premise is that scientists engineered the virus with CRISPR editing. (Not just that it escaped from a lab– this is a whole different version.) I really believe that the scientific community needs to start addressing this conspiracy theory. Because if scientists don’t do it, then politicians will. We’ve already seen this with Tom Cotton. We need people with credentials to step up to the plate and debunk some of the absolute craziness. I do think that the new coronavirus is a lot more serious than most people realize, but the last thing we need is bizarre theories running unchecked. Please think about seriously addressing these rumors.

    1. I’m here to learn about stem cells, not listen to your views on politics, CoVid, conspiracies or theories. “Methinks she doth protest too much.”

  14. Yes, exercise. Every time I play basketball or tennis I can feel something going on in my muscles a few hours later. And I usually sleep better Maybe it’s stem cells activation… who the hell knows?
