This Dr Jockers supplements review covers what the company sells online, what its own pages claim, and what published research says about the main ingredients. The short version: none of the product pages I read cites a trial showing weight loss, NIH has published research on some of these ingredients, but none of it shows weight loss from these products, and the company’s public record includes an F rating on its BBB profile and a 2020 FDA and FTC warning letter.

I am not a medical professional. Everything below is attributed to a page or study you can open yourself, and pricing is what the website showed on October 20, 2026. For the wider health picture, start with the supplements for women over 40 guide.

Who is Dr. Jockers and is Dr. Jockers legit?

The About page on drjockers.com gives his name as “Dr. David Jockers DNM, DC, MS” and describes him as a doctor of natural medicine. It lists the letters DNM, DC and MS and does not list a medical license. It also says he sells products through his own store, store.drjockers.com.

“Legit” is really three questions, so here is each one.

First, the Better Business Bureau. The BBB profile for Dr Jockers.com, LLC says the business is not BBB accredited and shows a rating of F. The profile lists two reasons for the F: “Failure to respond to 2 complaint(s) filed against business” and “2 complaint(s) filed against business.” The profile does not publish the complaints themselves, and I read it on October 20, 2026. The profile shows a BBB file opened 5/20/2020. A BBB rating says nothing about whether a supplement works, but BBB says the company did not respond to the complaints it lists.

Second, the FDA. On May 1, 2020, FDA and the Federal Trade Commission sent the company a warning letter about COVID-19 claims. The letter said the website offered Super C, Vitamin D/K2, Zinc Charge and ImmunoStrong Berry Liquid for uses it called unapproved and misbranded, and asked it to stop selling them for COVID-19 use. I did not check whether the letter has been closed out. The letter names a product called Vitamin D/K2, and I cannot tell whether it is the D3/K2 Power product covered below. It was about disease claims made in 2020. It is not a finding about weight loss or about whether any current product is safe.

Third, the store’s own statements about quality, covered further down. Those are the company describing itself, so I treat them as claims, not proof.

What does Dr. Jockers sell online?

The Dr. Jockers website sorts its offers into categories that include Allergies, Anti-Inflammatory, Blood Sugar, Candida, Digestive Health, Energy, Immune Health, Ketogenic, Magnesium, Men’s Health, Protein Powders, Stress Relief, Weight Loss and Women’s Health, plus books and support packs. Its header reads “Supplements You Can TRUST.”

The Weight Loss tag on the shop listed seven items on October 20, 2026: Amino Strong ($44.95), Bile Flow Support ($44.95), KetoBrain C8 MCT Oil ($34.95 for 16 oz), KL Support ($61.95 for 120 capsules), Super DZyme ($24.95 for 60 capsules), Thyroid Strong ($34.95 for 60 capsules) and ThyroLiver Protect ($44.95). The store itself files these under Weight Loss, and the listing carries no claim text for any of them.

Who makes them? The customer FAQ says the items are “generally globally sourced although they are US manufactured.” It does not name a manufacturer. The product pages did not name one either.

What do Dr. Jockers’ quality and testing claims say?

The FAQ states that “All products on DrJockers.com are FDA cGMP and NSF ANSI audited” and that “Raw materials and finished products are third party tested to identify heavy metals, pesticides, etc.” The About page says “Our products are tested for purity and effectiveness,” a quality claim for the whole line.

Those are statements from the seller, not an independent finding. The NIH Office of Dietary Supplements explains why that matters: dietary supplements do not require FDA premarket review or approval, and manufacturers are responsible for deciding that what they sell is safe and that label claims are truthful (fact sheet updated May 18, 2022). If testing matters to you, ask the company for the certificate of analysis for the exact lot you buy.

Do Dr. Jockers supplements work for weight loss?

I found no trial of any of these products showing weight loss. The NIH Office of Dietary Supplements fact sheet on weight-loss supplements says the best way to lose weight and keep it off is a sensible approach built on a healthy eating plan, reduced calories and moderate physical activity under the guidance of a health care provider. NIH is also the source for the points below.

The tag includes Amino Strong, an MCT oil and thyroid-named products, so there is no single ingredient to judge. The sections that follow take four product pages I read, only one of which (Amino Strong) is on that tag, starting with MegaSporeBiotic.

MegaSporeBiotic: what does the research show?

The MegaSporeBiotic page listed pricing of $66.95 for 60 capsules on October 20, 2026. It describes a blend of 5 Bacillus spores. The Supplement Facts panel is an image, so I cannot list the strains from the page text. The page says the product is “clinically shown” to recondition the gut and survive stomach acid, and it lists seven references, including a 2017 paper by McFarlin and colleagues. The “clinically shown” line cites Cutting 2011, listed on the page under the title ‘Bacillus probiotics,’ which is not described there as a clinical trial. The page’s general probiotic language also says probiotics can have positive effects, “including… helping with weight loss.”

That paper is a real trial. In the 2017 McFarlin trial in the World Journal of Gastrointestinal Pathophysiology, 75 apparently healthy men and women were screened. Those whose blood endotoxin rose at least five-fold after a meal were randomized to placebo or “a commercial spore-based probiotic supplement” containing five Bacillus species for 30 days. The probiotic group’s post-meal endotoxin fell 42% from its own starting level, while the placebo group’s rose 36%. The study was funded in part by Microbiome Labs, and the abstract does not name the product tested.

Notice what was measured: blood markers after a meal, in people selected because their endotoxin jumped. It was not body weight. For weight itself, the NIH fact sheet reviews pooled trials of probiotics. A review of 19 randomized trials in 1,412 participants found probiotics or synbiotics reduced waist circumference slightly (by 0.82 cm) but had no effect on body weight or BMI, with low to moderate quality evidence. A second meta-analysis NIH cites (14 trials, 881 adults) suggested an average loss of 0.54 kg in adults. NIH says effects might depend on strain, dose, duration and user characteristics, and that more research is needed.

The page shows 11 customer reviews, all in the top rating bracket. Those are testimonials, not trial data, and they do not improve the evidence.

D3/K2 Power: vitamin D, vitamin K and a blood thinner warning

The D3/K2 Power page listed $26.95 for 30 capsules on October 20, 2026. The page text lists 5,000 IU of vitamin D3, 150 mcg of vitamin K2 as MK-7, and 120 mg of magnesium as magnesium citrate. It also states that the product “is not to be used by anyone taking blood thinning treatments.”

That warning lines up with the research. The NIH vitamin K fact sheet (updated March 29, 2021) says warfarin and some other anticoagulants work against vitamin K, so people taking them need to keep their vitamin K intake consistent.

On weight, the NIH vitamin D fact sheet (updated June 27, 2025) says the available research does not support using vitamin D supplements to promote weight loss, and that clinical trials do not support a cause-and-effect relationship. The same fact sheet lists the Tolerable Upper Intake Level for adults as 100 mcg, which equals 4,000 IU a day. That is the figure to compare with the 5,000 IU listed on the product page, and a reason to take the product page to your clinician or pharmacist before buying.

Amino Strong: what is in it, and what is known?

The Amino Strong page at the store listed $44.95 for the Fruit Punch or Lemon flavor on October 20, 2026. It calls the product a “Powerful source of essential amino acids!” and describes a patent-pending blend developed through “Over 20 human trials.” I could not find any named trials, a Supplement Facts panel or gram amounts in the page text. The only amino acid it names is arginine, which it says “supports HGH release while you are sleeping.”

With no ingredient list or trial references that I could find in the page text, I cannot tell you what evidence applies to this exact product. For how amino acids in general have performed in studies of people who are dieting, see the guide on amino acids for weight loss.

One detail from the page: it says that under New York law the store cannot sell products associated with weight loss and muscle building to anyone under 18.

Brain Calm Magnesium: what the page says and what NIH says about magnesium

The Brain Calm Magnesium page listed $58.95 on October 20, 2026. It names three forms: di-magnesium malate, magnesium lysinate glycinate chelate and magnesium L-threonate (Magtein). I could not find a milligram amount per serving in the page text, and I found no kidney or medication warning there. It says Magtein is “the only form of magnesium proven in animal studies to cross the blood-brain barrier.” Most of the studies it cites are rodent or cell research. It also cites human sleep studies without saying who was enrolled, and mentions a human trial whose results it calls “publication forthcoming.”

The NIH magnesium fact sheet (updated January 6, 2026) says symptomatic magnesium deficiency from low intake is uncommon in otherwise healthy people because the kidneys limit how much magnesium is lost in urine. It sets the Tolerable Upper Intake Level for supplemental magnesium at 350 mg for adults and says high supplemental doses can cause diarrhea, nausea and abdominal cramping. Because I could not find the magnesium per serving in the page text, ask the company before comparing it with that limit.

How much does Dr. Jockers cost, and what is the return policy?

Pricing on the four pages ranged from $26.95 to $66.95. Orders over $49 ship free in the U.S. according to the website.

The return rules are worth reading before you buy, because two store pages word them differently. The refund policy says “Our policy lasts 60 days,” requires the item to be unused and in its original packaging, and says shipping costs are non-refundable. The FAQ says “We offer a full refund on any unopened product,” after you contact the sales team for approval. On both pages you pay return shipping. A supplement you opened and disliked may not qualify under either, so confirm with the company before opening.

Should you talk to a clinician before using Dr. Jockers supplements?

Yes, especially if you take a GLP-1 medicine, a blood thinner, a thyroid or diabetes medicine, or you are pregnant or nursing. Several items on the website are sold for thyroid, blood sugar or digestive uses, which is where a prescriber or pharmacist needs to see the label. Share the exact product page with them.

The FAQ also says customer support “cannot answer health related questions or give medical advice,” so that conversation has to happen elsewhere.

Is Dr. Jockers worth it overall?

Overall, judged by evidence, the honest answer is narrow. MegaSporeBiotic’s page cites a real trial, funded in part by Microbiome Labs, on blood markers, though the abstract does not name the product tested. For D3/K2 Power, NIH says the research does not support vitamin D supplements for weight loss, and the product page lists 5,000 IU, above NIH’s 4,000 IU adult upper level. Amino Strong and Brain Calm Magnesium make claims that I could not match to product-level data on their pages. If your goal is weight loss, NIH says the best approach is a sensible plan under the guidance of a health care provider. The guide to functional medicine supplements for weight loss covers the wider approach.

If you decide to find the products yourself, you can browse the Dr. Jockers shop and read each Supplement Facts panel against what your clinician says.

Frequently Asked Questions

Are Dr. Jockers supplements FDA approved?

No supplement is FDA approved the way a prescription drug is. NIH says dietary supplements do not need FDA premarket approval, and the maker is responsible for safety and truthful labeling. The store’s product pages carry the statement that the claims have not been evaluated by the FDA.

Is Dr. Jockers a medical doctor?

His About page lists the letters DNM, DC and MS and calls him a doctor of natural medicine. It does not list a medical license or an MD degree, so keep your own prescriber involved in any health decision.

Does Dr. Jockers have an FDA warning letter?

Yes. FDA and the FTC sent a warning letter dated May 1, 2020 about COVID-19 claims for four products. It concerned how they were marketed in 2020 and it did not address weight loss.

Can I return an opened Dr. Jockers supplement?

The refund policy asks for unused items in original packaging, while the FAQ promises a full refund on unopened product. Neither policy says an opened product is refundable, so contact the sales team before you open anything you are unsure about.

Can a teenager buy Amino Strong?

The product page says the store cannot sell products associated with weight loss and muscle building to anyone under 18 in New York, and shows a checkbox reading “By checking this box you verify that you are 18 years or older.”

Is it safe to take D3/K2 Power with a blood thinner?

The product page itself says it should not be used by anyone on blood thinning treatment, and NIH says people on warfarin need steady vitamin K intake. Ask your prescriber or pharmacist before combining them.
