Its sales pages are unusually honest, but in studies these ingredients produced only about a kilogram of extra weight loss, mostly at higher doses, and FIMAVYN itself has never been tested.

What FIMAVYN is
FIMAVYN is a dietary supplement sold at fimavyn.com, with ClickBank processing the order. The bottle says “Metabolic Activation” and “Healthy Weight & Energy Support”; it holds 60 vegan capsules, and the label says to take two a day with water. It launched in the autumn of 2026: its terms are dated September 2026, and Bing searches for its name only began in early October. The seller’s terms name the responsible business as a small company registered in Brazil, and orders are shipped and returned through a fulfilment warehouse in Aurora, Colorado. For now it ships only to the continental United States.
What the label shows
Per two capsules, the label lists:
- Zinc (as zinc gluconate) 11 mg and chromium (as chromium picolinate) 100 mcg
- Alpha-lipoic acid 150 mg
- Green tea leaf extract 150 mg (98% polyphenols, 80% catechins, 50% EGCG)
- Berberine HCl 100 mg (from Berberis aristata root, 97% berberine)
- Resveratrol 40 mg (from Japanese knotweed root extract, 200:1)
- A 112 mg proprietary blend of milk thistle seed extract (80% silymarin), cayenne, Asian ginseng (8% ginsenosides) and banaba leaf extract (2% corosolic acid)
This is more open than most supplements in this market: six of the ten ingredients have an amount and an extract strength, and the label is shown on the sales page before you buy. Only the four herbs in the small blend have no individual amounts.
How it is sold
FIMAVYN’s pages are unusually restrained for a ClickBank offer. They show no customer testimonials and say so; they do not promise a number of pounds or a time frame; and the “science” section links to a meta-analysis for each dosed ingredient while stating that the research is “not finished-product proof” and that study doses can differ from the label. The affiliate rules forbid fake reviews, guaranteed outcomes and pages that pretend to be the official site. A few things still lean towards marketing: the “Metabolic Activation” name, a “Best results!” banner on the six-bottle offer, and a terms page that still carries pre-launch wording about “no live checkout”, although the checkout works.
What the research shows for its ingredients
- Alpha-lipoic acid (150 mg): a 2017 meta-analysis of randomized trials found about 1.3 kg more weight loss than with a placebo. The trials used 300 to 1,800 mg a day, two to twelve times the amount in FIMAVYN.
- Chromium (100 mcg): a 2019 meta-analysis of 21 trials in people with overweight found about 0.75 kg more weight loss, mainly in trials of 12 weeks or less, and concluded that its clinical relevance remains uncertain.
- Berberine (100 mg): a 2026 meta-analysis of 23 studies found about 0.9 kg more weight loss. Berberine studies commonly use several hundred milligrams to 1.5 grams a day, far more than 100 mg.
- Green tea extract (150 mg) and resveratrol (40 mg): reviews of trials report small and inconsistent changes in weight measures, varying with dose and extract.
- Zinc (11 mg): the full daily value; effects on weight in trials are small and mixed.
- Milk thistle, cayenne, ginseng and banaba: share 112 mg, so each is present in a small amount; banaba’s corosolic acid is studied mainly for blood sugar.
Put together, even the studied doses of these ingredients produced weight changes of around a kilogram, and FIMAVYN combines mostly lower doses in one capsule that has never been tested. Several of them, chromium, berberine, alpha-lipoic acid and banaba, are also sold for blood sugar; FIMAVYN does not make that claim.
Who should check with a doctor first
- Diabetes medicines: berberine and alpha-lipoic acid can lower blood sugar, so combined with diabetes medicines they could push it too low.
- Other regular medicines: berberine affects liver enzymes that clear some drugs, and ginseng can interact with blood thinners.
- Pregnancy and breastfeeding, and under 18s: the label says it is not for them; berberine is not considered safe in pregnancy.
- Liver problems: green tea extracts have been linked to rare liver injury at high doses. FIMAVYN’s 75 mg of EGCG a day is low, but stop and see a doctor if you notice dark urine, yellow skin or eyes, or stomach pain.
- Stomach upset: berberine and cayenne can cause cramps, constipation or diarrhoea in some people.
What helps with weight
No supplement does much on its own. A steady calorie deficit built around protein, fibre and fewer ultra-processed foods, regular activity including strength training, and enough sleep make the real difference. For people with obesity or related conditions, doctors can now offer medicines with far larger effects than any supplement. Our slow metabolism guide and blood sugar guide go into more detail.
Price, shipping and guarantee
One bottle costs $69 plus $9.99 shipping; three cost $177 ($59 each) and six cost $294 ($49 each), both with free shipping. The “save 14%” and “save 29%” badges compare with the single-bottle price, not with an inflated crossed-out total. Every package includes four digital guides. It is a one-time payment, not a subscription, and orders ship only within the continental United States, typically in 3 to 5 business days. Prices were checked on the seller’s order page on 27 October 2026. The guarantee is a minimum of 60 days with no questions asked; email support before returning anything, and expect to pay the return postage. Our FIMAVYN buying guide covers ordering and refunds step by step.
Realistic expectations
FIMAVYN tells you what is in it, which is more than most products in this market do. Based on its ingredients and doses, expect little or no change in weight from the capsules alone. If you want to try it as one small part of a wider routine, the single bottle and the 60-day guarantee keep the risk low; if you take diabetes or other regular medicines, ask your doctor first.
🧪 Key Ingredients
What is in the formula, with a short note on each ingredient:
🌿 Berberine
Berberine is a bioactive alkaloid found in several traditional medicinal plants, studied mainly for its effects on blood sugar and cholesterol. It is widely used as a natural supplement to support healthy blood sugar levels, improve cholesterol profiles, and assist in weight management.
🌿 Chromium
Chromium is a trace mineral that may enhance the action of insulin and might play a role in the metabolism of carbohydrates, fats and proteins. It is widely used in supplements to support healthy blood sugar levels and improve body composition.
🌿 Green Tea Extract
Green tea extract is a highly concentrated form of the Camellia sinensis plant, rich in bioactive polyphenols and EGCG. It is a popular supplement studied mainly for weight, cholesterol and blood sugar, with modest results so far.
🌿 Milk Thistle (Silymarin)
Milk thistle is an herbal supplement made from the seeds of the Silybum marianum plant, valued for its active mix of compounds called silymarin. It is widely used for liver health, but human trials have not clearly shown that it treats liver disease.
🌿 Panax Ginseng
Panax Ginseng, also known as Korean or Asian Ginseng, is a root that has been used in traditional medicine for centuries to restore vitality and balance. Modern research has studied it for possible effects on thinking, fatigue, and physical performance, with mixed results so far.
🌿 Resveratrol
Resveratrol is a naturally occurring polyphenol found in red grapes, berries and peanuts, known mainly for antioxidant effects seen in lab studies. It is widely researched for possible heart, metabolic and anti-aging effects, but human trials are small and their results are mixed.
🌿 Zinc
Zinc is an essential trace mineral that is required for the activity of hundreds of enzymes in the human body. It is fundamentally essential for maintaining a robust immune system, facilitating protein synthesis, and supporting healthy cellular metabolism.
🌿 Alpha-Lipoic Acid (150 mg)
About 1.3 kg extra weight loss in a 2017 meta-analysis of trials using 300 to 1,800 mg a day.
*Always consult with your physician before starting any new supplement.

Frequently Asked Questions
FIMAVYN is a new two-capsule dietary supplement sold through ClickBank at fimavyn.com as “Metabolic Activation” for healthy weight and energy. A bottle holds 60 vegan capsules.
Per two capsules: zinc 11 mg, chromium 100 mcg, alpha-lipoic acid 150 mg, green tea extract 150 mg, berberine 100 mg and resveratrol 40 mg, plus a 112 mg blend of milk thistle, cayenne, Asian ginseng and banaba leaf.
It has never been tested. In meta-analyses its main ingredients produced about a kilogram of extra weight loss compared with a placebo, mostly at higher doses than FIMAVYN contains, so expect little change from the capsules alone.
Its doses are moderate, but berberine and alpha-lipoic acid can lower blood sugar and berberine can interact with some medicines. The label says it is not for under 18s or pregnant or nursing women; ask a doctor first if you take regular medicines.
FIMAVYN does not claim to, but chromium, berberine, alpha-lipoic acid and banaba are studied for blood sugar. If you take diabetes medicines, ask your doctor before using it, because the combination could lower your blood sugar too much.
Two capsules a day with water, as the label says. One bottle lasts 30 days.
Yes, it is a real product sold through ClickBank, with a published label and a 60-day guarantee, and its sales pages are more honest than most. Its effects on weight are likely to be small.
One bottle costs $69 plus $9.99 shipping, three cost $177 and six cost $294, both with free shipping. It is a one-time payment, and every package includes four digital guides.

See Why Everyone's Choosing This →How we scored FIMAVYN
Five weighted criteria — see our full methodology.
Whether the label discloses how much of each ingredient it contains, rather than hiding amounts inside a proprietary blend.
Whether the finished product has been tested in a published trial, or the claims rest on research into individual ingredients.
Monthly cost on the three-month package, the shortest course most vendors recommend (the single price for one-off digital products), compared against the rest of the category.
Length of the refund window measured against the trial period the vendor itself recommends.
How the product is sold: sales channel, checkout upsells, subscription defaults and how clearly the offer is presented.
Transparency: the label gives the amount and extract strength of six of its ten ingredients; only a 112 mg blend of milk thistle, cayenne, Asian ginseng and banaba is undisclosed. Evidence: FIMAVYN itself has never been tested, and its ingredients produced only about one kilogram of extra weight loss in meta-analyses, mostly at higher doses than here. Buying practices: unusually restrained, with no testimonials, no weight-loss promises and research presented with honest caveats; points off for the “Metabolic Activation” and “Best results” framing, leftover pre-launch wording in its terms, and a return process that needs approval first.
Final Verdict
FIMAVYN is one of the more honest offers we have reviewed. Its label shows the amount of six of its ten ingredients, its pages publish the Supplement Facts before you buy, there are no testimonials or before-and-after promises, and its own reference section says that research on individual ingredients is not proof that the finished product works.
That honesty also shows the limits. In meta-analyses, alpha-lipoic acid, chromium and berberine each produced around a kilogram of extra weight loss compared with a placebo, usually at higher doses than FIMAVYN contains, and the product itself has never been tested. It is unlikely to change your weight much on its own. If you take diabetes medicines, ask your doctor first, because berberine and alpha-lipoic acid can lower blood sugar. For meaningful weight loss, diet, activity and, where appropriate, medical treatment do far more.
