CB-1 Weight Gainer Review

CB-1 Weight Gainer’s official website cites an “8-week randomized, controlled clinical trial” showing users gained an average of three pounds — but provides no link to the study itself, and no independent trace of it could be found anywhere else. This CB-1 Weight Gainer review checked what’s actually verifiable behind the claims.

How We Researched This CB-1 Weight Gainer Review

This review checked the published research on zinc, vitamin D3, and Echinacea specifically, the National Advertising Division’s 2013 recommendation against CB-1’s marketing claims, and the real terms behind its automatic “success program” billing.

CB-1 Weight Gainer Review: What Is It?

Made by Supragenix (founded 2010, Orem, Utah), CB-1 Weight Gainer is marketed to underweight individuals, combining vitamin D3, zinc, Echinacea, soy lecithin, and a proprietary “Maximum Strength Weight Gain Blend” of isobutylamides, claimed to increase appetite and regulate metabolism.

What the Research on Key Ingredients Shows

• National Institutes of Health: vitamin D3 is genuinely essential for bone health, though no research connects it to weight gain specifically.
• NIH Office of Dietary Supplements: zinc genuinely supports several bodily functions, including immunity and muscle repair, though again with no direct link to weight gain.
• National Center for Complementary and Integrative Health: Echinacea purpurea is likely safe short-term, with traditional uses for cold and flu — no connection to weight gain was found in any of the ingredient research.

An Unverifiable Central Claim

This is the central issue: CB-1’s marketing rests on a specific clinical trial claim — three pounds gained on average over eight weeks — but the company provides no link to the actual study, and no independent trace of it exists. Not a single ingredient in the formula has direct research connecting it to weight gain.

A Real, Documented Regulatory Finding

On October 7, 2013, the National Advertising Division specifically recommended Supragenix discontinue certain CB-1 advertising claims, including the claim that “CB-1 produces an actual increase in body mass that you keep when you stop taking it, not just temporary water weight” — a direct, documented regulatory rebuke of this exact marketing language.

A Real Automatic Billing Concern

Purchasing CB-1 automatically enrolls you in a “success program” that bills $49.98 plus shipping monthly unless actively canceled — a genuine, documented customer complaint pattern worth knowing before your first purchase.

A Telling Absence in Negative Reviews

Searching negative reviews specifically for side-effect mentions turned up essentially none — but combined with widespread reports of no noticeable benefit either, this suggests a genuinely weak, likely ineffective formula rather than a safe one.

Does CB-1 Weight Gainer Work?

No ingredient in the formula has direct research support for weight gain specifically, the company’s own cited clinical trial can’t be independently verified, and a formal advertising body has already flagged its core marketing claim. Combined with widespread “no effect” reports, the evidence doesn’t support the product’s central promise.

Who CB-1 Weight Gainer Actually Makes Sense For

Given the unverifiable clinical claim, the NAD’s documented advertising finding, and the automatic billing structure, this is difficult to recommend for anyone. Underweight individuals should consult a doctor for evaluation and legitimate weight-gain strategies instead.
