The men's health supplement category is one of the most enforcement-active in the industry. FDA and FTC have pursued brands for testosterone claims, erectile function claims, and prostate claims with consistent regularity. The category is also one of the most prone to drug-spiking — products found to contain undisclosed pharmaceutical ingredients including sildenafil (Viagra) analogs and testosterone precursors — creating ingredient-level risk layered on top of claim risk.
What FDA Permits for Men's Health Claims
Under 21 CFR 101.93(f), permissible structure/function claims in the men's health category include:
"Supports healthy testosterone levels already within the normal range"
"Promotes healthy male hormone balance"
"Supports healthy prostate function"
"Promotes healthy urinary flow"
"Supports healthy libido"
"Promotes healthy sexual function"
"Supports physical endurance and vitality"
"Promotes healthy sperm motility and count"
"Supports male reproductive health"
"Promotes healthy energy and stamina"
These claims describe support for normal male physiological function. They don't imply treatment of hypogonadism, benign prostatic hyperplasia, erectile dysfunction, or male infertility.
Where Men's Health Claims Cross the Line
Testosterone claims:
"Boosts low testosterone" — implies treatment of hypogonadism (low testosterone is a diagnosed condition)
"For men with testosterone deficiency" — disease population targeting
"Raises testosterone like TRT" — comparison to testosterone replacement therapy (a drug treatment)
"Natural testosterone replacement" — explicitly implies drug-equivalent treatment
"Treats andropause" — andropause (male menopause) is a named clinical condition
Prostate claims:
"Treats BPH" — benign prostatic hyperplasia is a named disease
"Reduces enlarged prostate" — implies treatment of BPH
"For men with prostate problems" — disease population targeting
"Reduces prostate inflammation" — inflammation in the prostate context is associated with prostatitis (a disease)
"Reduces PSA levels" — PSA is a prostate cancer biomarker; claims about PSA imply treatment of prostate cancer risk
Erectile function and sexual health claims:
"Treats erectile dysfunction" — ED is a named condition
"Natural Viagra alternative" — drug comparison; implies equivalent drug treatment
"Helps men with sexual dysfunction" — sexual dysfunction is a clinical diagnosis
"Increases sexual performance in men with ED" — disease population targeting
The "testosterone booster" category is not a regulatory safe harbor
"Testosterone booster" as a product category descriptor is not itself an authorized claim type. It is a marketing category that implies increasing testosterone levels. If the intended use is to boost testosterone in men with low testosterone (a disease state), the product is making an implied disease claim. If the intended use is supporting normal testosterone in healthy men, the claim language must reflect that framing.
The Drug-Spiking Problem
Men's health supplements — particularly those in the sexual enhancement subcategory — have historically been found to contain undisclosed pharmaceutical ingredients:
Sildenafil (Viagra) and analogues: FDA has issued dozens of warnings against sexual enhancement supplements found to contain sildenafil or novel sildenafil analogues not approved as drugs or listed as supplement ingredients
Tadalafil (Cialis) analogues: Same issue as sildenafil — frequently found in undisclosed form in sexual enhancement products
Testosterone or testosterone precursors: Some products have been found to contain testosterone or synthetic testosterone analogues not disclosed on the label
These are not claim violations — they are adulteration violations. A product containing an undisclosed drug ingredient is adulterated under 21 U.S.C. 342(f). Ingredient testing of finished products, particularly in the sexual enhancement category, is essential brand protection.
Saw Palmetto and Prostate Claims
Saw palmetto has clinical evidence for effects on urinary symptoms associated with BPH. Structure/function claims about saw palmetto supporting healthy urinary flow and prostate function are potentially permissible. Claims about treating BPH symptoms, reducing prostate size, or managing prostate disease are disease claims.
Men's health compliance requires ingredient testing, not just claim review
Truli reviews men's health supplement claims for testosterone disease claims, prostate disease language, and erectile function drug comparisons — and flags the ingredient categories with the highest drug-spiking risk for additional testing verification. Claim compliance and ingredient integrity are both active issues in this category.
