FDA warns vs ‘adulterated’ food supplement for men
The Food and Drug Administration (FDA) has warned men against taking an “adulterated” dietary supplement that boosts libido after it was found to contain sildenafil citrate—the same drug ingredient found in Viagra which is used to treat erectile dysfunction.
In FDA Advisory No. 2025-0452, the FDA said that based on laboratory analyses, Megaman Herbal Dietary Supplement for Men with lot number 24CA and an expiration date of March 11, 2026, tested positive for sildenafil citrate.
“The presence of the drug ingredient … deems the dietary supplement as adulterated, which is in violation of Republic Act (RA) No. 9711 (FDA Act of 2009) and RA 10611, otherwise known as the Food Safety Act of 2013,” it said.
It added that sildenafil citrate, which is a drug that requires a prescription from a physician, is prohibited in food supplements.
“It poses potential health risks to the unwary consuming public, especially those who have had a stroke, persons with heart problems, kidney problems, and low blood pressure,” the FDA said.
Side effects
Among its side effects if used without proper medical consultation are headache, diarrhea, dizziness or lightheadedness, urinary tract infection, priapism (prolonged erection), indigestion, nasal congestion, rashes, and changes in vision or sudden vision loss.
Individuals who took the “adulterated” Megaman capsules should see a doctor if they experience any of the side effects.
Based on its packaging, Megaman capsules should contain only ginseng root, maca root, tongkat ali root and horny goat weed—plants which are believed to have an aphrodisiac effect or naturally enhance sexual performance.
In 2018, the FDA issued an advisory warning that Megaman did not go through its registration process and had not been issued a certificate of product registration.
RA 9711 prohibits the manufacture, importation, exportation, distribution or sale of health products without proper FDA authorization.
