Understanding supplements.
How do I evaluate what I'm actually buying — in the most adulterated aisle in the industry?
The 'male enhancement' market is, by FDA enforcement record, the most adulterated supplement category in existence: products spiked with undeclared sildenafil analogs, unapproved drug doses sold as herbs, and borrowed science on nearly every label. And yet two honest products exist — citrulline and standardized ginseng, both with RCTs. This chapter teaches the difference: named compounds at studied doses with functional endpoints, versus proprietary 'performance blends' whose contents the FDA keeps finding pharmaceutical.
Powders
Citrulline — the honest dose format
Capsules
Standardized ginseng extract
Softgels
Omega-3 — with fat, EPA counted
'Performance Blends'
The category this chapter retires
L-Citrulline (The Smart Route)
Bypasses the liver's extensive arginine breakdown — reaching the kidney intact, where it converts to arginine and then nitric oxide. Result: 3 g citrulline raises blood arginine MORE than much larger arginine doses. The trial dose: 3 g daily, in water, any time; powder for the dose math.
L-Arginine (The Direct Route That Isn't)
The NO precursor itself — but heavy first-pass metabolism means large doses (5 g+) for modest arginine rises, with more GI upset. Citrulline is the pharmacokinetic upgrade; arginine is the older route that made the same molecule harder to deliver.
Choosing the Right Form & Dose
Label literacy in this aisle is safety literacy:
- Citrulline math: 3 g daily in powder (the honest format) — check grams per scoop, not 'mg of blend.'
- Ginseng standardization: Korean red, ginsenoside-standardized, at the studied gram range — species and processing are the claim.
- Omega-3 counting: EPA+DHA per serving with fat — the long-game dose, honestly framed.
- The standing rule: any product promising 'performance' without a named, dosed, studied compound belongs in the red-flag section below — and if you use PDE5 inhibitors, your physician and every future pharmacist must know.
Red Flags to Watch For
The enhancement aisle is the industry's enforcement record. Be highly cautious of products that:
- Promise immediate or dramatic results from 'herbal' formulas — the FDA's adulteration findings live here: undeclared sildenafil analogs, dangerous with nitrates and unlabeled.
- Use proprietary 'performance blends' — when doses are hidden, neither you nor a physician can check interactions; in THIS category, that opacity can be lethal.
- Contain yohimbe/yohimbine — a real pharmacological agent with arrhythmia, anxiety, and blood-pressure risks; a prescription drug in some countries sold as a bark on this shelf.
- Claim to be a 'natural Viagra' — natural is a source, not a safety rating, and the borrowing of the drug's name is the confession.
