Optimum Nutrition Opti-Men Multivitamin - 150 Tablets
by Optimum Nutrition
A sports-oriented men's multivitamin from the world's best-selling sports nutrition brand, featuring over 75 active ingredients across four proprietary blends: Amino Men, Phyto Men, Viri Men, and Enzy Men. Each three-tablet serving delivers a full spectrum of vitamins and minerals plus 1g of free-form amino acids and 18 fruit and vegetable concentrates. The 150-tablet bottle provides 50 servings. It is one of the most popular gym-focused multivitamins in the UK, widely available at supplement retailers and gym shops.
AI Review Summary
Optimum Nutrition Opti-Men is a popular sports multivitamin with an impressive 75+ ingredient count, though the proprietary blend approach means many of those ingredients — particularly the amino acids and botanical extracts — are present in doses too small to be individually effective. The core vitamin and mineral profile is decent, and the Informed Sport certification is valuable for competitive athletes. However, the three-tablet-per-day serving, use of cheaper B-vitamin forms (cyanocobalamin, pyridoxine HCl), and premium price make it harder to justify versus more transparent alternatives.
Pros
- +Informed Sport certified — safe for drug-tested athletes
- +Solid core vitamin and mineral doses
- +Brand recognition and widespread UK availability
- +Includes fruit, vegetable, and botanical blends
Cons
- -Proprietary blends hide individual ingredient doses
- -Uses cheaper B-vitamin forms (cyanocobalamin not methylcobalamin)
- -Three tablets per serving is inconvenient and the tablets are large
Best For
Watch Out
- !Proprietary blend amino acid doses are too low to provide meaningful sports benefits

Clean Label Analysis
The excipient list is typical for a heavily compressed multi-ingredient tablet. Magnesium stearate and silica are present as standard flow agents. The proprietary blend approach makes it difficult to assess individual ingredient doses within the blends. Acceptable for the product type but not the cleanest formulation.
