Each serving of Optimum Nutrition Opti-Men delivers a high-potency dose of 75+ ingredients, via their Nutrient Optimization System. This includes 1 gram of an Amino Men Blend, containing amino acids such as L-Glutamine, L-Arginine, and all three BCAAs (L-Leucine, L-Isoleucine, L-Valine).
But with 2500% of your Vitamin B6 RDA per 3 tablet serving, how do you know if this is a safe dose? What if you’re already taking a protein powder with its own multivitamin complex?
In this review we compare O.N. Optimum-Men to two of the best multivitamins on the market; Dr. Tobias Vitality, and One-A-Day Men’s Health Formula. This includes ingredients, dosages, cost per serving, price, and customer feedback from the thousands of reviews on Amazon.
We’ve also added recommendations for the best protein powder to combine with Opti-Men to balance your vitamin, mineral, Omega-3, probiotic, and protein intake.
Optimum Nutrition Opti-Men Ingredients
Compared to their Opti-Women supplement, the levels of vitamins and minerals found in Opti-Men have been increased. Generally the RDA for vitamins and minerals is based on age rather than gender, but it’s the added ingredients that make this particular multivitamin better suited to men.
The Viri Men Blend contains 50 mg of natural ingredients designed to support healthy testosterone levels. This includes Saw Palmetto Extract, which may boost testosterone (T) by preventing it from converting into dihydrotestosterone (DHT).
But there’s little scientific evidence to prove the ingredients in this blend have any real health benefits. Some anecdotal evidence suggests Damiana’s active compounds may block the conversion of testosterone to estrogen. But we’ve seen no evidence to back this up.
It’s a similar story with the 100 mg of Phyto Men Blend. Several studies have found green tea to have fat burning benefits, and there is some evidence to suggest hesperidin can help with blood vessel conditions, such as poor circulation.
Unfortunately, these sources also recommend consuming 500 mg of hesperidin daily to see any real benefit, which is well below the amount contained in Optimum Nutrition Opti-Men.

Save money with Amazon
If you’re looking to save money on your monthly supplement order, you might want to consider the Amazon Subscribe & Save program.
Subscribe & Save allows you to unlock savings of up to 15% on a wide range of sports nutrition products, including Optimum Nutrition Opti-Men.
You can save 5% with a subscription to 1 product, or save the full 15% by subscribing to 5 products, provided they’re all delivered to the same address. The delivery schedule can be set from monthly, up to once every 6 months.
Although 5 products might sound a lot, if you already supplement with a protein powder, multivitamin, creatine, BCAA, and glutamine, the savings can soon add up. But it’s best to order before you run out of your current supplements, because Amazon set the day of the month each order is sent (same day each month e.g. 14th.).
