Rainbow Light Men’s One Multivitamin Supplement Review

Rainbow Light Men’s One is a soy-free, gluten-free, food-based multivitamin. It’s designed to boost energy and stamina, and promote heart, prostate, immune, and sexual health. Complete digestive support is also provided through plant-source enzymes and their fast-acting ProbioActive probiotic blend (Bacillus coagulans, 25 million CFU).

But with 1,667% of your Vitamin B-1 RDA in every 1 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 Men’s One to two other bestselling multivitamins; New Chapter Every Man’s One Daily Multi, and Centrum Silver Men Multivitamin/Multimineral. 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 Men’s One to balance your vitamin, mineral, Omega-3, probiotic, and protein intake.

Folic acid helps the body produce and maintain new cells, which is why a folic acid deficiency can cause anemia in both adults and children.

Fortunately, Men’s One has a higher level of folic acid than virtually any other multivitamin on the market (800 mcg). This includes other leading men’s multivitamins, such as GNC Mega Men Sport (400 mcg), and Optimum Nutrition Opti-Men (600 mcg).

In addition to folic acid, each 1-tablet serving contains high levels of vitamin K (100 mcg) and zinc (20 mg). Zinc is a mineral that helps keep the immune system strong, heal wounds, and supports normal growth.

One of the only multivitamin supplements with more zinc is GNC Mega Sport Men (25 mg per serving).

On the label, one of the claims is that Rainbow Light Men’s One boosts energy and stamina. Levels of vitamin B6 and B12 are certainly high enough to provide an energy boost (25 mg each), and higher than most multivitamins. But you can enjoy twice this amount with a serving of Mega Men Sport from GNC (50 mg vitamin B6 and 50 mg B12 per serving).

What sizes are available?

With a serving size of 1 tablet, each bottle provides you with 30, 90, or 150 servings. Multi-packs are also available on Amazon, where you can buy up to 300 tablets (2 packs of 150 tablets).

However, at the time of writing this review, the best value for money comes from the bottle of 150, not the multi-packs. Each serving was priced at $0.17, compared to $0.25 per serving if you bought two of these bottles in a multi-pack.

That’s why we always recommend calculating the average cost per serving, across all sizes, before making a final buying decision.

Rainbow Light Men's One Review Summary

Overall Review Rating

4.5 / 5

So, is Rainbow Light Men's One the best men's multivitamin on the market?

Almost all vitamins and minerals contained in Men's One are present at lower levels than GNC's Mega Men Sport multivitamin.

The amount of vitamin A is equal (5000 IU), but levels of vitamins B6, B12, and D, biotin, thiamin, and calcium are all 50% or less of what you'll find in the GNC supplement.

The difference is even greater when compared to the high-potency formula of Optimum Nutrition Opti-Men, which delivers twice as much vitamin A, 400% of the vitamin B12, and more than 600% of the vitamin E.

Overall, Rainbow Light Men's One delivers better value for money than the Vitafusion Men's gummy multivitamin, but delivers less vitamins and minerals than GNC Mega Men Sport and the high-potency Opti-Men supplement.

In addition to the basic vitamin and mineral levels, both Opti-Men and Men's One include proprietary formulas and further beneficial ingredients, such as enzymes.
