NOW Supplements ADAM Men's Multivitamin is a comprehensive daily multivitamin designed specifically for men. It goes beyond basic vitamins and minerals, incorporating targeted ingredients like saw palmetto, lycopene, CoQ10, alpha lipoic acid, resveratrol, and grape seed extract. This makes it an excellent choice for men who want support for prostate health, heart function, and antioxidant protection in one formula.
The standout feature of this multivitamin is its science-based formulation. It includes CoQ10 for cellular energy and heart health, along with alpha lipoic acid and resveratrol, which are known for their antioxidant properties. The addition of saw palmetto and lycopene addresses common men's health concerns, while the B-vitamin complex supports energy metabolism.

This one-daily formula combines over 20 essential vitamins and minerals with a superfood blend, botanicals, and digestive support, making it a convenient choice for those looking to maintain their health as they age.
One of the standout features is its inclusion of digestive enzymes and probiotics, which not only aid in nutrient absorption but also promote a healthy gut.

Buying Guide: What to Look for in a Men’s Multivitamin
Before you choose between NOW ADAM and Rainbow Light Men’s One, consider these four practical factors. Each one can make or break your daily supplement routine.
1. Form and Swallowability
Multivitamins come in caplets, softgels, and veg capsules. NOW ADAM offers both veg caps (for those avoiding gelatin) and softgels (which are gentler on the stomach and easier to swallow). Rainbow Light Men’s One uses vegetarian caplets that are also easy to take. If you have a sensitive GI tract, the softgel version of NOW ADAM may be a better fit. If you prefer a smaller, smooth caplet, Rainbow Light might win you over.
2. Nutrient Profile and Special Ingredients
NOW ADAM is packed with saw palmetto, lycopene, CoQ10, alpha lipoic acid, resveratrol, and grape seed extract—targeting prostate health, heart function, and antioxidant protection. Rainbow Light Men’s One focuses on a men’s botanical blend plus digestive enzymes and probiotics. It also includes a potent B complex for energy metabolism. Which matters more? If prostate support is a priority, NOW ADAM leads. If you want digestion-friendly nutrients, Rainbow Light stands out. For a deeper look at how Rainbow Light compares to another top brand, see our Garden of Life Vitamin Code vs Rainbow Light comparison.
3. Serving Size and Convenience
Both brands offer a one-per-day serving, but NOW ADAM requires two capsules (veg caps) or two softgels daily, while Rainbow Light Men’s One is a single caplet per day. If you dislike swallowing multiple pills, Rainbow Light’s one-and-done approach is simpler. However, NOW ADAM’s two-capsule format allows for a broader nutrient profile in each serving.
4. Certifications and Quality Assurance
NOW supplements carry NPA A-rated GMP certification, meaning their manufacturing process is rigorously validated for potency and purity. They also offer Kosher and vegan options (veg caps). Rainbow Light uses simple, vegetarian ingredients free of common allergens like gluten, dairy, and artificial additives. Both brands prioritize quality, but NOW’s long history since 1968 and independent ownership add trust. If you need a vegan multivitamin, NOW ADAM veg caps are the clear choice.
Final Thoughts
After comparing forms, nutrients, convenience, and certifications, the best pick depends on your personal priorities. For men seeking comprehensive prostate and heart support with a science-backed formula, we recommend the softgel version of NOW Supplements, ADAM™ Men’s Multivitamin—it’s gentler on the stomach and includes saw palmetto, CoQ10, and lycopene. If you prefer a one-caplet daily routine with digestive enzymes and a botanical blend, go with Rainbow Light Mens Multivitamin One. Both are excellent choices that will serve you well in 2026.
Frequently Asked Questions
Which multivitamin is better for digestion: NOW ADAM or Rainbow Light Men’s One?
Rainbow Light Men’s One includes plant-sourced digestive enzymes and probiotics, making it a stronger choice for those with sensitive stomachs. NOW ADAM softgels are also easier on digestion than the veg caps, but they lack added enzymes. If digestion is your main concern, Rainbow Light leads.
Can I take these multivitamins on an empty stomach?

How do the nutrient profiles compare for energy?
Both provide B vitamins for energy metabolism, but Rainbow Light includes a potent B complex with choline and magnesium. NOW ADAM adds CoQ10 and alpha lipoic acid for cellular energy.
