You know that feeling when your energy dips mid-afternoon, your focus blurs, and your skin starts to lose that youthful bounce? For men over 50, these signs often trace back to declining NAD+ levels. NAD+ is a crucial coenzyme in every cell, but it naturally decreases with age. That’s why so many turn to supplements like NMN (nicotinamide mononucleotide) and niacinamide (a form of vitamin B3). However, the market now offers advanced alternatives that combine multiple precursors for better results. In this guide, we compare two standout products: the Ashenutri NMNH Supplement and the Vitalitown 5 in 1 NAD+, NMN Supplement. We’ll help you decide which formula aligns with your health goals in 2026. If you’re also considering brain support, check out our comparison of bacopa vs phosphatidylserine for men over 50 for additional cognitive benefits.

Buying Guide: What to Look For in a NAD+ Supplement
NAD+ Precursor Blend vs Single Ingredient
The core of any NAD+ supplement is its precursor. NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are direct precursors, while niacinamide (nicotinamide) works through the salvage pathway. Some new formulas use NMNH, a reduced form of NMN that may offer better absorption. Which is right for you? A single-ingredient approach like pure NMN is straightforward, but a blend of multiple precursors (like NR, niacinamide, and L-tryptophan) can support NAD+ production through multiple pathways. The Ashenutri NMNH uses NMNH plus nicotinamide riboside, resveratrol, and quercetin. The Vitalitown 5 in 1 combines NR, niacinamide, L-tryptophan, trans-resveratrol, and quercetin. If you want comprehensive cellular support, a multi-precursor formula may be more effective.
Additional Synergistic Ingredients
Resveratrol and quercetin are often included alongside NAD+ precursors because they activate sirtuins (longevity proteins) and provide antioxidant support. Both products we review contain these two co-stars. However, the Vitalitown 5 in 1 also includes L-tryptophan, which participates in NAD+ synthesis via the kynurenine pathway. This extra ingredient may offer a more rounded approach.

Form and Serving Size
Capsule count and dosage matter for consistency. The Ashenutri NMNH provides 120 capsules (60-day supply at 2 per day). The Vitalitown 5 in 1 comes with 90 veggie capsules. Consider how many capsules you’re comfortable taking daily and how long the bottle lasts. Both are non-GMO and made in the USA. For those also seeking muscle support, see our list of best muscle supplements for aging men that can pair with NAD+ formulas.
Final Thoughts
If you prioritize a cutting-edge reduced NAD+ precursor with flush-free vitamin B3 and a 60-day supply, the Ashenutri NMNH Supplement is your best bet. On the other hand, if you want a comprehensive five-ingredient formula that includes L-tryptophan for additional NAD+ pathway support at a lower capsule count, go with the Vitalitown 5 in 1 NAD+, NMN Supplement. Both deliver quality ingredients from reputable brands. For more head-to-head supplement comparisons, explore our COMPARISONS category to find the perfect stack for your health.
Frequently Asked Questions
Is NMN better than niacinamide for NAD+?
NMN is a direct NAD+ precursor, while niacinamide supports NAD+ through the salvage pathway. Both are effective, but NMN may raise NAD+ levels more rapidly. However, multi-ingredient formulas that include both can offer synergistic benefits. For a deeper look at similar comparisons, see our analysis of Lion’s mane vs omega 3 for brain aging.
Can I take NMN and niacinamide together?
Yes, combining NMN and niacinamide is not only safe but may be beneficial because they use different pathways. Products like the Vitalitown 5 in 1 intentionally include both. Always follow the recommended dosage on the label.
What is NMNH and how does it compare to NMN?
NMNH is the reduced form of NMN. It may be more stable and better absorbed, potentially leading to greater NAD+ increases. Early research is promising, but more studies are needed. The Ashenutri NMNH uses this ingredient along with other precursors.
Which NAD+ supplement is best for men over 50 in 2026?
The best choice depends on your specific needs. For an innovative single-blend with NMNH, choose Ashenutri. For a five-ingredient comprehensive formula with L-tryptophan, go with Vitalitown. Both are expertly formulated for cellular energy and healthy aging.
