Product Quality Analysis

Purity and Formulation

Healthspan Formulas: Their NMN supplement is distinguished by its exceptional purity—containing absolutely no fillers, additives, or unnecessary ingredients. This pure formulation is particularly beneficial for those with sensitivities and ensures you're getting exactly what you're paying for: pure NMN and nothing else. The supplements are manufactured in GMP-certified facilities, ensuring pharmaceutical-grade quality control.

DoNotAge: While DoNotAge maintains strict quality standards and GMP-certified manufacturing, their NMN capsules contain the same ingredients, just at a higher price-point. This isn't necessarily negative, but it is worth consideration.

Absorption Technology

Healthspan Formulas: Their use of delayed-release capsule technology represents a significant advantage. These capsules are designed to bypass the harsh acidic environment of the stomach and release the NMN in the small intestine, where it can be more efficiently absorbed. This technology helps maximise the bioavailability of the active ingredient.

DoNotAge: Their NMN supplements use standard vegetable capsules. While these are certainly of good quality, they don't offer the potential absorption benefits of delayed-release technology, which may affect how effectively the body can utilise the NMN.

Product Range Comparison

Both companies offer a range of longevity-focused supplements, but with different approaches to their product portfolios.

Healthspan Formulas Range

Healthspan Formulas focuses on a carefully curated selection of the most scientifically-supported longevity compounds, including:

• NMN (Nicotinamide Mononucleotide)
• NMN Complex
  • With Quercetin
  • Pterostilbene
  • Resveratrol
  • Trimethylglycine (TMG) and B12
• Resveratrol
• Alpha Lipoic Acid
• CoQ10
• Magnesium Complex
• Specialised bundles targeting specific aspects of longevity

Their philosophy appears to be quality over quantity, focusing on well-researched compounds rather than offering a vast array of supplements.

DoNotAge Range

DoNotAge offers a broader range of products, including:

• NMN
• NMN Liposomal
• Resveratrol
• Fisetin
• Spermidine
• Quercetin
• Apigenin
• Various complex formulations
• Testing kits

Their approach seems to be offering a comprehensive selection covering most compounds mentioned in longevity research, giving customers a variety of options.

FAQs About NMN Supplements

Q: Is there a significant difference between NMN from different manufacturers if they all claim 500mg dosage? A: Yes, there can be meaningful differences. Purity levels, the presence of fillers or additives, manufacturing standards, and delivery systems (like delayed-release technology) can all affect the quality and effectiveness of the supplement, even at identical dosages.

Q: Why is there such a price difference between NMN supplements on the market? A: Price differences can be attributed to several factors: manufacturing standards, purity levels, capsule technology, company overhead costs, marketing expenses, and simply different profit margin strategies. Some companies, like Healthspan Formulas, prioritise making high-quality supplements more accessible, while others may maintain higher prices due to brand positioning or additional company costs.

Q: How important is delayed-release technology for NMN supplements? A: While not absolutely essential, delayed-release technology can potentially improve the absorption of NMN by protecting it from stomach acid and releasing it in the small intestine, where it can be more efficiently absorbed into the bloodstream.

Q: Do I need a membership or subscription to get the best value? A: Not necessarily. While some companies offer discounts through membership programmes, others provide value without requiring any membership or subscription. It's worth calculating the actual cost per day of supplementation after all discounts to make a fair comparison.

Q: How long does a typical NMN bottle last? A: This varies by brand. Healthspan Formulas and DoNotAge both provide 60 capsules per bottle, which constitutes a 2-month supply at the recommended dosage of one 500mg capsule per day. Some other brands may only provide a 30-day supply per bottle, so it's important to check not just the price per bottle but the price per day of supplementation.
