NMN Availability at Costco: What You Need to Know
For many health-conscious consumers, Costco is a one-stop shop for a wide variety of wellness products. However, when it comes to highly specific and niche supplements like Nicotinamide Mononucleotide (NMN), the answer to its availability is not always straightforward. The situation can differ significantly based on your geographical location, particularly between the United States and Canada.
Costco Canada vs. Costco US: A Regional Divide
The most significant factor determining if you can purchase an NMN supplement at Costco is your country of residence. Canadian members have, at times, had access to NMN supplements, such as the webber naturals NMN (nicotinamide mononucleotide) 150 mg product. This item was reportedly sold online through Costco.ca and was a exclusive product for the Canadian market. This demonstrates that Costco's inventory can be region-specific, with certain supplements being available in one country and not in another.
In contrast, a search of the American Costco website (Costco.com) and in-store inventory has generally not yielded positive results for NMN supplements. The US market has seen significant regulatory challenges and reclassification issues concerning NMN, which has impacted its availability. Specifically, a regulatory shift occurred in 2021 when a company sought to move NMN's classification from a dietary supplement to a drug. While the reclassification effort has not been finalized, it has created a period of uncertainty and limited availability on major retail platforms in the United States, including Amazon and, by extension, potentially Costco.
Factors Influencing Supplement Inventory at Costco
Costco's selection of dietary supplements is influenced by several key factors. Understanding these can help explain why NMN might or might not be on the shelves.
- Regulatory Changes: As seen with the FDA's scrutiny of NMN in the US, changes in regulatory status can cause retailers to pull products from their inventory to avoid legal complications.
- Supplier Partnerships: Costco often sources products from a limited number of trusted suppliers. If a specific NMN supplier does not have a partnership with Costco, the product will not be available.
- Regional Demand and Exclusivity: Products may be offered exclusively in certain regions based on market research or specific supplier deals, like the case of Webber Naturals NMN in Canada.
- Sales Volume: Costco's business model relies on high-volume sales of a limited number of products. Niche supplements like NMN may not always meet the required sales metrics for a national or international inventory spot.
What is NMN and Why Is It Sought After?
Nicotinamide Mononucleotide (NMN) is a derivative of vitamin B3 that is a direct precursor to Nicotinamide Adenine Dinucleotide (NAD+). NAD+ is a critical coenzyme found in every cell of the body and is essential for hundreds of metabolic processes. Levels of NAD+ naturally decline with age, and many believe that supplementing with NMN can help replenish NAD+ stores.
The potential benefits of NMN have garnered significant attention in the anti-aging and longevity communities. These purported benefits are associated with boosting cellular energy and supporting healthy aging processes, which makes NMN a highly sought-after supplement.

Alternative Retailers for Sourcing NMN
If you find that your local Costco or its online store does not carry NMN, you have several reliable alternatives. These options often specialize in a broader range of dietary supplements and are not as susceptible to the same inventory fluctuations as a general retailer like Costco.
Specialized Online Supplement Stores: Many online retailers focus exclusively on health and wellness products, including advanced supplements like NMN. These platforms often carry products from numerous reputable brands, providing a wider selection than a typical retail store.
Direct-from-Manufacturer Websites: Some NMN brands sell directly from their own websites. This can be a reliable option, as it ensures product authenticity and often provides the most up-to-date information.
Online Marketplaces: While availability can fluctuate due to regulatory changes, major online marketplaces sometimes list NMN from third-party sellers. It's crucial to vet the seller and check for quality certifications when purchasing through these platforms to ensure product purity and legitimacy.
Conclusion
For Costco members, the availability of NMN supplements depends heavily on location. While Canadian Costco websites have offered NMN in the past, it is not a consistently stocked item in the US, largely due to ongoing regulatory changes. For a more reliable sourcing option, consumers are better off exploring specialized online retailers or purchasing directly from NMN manufacturers. Always research the brand and product carefully to ensure you are getting a high-quality supplement that meets your needs.
