When I first started exploring supplements to support my overall health and longevity, NMN (Nicotinamide Mononucleotide) quickly caught my attention. After some research, I decided to try California Gold Nutrition NMN, and I want to share my experience and insights to help you make an informed decision.

What Is NMN and Why I Chose It

NMN is a molecule that plays a key role in producing NAD+, a vital compound involved in energy metabolism and cellular repair. As I learned, NAD+ levels decline with age, so supplementing with NMN seemed like a promising way to support healthy aging and energy levels.

About California Gold Nutrition NMN

California Gold Nutrition offers NMN in capsule form, typically in 125mg or 250mg doses per capsule. I appreciated that their product is non-GMO, gluten-free, and made in a GMP-certified facility.

My Criteria for Choosing This NMN Supplement

  • Purity and Quality: I checked that the NMN was pharmaceutical-grade and free from fillers or additives.

While NMN isn’t an overnight miracle, the gradual benefits aligned with what I expected from a longevity supplement. I also experienced no side effects, which was very important to me.

Things to Keep in Mind Before Buying

  • Consult Your Doctor: NMN is generally safe, but I recommend checking with your healthcare provider, especially if you’re pregnant, nursing, or have existing health conditions.
  • Consistency Is Key: I found that regular daily intake is necessary to feel the benefits.
  • Storage: The capsules should be stored in a cool, dry place to maintain potency.
