EFFECTIVELY RAISE NAD+ LEVELS - NMN enters the cells via a newly discovered pathway (Slc12a8 protein) in order to boost NAD+ levels which fall as we age. MADE AND TESTED IN THE USA - Our NMN capsules are manufactured and tested right here in New York. Testing is available upon request. ANTI-AGING SUPPLEMENT - As we age, NAD+ levels fall. This can lead to having less energy, weight gain, and decrease blood flow. NMN helps boost NAD+ levels to slow the aging process.
