Longevity Supplement FAQs
What are longevity supplements?
Compared to 'generic' supplements that contain ingredients to prevent vitamin deficiencies, longevity supplements target cellular pathways that directly impact how we age, supporting both health span (the number of years you’re healthy) and lifespan (the number of years you’re alive). They target at the cellular level to help replace certain nutrients depleted through the aging process and boost the production of various nutrients to slow down pathways that impact aging.
What are the best longevity supplements?
Supplements that support longevity, like anything related to nutrition, should be highly personalized to your specific health goals. Longevity supplements can be grouped into the following categories based on how they target cellular pathways within the body: antioxidants, metabolic regulators, caloric restriction mimetics, NAD+ precursors, NAD+ boosters, sirtuin activators, senolytics, steroids and hormones. For personalized recommendations, we suggest connecting with one of our Nutrition Advisors through our free nutrition service.
What are the best vitamins for longevity?
The best vitamins for longevity are dependent upon your health goals. However, the B vitamins, vitamin C and vitamin D have strong longevity-promoting profiles. At ProHealth, we have a variety of formulations that include vitamins and additional minerals, antioxidants, etc to help tackle all aspects of age-related concerns over the age of 40.
What's unique about ProHealth Longevity’s supplements?
Compared to other companies, all of our supplements are formulated with research-supported ingredients and dosages. All products are manufactured in FDA-registered, GMP-compliant facilities. Additionally, each product is third-party tested, with Certificate of Analysis’ available on our website to verify that they’re of the highest quality, purity and potency.
Does ProHealth sell age-reversal supplements?
Chronological-age reversal (the number of years you’ve been on this planet) is not possible. Biological-age reversal (how old your cells are) is possible. ProHealth’s NMN is the first NMN in the world proven to reverse biological age by 12 years in a double-blind, placebo-controlled, peer-reviewed, published, clinical trial.
