Explore our comprehensive range of professional-grade wellness solutionsThe Science Behind Longevity & Anti-Aging
Aging isn't just about wrinkles—it's about energy, inflammation, and cellular decline. Our formulations like NAD+, Glutathione, and B Complex are designed to support mitochondrial health, tissue repair, detox, and hormone balance. Together, they help defend against the root causes of aging and keep your body performing at its best. Longevity isn't a myth—it's a science, and it starts here.
NAD+ levels decline by up to 50% by age 50, reducing cellular energy and DNA repair capacity (Harvard Medical School).
Glutathione decreases by 30–40% with age, weakening detox pathways and increasing oxidative stress (National Institutes of Health).
B vitamins lower homocysteine levels by 25%, reducing risk factors for cardiovascular aging and cognitive decline (American Journal of Clinical Nutrition).
Essential amino acids increase muscle protein synthesis by up to 60%, preserving lean mass critical for metabolic health (Journal of Nutrition, 2003).
Chronic inflammation is linked to 7 of the 10 leading causes of death, making anti-inflammatory support a foundational longevity strategy (CDC).

Certain products offered through Axentra Health require a licensed telemedicine consultation before purchase. If a product is marked as prescription-only, you will be prompted to complete a secure intake form and meet with one of our licensed medical providers to ensure the treatment is safe and appropriate for you. Axentra Health's telemedicine services are designed to offer accessible care across the U.S., but they are not a replacement for in-person evaluation in all cases. Your provider may recommend an in-person follow-up or local testing if needed.
