FAQ
Is Longevity vegan?
Is Longevity vegan?
Yes. Longevity is now 100% vegan!
We use Eferra™ lactoferrin—a bioidentical, animal product-free protein—to replace traditional dairy-derived forms.
Is the vitamin B12 in LONGEVITY methylated?
Is the vitamin B12 in LONGEVITY methylated?
Yes. We use methylcobalamin, the naturally active (methylated) form of B12. That means your body can use it immediately—no extra conversion steps required.
This is especially meaningful for people with genetic variations like MTHFR, which can make it harder to process other forms of B12. With methylcobalamin, you’re getting a bioavailable form your body can put to work right away to support energy, brain health, red blood cell production, and healthy methylation pathways.*
Is Longevity good for skin, energy, or brain health?
Is Longevity good for skin, energy, or brain health?
Yes—this formula supports skin clarity, daily energy, and long-term cognitive health.*
NAD+, glutathione, CoQ10, and B12 work together to fight oxidative stress, fuel mitochondrial energy, and promote cellular repair across key systems.*
What does NAD+ do in the body?
What does NAD+ do in the body?
NAD+ is a coenzyme your cells use to make energy, repair DNA, and regulate healthy aging.*
Levels naturally decline with age, stress, and poor sleep. Supplementing with bioavailable NAD+ helps restore cellular vitality—especially when paired with antioxidants like glutathione and CoQ10.*
