FAQ
Why choose Sunny Within Longevity?
Why choose Sunny Within Longevity?
Longevity is a first-of-its-kind daily supplement delivering bioavailable NAD+ and glutathione—two powerful nutrients that support energy, detox, and healthy aging at the cellular level.*
Unlike most formulas that use precursors or single ingredients, Longevity delivers a full 7-in-1 stack with CoQ10, B12, lactoferrin, and more—all designed to fuel your mitochondria, brain, and skin from within as you age.
What Makes Your NAD+ and Glutathione More Absorbable?
What Makes Your NAD+ and Glutathione More Absorbable?
We use patented Direct Precision Technology® to bind NAD+ and glutathione to vegan lactoferrin, a smart protein that helps these nutrients pass through the gut lining and into your cells.*
This delivery system bypasses common degradation issues, so you get more active ingredients exactly where your body needs them—without IVs or megadoses.*
What Is Lactoferrin, and Why Do You Use It?
What Is Lactoferrin, and Why Do You Use It?
Lactoferrin is a human-identical protein that promotes gut health, immune balance, and nutrient absorption.*
We use Eferra™ vegan lactoferrin, which mimics the powerful bioactivity of colostrum without any animal-derived ingredients. It also plays a starring role in our delivery system by enhancing the absorption of NAD+ and glutathione.*
Why Do You Use Avocado Oil?
Why Do You Use Avocado Oil?
Avocado oil is the nutrient-rich fat that powers our liposomal delivery system. While other liposomal brands use cheap oils with little nutritional benefits, we opted for certified organic avocado oil sourced from Mexico. No cutting corners here.
It’s rich in oleic acid and antioxidants—supporting heart, skin, and hormone health while helping your body absorb fat-soluble nutrients like CoQ10, vitamin D, and more.*
