Where This Grade Actually Gets Used?
Beverage brands are the ones asking us for stability data most often, so that's worth leading with: at the standard 3% dissolution ratio, this powder goes fully clear with no residue, and it held up through our 85°C/15-minute pasteurization run at ≥95% potency. That's the number formulators actually need before committing to a beverage line - not just "heat stable," but how much survives a real pasteurization cycle.
For capsules, tablets and powder blends, the main question we get is compatibility with other longevity actives. We've run it alongside NMN, resveratrol and CoQ10 in the same matrix without seeing separation or potency drift, so it's a safe pairing for combination anti-aging formulas.
Snack and bar producers care about a different number: baking stability. Ours holds ≥90% potency after 30 minutes at 150°C, which covers most fortified cereal and protein bar processes without reformulating around the ingredient.
On the cosmeceutical side, it's typically dosed at 0.1%–1% in leave-on products like serums and creams - the right level depends on your base pH, so we'd rather talk through your specific formula than quote one number that may not apply.
Pet nutrition brands use the same grade for senior-support formulas; no separate documentation is needed since it carries the same purity and safety testing as the human-grade material.
Why This Grade?
Dual-verified purity - every batch checked by both HPLC assay and titration, not a single test method
Documented process stability - ≥95% potency after pasteurization, ≥90% after high-heat baking (see data above), so you're not guessing how it performs in your actual process
Neutral sensory profile - white, odorless powder that doesn't require flavor masking in beverages
Formulation flexibility - proven compatible with NMN, resveratrol, and CoQ10 in combination products
Full compliance documentation - ISO22000, BRC, HACCP, KOSHER, HALAL, FDA, Non-GMO, plus Health Certificates, COO, and heavy metal reports available for customs clearance
