Laboratory Verification for Botanicals

Batch testing protects potency and consumer safety. Black elderberry extract requires high-performance liquid chromatography testing to quantify active polyphenols, while zinc bisglycinate requires infrared spectroscopy to confirm molecular bonding.

The Science Behind Chelation

Zinc bound to two glycine molecules passes intact through stomach acid into the duodenum. Standard zinc oxide or zinc sulfate breaks apart early, causing gastric distress and poor mineral uptake.

• Quality check: Fourier-transform infrared spectroscopy verifies the glycine chelate bond.
• Traceability: European Sambucus nigra berries tracked by harvest lot and regional origin.

Why This Matters Daily

Unbonded mineral salts bind to dietary phytates and leave the digestive tract unabsorbed. True bisglycinate chelation prevents mineral competition in the gut, ensuring steady plasma levels across 24 hours.
