Product QnA

Q: What are the primary formulation applications of Zinc (4%) — from Guava Leaf?

A: Make it a same-time, with-meal habit and keep other variables steady. A practical start is 125–250 mg powder with your most reliable meal, giving roughly 5–10 mg zinc at a 4% assay. Hold the serving for two to four weeks before adjusting and log adherence rather than chasing higher totals. If you want a food pairing, include vitamin-C-rich items in that meal and keep tea/coffee away from the same window. Consistency beats tinkering, and one change at a time makes it easier to understand what actually routine over real-world days
