Zinc (4%) — from Guava Leaf

With-Meal Capsule: 125–250 mg with food provides ≈5–10 mg zinc (4% = 40 mg/g). Keep the same mealtime daily for consistency.

Sachet To-Go: Pack 125–250 mg sticks; mix into citrus water or smoothies for a simple, repeatable habit.

Gummies: To deliver ≈2.5–5 mg zinc per 4 g gummy, use ≈62.5–125 mg powder (≈1.6–3.1% w/w); pilot flavour/acid balance.

Smoothie Add-In: 150–200 mg into a protein-forward smoothie at lunch for an easy daily stack.

Stack Idea: Pair the serving with vitamin-C sources and keep high-dose iron/calcium in a different window; adjust one variable at a time and track comfort.

Plant-Derived Source: Guava leaf origin suits clean-label builds.

Predictable Dosing: 4% assay simplifies mg math across formats.

Format-Friendly: Neutral taste and fine texture work in capsules, gummies, sachets and smoothies.

Clean & Compact: Standardized strength supports tidy formulation without stimulants.

Serving Size: 1 capsule or scoop (≈ 125–250 mg powder)

Ingredients: Zinc (4%) Extract Powder (from Psidium guajava leaves)

Does Not Contain: Added sugar, caffeine, artificial colours

Allergen Information: Vegan; gluten-free; dairy-free. Leaf-derived; review if sensitive to Myrtaceae-family plants.

Usage Recommendation: Take 125–250 mg once daily with meals (≈5–10 mg zinc). If stacking with other actives, add one change at a time and space ~90 minutes from medications as a routine practice.

Storage Advice: Store cool, dry & dark. Keep tightly sealed away from direct sunlight.

Keep Away From Children

Q: How do I place plant-derived Zinc (4%) into a simple daily routine?

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 supports your routine over real-world days.

Q: What’s the practical difference between guava-leaf zinc and common mineral salts for formulation?

A: This ingredient supplies standardized zinc within a botanical leaf matrix from Psidium guajava, which many formulators prefer for clean-label positioning and a familiar source story. Conventional salts (e.g., zinc gluconate or citrate) deliver higher potency per gram and very compact dosing but can bring acid balance or taste considerations. Choose by build and audience: capsules favour precision and small servings, while gummies and sachets favour ease and adherence. Whatever you pick, lock timing with meals, pilot small batches for flavour/uniformity, and avoid frequent product switches that blur evaluation and complicate SOPs.

Q: How do I set gummy strength without overcomplicating the formula?

A: Decide the per-gummy zinc first—2.5 or 5 mg—then back-calculate powder at 4% (40 mg per gram). That’s ≈62.5 mg or ≈125 mg powder in a 4 g pectin gummy (≈1.6–3.1% w/w). Keep acids and flavours consistent, disperse thoroughly to avoid hot spots, and document every batch variable. Store cool and dry; moisture and heat can affect colour and actives. Run a small stability check (taste, colour, assay) before scaling, then lock your SOP once pilots meet sensory and uniformity targets you can reproduce across production runs.

Q: Can I stack Zinc with vitamin C or other minerals without making the plan complicated?

A: Yes—anchor one serving first: 125–250 mg Zinc 4% with a consistent meal for two to four weeks. If adding vitamin C, keep it in the same meal for a simple pairing; keep high-dose iron or calcium in another window if you want a cleaner read on zinc. Leave ~90 minutes from medications as a general routine practice. Track comfort, adherence, and workflow friction (capsule vs gummy vs stick) in a simple log. Adjust gradually rather than making multiple changes at once so you can evaluate results clearly.
