Zinc Dose Calculator (Picolinate vs Citrate vs Gluconate, By Form)

Calculate elemental zinc by form. “50 mg zinc picolinate” delivers different elemental zinc than “50 mg zinc oxide.” Includes RDA, common cold protocols, and the copper-depletion warning most labels don’t disclose.

Quercetin Dose Calculator (Allergies / Senolytic / CV)

Calculate quercetin dose by goal. Flavonoid found in onions, apples, capers. Three main use cases: allergies (mast cell stabilizer), senolytic protocols (with fisetin or dasatinib), cardiovascular / anti-inflammatory. Absorption is poor — form matters.
