How to read our product information and sources ↗

Nutrient reference

Zinc

Reference for: Zinc. Source presentation: oral nutrient reference. Source route: oral.

Biological role

Zinc participates in the catalytic activity of numerous enzymes and contributes to protein and DNA synthesis, cell signaling, cell division and normal immune function.

Absorption and disposition

Zinc balance depends on intestinal absorption, secretion into the gastrointestinal tract and reabsorption. Fractional absorption falls as intake rises. Much of the body zinc pool is in muscle and bone. This nutrient-level reference does not establish the absorption rate or bioavailability of a particular zinc salt or combination.

Nutrient-level summary from NIH. Absorption and disposition describe general oral nutritional physiology, not a pharmacokinetic or bioequivalence study of this finished product.

Nutrient reference

Calcium

Reference for: Calcium Carbonate. Source presentation: oral nutrient reference. Source route: oral.

Biological role

Calcium provides the mineral structure of bone and teeth. Ionized calcium also participates in muscle contraction, nerve signaling, blood coagulation and hormone secretion.

Absorption and disposition

Intestinal uptake occurs by vitamin-D-dependent active transport and passive diffusion. The absorbed fraction depends on intake and formulation. Calcium carbonate is more dependent on gastric acid than calcium citrate. Most body calcium is held in the skeleton, which is continually remodeled and acts as a reservoir. These nutrient data do not establish this product's bioavailability.

Ingredient-level reference

Alfacalcidol

Reference for: Alfacalcidol. Source presentation: SOFT CAPSULE. Source route: oral.

Mechanism of action

Alfacalcidol is rapidly converted in the liver to 1,25-dihydroxyvitamin D, which regulates calcium and phosphate metabolism. This conversion bypasses the impaired renal activation step described in the reference.

Pharmacokinetics

The reference describes passive, nearly complete absorption in the small intestine and rapid hepatic activation. It reports an alfacalcidol half-life of approximately 4 hours, while the pharmacological effect lasts 3–5 days. These are distinct measures: duration of effect should not be treated as the plasma elimination half-life. Exposure and calcium response require interpretation in the clinical context of vitamin-D treatment.

Ingredient-level summary of the cited reference product. Study formulation, route, strength and population govern interpretation; these data do not establish pharmacokinetics or bioequivalence for Walter's formulation or fixed combination.
