Vitamin D3-d₃ is the deuterium labeled Vitamin D3. Vitamin D3 (Cholecalciferol; Colecalciferol) is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.

Vitamin D3-d₇ is the deuterium labeled Vitamin D3. Vitamin D3 (Cholecalciferol) is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.

Maxacalcitol-d₆6 is the deuterated form of Maxacalcitol (22-Oxacalcitriol), which is a non-calcemic vitamin D3 analog and VDR ligand of VDR-like receptors.

Paricalcitol-d₆ is the deuterium labeled Paricalcitol. Paricalcitol is a agent used for the prevention and treatment of secondary hyperparathyroidism (excessive secretion of parathyroid hormone) associated with chronic renal failure.

Calcifediol-d₃ is a deuterium labeled Calcifediol. Calcifediol, is an effective VDR ligand and VD supplement. Calcifediol is a prohormone of the vitamin D endocrine system (VDES) and is hydroxylated in the liver to produce the active form, calcitriol. Calcifediol can rapidly increase serum VD levels.

Eldecalcitol-d₆ is the deuterium labeled Eldecalcitol. Eldecalcitol is an orally active analogue of active vitamin D used in the treatment of osteoporosis.

Vitamin D2-d₃ (Ergocalciferol-d₃) is the deuterium labeled vitamin D2 (HY-76542), where the C-6 and C-19 protons are replaced by deuterium. Vitamin D2 (Ergocalciferol), drived from plant sources or dietary supplements, could be used as supplement of Vitamin D.

25-Hydroxy VD2-d₆ is the deuterium labeled 25-Hydroxy VD2.

Alfacalcidol-d₆ is the deuterium labeled Alfacalcidol. Alfacalcidol is a non-selective VDR activator.

Calcifediol-d₆ monohydrate is the deuterium labeled Calcifediol monohydrate. Calcifediol monohydrate (25-hydroxy Vitamin D3 monohydrate), is an effective VDR ligand and VD supplement. Calcifediol is a prohormone of the vitamin D endocrine system (VDES) and is hydroxylated in the liver to produce the active form, calcitriol. Calcifediol can rapidly increase serum VD levels.

Ercalcidiol-d₃ is the deuterium labeled Ercalcidiol. Ercalcidiol is a metabolite of Vitamins D2. Ercalcidiol can be used as an indicator of vitamins D status.

Vitamin D2-d₆ is the deuterium labeled Vitamin D2. Vitamin D2 (Ergocalciferol), drived from plant sources or dietary supplements, could be used as supplement of Vitamin D.

Vitamin D3-¹³C₅ is the ¹³C-labeled Vitamin D3 (HY-15398). Vitamin D3 (Cholecalciferol) is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.
