Health Benefits
Facilitates intestinal uptake of calcium by interacting with vitamin D receptors, contributing to optimal calcium homeostasis.
Assists in mineral deposition and density maintenance, supporting the structural integrity of bones and teeth.
May modulate innate and adaptive immune responses through VDR-mediated pathways, enhancing immune surveillance.
Potentially supports neurotransmitter balance and mental clarity through shared neuroregulatory functions with other D vitamers.
Early studies suggest antiproliferative activity in hormone-sensitive cells, indicating potential for cellular health.
Origin & History
Vitamin D5 (Sitocalciferol) is a synthetic analog of the vitamin D family, structurally derived from 7-dehydrositosterol, a plant-based compound. While not naturally occurring in the human body or common food sources, preliminary research indicates its potential for enhancing calcium metabolism, supporting skeletal health, and exhibiting anticancer properties via vitamin D receptor (VDR) pathways.
“Modern biochemical compound without traditional medicinal history. Sitocalciferol is a product of contemporary pharmaceutical research, developed as a synthetic analog to explore novel therapeutic applications within the vitamin D family, particularly for its unique interactions with vitamin D receptors.”Traditional Medicine
Scientific Research
Preliminary research, primarily in vitro and animal studies, indexed on NIH PubMed and the National Library of Medicine, indicates Sitocalciferol's potential in calcium regulation and immune modulation. Further investigation is ongoing to fully understand its efficacy and safety as a vitamin D analog, particularly concerning its anticancer potential.
Preparation & Dosage
General
Primarily a research compound; not widely available as a commercial dietary supplement.
General
Under investigation for inclusion in bone health formulas, potentially combined with magnesium (Magnesium glycinate), Vitamin K2 (Menaquinone), and Vitamin D3 (Cholecalciferol).
General
Explored in cellular defense research for synergistic effects with polyphenols or selenium in chemopreventive models.
General
Dosage and specific applications are currently experimental and not established for general public use.

Frequently Asked Questions
What is Vitamin D5 (Sitocalciferol)?
Vitamin D5 is a synthetic analog of the vitamin D family derived from 7-dehydrositosterol, a plant sterol compound. It is not naturally produced in the human body and is not found in common foods. It is currently a research compound being investigated for potential roles in calcium metabolism and anticancer activity.
Can I take Vitamin D5 as a supplement?
No. Vitamin D5 is not commercially available as a dietary supplement and has no established safe dosage for human use. It remains in the preclinical research phase. For vitamin D supplementation, cholecalciferol (D3) is the recommended and well-studied form.
How does Vitamin D5 differ from Vitamin D3?
Vitamin D3 (cholecalciferol) is the naturally occurring, well-researched form with extensive clinical evidence supporting its safety and efficacy. Vitamin D5 is a synthetic analog with preliminary research suggesting lower VDR binding affinity and limited human data. D3 remains the gold standard for supplementation.
