Dr. Feb's Analysis
Scientific Mechanism
Vitamin D3 (cholecalciferol) is the bioactive form of Vitamin D. Upon ingestion, it undergoes hydroxylation in the liver and kidneys to become calcitriol. This active hormone binds to Vitamin D Receptors (VDR) in the small intestine and bone tissue. This binding facilitates the transcription of genes responsible for calcium-binding proteins, significantly enhancing the intestinal absorption of dietary calcium and phosphorus. By maintaining adequate serum calcium levels, it supports the mineralization of the organic bone matrix (osteoid), ensuring skeletal integrity and preventing demineralization.
Key Benefits
Key benefits include:
- Supports calcium absorption for bone strength
- Contributes to normal immune system function
- Helps maintain normal muscle function
- Promotes healthy mood and cognitive performance
Usage & Safety
The standard dosage is 1 gummy daily, or as directed by a healthcare provider. For optimal absorption, take with a meal containing healthy fats, as Vitamin D is fat-soluble. Do not exceed the recommended dose. Consult a physician if you are taking medications (especially thiazides or cardiac glycosides), have hyperparathyroidism, or kidney disease. Keep out of reach of children.
