What Vitamin D Is
A fat-soluble vitamin that functions as both a vitamin and a hormone.
Exists mainly as D2 (ergocalciferol) from plant sources and D3 (cholecalciferol) from sunlight, animal foods, and supplements.
Activated in the body through conversion to calcidiol (25(OH)D) in the liver and calcitriol (1,25(OH)₂D) in the kidneys.
 
Bone and Musculoskeletal Health
Calcium absorption: Vitamin D is essential for intestinal absorption of calcium and phosphorus.
Bone strength: Prevents rickets in children and osteomalacia in adults. Supports bone density and reduces fracture risk in older adults.
Muscle function: Adequate vitamin D supports muscle performance and reduces risk of falls.
 
Immune System Function
Regulates both innate and adaptive immunity.
Deficiency is linked to higher risk of respiratory infections, autoimmune diseases, and chronic inflammation.
Supplementation has been shown to modestly reduce risk of acute respiratory infections in people with low baseline vitamin D levels.
 
Cardiovascular and Metabolic Effects
Low vitamin D is associated with hypertension, insulin resistance, and metabolic syndrome.
Evidence is mixed: supplementation may improve blood pressure and glucose control in deficient individuals, but benefits are less clear in people with sufficient levels.
 
Cancer Research
Observational studies suggest higher vitamin D status is associated with lower risk of colorectal cancer and possibly breast and prostate cancers.
Proposed mechanisms: regulation of cell growth, promotion of apoptosis, inhibition of angiogenesis, and reduction of chronic inflammation.
Large clinical trials have shown mixed results, with benefits mostly in those who are deficient rather than the general population.
 
Brain and Cognitive Health
Vitamin D receptors are present in brain tissue.
Deficiency has been associated with higher risk of depression, cognitive decline, and dementia.
Evidence for supplementation improving mood or cognition is still emerging and somewhat inconsistent.
 
Other Benefits
Autoimmune conditions: Low vitamin D is linked to increased risk of multiple sclerosis, type 1 diabetes, and rheumatoid arthritis.
Pregnancy: Adequate vitamin D supports fetal skeletal development and may reduce risk of preeclampsia and gestational diabetes. (Check dosage with Gynae before supplementing)
Longevity: Some data suggest low vitamin D is linked with higher all-cause mortality, though it’s unclear whether supplementation extends lifespan directly.
