Vitamin D and autoimmune diseases; a deficiency disrupts the foundation of our immune systems

 Vitamin D deficiency disrupts thymus function and immune tolerance, triggering autoimmune diseases by allowing self-reactive T cells to escape into the bloodstream.

Vitamin D enhances both innate and adaptive immunity by boosting antimicrobial peptides, suppressing inflammatory responses and promoting regulatory T cells that maintain immune balance.

Beyond immune function, vitamin D supports muscle health, helps prevent neurodegenerative conditions and plays a role in metabolic processes and insulin sensitivity.

Sunlight is the optimal source of vitamin D, but exposure should be carefully managed, especially for those consuming seed oils, which oxidise under UV light.

Regular vitamin D testing is recommended, with optimal levels between 60 to 80 ng/ml. Supplementation may be necessary when sunlight exposure is insufficient....<<<Read More>>>...
