Description
"Vitamin A" is a fat-soluble supplement available as retinol (from animal sources) or beta-carotene (from plants), contributing to various biological functions. It is essential for eye health, particularly in low-light vision. This vitamin supports immune resilience by assisting natural defense mechanisms. Its antioxidant properties help maintain cellular integrity and tissue health. Vitamin A also plays a role in skin maintenance and epithelial function. Sourced from diet and supplementation, it remains a fundamental part of balanced nutrition.

When To Take It
Vitamin A is best taken with meals that contain fat for optimal absorption. If taken in oil form, it can be consumed at any time of day.
Synergy and Antagonism

However, it may have antagonistic interactions with vitamin D, calcium, copper, sodium, selenium, and iron, as excessive amounts can interfere with its absorption or function.
