Vitamin A

Vitamin A is one of the few fat-soluble nutrients your body cannot synthesise in useful amounts on its own, yet it plays a central role in vision, immune function, and skin cell renewal.

Retinol, the active form found in animal-based foods, binds to receptors in cell nuclei and regulates gene expression across many tissue types. This is what makes it so influential for skin regeneration, mucous membrane integrity, and normal vision in low-light conditions. Vitamin A works closely with vitamin D vitamins in supporting immune defence, which explains why vitamin A and D supplement combinations remain popular in practice.

Research suggests adequate vitamin A status supports normal immune response, with deficiency linked to increased susceptibility to infection. Studies indicate it plays a role in maintaining the integrity of respiratory and digestive linings, your first line of defence against pathogens. Fat matters here. Vitamin A requires bile for proper absorption, so taking it alongside a meal containing dietary fat improves uptake considerably.

People eating low-fat diets, those with fat-malabsorption conditions, and anyone already taking vitamin D vitamins often assess their vitamin A levels at the same time, since both share similar absorption pathways. Skin health, eye health, and immune resilience are the most common reasons people reach for vitamin A supplementation.
