Vision & Immunity
What it does
Vitamin A is what lets your eyes adjust to low light, and it keeps the surfaces that line your eyes, lungs, and gut healthy, your first physical barrier against infection. It's also involved in normal skin cell turnover. Because it's fat-soluble and stored in the body, more is not always better; dosing matters.
The science
A crucial fat-soluble compound that maintains the integrity of the ocular system, supports vital organ function, and regulates cellular immune responses.
Most relevant for
Vision and skin support. Pregnant women should avoid high-dose retinol; check with your doctor.
