Vitamin A is not just for eyesight, it’s a multi-system nutrient. In its active form (retinol), Vitamin A turns on hundreds of genes that regulate immune function, cell growth, hormone signaling, and tissue repair. The carotenoid family (beta-carotene, alpha-carotene, lutein, zeaxanthin) also brings antioxidant and tissue-protective effects that complement retinol.

When we include Vitamin A (as Retinol Palmitate) and mixed carotenoids in CODE Complex^®, we’re aiming for a balanced, bioavailable form that your body can put to work immediately while still giving your system the precursors it can safely convert as needed. (NIH)

Vitamin A Supports Across Your Body’s Systems

Why Personalized Vitamin A Matters

The right amount and form of vitamin A should match your unique genetic blueprint. Everyone metabolizes and uses nutrients differently, and variants in BCO1 (formerly BCMO1) affect the key enzyme that converts beta-carotene into retinol can dramatically affect how much active vitamin A your body produces. Two people with the same blood level of vitamin A can experience very different outcomes depending on how efficiently their genes convert carotenoids to retinol.

In CODE Complex^®, we combine preformed retinol with mixed carotenoids to give you readily usable vitamin A while also supporting your body’s natural conversion pathways. At SNiP Nutrigenomics we test BCO1 so you can understand your personal ability to convert carotenoids to retinol. While we don’t formulate CODE Complex^® directly from your BCO1 result, but we do use the most bioavailable blend of retinol palmitate and carotenoids to accommodate common variants and ensure your body gets vitamin A it can truly use.

Vitamin A–Rich Foods You Can Add to Your Diet

Active Retinol (Animal Sources):

Carotenoids (Plant Sources):

Tip: Pair carotenoid-rich veggies with healthy fat (like olive oil, avocado, or nuts) to enhance absorption.
