Vitamin A, better known as a retinoid, is essential to maintaining balanced thyroid hormone levels for a healthy metabolism, eye sight, and overall skin health. While we opt for a skin safe alternative for topical use, the ingestion of high quality vitamin A is crucial for hormone balance. We use two forms of Vitamin A in our BioEvolve Multivitamin for optimal benefits – Beta carotene (naturally found in foods like carrots) and Palmitate. A skincare ingredient hero, Vitamin A boosts collagen production to reduce the appearance of wrinkles, for firmer more youthful-looking skin.
