What is Vitamin A Palmitate?
Vitamin A refers to a group of compounds that exist as either carotenoids or retinoids. Carotenoids aren’t bioavailable, and the body has to convert food sources into retinoids before it can absorb the nutrient. Some individuals have a hard time with the process, including premature infants, individuals with cystic fibrosis, and women and infants who don’t consume enough nutritious food. In contrast, retinoids are highly bioavailable, and the body absorbs them easily.
Vitamin A palmitate, also known as retinyl palmitate, is a fat-soluble retinol (Vitamin A1) ester combined with palmitic acid. Vitamin A is an essential nutrient, meaning the body can’t synthesize it and relies on food sources to obtain it. Common food sources of vitamin A palmitate include animal livers, fish, eggs, and cheese. Synthetic vitamin A palmitate supports skin, eye, hair, and reproductive health. It’s also a potent antioxidant that supports the immune system.
Potential Vitamin A Benefits
Vitamin A For Skin + Vitamin A For Acne
Retinol is a popular skincare ingredient used to improve visible signs of aging and brighten sun-damaged skin. Many skin care products include retinyl palmitate for its superior stability. Retinyl palmitate converts into retinol and then into its active form retinoic acid once absorbed by the skin.
One study examined the effects of vitamin A palmitate on photoaged skin on the neck, chest, and extremities. After two weeks, participants saw improvements in fine lines, pigmentation, roughness, firmness, and uneven skin tone. They also noted that vitamin a palmitate improved crepey skin, scaling, and dryness. These effects continued to intensify over the course of 12 weeks. Vitamin A also supports skin health by stimulating collagen production, a protein that improves skin elasticity and the appearance of wrinkles.
Vitamin A palmitate may improve acne lesions and reduce breakouts by regulating skin oils. Retinoids have proven effective at combatting acne in multiple studies. Vitamin A palmitate also promotes wound healing and supports the skin’s immune defenses.
Vitamin A For Eyes
Vitamin A is essential for eye health. Retinal pigmented epithelial (RPE) cells comprise the pigmented part of the retina and nourish retinal visual cells. Retinoic acid is essential for these cells to function properly. It also helps maintain and protect the cornea. Vitamin A deficiencies can cause several eye health problems, including dry eyes due to a failure to produce tears and night blindness.
Vitamin A For Hair
Numerous factors contribute to healthy hair, including genetics, aging, hormones, and nutrition. Every cell in the body relies on vitamin A for growth, and hair is no exception. Hair is the second-fastest-growing tissue in the body, second only to bone marrow. Vitamin A promotes healthy hair by stimulating hair oils that moisturize the scalp. Without sufficient vitamin A, individuals may begin to experience hair loss.
Vitamin A + Zinc
Zinc deficiencies often coincide with vitamin A deficiencies, as the body uses zinc to transport vitamin A throughout the body.
Potential Vitamin A Immune System Benefits
Vitamin A deficiency (VAD) is a known contributor to compromised immune function. Countries with widespread VAD noted a reduction in several health issues following vitamin A public health programs. In addition to lowering immune defenses, VAD can cause immune systems to overreact, leading to long-term inflammation, autoimmune problems, and more severe allergic reactions. Vitamin A supports immune function by triggering receptors in the bone marrow to produce new white blood cells. The immune system relies on white blood cells to protect the body against foreign invaders and infection. Vitamin A also directs the movement of T cells, one of the most important white blood cells involved in the adaptive immune response.
Vitamin A Muscle Growth
Vitamin A may enhance muscle growth. It plays an important role in protein synthesis, which is crucial for growing and maintaining lean muscle. Without sufficient vitamin A, the body begins to catabolize proteins instead of fatty acids for energy. Vitamin A also plays a role in regulating testosterone and other sex hormones. Inadequate vitamin A levels have an adverse effect on testosterone secretion. Vitamin A supports the structure and strength of extracellular matrix proteins that house muscle fibers.
Potential Vitamin A Side Effects
Vitamin A palmitate is fat-soluble, meaning the body stores it in fat tissues. Taking too much vitamin A can cause a toxic buildup and adverse health effects. People with liver disease, certain eye diseases, and pregnant individuals shouldn’t take vitamin A supplements. Vitamin A supplements may interact with certain medications, particularly those processed through the liver. Consult with a physician before taking any new supplement.
