Thorne Research, Vitamin A 90 vegetarian capsules

Vitamin A deficiency is a common occurrence and may be associated with a number of disease processes. Such deficiencies can be the result of poor food choices and depletion of vitamin A from processed foods. Vitamin A is vital for eye health, particularly for night vision and prevention of cataracts and macular degeneration. Vitamin A is also an essential nutrient for maintaining healthy skin, especially in management of acne and prevention of wrinkles. In addition, vitamin A plays a critical role in supporting healthy bone growth and promotion of normal cellular differentiation and growth.

Vitamin A is essential for a healthy immune system – necessary for a healthy GI mucosal barrier to infection and normal function of neutrophils, macrophages, and natural killer cells. A deficiency is associated with a poor antibody response to infection. Vitamin A deficiency is a common occurrence in HIV infection, with low serum levels found in 12-19 percent of HIV-positive, asymptomatic individuals in the United States; serum levels appear to decrease as the disease progresses. Vitamin A deficiency  in pregnant, HIV-positive women has also been associated with increasedtransmission of HIV to the fetus.

As with our other single vitamin offerings, Thorne Research Vitamin A is free of any hidden preservatives or allergenic substances, for better tolerance even among the most sensitive patients.
