Vitamin A is an indispensable nutrient, essential for a wide array of bodily functions, from vision to immune defense. While obtaining Vitamin A from a balanced diet is ideal, supplementation can be beneficial for certain individuals. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes a science-backed approach to Vitamin A, ensuring both efficacy and safety in its products.

The recommended daily allowance (RDA) for Vitamin A varies by age, sex, and life stage. For adults, typical recommendations range from 700-900 micrograms of retinol activity equivalents (RAE) per day. It's crucial to adhere to these guidelines, as Vitamin A is fat-soluble, meaning the body stores excess amounts, which can potentially lead to toxicity if intake is consistently too high. Symptoms of excessive Vitamin A can include blurred vision, dizziness, nausea, and in severe cases, liver damage or bone abnormalities.

Sources of Vitamin A significantly influence the risk of toxicity. Preformed Vitamin A (retinol), found in animal products and supplements, is more readily converted to active forms and poses a higher risk of toxicity with excessive intake. Provitamin A carotenoids, like beta-carotene from fruits and vegetables, are generally considered safer as the body regulates their conversion to retinol. However, very high, prolonged intake of beta-carotene supplements can lead to carotenemia, a harmless orange discoloration of the skin.
