Beta-carotene, a provitamin A from plants, must be converted to retinol – a process that declines with age, certain health conditions, and genetics. Retinol-based supplements provide a more predictable and immediate source of vitamin A activity. Superior Source uses retinyl palmitate, a stable ester of retinol, ensuring consistent potency and absorption.\u003c\/p\u003e\u003ch2\u003eHow Much Vitamin A Do You Need?\u003c\/h2\u003e\u003cp\u003eThe Recommended Dietary Allowance (RDA) for vitamin A is 900 mcg RAE (3,000 IU) for men and 700 mcg RAE (2,333 IU) for women. The 10,000 IU dose in each MicroLingual tablet exceeds the RDA, which may suit individuals with higher needs due to dietary restrictions, malabsorption, or increased oxidative stress. However, the Tolerable Upper Intake Level (UL) for preformed vitamin A is 10,000 IU (3,000 mcg RAE) per day for adults. Exceeding this amount consistently can lead to toxicity. Consult a health-care provider before supplementing, especially if pregnant, nursing, or taking other medications.\u003c\/p\u003e\u003ch2\u003ePotential Side Effects and Safety\u003c\/h2\u003e\u003cp\u003eVitamin A from foods is generally safe, but high doses from supplements can accumulate and cause toxicity. Symptoms of acute toxicity include nausea, dizziness, headaches, and blurred vision. Chronic excess may result in liver damage, bone pain, and birth defects. Do not exceed the recommended dose. This supplement is non-GMO, gluten-free, and free from additives, preservatives, and dyes. Because the sublingual tablet is absorbed efficiently, adhere to one tablet daily. Always read the label and follow directions for use.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs this supplement suitable for vegans?\u003c\/h3\u003e\u003cp\u003eNo, the vitamin A is from retinyl palmitate, typically sourced from animals. Vegans may prefer a beta-carotene-based supplement.\u003c\/p\u003e\u003ch3\u003eCan I take this with other supplements?\u003c\/h3\u003e\u003cp\u003eVitamin A works well with vitamins D, E, and K2. Avoid multiple supplements with high doses of preformed vitamin A to stay within the UL.\u003c\/p\u003e\u003ch3\u003eHow should I store these tablets?\u003c\/h3\u003e\u003cp\u003eStore in a cool, dry place away from sunlight. Keep the lid tightly closed to protect from moisture.\u003c\/p\u003e\u003ch2\u003eUnderstanding Vitamin A\u003c\/h2\u003e\u003cp\u003eVitamin A is a fat-soluble vitamin essential for vision, immune function, and skin and bone health. It comes in two forms: preformed vitamin A (retinol) from animals and provitamin A carotenoids (like beta-carotene) from plants. The body converts these into active forms for cellular processes. Superior Source Vitamin A provides 10,000 IU of vitamin A as retinyl palmitate, a highly bioavailable form the body can use immediately.\u003c\/p\u003e\u003cp style=\"font-size:0.8em;\"\u003eThis natural health product is not intended to diagnose, treat, , or prevent any disease.
