Vitamin World Vitamin A 10,000 IU
Brand: Vitamin World · Form: SOFTGEL CAPSULE [E0161]
Our assessment
Our assessment: Vitamin A at 10,000 IU is a high-dose supplement that exceeds the Tolerable Upper Intake Level (UL) for adults, which is 3,000 mcg (10,000 IU) of preformed vitamin A. For most people, a standard multivitamin provides sufficient vitamin A, and taking this high dose long-term may pose risks. Data on the specific benefits of this product is not available.
How it works
Vitamin A is a fat-soluble vitamin essential for vision, immune function, and cell growth. As a preformed vitamin A (retinol), it is directly used by the body. The recommended dietary allowance (RDA) for adult men is 900 mcg RAE (3,000 IU) and for adult women is 700 mcg RAE (2,333 IU) [NIH ODS]. This product provides more than three times the RDA for men and over four times the RDA for women in a single dose.
Safety profile
Data on side effects for this specific product is not available. However, taking high doses of preformed vitamin A (10,000 IU or more) daily over time can lead to toxicity, including liver damage, bone thinning, and birth defects. The FDA has received adverse event reports for vitamin A products, though specific report counts for this exact product are not available [FDA data]. Chronic intake above the UL should be avoided, especially during pregnancy.
Our recommendation
For most adults, we recommend a standard multivitamin or a lower-dose vitamin A supplement (e.g., 3,000 IU or less) to meet the RDA without exceeding the UL. This 10,000 IU product is only appropriate if you have a diagnosed deficiency under medical supervision. Do not take this dose if you are pregnant or planning to become pregnant. Consult your healthcare provider before starting this supplement [NIH ODS].
