Our assessment
The evidence shows that this product contains 25,000 IU of Vitamin A, which is a very high dose. Data for the specific ingredient calcium, which is not in this product, is provided, but for Vitamin A specifically, high-dose supplementation requires careful consideration. You should be aware that the data provided does not include specific Vitamin A studies or side effect reports for this exact product; therefore, a general assessment based on available data is limited. Data not available for Vitamin A-specific studies from the provided list.
How it works
Vitamin A is a fat-soluble vitamin that plays a critical role in vision, immune function, and cell growth. For the ingredient calcium, which is not in this product, the mechanism involves bone mineralization and neuromuscular relaxation [NIH ODS]. For Vitamin A, specific mechanism details are not provided in the data.
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this Vitamin A product are not available. For the unrelated ingredient calcium, high levels can cause poor muscle tone, poor kidney function, constipation, nausea, and abnormal heart rhythms [NIH ODS]. Data not available for side effects of this specific Vitamin A product from the FDA data provided.
Our recommendation
Because the data provided does not include safety studies or adverse event reports for this specific 25,000 IU Vitamin A product, you should consult with your healthcare provider before taking this high-dose supplement. The recommended dietary allowance for Vitamin A is much lower, and taking 25,000 IU daily without medical supervision may pose risks. Data not available to support a specific dose recommendation for this product.
