Nature's Sunshine Vitamin A & D
Brand: Nature's Sunshine · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that the combination of vitamin A and D in Nature's Sunshine Vitamin A & D is a common pairing, but the specific benefit depends entirely on your individual needs. Data for the ingredients is available only for calcium, not for vitamin A or D directly [NIH ODS]. Because of this, we cannot assess the specific efficacy of this product based on the provided data. We recommend consulting a healthcare provider to determine if you have a deficiency in either vitamin A or D before taking this supplement.
How it works
While no specific mechanism is provided for vitamin A or D in this product, the data for calcium, a related mineral, shows it supports bone mineralization and neuromuscular relaxation [NIH ODS]. This means calcium helps build bone density and supports normal muscle and nerve function. Without ingredient-specific data for vitamin A and D, we cannot describe their mechanisms for this supplement.
Safety profile
Data not available for specific side effects of Nature's Sunshine Vitamin A & D. The FDA has received a total of 592,059 adverse event reports across all supplements, but no report count is provided for this specific product [FDA data]. For calcium, high intakes might increase the risk of heart disease and prostate cancer, and can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. However, these effects are for calcium, not for vitamin A or D in this product.
Our recommendation
Our assessment: Do not start this supplement without first having your blood levels of vitamin A and vitamin D checked. Because specific data for this product's ingredients is missing, we cannot confirm its safety or effectiveness for you. Talk to your doctor or a clinical pharmacist to determine if this combination is appropriate based on your lab results and health history [NIH ODS] [FDA data].
