The evidence shows that this product contains vitamin D3, but the specific dosage is not listed on the label. Vitamin D is essential for bone health and immune function, but without a known dose, we cannot confirm if this product meets the Recommended Dietary Allowance of 600 IU for most adults [NIH ODS].
How it works
Vitamin D3 acts as a master regulator in your body. It supports calcium absorption for strong bones and helps your immune system respond appropriately to threats. Think of it as a key that unlocks your body’s ability to use calcium and maintain healthy cell function [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports for dietary supplements overall. For vitamin D specifically, high levels can cause poor muscle tone, nausea, and abnormal heart rhythms [NIH ODS].
