Active Calcium Chewable
USANA Active Calcium Chewable is a bone health supplement formulated with three active ingredients. Each two-tablet serving provides 400mg of Calcium and 200mg of Magnesium, both of which are present at clinically relevant dosages that research suggests may support bone density and muscle function. However, the product contains 200 IU of Vitamin D3, which is underdosed compared to amounts commonly studied for optimal calcium absorption. With an N+ Score of 58 and a grade of F, this product falls into the average tier, indicating areas for improvement in its formulation despite its 100% label transparency. This supplement may be suitable for individuals seeking foundational calcium and magnesium support, though additional Vitamin D supplementation might be considered.
