Chewable D3 10 mcg (400 IU)
21st Century Chewable D3 is a vitamin supplement providing 10mcg (400 IU) of Vitamin D3 per tablet. While Vitamin D3 is crucial for bone health and immune function, research often suggests higher daily intakes for optimal health benefits for many individuals. This product's 10mcg dose is noted as underdosed compared to common clinical recommendations for adults. With only 1 active ingredient and 100% label transparency, it received an N+ Score of 40, resulting in an 'F' grade, indicating a below-average formulation for comprehensive Vitamin D support. This product may suit individuals with minimal Vitamin D needs or those using it as a very low-dose complementary supplement, but it is unlikely to address significant deficiencies.
