A daily multivitamin covering 26 vitamins and minerals, mostly at RDA levels. The bright spot is **Vitamin D3** at 1,000 IU — right at the minimum clinical dose for maintaining adequate blood levels, and in the preferred cholecalciferol form. Beyond that, most nutrients sit at basic daily value amounts, which means you're covered for preventing outright deficiency but not reaching the higher ranges used in clinical research for specific health goals.
Nearly every mineral uses a budget form: **Magnesium** as oxide (roughly 4% absorption), **Zinc** as oxide, **Selenium** as sodium selenate, and **Copper** as sulfate. The B vitamins follow the same pattern — **B12** as cyanocobalamin, **Folate** as synthetic folic acid, and **Vitamin E** in the synthetic dl-alpha form, which your body uses about half as efficiently as the natural version. You do get several built-in synergies (Vitamin C with iron, D3 with calcium, B12 with folate), but the doses are modest enough that the practical benefit is limited.
The biggest gap is **Magnesium** at just 50 mg — about 25% of the RDA — in the least absorbable form available. If you're looking for meaningful magnesium support, you'd need a separate supplement alongside this one.
