Overview
A combination mineral supplement from Amazing Formulas providing calcium, magnesium, zinc and vitamin D3 in tablet form, 300 tablets per bottle with a listed serving size of 3 tablets.
Per the 3-tablet serving, the formula provides 1000mg calcium, 400mg magnesium, 25mg zinc and 600 IU vitamin D3, a combination often taken together since vitamin D3 supports calcium absorption while magnesium and zinc are commonly paired with calcium. At 300 tablets and a 3-tablet serving, one bottle covers 100 servings.
- 1000mg calcium, 400mg magnesium, 25mg zinc, 600 IU D3 per 3-tablet serving
- 300 tablets per bottle
- 100 servings per bottle
- Dietary supplement tablet form
Who it's for
Suits buyers wanting a single tablet product covering calcium, magnesium, zinc and D3 rather than four separate bottles. Not ideal for anyone who needs to adjust the ratio between these minerals individually, since they are fixed in one formula.
