Why is Vitamin D separate from AG1?

Vitamin D is hard for the body to process from foods, and it is known to be more effective when delivered in an oil form with vitamin K2. Since we never compromise on quality, AG Vitamin D3+K2 is formulated separately from the AG1 powder to ensure that these high-quality vitamins are absorbed into your body. The dropper also allows you to modify the dose to suit your needs based on time of year and lifestyle.

FAQs

Two drops of AG Vitamin D3+K2 contains 100 mcg vitamin K ; 50mcg MK7 and 50 mcg MK4. Trans and cis forms of MK7 are included and both have been found to be bioactive in the body.*

The vitamin D3 comes from lanolin, which is a natural byproduct of sheep wool. Throughout a sheep’s lifetime, wool is constantly being sheared to help regulate their body temperature. Using wool as a source of vitamin D delivers cholecalciferol, an effective, bioactive form of vitamin D known to support immune and bone health.*

Vitamin D3 is best absorbed in liquid form, and works even better when consumed with vitamin K2. So, to ensure you’re getting nutrients in a more useful form, we offer AG D3+K2 liquid nutrient drops separately. It includes an easy-to-use dropper that allows for individualized dosages and flexibility to fit into any daily requirement.
