Why are there synthetic vitamin sources for some of the ingredients in your blends?Updated a year ago

We use natural sources wherever we can - there are two instances where this can be an issue.

1. Volume, where natural sources of some vitamins require so much 'bulk' we can not always accommodate them within our serving size.
2. In some instances, there simply isn't a wholefood-led source of the beneficial vitamin.

However, we always ensure we complement any synthetic ingredient with a wholefood boost in our formulation.
