How to Take It
Best taken in the morning
Contains Caffeine, which is stimulating — keep it to the morning. Take it with a meal containing fat — the vitamin A in it absorbs poorly without one.
With a meal containing fat
On the label
Add it to foamed nut milk for a nutritious latte, sprinkle over your popcorn, or blend it in with your baking. Or you can do the really obvious thing and make yourself an incredible mug of Matcha tea and enjoy a warm, tasty nutrition boost!
General guidance based on the ingredients, not a substitute for the label or your doctor.
