How to Take It
Best taken in the morning
The Vitamin B2 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamins A and K in it absorb poorly without one.
With a meal containing fat
Keep it away from medication and mineral supplements
Space it a couple of hours from Iron
On the label
As a dietary supplement, add one scoop (4.5 grams) daily to 8 fl oz water, juice (apple, orange or tomato) or your favorite smoothie and mix or shake until smooth. For best results, liquid should be very cold. Mixes instantly without the use of a blender.
General guidance based on the ingredients, not a substitute for the label or your doctor.
