How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
On the label
Mix one packet of delicious and nutritious Efficient C + Cranberry Benefits with 4 to 8 ounces of water. You can use more or less water to adjust flavor intensity.
General guidance based on the ingredients, not a substitute for the label or your doctor.
