How to Take It
Best taken in the morning
Contains Green Tea Leaf Extract, which is stimulating — keep it to the morning. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
Keep it away from iron-rich meals
Space it a couple of hours from Iron and Calcium

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.
The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
