How to Take It
Best taken in the morning
The Iron in it is what pulls this toward the morning. Vitamin B6 is easier on the stomach taken with food.
With food
Iron does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
On the label
Take 1 capsule one to three times daily or as recommended by a health-care practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.

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.
