One supplement that's affected by how you take it is iron. That works for both iron supplements and iron from food. Washing down your iron tablet with a glass of orange juice will allow for maximum benefit from the supplement. Don't take your iron with milk or tea. The calcium and phosphorous in milk and tannic acid in tea can interfere with iron absorption.
Calcium supplements work best when taken with a meal.
Stomach acid makes the pills dissolve better, and stomach acid increases when you eat. Doctors at UT Southwestern say calcium citrate is the most readily absorbed calcium supplement. Because calcium affects iron absorption, it's best not to take calcium and iron supplements together.
