How to Take Vitamins in Conjunction With Diet Pills

When taking diet pills you may still feel lacking in some areas. You may become agitated, sleepy or just need an extra boost of energy. Vitamins may help put you back on track. Different types of vitamins are readily available at supermarkets, pharmacies and specialty stores. Carefully weigh your options before starting any vitamin supplementation while taking over-the-counter or prescription diet pills.

Step 1

Study the nutritional facts and content of your diet pills. Some diet pills may already contain high percentages of certain vitamins such as your B vitamins. Upping your dose of these vitamins with over the counter or prescription diet pills could cause serious side effects.

Step 2

Talk with your doctor about the diet pills you are taking and if possible, show him the nutritional facts. He can help you to find vitamins to take with your diet pills that can give you that added boost. Ask your doctor before you start to take any diet pill or vitamin combination to avoid any unpleasant drug interaction.

Step 3

Do not take your vitamin and diet pill at the same time. This could cause a sick feeling or inhibit the effects of each other. Side effects of doing so can include nausea, headache and a restless feeling with irritability.

Tips and Warnings

  • While most FDA approved diet pills contain certain vitamins, there are some you should avoid and some that are safe to take. Vitamin C can be taken in conjunction with diet pills; however, it is not advised to take vitamins A and E as they could lead to toxicity in the blood stream. Multivitamins are generally safe, although some diet pills may not work as well when taken with them. Do not exceed one multivitamin per day, as this could cause serious side effects.
  • According to the FDA, taking the diet medication Xenical can block the adsorption of Vitamins A, D, E and K. The FDA recommends taking these supplements with Xenical.
