There are certain vitamins and supplements that should not be taken together, as they can interfere with the absorption or effectiveness of each other. Here are a few examples:

  1. Calcium and iron: Calcium can interfere with the absorption of iron, and vice versa. If you are taking supplements that contain both of these nutrients, it's important to take them at least two hours apart to ensure optimal absorption.

  2. Vitamin E and blood thinners: Vitamin E can interfere with the effectiveness of blood thinners such as warfarin (Coumadin). If you are taking a blood thinner, it's important to speak with a healthcare professional before adding a vitamin E supplement to your routine.

  3. Vitamin K and blood thinners: Like vitamin E, vitamin K can also interfere with the effectiveness of blood thinners. If you are taking a blood thinner, it's important to speak with a healthcare professional before adding a vitamin K supplement to your routine.

  4. Vitamin D and calcium: Vitamin D is necessary for the proper absorption of calcium, so it's generally recommended to take these two nutrients together. However, if you are taking high doses of calcium, it's possible to develop an excess of vitamin D, which can lead to toxic levels. It's important to speak with a healthcare professional if you are taking high doses of calcium or are considering adding a vitamin D supplement to your routine.

  5. St. John's wort and antidepressants: St. John's wort is an herb that is sometimes used to treat depression, but it can interfere with the effectiveness of certain antidepressants. If you are taking an antidepressant, it's important to speak with a healthcare professional before adding St. John's wort to your routine.

It's worth noting that this is not an exhaustive list, and there may be other vitamins and supplements that should not be taken together. If you are taking multiple supplements or are considering adding a new supplement to your routine, it's important to speak with a healthcare professional to ensure that it is safe and appropriate for you.
