What vitamins & supplements should not be taken together?

By July 31, 2023September 22nd, 2023No Comments

The world of dietary supplements is witnessing a meteoric rise, from collagen powder to probiotics. A staggering 57% of Americans over 20 years old take at least one dietary supplement, according to data from the 2017-2018 National Health and Nutrition Examination Survey. Popular choices include multivitamins, vitamin D, and omega-3 fatty acids.

While supplements can be beneficial, it’s crucial to be aware of potential interactions that can affect their absorption and efficacy.

Taking certain vitamins together can impact their absorption in the body, either improving bioavailability or worsening it. Moreover, some vitamins might interfere with medication effectiveness and intensify side effects.

Understanding interactions and proper timing is key. Each supplement has specific administration requirements outlined on its label. Consulting a healthcare provider for accurate dosing is vital. Knowing which vitamins should not be taken together can prevent undesirable outcomes.

What vitamins should not be taken together?

  1. Magnesium and Calcium: These minerals work in tandem, but excess calcium can hinder magnesium absorption. Maintaining the right balance is crucial. Seek guidance from a healthcare provider.
  2. Iron and Green Tea: The iron-rich foods or supplements should not be consumed alongside green tea due to the iron-binding compound in green tea, which reduces iron absorption.
  3. Vitamin C and B12: High doses of vitamin C can hinder vitamin B12 absorption. Ensure a two-hour gap between taking these vitamins.
  4. Fat-soluble and water-soluble vitamins: Water-soluble vitamins (such as vitamin C and B vitamins) are best taken without food, while fat-soluble vitamins (A, D, E, K) require healthy fats for absorption and can be taken with food.

On the flip side, some vitamin combinations can spark synergistic benefits that elevate your nutritional game to the next level.

Which vitamins should be taken together?

  1. Vitamin D, Vitamin K2, and other Fat-soluble Vitamins: Vitamin D and vitamin K2 collaborate for calcium absorption and bone health. These fat-soluble vitamins (A, D, E, K) can be taken together with meals containing healthy fats.
  2. Magnesium and Vitamin D3: These two vitamins synergistically enhance each other’s functions. Magnesium is essential for converting vitamin D into a usable form.
  3. Copper and Zinc: Maintaining a balance between these minerals is crucial. Taking a 2 mg copper supplement alongside zinc can prevent imbalances.
  4. Omega-3s and Vitamin E: Combining omega-3 fatty acids and vitamin E can promote heart health and insulin resistance.
  5. Iron and Vitamin C: Some evidence suggests pairing iron with vitamin C enhances iron absorption, though more research is needed.

Remember, if you’re unsure about interactions or dosages, consulting a healthcare provider before starting a new supplement regimen is crucial. Their personalized guidance ensures you make informed decisions regarding your health journey.
