Buying guide for best immune boosting multivitamins

No matter what type of lifestyle you have, multivitamins provide a simple solution to help fill nutritional gaps and give your immune system support.

When presented with the many multivitamins available, however, finding your perfect match can be downright confusing and perhaps frustrating. If you'd like to boost your immune system but have no idea where to start, we're here to help.

Many people have a hard time obtaining optimal levels of vitamins and minerals from their diets alone. Multivitamins offer a convenient way of bridging potential nutritional gaps.
"Not all vitamins provide a complete dose in a single pill, and some may need to be taken several times a day. If you prefer the convenience of a “one-a-day” vitamin, double-check the dosage instructions before buying."

Who needs immune boosting multivitamins, anyway?

It's possible that your body is running at full strength with no maintenance required. If you eat a varied and balanced diet, you may already be receiving all the nutrients, vitamins, and minerals your body needs, and ultimately, healthy foods are the best source of vitamins.

However, many people may lack one or more of the vitamins critical to proper immune health. Sometimes this is due to an insufficient diet and sometimes genetics are to blame, but whatever the cause, vitamin deficiencies are very common. 

According to a number of dietitians and nutritionists, the vitamins that play the most important role in order to keep your immune system running in top gear are vitamins A, B6, C, D, E, and Zinc:

  • Vitamin A: Has an antioxidant effect to help strengthen the immune system against infection. 

  • Vitamin B6: Is integral to overall immune system function as it's related to nearly 200 biochemical reactions in the body.

  • Vitamin C: Plays a particularly vital role in immune system function, although it's found in so many fruits and vegetables, deficiencies are considered uncommon. 

  • Vitamin D. A crucial vitamin to the immune system, but unfortunately, deficiencies are very common, particularly if you're not directly in the sun (it's absorbed directly from sunlight).

  • Vitamin E: Like vitamin C, vitamin E can be a powerful antioxidant to help the body fight off infection.

  • Zinc: Known to help slow immune response and control inflammation in the body. 

At the end of the day, there are countless reasons you might need to take an immune boosting multivitamin.
