8 Best Immune Support Supplements for Adults 2023

The immune system is essential in protecting your body against viruses, harmful substances, and abnormal cell growths that could make you ill. Without an immune system, we wouldn't be able to protect our bodies from harmful substances that enter from the outside or harmful changes that occur inside our bodies.

A variety of vitamins and minerals also referred to as "micronutrients," are necessary for a strong immune system.

The following micronutrients are important for immunological function: (Source)
- vitamin A
vitamin D
vitamin C
- vitamin E
- vitamin B6
- vitamin B12
- folate
- iron
- copper
- selenium

Ideally, a balanced diet should be able to give us enough of these important micronutrients, but for some people, this may be challenging. As a result, some people decide to take supplements, and here are the best immune support supplement for adults you can buy online today!

I have tried several immune boosting products. Some I liked, some not so much. This Immune Booster is easy to take, has no unpleasant flavor, and I feel like it is helping me to stay healthier. This virus outbreak that has the world in a tailspin is an excellent example of why we all need to build our immune systems. I've had chemo, after stage 3 cancer surgeries, and my immune system will always be compromised. With products like Immune Booster, I know I am doing what I need to do to protect myself.

I have weak immune system. When the kids get sick so do I and my immune system seemingly doesn’t want to fight anymore. This knocks mucus out and clears my sinus and cough within a day if I take 2 doses. Nothing else works for me anymore plus Tylenol is bad on liver. I highly recommend this over any cold medicine if you ever got sick. I have tried everything. I mean everything. This is it.

I’ve been taking this multivitamin for a year or two, and I don’t know if it’s psychological or physical, but when I stop taking them for a few days, it seems that I have less energy. They are well-priced and easy to swallow, with no aftertaste. I figure it can’t hurt to keep taking them daily! :)


a. Best Time To Take Multivitamins

Some vitamins, like water-soluble vitamins, can be absorbed on an empty stomach. However, multivitamins typically contain fat-soluble vitamins as well, which require dietary fat for absorption.

That’s why it’s often best to take your multivitamin with a meal or snack.

To make remembering to take your multivitamin easier, it may be helpful to take your vitamin with the same meal each day.

b. Can I Take Multivitamins Everyday?

Studies have shown that while taking a multivitamin daily can help some individuals meet their nutritional needs, in others it may lead to excessive intakes of nutrients.

For this reason, it’s important to carefully read supplement labels and identify any nutrients that you’re already consuming regularly, either through your diet or other supplements you may be taking.

Another important factor is the types of vitamins included in a product.

Water-soluble vitamins, like B vitamins and vitamin C, are easily excreted in the urine when consumed in excess. However, fat-soluble vitamins — vitamins A, D, E, and K — can build up in the body, potentially leading to toxicity.

It’s a good idea to check with a healthcare professional before beginning any new supplement, including a multivitamin. They may recommend a single-nutrient vitamin for you, rather than a multivitamin, to ensure you aren’t regularly consuming excessive amounts of nutrients.
