4. Vitamin C
Part of making sure that your sinus infection doesn’t get the best of you is boosting your immune system so that your body’s natural defenses can beat the infection; one of the ways in which you can do this through vitamin C. Most experts recommend that you take 1000 mg a day when you’re not trying to fight off infection and that you up that to 4000 mg a day when there is an infection present in the body.
Vitamin C can be found in various forms such as capsules, chewable, Gummies and liquid, and you can buy them anywhere that you would be able to buy normal OTC medicine. Vitamin C is probably the most effective and most popular immune system support that you can get over-the-counter, and it is definitely one of the best things that you can use to fight your sinus infection naturally.
