There are many types of natural and herbal supplements that help the body fight disease. Dietary supplements contain a concentrated form of different types of nutrients and are aimed at increasing the level of nutrients that the body absorbs. They can contain vitamins, minerals, herbal supplements, amino acids and enzymes.
How the immune system works
Vitamins and minerals
Four vitamins that are important when it comes to supporting the immune system are Vitamin C, Vitamin D, Vitamin E and the Vitamin B complex.
I believe a lack of vitamin C in the diet to make a person more susceptible to disease. Vitamin C is a powerful antioxidant, but there isn’t enough clinical research to show that vitamin C can boost the immune system in preventing conditions like the common cold, according to Oregon State University. However, the study found that during extremely stressful situations (such as for those running a marathon), vitamin C supplementation resulted in a lower incidence of upper respiratory tract infections. 2
Unless a doctor who is knowledgeable about the safe use of herbs and supplements gives a recommendation (such as when someone is vitamin C deficient), it may be better to get your daily vitamin C levels from food sources such as kiwi and citrus . , strawberries, red peppers and more
Benefits of Vitamin C.
Note: When taking vitamin C supplements, it is best to dispense it throughout the day, rather than taking the entire daily dose in one sitting.
Studies in humans have found that vitamin B6 levels affect the immune response.4 In fact, the body needs B vitamins to make immune cells. There are several members of the vitamin B complex needed to promote disease prevention by boosting the immune system, including pyroxidine (B6), thiamine (B1), riboflavin (B2), and more. These B vitamins are essential for maintaining a healthy immune system. 5
Food should be the major source of B vitamins, but several factors can lead to vitamin B deficiency; these include not having a varied diet (including food sources rich in B vitamins), taking certain medications, and more. Unless someone is vitamin B deficient, supplements may not be necessary.6 Foods such as green vegetables, beef liver, tuna, salmon, fortified cereals, onion, chicken and cold water sources of fish and chickpeas are great sources of vitamin B6.
Benefits of Vitamin B6
I associate vitamin D deficiency with an increased susceptibility to infections. In fact, a 2012 study looked at multiple studies that reported lower it linked vitamin D levels to an increase in infection (such as respiratory tract infections). 7
A double-blind placebo study (the gold standard of medical studies) found that a therapeutic dose of vitamin D resulted in a 42% lower incidence of influenza infections. 7
According to a 2013 study published by the journal DermatoEndocrinol, vitamin D deficiency should be addressed by:
Eating foods that naturally contain vitamin D (such as vitamin D-fortified dairy products, fatty fish [such as tuna and salmon], egg yolks, and beef liver)
Get sensible sun exposure (sunlight promotes vitamin D synthesis in the body).
Taking vitamin D supplements. 8
As with other vitamin supplements, caution is advised before taking vitamin D. When taken in high doses, vitamin D can increase calcium levels in the blood. This increase in calcium can be dangerous and cause serious side effects. Also, many medications can interfere with vitamin D and calcium levels. Vitamin D should only be taken if approved by a health care professional.
Note, make sure to consult a healthcare provider who is knowledgeable about natural supplements before taking vitamin D (especially for those with a medical condition.
