The 5 best vitamins for a strong immune system

The 5 best vitamins for a strong immune system


It’s no fun to be sick, and even worse when you feel like it’s holding you back from spending time with loved ones or getting your work done. Vitamins enrich our bodies in numerous ways, from growth to cognitive function, but one of their most appreciated assets is their ability to help with our immunity.

This is why we want to share the best five vitamins for supporting our immune systems. Each one offers its own unique form of support to our white blood cells or by delivering other preventative measures in our bodies.

Keeping our cells, tissues, and blood vibrant and healthy is no small undertaking and a healthy diet is one of the best ways to improve immunity. If you don’t feel your eating habits will guarantee you vitamins and minerals from whole, fresh foods, you can take supplements like our Healthy Human Immunity Hydration Tablet during your daily routine.

Vitamin D

Vitamin D is one of the most important vitamins for immunity, because studies suggest that it prevents respiratory diseases and it can even help prevent extreme infections from the Covid-19 virus. Vitamin D supports our white blood cells by limiting them from causing inflammation, while it also boosts their production of the proteins that respond to microbes.

Unlike other Vitamins, which we mostly get through food, our bodies absorb Vitamin C when we spend time in the sun’s rays. Other sources of Vitamin D include fish like salmon, tuna, and swordfish as well as egg yolks.

Our contemporary lives, which are predominantly spent indoors, make Vitamin D deficiency common. People with darker skin may also lack vitamin D in their bodies, since their melanin blocks some of the skin’s ability to absorb the vitamin. Since the sun can also damage our skin, people often protect themselves from the sun with sunscreen. This can also prevent the absorption of Vitamin D. In short, our bodies often need Vitamin D supplementation to improve our wellbeing.

Vitamin A

Carrots are known to contain high amounts of vitamin A, and they’re often associated with eye health. Another important feature of vitamin A is its ability to directly support our immune systems. It helps our bodies produce more white blood cells and spur them into action. This makes it important for immunity, because our white blood cells are the real guardians of our immune system health.

Vitamin A specifically helps prevent gut or intestinal infections, because it helps the intestinal immune response. It can lower the likelihood of diarrhea, and death in malnourished or HIV-infected children. This is why its claim to fame should extend beyond vision to gut health and anti-inflammatory properties.

Color is an excellent indicator of vitamin A content. Search for vegetables that have a dark green color (leafy greens), an orange color (carrots, acorn squash or sweet potatoes and pumpkin) or yellow-colored squash (summer squash).

Vitamin A has two different forms in supplements: beta-carotene and preformed vitamin A. High levels of preformed vitamin A can lead to a toxic response, and the beta-carotene version is generally safer, as it is not toxic at high levels.

Vitamin C

We associate the zesty citrus of fruit juices like orange juice, lemonade, and grapefruit juice with the healing properties of Vitamin C. These and other natural sources of Vitamin C like peppers and leafy greens, heal our bodies with the antioxidant powers of the water soluble vitamin.

Vitamin C, commonly referred to as ascorbic acid, was first identified by Hungarian researcher Albert Szent-Györgyi in 1928, who devised a way to isolate it from the paprika plant. He later won a Nobel Prize for his research on its metabolic role in cells.

However, the consequences of failing to consume enough Vitamin C were well known from sailors and passengers who crossed the oceans on ships. Their diets, poor in fresh fruits and vegetables, specifically lacked Vitamin C, which led to scurvy. It weakened their gums, which swelled and bled, and their wounds could not heal easily.

This gives some insight into the way that Vitamin C helps our bodies. It wards off the damaging effects of free radicals, which degrade our tissues, by binding to them and neutralizing them. This helps our bones, teeth, gums, internal organs, collagen, and blood vessels all grow and remain strong.

Contrary to popular belief, there is no evidence that Vitamin C wards off colds or the flu. This notion was popularized by Linus Pauling, a two-time Nobel Prize winning genetic researcher who became fascinated with Vitamin C and recommended it for various healing properties in the 1970s. Instead, it gives the immune system support rather than a direct boost. Nevertheless, Dr. Fauci recommended taking Vitamin C along with Vitamin D as safe ways to improve our health during the Covid-19 pandemic.

Vitamin B6

Vitamin B6, a water soluble vitamin, plays many roles throughout the body from cognitive development to metabolic functions. It helps lymphocytes, which are the white blood cells in our lymph nodes and bone marrow, mature and differentiate. Its immune support function is mostly at the cellular level, so it can help fight bacteria, viruses, and even cancer.

Popular vitamin B6 food sources include chickpeas, potatoes, bananas, fish, poultry, and beef liver. Many people also supplement their diets by taking the vitamin as pyridoxine or PLP. It is a safe vitamin to take in supplement form, since any excess usually is eliminated from the body through urine.

Vitamin B6 deficiency usually only occurs in concert with a lack of other b-complex vitamins. So if you’re running low on B6, you’re probably running low on other B-vitamins as well.

Vitamin E

Vitamin E is another important antioxidant like Vitamin C, but it is fat soluble. This means it eliminates free radicals which enter our body from the environment or appear after metabolic functions. In terms of immunity, this vitamin helps white blood cells function properly. In addition to fighting bacterial infections and viruses, it can also prevent cancer and heart disease.

Vitamin E is mostly found in nuts like almonds, hazelnuts, and peanuts as well as sunflower seeds. You can also take it as a supplement, though vitamin E deficiency is uncommon for people with healthy diets.
