The immune system in the body works day-in and day-out to fight harmful germs you come across. Many factors shape the immune response, including age, genetics, health, and stress levels. One of the biggest contributors to boost the immunity system is your diet. Here are some of those that can strengthen and support immunity: 

Vitamins to Boost Immune System Quickly

Vitamin C is an important nutrient that can prevent infections or, in the worst case, get rid of them quickly. One of the best sources of this is citrus fruits, but if you are looking for other options, it includes:

• Bell peppers
• Spinach
• Kale
• Brussels sprouts
• Papaya
• Strawberries

To name a few. The good news is that it is present in many food items that you don’t need any supplements, but the above foods, along with oranges, tangerines, and grapefruits, can act as an immune system booster. 

B Vitamins

B Vitamin family nutrients are essential as they aid in producing cells for the immune system. The deficiencies of these Vitamins can compromise the functioning of the immune system. B6 and B12 among the B Vitamin family are crucial as they support the body's various biochemical reactions. Foods that are rich in B Vitamins are:

• Fish
• Poultry
• Peanuts
• Peas, chickpeas, and kidney beans
• Soya beans
• Oats
• Banana
• Broccoli
• Brussel sprouts
• Leafy vegetables

If you are looking at how can i boost my immune system in 24 hours? Then up your intake of B Vitamins and Vitamin C and see it ward off infections quickly. 

Vitamin E

Many people know Vitamin E is good for the hair and skin. But did you know that it is a nutrient that can fight infections due to the presence of powerful antioxidants? It is an important Vitamin as it is helpful in many of the functions of the immune system and can also boost the immune system quickly. Wondering how to get this apart from finding supplements? It is present in high-fat plant foods, like: 

• Peanuts
• Sunflower seeds
• Almonds
• Hazelnuts
• Oils like soybean oil, sunflower, and safflower 

Vitamin D

The sunshine Vitamin is one of the powerful nutrients that is crucial for the body as it supports immunity. Deficiency of this nutrient can lead to autoimmune disorders like rheumatoid arthritis, psoriasis, and multiple sclerosis. This micronutrient helps in multiplying the WBCs and strengthening the defenses against infections. Vitamin D is available in limited food sources, which include:

• Sardines
• Vitamin D fortified milk, cereals, orange juice
• Mackerel
• Salmon
• Tuna

While it is best to get it from food, you may need a supplement as Vitamin D is available in limited foods. Learn how to test immune system strength at home and act on the results to prevent frequent infections.

Vitamin A

Another infection fighter comes from animal or plant foods. Some of the foods that have Vitamin A in abundance are:

• Carrots
• Pumpkin
• Sweet Potatoes
• Cantaloupe
• Left Vegetables
• Butternut Squash
• Tuna
• Fish
• Meat 
• Diary

So the above are some of the foods that can strengthen the immune system against COVID and other infections. While fresh produce is recommended, if not available frozen food is also an option as it can boost the immune system when sick.

The body needs a bouquet of nutrients to shore up your defense to support the immune system much more than others. So having the right Vitamins to boost your immune system can help you stay hale and healthy.
