In human form, it’s your bodyguard. In object form, it’s your shield. Inside the body, it’s natural resistance. The immune system has always been an essential form of protection.

However, just about everything in this world, perfection doesn’t exist and when not in its well-functioning state, a weak immune system can be a primary cause of getting sick. While there are various reasons on where one might have gotten it - whether it’s from physical contact, touching infected surfaces or food intake, it all goes down to a deep root called immunity. 

The Power of the Immune System

The immune system is a complex system of various cell types distributed throughout the body. It distinguishes and eliminates pathogens, tolerates non-threatening sources of antigens, and maintains a memory of immunological encounters. Research is continuously exploring its complexity, but there have been existing studies already that offer beneficial information to the public. 

While the system itself is complex, there are proven simple ways to start off with to make sure you’re working towards a healthy lifestyle. Some of these are found in the nutrients on the food, vitamins, and supplements that you take. Protect yourself from the flu season with the right nutrients!

The Nutrients Squad

Good nutrition is an essential part of a healthy immune system. Save your worry and your body by making sure you are taking the right supplements.

Vitamin C

This is a superior immunity booster on the list. According to 148 animal studies, Vitamin C prevents infections that are caused by bacteria and viruses. This water-soluble vitamin helps fight infections and is known for aiding in the creation of collagen which tends to wounds, supports blood vessel walls, and forms a base for teeth and bones. The good thing about this is that it is found in many foods such as citrus fruits and leafy green vegetables like spinach, bell peppers, brussels sprouts, and more. It can also be found in our NAD revival anti-aging supplement, which comes along with other immunity-boosting ingredients such as Vitamin D, Vitamin E, Biotin, and Astaxanthin, which are also discussed further below.


This nutrient helps wounds heal, reduces period length and severity of common colds, controls the pace of immune response and inflammation, and is also involved in various aspects of cellular metabolism. Zinc is usually found in foods such as oysters, crabs, lean meat, poultry, and beans. It comes in a variety of supplements such as Zinc gluconate, Zinc acetate, Zinc sulfate and other various types depending on its health impact.


Another member of the nutrient squad is found to have an impressive effect on the immune system, which involves a 2014 study on how it controls and regulates the body’s response to eliminate diseased cells. Foods that contain selenium are found in garlic, broccoli, sardines, tuna, brazil nuts, and barley among others. As an antioxidant supplement, Selenium also has the ability to reduce DNA damage and may reduce the risk of certain cancers.

Vitamin E

If you’re into a good amount of consumption on nuts, sunflower seeds, fortified cereals, and spinach, you’re certainly rich in Vitamin E supply. This antioxidant is powerful and like Vitamin C, it helps your body in fighting infection. 


Iron is a trace mineral that is best known for transporting oxygen throughout the body. It comes in different forms and is mostly found on foods such as lean poultry, seafood, and vegetables such as kale, broccoli, and beans. 

Vitamin A

This fat-soluble vitamin’s role is to keep the skin and tissues in the mouth, stomach, intestines and respiratory system healthy. It has an antioxidant effect that strengthens the immune system to fight against infection. The menu for Vitamin A is pumpkin, cantaloupe, squash sweet potatoes, carrots, broccoli, spinach, red bell peppers, apricots, eggs or foods labeled "vitamin A fortified”. You can also find this in our NMN cell revival joint pain supplement's finest ingredients list along with Vitamin C, D, E, and Biotin.

Vitamin B6

Vitamin B6 is a water-soluble vitamin that supports biochemical reactions in the immune system. It metabolizes amino acids which are the building blocks of proteins and contributes to the multiplication of cells. 

Vitamin D

Vitamin D works together with A, E, and K to help keep your eyes, skin, lungs, gastrointestinal tract, and nervous system in good repair. It’s also a vital nutrient in bone formation and helps build healthy bones. While the rest of the vitamins are found in plenty of food, Vitamin D is quite difficult to absorb from food, so it’s necessary to discuss with your doctor the right supplements to consume for the prevention of Vitamin D deficiency.

Folic Acid

Also known as Folate (natural form) and Vitamin B9, Folic Acid is also a water-soluble vitamin that helps build blocks of protein and multiply cells in the body. 


Biotin, also known as Vitamin B7 also has various health benefits including immune system function. In order to fight bacterial and viral infections, it does the increasing production of Th1 cytokines like IL-1β and IFN-γ which elicits the immune response.


A study also found that dietary Astaxanthin as an ingredient decreases oxidative stress, inhibits cancer cell growth, reduces bacterial load and gastric inflammation and enhances immune response in humans as well. You can find this in natural sources such as algae, yeast, salmon, trout, krill, shrimp and crayfish.  S-CELL Health’s Skin Revival supplements include Astaxanthin as one of its finest immunity-boosting ingredients along with Vitamin C, Zinc, Vitamin D, Biotin, and Selenium as well.
