Environmental factors, age, quality of food and persistent stress all drain our bodies' resources.

This is where nutritional supplements come into play. They provide a convenient and effective way to fill nutritional gaps, ensuring that we get the essential vitamins, minerals, and other elements that help our immune system, boost energy, and improve general well-being. By incorporating supplements into our daily routines, we may protect our body’s immunity against the stresses of contemporary life, allowing us to remain vibrant, active, and ready to face whatever comes our way. If your diet lacks these vital nutrients and your immunity is low, don’t fret since we have a ready reference of supplements to boost immunity for you. These supplements are advantageous for the body as they provide multiple nutrient benefits also minimising the risk of deficiencies.

Here are 15 supplements to boost your immune system:

1. Vitamin C:

Vitamin C is widely known for its ability to support the immune system. It acts as a potent antioxidant, protecting cells from free radical damage. This vitamin also promotes collagen formation, which is essential for maintaining healthy skin and promotes the healing process. Furthermore, vitamin C improves the activity of white blood cells, which is essential for fighting infections. It facilitates a variety of cellular processes that contribute to a strong immune response. Regular vitamin C intake, whether through diet or supplementation, can aid in the maintenance of a strong immune system, minimising the duration and severity of common colds and other illnesses.

A 2017 study published at NCBI states that vitamin C appears to have a wide range of positive impacts on cellular activities of both the innate & adaptive immune systems. Vitamin C supports the body’s fight against pathogens and promotes radical scavenging, potentially protecting against oxidative stress. Vitamin C also appears to be useful in preventing and treating respiratory and systemic infections via improved immune cell performance.

If you are looking for a reliable source of vitamin C supplements in the form of a vitamin C tablet, SteadC by Steadfast Nutrition can be your ideal pick.

Zinc is needed for a healthy immune system. It is essential for the growth and function of immune cells such as neutrophils and natural killer cells, which serve as the body's initial line of defence against infections. Zinc also has antioxidant capabilities, which protect cells from oxidative stress and damage. It promotes the formation and activation of T lymphocytes, which are essential for adaptive immunity and fighting specific infections. Zinc supplementation can also help reduce inflammation and shorten the duration and intensity of colds. Regular zinc intake, whether through diet or supplementation, is critical for maintaining a strong and effective immune response. Zinc deficiency can decrease immune function, leaving the body more vulnerable to infections. As a result, maintaining proper zinc levels is vital for overall health and immunity.

Zinc supports the body functions, including immune system function, such as faster healing of wounds, improving taste and smell, reducing age-related macular degeneration and certain skin diseases like dermatitis.

A 2017 study published at NCBI states that zinc can be regarded as an immune system gatekeeper, as almost all immune cells rely heavily on zinc for proper function. A zinc supplement is thus one of the best supplements to boost immunity.

3. Curcumin:

Curcumin, turmeric's main active component, has a number of immune-boosting properties. It has potent anti-inflammatory and antioxidant capabilities that help protect the body's cells from damage. Curcumin regulates the activation of numerous immune cells, including T cells, B cells, macrophages, and natural killer cells, improving their ability to respond to infections. Curcumin has also been proven to lower the production of pro-inflammatory cytokines, chemicals that can cause an excessive immune response. This can help with chronic inflammation and autoimmune disorders. Curcumin consumption regularly, whether through turmeric or supplements, can benefit the immune system by maintaining a balanced immunological response and lowering the risk of chronic diseases. It leads to the inhibition of inflammation, preventing certain immune-mediated inflammatory diseases like rheumatoid arthritis, multiple sclerosis & inflammatory bowel disease. It plays a critical role in the management of diseases due to its anti-bacterial, anti-viral, anti-fungi, hepato-protective & anti-tumour other than having anti-inflammatory properties.

4. Vitamin D:

Its deficiency is associated with an increased susceptibility to infections. Vitamin D boosts the pathogen-fighting abilities of monocytes & macrophages - white blood cells which are essential for immunological defence. It reduces inflammation and stimulates the synthesis of antimicrobial peptides, which help the body fight bacterial and viral illnesses. It is a fat-soluble vitamin that helps the body maintain calcium and phosphorus levels through proper absorption. Exposure to sunlight, ingesting vitamin D-rich foods, and taking supplements as needed can all assist in maintaining optimal levels and supporting general immunological function. To battle Vitamin D deficiency, it is recommended to consume a vitamin D capsule by Steadfast Nutrition. It comprises 2000 IU of vitamin D3.

A 2020 study published by the NCBI clearly establishes vitamin D's influence on the immune system is that preventing severe vitamin D deficiency enhances immunological health and reduces vulnerability to autoimmune illnesses.

5. Vitamin B Complex:

The vitamin B complex, which includes B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin), is essential for a healthy immune system. Each B vitamin has a distinct role in immune support, ranging from immune cell energy production to inflammation reduction and antioxidant protection. B vitamins help maintain the health of the skin and mucous membranes, which act as barriers against infections and are required for the formation and function of white blood cells, lymphocytes, and antibodies. Vitamins B6, B9, and B12 are very necessary for the formation of new red blood cells and transporting oxygen, helping improve the body's ability to combat infections and maintain overall immune health.

A 2022 research paper published at NCBI states riboflavin's active forms are antioxidants, which are essential for cellular respiration and immunological function.

Moreover, pyridoxal 5′-phosphate, the active form, helps several enzymes accomplish a variety of body functions, including maintaining appropriate homocysteine levels and supporting immunological function and brain health.

6. Spirulina:

Spirulina, a blue-green algae, or chlorophyll-containing bacteria is well known for its immune-boosting effects. It contains proteins, vitamins, minerals, and antioxidants that promote general health. Spirulina boosts the immune system by raising antibody production and the activity of natural killer cells and macrophages, all of which are required to fight infections. Its high antioxidant concentration helps immune cells resist oxidative damage. The presence of vitamins E, C, and B6 helps boost the production of WBCs, reduce chronic inflammation and promote a healthy immunological response. Regular spirulina use, whether as a supplement or as part of a healthy diet, can help boost the immune system and increase the body's ability to fight infections.

In a research study conducted by NCBI in 2022, it was found that spirulina can prevent immune cell changes while strengthening eosinophils and basophils. As a result, the spirulina supplement helped to stabilise the leukocyte-monocyte-eosinophil-basophil ratio. Spirulina also has a good effect on rapid-onset allergies and responses to parasites or pathogenic bacteria, which helps  improve immunological control.

7. Shilajit:

Shilajit, a naturally occurring mineral found largely in the Himalayas, is known for its numerous health advantages, including supporting the immune system supporting and accelerating the process of rejuvenation. Shilajit, which is high in fulvic acid, vitamins & minerals, boosts the immune system by increasing the production of lymphocytes and macrophages, both of which are essential for fighting infections. Shilajit contains fulvic acid, which improves immunological function. Its antioxidant capabilities assist in protecting immune cells from oxidative stress and damage, scavenging free radicals, whilst its anti-inflammatory characteristics reduce chronic inflammation, promoting a healthy immunological response. Shilajit taken on a regular basis can help strengthen the immune system and boost energy levels.

8. Ginseng:

Ginseng, specifically Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius), is well-known for its immune-boosting qualities. It contains active molecules called ginsenosides, which have antioxidant and anti-inflammatory properties that benefit immune health. Ginsenosides help regulate immune homeostasis and have been shown to boost the function of immune cells such as macrophages and natural killer cells, which are important for detecting and eradicating infections.

9. Selenium:

Selenium is a vital mineral that promotes immune function and general health. It serves as an antioxidant, protecting cells from free radical damage. Selenium is also essential for the effective functioning of the immune system since it promotes the activity of numerous immune cells, including the T cells and natural killer cells, and helps boost the production of white blood cells which are essential for fighting infections and malignant cells.

According to research, selenium deficiency can impair immunological responses, rendering people more susceptible to infections. Adequate selenium levels improve immune defence mechanisms. Selenium is frequently found in nuts, seeds, seafood and lean meats. Supplementation may be required by those with a deficiency to maintain adequate immunological function.

10. Vitamin A:

Vitamin A is necessary for a robust and healthy immune system. It is essential for a variety of immunological processes, including immune cell growth and differentiation (T cells, B cells, and macrophages). Vitamin A is involved in immune system development, playing regulatory roles in cellular immune responses and humoral immune processes. Furthermore, vitamin A contributes to the integrity of epithelial barriers, such as the skin and intestinal membranes, which serve as the body's first line of defence against infections.

A 2022 study published by ScienceDirect states that recent multidisciplinary investigations have helped to better understand the interaction between vitamin A and the immune system. Dietary retinol in the form of retinoic acid usually influences mucosal immunity and immune tolerance. Carotenoids, the precursor of vitamin A, show an immuno-modulatory effect on the system.

11. Omega 3:

Omega-3 fatty acids, notably EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), have an inhibitory effect on immune cells, preventing infections, which is beneficial for the immune system and overall health. These necessary fatty acids are most commonly found in fatty fish such as salmon, mackerel, and sardines, as well as flaxseeds, chia seeds, and walnuts.

Omega-3 fatty acids are anti-inflammatory, which can help modulate immunological responses of B & T- Lymphocytes. They regulate the generation of inflammatory mediators and have the potential to reduce chronic inflammation, which has been connected to a variety of diseases and ailments. Omega-3s promote a healthy immune response by controlling inflammation, allowing the body to defend itself against infections and preserve optimal health. To get the benefits of Omega-3, fish oil supplements are often advised by health practitioners. If you are looking to find the best fish oil supplement, Steadfast Nutrition’s Fish Oil can be your ideal pick.
