15 Criteria For An Optimum Immunity Support Supplement

Are you scared of all those unseen microbes causing havoc to humanity?

Fear not!

Your immune system does an excellent job of defending you against disease-causing microbes.

Along with healthy lifestyle choices you’ll have to nourish your immune system with proper nutrients to maximize its efficiency.

If your body lacks even in a single nutrient, it may ultimately change your immune response. That’s why you need to follow a healthy diet and proper supplementation to safeguard your immunity levels.

Studies⁽¹⁾ show that deficiencies in selenium, iron, zinc, copper, folic acid, and vitamins B6, A, C, E, and D could alter your immune responses.

Poor nourishment could lead to a higher risk of viral, bacterial, and other infections. The good news is that the right immune supplement can help support optimal functioning of your immunity and respiratory system.

But, if you pick the wrong one, results could be minimal or may even cause harm. To give you a clear idea let’s start with the basics.

Immune Supplements: Why Are They Important?

Nourishing foods ⁽²⁾ rich in vitamins and minerals could help your immune system fight off illness. For example, take vitamin C, it's one of the biggest immune system boosters. A lack of it may make you prone to sickness.

Likewise, vitamin B6 is essential to support biochemical reactions in your immune system. Similarly, vitamin E is a potent antioxidant that helps your body fight off infection.

All is well; until your nutrient intake is sufficient. But if you become deficient in one or more essential nutrients, your immunity may suffer.

As you live your life in the fast lane, though you eat a healthy diet, there could be some gaps in it––which may lead to deficiency.

A supplement that fills all the gaps could be the best possible solution.

So if you're wondering how to choose the best supplement, here are 15 research-based criteria to select your best supplement.

The 15 Criteria For Choosing An Optimum Immune System Supplement

1. Vitamin C

Vitamin C has many impressive health benefits. It's an essential vitamin meaning your body can't produce it. The recommended daily allowance (RDA) of vitamin C for women is 75 mg, while for men, it's 90 mg.

While you can take vitamin C from fruits and vegetables, many people turn to supplements to obtain this vitamin.

Vitamin C helps in the formation of white blood cells called phagocytes and lymphocytes and helps protect against infections. ⁽³⁾

It also helps white blood cells to function effectively and protects them from damage by harmful free radicals.

Moreover, vitamin C forms an integral part of your skin's defense system, where it acts as an antioxidant and helps strengthen your skin's natural barrier. ⁽⁴⁾

Research studies ⁽⁵⁾ have shown that vitamin C helps to heal wounds faster. What’s more, low vitamin C levels could lead to poor health outcomes.

2. Vitamin E

Being a powerful antioxidant Vitamin E helps your body fight off infection. This fat-soluble vitamin acts as a first line of defense against cell damage. Also, it optimizes the normal functioning of immune cells.

Vitamin E comprises eight different compounds, and the most active one in humans is alpha-tocopherol. When your body gets exposed to free radicals, it causes premature aging.

Likewise, free radicals weaken healthy cells and may cause cancer and heart disease. They even reduce the lifespan of your cells. Being a powerful antioxidant vitamin E reduces free radical damage and slows down the aging process of your cells. ⁽⁶⁾ ⁽⁷⁾

3. Vitamin B6

Also known as pyridoxine, vitamin B6 is a water-soluble compound that your body needs for immunity and other functions.

Vitamin B6 has several health benefits; it reduces symptoms of depression, promotes brain health, may prevent anemia, and could treat premenstrual syndrome. Also, it may prevent clogged arteries and reduce the risk of heart disease.

Vitamin B6 ⁽⁸⁾ acts as a cofactor of certain enzymes and helps them carry out their respective biochemical functions. Moreover, this vitamin helps to absorb vitamin B12 that helps in the formation of immune cells and red blood cells—thus increasing the efficiency of your immune system.

4. Zinc

Zinc is an essential nutrient that plays many vital roles in your body. It helps in gene expression, immune function, and enzymatic reactions.

Also, it aids in DNA synthesis, protein synthesis, wound healing, and growth and development. Zinc is essential for cell signaling and immune cell function. If you're deficient in Zinc, it could lead to a weekend immune response.

When you take zinc supplements, it activates particular immune cells and reduces oxidative stress. A research review 9 says that 80-92 mg of Zinc per day could reduce the length of the common cold by 33 percent.

Moreover, zinc supplements could reduce infections and promote immunity in older people. ⁽¹⁰⁾

5. Elderberry

Ancient Egyptians used elderberries to enhance their complexions and treat burns. Likewise, Native Americans used it to treat infections. Today this medicinal plant is used to treat cold and flu symptoms.

Elderberry being high in nutrients helps to improve cold and flu symptoms. Likewise, it’s high in antioxidants and may improve your heart health. A randomized study of 60 adults found that those who drank 15mL of elderberry syrup four times a day cleared up faster than those who took a placebo syrup. ⁽¹¹⁾

This medicinal plant may enhance your immune response. Animal studies show that elderberry polyphenols increased the number of white blood cells and thus increased immune response. ⁽¹²⁾

6. Echinacea

Also called the purple coneflower, Echinacea is a popular herb worldwide. This flowering herb is best known for its effects on immune function, common cold or flu. Also, it helps to treat pain, inflammation, migraines, and other health issues.

Echinacea plants contain various active compounds. Some may have antimicrobial and antiviral properties, while others may support the immune system. ⁽¹³⁾

Several studies say that Echinacea may fight viruses and infections and help you recover faster from illness. ⁽¹⁴⁾ This herb also helps to treat blood sugar levels, reduces feelings of anxiety, and skin conditions.

7. Garlic

For centuries garlic has been used as a food ingredient and medicine. Garlic may contain compounds that help your immune system fight germs. Whole garlic contains a compound called alliin.

When garlic is crushed, this compound turns to Allicin. It gives garlic its distinctive smell and taste. Allicin is unstable and converts to sulfur-containing compounds that increase the medicinal properties of garlic.

These sulfur compounds help to increase the efficiency of specific white blood cells when they fight with viruses such as common cold or flu. ⁽¹⁵⁾ ⁽¹⁶⁾

8. Turmeric

This wonder spice may be the most potent nutritional supplement in existence. It contains bio-compounds with powerful medicinal properties. Indians have used turmeric for thousands of years as a food ingredient and as a spice.

The compounds present in turmeric are called curcuminoids, out of which curcumin is the most potent ingredient. You need at least 1 gram per day to see its effects, so the best option would be to get it through supplements.

Scientists say that chronic low-level inflammation could play a significant role in cancer, heart disease, metabolic syndrome, Alzheimer’s, and various degenerative diseases. Therefore anything that fights chronic inflammation could help treat or prevent these conditions.

Curcumin is strongly anti-inflammatory. It blocks NF-kB, a molecule that causes gene-related inflammation. So the key takeaway is curcumin fights inflammation and may increase immunity even at a molecular level. ⁽¹⁷⁾ ⁽¹⁸⁾

9. L-Glutamine

Glutamine is a building block protein and is an essential part of your immune system. Glutamine is an essential fuel source for immune cells, including specific intestinal cells and white blood cells.

This amino acid supports the immune cell activity in your gut, helping prevent infection and inflammation and soothing the intestinal tissue. ⁽¹⁹⁾

Studies show that glutamine supplements may lower infection rates, enhance health, and may lead to shorter hospital stays after surgery.

Moreover, they have been shown to increase survival rates and lower medical costs in critically ill patients. ⁽²⁰⁾ ⁽²¹⁾

10. Probiotic: Lactobacillus Acidophilus

Nowadays, probiotics are becoming popular food supplements. Lactobacillus Acidophilus is a common type of probiotic present in supplements, yogurt, and fermented foods.

These healthy bacteria can boost your immune system and reduce the risk of viral infections. Some studies even say that probiotics can improve and prevent the symptoms of the common cold.

For example, a study of 326 children taking L. acidophilus probiotics for six months reported reduced coughing by 41%, fever by 53%, and antibiotic use by 68%. ⁽²²⁾ ⁽²³⁾

Interestingly, inside your gut are millions of live microorganisms that help protect your body from infection and regulate metabolism and the immune system.

Lactobacillus Acidophilus increases the amounts of these healthy bacteria in your intestines and supports your gut health by fighting off infections.

11. A powerful Combination of Ingredients For Enhanced Effectiveness That Your Supplement Must-Have

A study published in 2012 by the US National Library of Medicine National Institutes of Health stated that the important immune system proteins were increased when Elderberry was COMBINED with Acidophilus. ⁽²⁴⁾

Thanks to this study, it's easy to conclude you need to look for a supplement that includes Elderberry AND ALSO the probiotic Lactobacillus Acidophilus for a DOUBLE DEFENSE and to MAXIMIZE optimum immune support.

12. Avoid Supplements With Too Many Ingredients

“Fairy dusting” is basically including a tiny amount of a nutrient in a formula and listing the ingredient on the product label, even though the dose is far too small to be effective. This commonly happens when supplements include too many ingredients in a formula.

Unfortunately, that is an alarmingly common practice in the nutritional supplement industry. You must purchase supplements from a reliable company with all the quality and ethical practice certificates.

13. Avoid Gummies - They Are Not As Effective As You Think And Could Be Dangerous

Most gummies contain artificial colors. Some of those colors have been linked to various health issues and they defeat the purpose of taking vitamins.

Although gummies may look more appealing, the vitamin's active ingredients have been degraded by exposure to light, air, moisture, heat, or poor storage conditions.

So no, taking gummies is not the same as taking capsules. It’s not worth it to compromise your immunity just because gummies seem to taste better.

14. Supplements With Fewer Ingredients Hardly Work

We may think by taking supplements with 3 - 4 ingredients; we are increasing the chances of getting better results and receiving double effectiveness.

But the truth is that the secret of a powerful immunity support formula starts with the RIGHT COMBINATION OF CERTAIN NUTRIENTS (the ones we mentioned above) so your body gets the immunity support it needs to keep a healthy level.

15. Supplement Must Be Made By A GMP Certified And FDA Registered Facility

You need to make sure the supplement is manufactured by an FDA registered facility, the manufacturer has GMP (Good Manufacturing Practices) certification and follows all pertinent FDA regulatory requirements.

Investing in your health and wellness would be the best decision you will ever make, and for your safety, the least you can do is to use products from a faithful company committed to provide the highest-quality products.
