5% Nutrition Immune Defender 120caps

Of course, 5% Nutrition has what it takes to step up to the plate and create an advanced immune defense formula that will promote maximum immune health and function. We combined vitamins, minerals, herbs, and powerful nutrients to make the most comprehensive resistant health product on the market. Now more than ever before, your health should not be taken lightly. Whether you're a bodybuilder, powerlifter, or just want to be the healthiest you can be, get the ultimate in protection with Immune Defender.

Vitamin C 1000mg Vitamin C is the vitamin people turn to when it comes to immune support. For a good reason, it’s a potent antioxidant that’s important for a healthy immune system. Many companies use 500 mg or even 250 mg, but not 5% Nutrition. We gave it a potent 1g dose. (1)
Vitamin D3 125 mcg You might not think about Vitamin D when it comes to immune health. However, you can trust that we put it in Immune Defender for a specific purpose. White blood cells are one of the most critical components of your immune system. (2) Vitamin D supports the immune defense properties of white blood cells. (3) Additionally, Vitamin D deficiency may result in respiratory tract infections. Deficiency can be a problem during certain times of the year, such as in the winter. Also, many people aren’t spending a lot of time in the sun anymore, which can also cause significant deficiency. (4) This means that Vitamin D should be a primary ingredient in an advanced immune product.
Zinc Citrate 30mg Zinc is an essential trace mineral with a wide range of benefits. Research suggests that it can help shorten the duration of a cold and protect against respiratory tract infections. A zinc deficiency weakens the entire immune system. (5,6,7) Typically, zinc is not absorbed well by the body. Therefore it needs to be combined with another compound. While there are several forms, Zinc Citrate is one of the best forms of immune support.
Elderberry Fruit Extract 500mg This ingredient is a common and effective cold and flu ingredient. It’s a medicinal herb typically used to fight infections, such as bronchitis, sinusitis, the flu, and the common cold. The berries are high in antioxidants, flavonoids, polyphenols, and vitamins. No wonder it’s such a popular immune enhancer. (8)
Reishi Mushroom 400 mg – This is a medicinal mushroom with a long history of enhancing the immune system, stress reduction, and helps lower fatigue.
Echinacea 250mg This herb is a common cold and flu ingredient that effectively supports immune health and helps the body fight respiratory infections. No effective resistant formula should be without it. (9)
Turmeric Powder 105 mg – Turmeric has a positive impact on immune system health and function. One way it does this is by supporting white blood cell health. That means Turmeric works synergistically with vitamin D.
Olive Leaf Extract 50 mg – Olive leaf contains an active ingredient called oleuropein. This active ingredient has potent anti-inflammatory and antioxidant properties. (10) It’s in Immune Defender because of its antimicrobial and antiviral benefits, which can help fight respiratory tract infections.
N-Acetyl L-Cysteine 50 mg – N-Acetyl L-Cysteine promotes antioxidant production by increasing glutathione in the body, one of the most effective known antioxidants. Glutathione supports immune health and also combats oxidative stress. Additionally, it can help decrease cellular damage. (11)
Ginger Root Extract 50 mg – Many people think of Ginger as a relief for stomach discomfort or even a spice for food. However, Ginger supports normal immune health and function as well.
Odorless Garlic Extract 4:1 25 mg – Garlic is one of the most prevalent immune system boosters around. Many people take garlic whenever they experience the slightest cold or flu symptoms. It supports immune health by binding to cold and flu invaders, destroying them. It also works well with zinc to promote overall immune health. Of course, we use only the best odorless garlic.
