It's time to take immune health seriously.

When we think about health and fitness supplementation we often think about things like performance, recovery, optimizing our metabolism, joint health, etc. For some reason we seem to skip over one of the most important aspects; immune health.

We’re bombarded every single day by physical stressors (i.e. exercise), environmental stressors, poor food choices, not enough sleep, even things like pollutants and chemicals, yet we still look past immune health.

Optimizing immune health & function unlocks our body’s ability to operate efficiently.

Sometimes we take our immune health for granted. We don’t think about it until our natural defenses get cracked and boom, you’re sick. We typically then get into defense mode. Plenty of water, vitamins and rest.

Why not optimize your immune function before that happens? Fortify your defenses with Immune Boost. Stay on the offensive to keep your body running at full strength.

What makes Immune Boost different than other immune or vitamin supplements?

Maximum Dosing for Maximum Benefits.

Every carefully selected vitamin & natural ingredient in Immune Boost™ has been dosed at the highest end of the spectrum to ignite your immune system immediately.*

Respiratory System Focused.

Astragalus is asserted to be a tonic that can improve lung functions, promote healing, reduce fatigue, support the immune system and help prevent colds & upper respiratory infections.*

We went one step further and added Serrapeptase for additional respiratory support.*

If you are unfamiliar with this natural ingredient here’s the scoop...

Your body naturally makes the enzyme; serrapeptase. You can also take serrapeptase as a dietary supplement, usually in capsule form. This enzyme degrades dense proteins that most other enzymes can’t touch.

Serrapeptase may increase the clearance of mucus and reduce inflammation in the lungs in people with chronic respiratory diseases.*

Packed With Foundational Immune Ingredients.

Vitamin C is a powerful antioxidant that can strengthen your body’s natural defenses. This might be one of the most researched and proven immune boosting ingredients in the world.*

Immune Boost contains a massive 2,000mg per serving of Vitamin C per serving - putting this at the high end to keep you running in tip-top shape.

Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus, and facilitating normal immune system function.*

In addition to its primary benefits, research suggests that vitamin D helps to reduce your likelihood of developing the flu.*

Research shows that supplementing with a high dose of vitamin D may be harmful with low levels of Vitamin K. We added a complete K-Complex (K1+K2 (MK-4), K2 (MK-7)) to help offset this.

Evidence suggests that if zinc is taken within 24 hours after cold symptoms start, the supplement can help shorten the length of colds.*

Immune Boost is packed with 50mg of Chelated Zinc for easy absorption.*

Echinacea is best known for its beneficial effects on the immune system. Numerous studies have found that this plant may help your immune system combat infections and viruses, which could help you recover faster from illness.*

Fatigue Fighting Reishi Mushrooms

Reishi’s effects on the immune system are often most emphasized, but it has other potential advantages as well.*

These include reduced fatigue and energy, as well as improved quality of life.*

Natural Immune Booster

Beta Glucan is an all natural polysaccharide and classified as a clinically proven immune modulator, meaning it "modulates", stimulates, and supports your immune System.*

Beta Glucan is a fiber-like molecule which activates your immune cells - it's your natural weapon to become and stay healthy.
