What it does?


What it does?

Enhanced White Blood Cell Activity:

Supports the body's natural defense system by increasing white blood cell production and function. This enhanced activity leads to a faster and more targeted immune response.

Optimized Cellular Defense & Repair:

Promotes healthy cellular function by supporting key cellular processes involved in defense and repair. This optimization contributes to a more robust immune barrier against potential threats.

Balanced Inflammatory Response:

Helps regulate inflammation, ensuring your immune system responds effectively without causing unnecessary harm to your body.

Optimized Nutrient Absorption:

Ensures your body absorbs and utilizes essential nutrients efficiently, maximizing immune support and overall health.

60-Days Support for Unlocking the Body's Defense System

Experience the transformative power of our lab-tested formula, meticulously crafted for 60-day intake. Harnessing the synergy of essential minerals, potent vitamins, and natural plant extracts, it empowers your body to achieve optimal health and well-being.

Antioxidants and Essential Nutrients:

Vitamin C: Supports white blood cell production and function, essential for producing antibodies and other immune defenders. As a potent antioxidant, it also shields cells from damage caused by free radicals, byproducts of the immune response.

Vitamin A: Vitamin A plays a crucial role in supporting healthy vision and immune defense. It strengthens the body's first line of defense by keeping mucous membranes healthy, acting as a natural barrier against threats.

Vitamin E: This essential nutrient does more than just support a healthy heart. It acts like a shield for your cells, protecting them from harm. This helps keep your immune system strong and boosts your overall well-being.

B Vitamins (B1, B2, B3, B6, B12, Folic Acid): The potent vitamin B complex supports immune function, boosts energy, and maintains nervous system health by converting food into energy. It promotes cellular energy for metabolic activities. While diet is the best source, it's not always enough.

Garlic: Garlic enhances immune cell activity and reduces inflammation. It has been traditionally used to support overall immune health and well-being.


Zinc: This mineral supports the development and communication of immune cells, all while helping reduce stress and inflammation in your body.

Selenium: Selenium acts as a powerful antioxidant, protecting cells from damage and supporting a healthy immune system. Selenium also plays a role in healthy skin function.

Vitamin D3: Vitamin D, often called the "sunshine vitamin," is essential for strong bones, robust immune function, and maintaining a balanced mood.

Magnesium: Magnesium supports bone density, muscle relaxation, healthy sleep, and cardiovascular health. It also aids in muscle health, heart function, energy levels, bowel movements, blood pressure regulation, and calcium absorption.

Calcium: Calcium is crucial for bone health and plays a vital role in immune system cell signaling.

Potassium: Potassium is crafted to uphold a balanced fluid and electrolyte balance, aiding in physical endurance and optimizing muscle function during workouts, ensuring peak performance throughout your day.

Metabolic and Cellular Support:

Biotin: Biotin supports the health of hair, nails, and skin while also ensuring proper enzyme function. Since the body cannot produce or store biotin, a daily dose is essential to maintain optimal levels in the body.

Pectin: Pectin supports digestive health by promoting regular bowel movements and maintaining gut integrity. Additionally, it may help lower cholesterol levels and support overall heart health.

Amino Acids: Amino acids are the building blocks of proteins and are essential for muscle repair and growth, neurotransmitter synthesis, and immune function. They play a crucial role in supporting overall health and well-being.

Banaba Leaf Extract: Banaba Leaf Extract helps regulate blood sugar levels, indirectly supporting immune function by promoting overall health and well-being.

Cinnamomum Cassia Bark Extract: Cinnamomum Cassia Bark Extract possesses antimicrobial properties, supporting overall immune health and contributing to well-being.

Success Stories

Here are some success stories from customers who use Immune Booster


“The Best Product!”

“Great product, it really works!! Since I have started taking this, I notice I do not have the head colds like I used to get frequently. I travel for work and am always in different hotels, businesses and shaking lots of dirty hands. If I feel something coming on, I take and extra tablet or two throughout the day and feel great the next day.”

Emily, R.


“A Boost For Everyday!”

“I purchased this as an immune booster, with all the viruses floating around out there I wanted something to build my immunity. Whenever I feel a cold coming on or under the weather, I start taking two a day.I’m an individual who’s adamant about not taking pharmaceuticals or over-the-counter medicines with man made products. I prefer all natural ~vitamins, minerals and herbs. I’m really impressed with this product. Great value! Excellent to have in your household medicinal cabinet.

Nancy D. 23 June 2024
I bought this to help with some very occasional cold sore, but ever since I started taking it I've noticed an overall improvement in my well-being and immunity. I don't get sick as often as I used to. I also work out frequently and noticed a huge difference in the recovery time while I'm taking this. I stopped to take the supplement for a few weeks to see if it was really making a difference, and boy it did.
Kimmy L. 28 June 2024
I absolutely love this product. I was showing early signs of cold sores on my lips and I took these pills. Usually, I still get a cold sore breakout despite taking lysine tablets but with this magical product, I never got the cold sores!! These pills really helped prevent any cold sores breaking out on my lips. It does taste like soy sauce so I drink it down as soon as I pop them in. Still, such a holy grail for me! THANK YOU FOR MAKING THIS!!
