4 signs your immune system may be depleted

1. Frequent illnesses: are you the person who catches every cold going around and dreads every WInter?

2. Slow recovery: Taking ages to bounce back from an illness can indicate a weakened immune response.

3. Fatigue: Persistent tiredness might be more than just a lack of sleep; it could be a sign of a struggling immune system.

4. Digestive Issues: A significant portion of your immune system resides in your gut. Digestive problems can be a sign of an imbalanced immune response.

Immune Cell Support

Our immune system comprises various cells, including white blood cells, T-cells, and B-cells, that work in tandem to fend off pathogens. Proper nutrition and targeted supplements can optimise their function.

Antioxidant Defence

Antioxidants are compounds that neutralise free radicals, unstable molecules that can damage cells. By bolstering the body's antioxidant defences, we can protect our cells from oxidative stress, reduce inflammation, and support overall immune function.

Gut Health & Immunity

A balanced microbiome aids in the production of essential vitamins supports the gut barrier, and modulates immune responses. Probiotics and prebiotics can help maintain this balance.

Essential Vitamins for Immunity

Each plays a unique role in bolstering immunity. Vitamin A fortifies skin barriers, Vitamin C boosts white blood cell production, Vitamin D modulates immune responses, and Vitamin E combats free radicals.

Pioneering Approach to Immune health

With years of research and expertise, our team has curated an Immune Booster Pack that goes beyond generic solutions. Recognising the intricate nature of the immune system, we've combined traditional wisdom with modern science to offer a comprehensive approach to immune health.

Whether it's flu season or you're just looking to boost your immune system, our pack is designed to support and strengthen your body's natural defences.

Immune health, inflammation and deficiencies

Common deficiencies like vitamin D, B12 and folate diminish the immune system. Ongoing inflammation and gut issues cause our systems to become depleted.

Our top 5 immune boosting supplements

  1. Glutathione is known as the master antioxidant for good reason.
  2. Vitamin C. Normally, we should get enough vitamin C from our diet, but requirements are much higher during illness. 1-2g per day can make a big difference.
  3. Vitamin D acts as a hormone in the body to upregulate the immune system. It has a complex modulating effect on T helper cells in the body.
  4. Quercetin is a natural flavonoid that supports immune health by exhibiting anti-inflammatory and antioxidant properties.
  5. Promultimax potent 20B CFU probiotic, expertly formulated with diverse strains and acid-resistant micro-encapsulation to fortify your gut health and bolster immune responses.
