Zinc and Selenium are two essential trace minerals pivotal for numerous biological processes. These minerals must be obtained through our diet or supplementation, as our bodies cannot naturally produce them. Their synergistic interaction amplifies the immune response, enhances skin, hair and nail health, and aids in maintaining reproductive well-being.
The need to know
What are the benefits?
Supports immune system
Helps with detoxification
Zinc plays a fundamental role in the immune response by controlling the development and function of cells mediating innate immunity, such as neutrophils and natural killer cells. It also influences the generation of cytokines, signalling molecules that mediate and regulate immunity, inflammation, and hematopoiesis. Furthermore, zinc can increase intracellular levels of the antioxidant glutathione by up to 30%, protecting cells from oxidative stress.
Selenium, a constituent of the enzymes glutathione peroxidase and thioredoxin reductase functions as an antioxidant to help the body fight oxidative damage and protect cells. It is also essential for the proper functioning of the thyroid gland and supports the production of DNA and reproduction. A selenium deficiency can lead to impaired immune function and cognition and a greater risk of age-related diseases such as heart disease and cancer.
How will I know its working?
You might experience an improved immune response, healthier skin, hair, and nails, and better overall well-being. The effects are often subtle and may become noticeable over weeks or months.
When to take it?
Take 1 tablet daily with food and water, unless specified otherwise on the sachet.
Serving Size 1 Vegetarian Capsule

Both zinc and selenium are found in a variety of foods. Oysters contain the highest amount of zinc of any food, and Brazil nuts are one of the richest sources of selenium.
Zinc deficiency affects around 2 billion people worldwide and is associated with many diseases, including impaired immune response.
