Powerful nutrition for your immune system

Vitamin C

helps protect cells from oxidative stress, the reduction of tiredness, fatigue and increases iron absorption.

Vitamin D3

stimulates the initiation of white blood T cells which play a central role in the adaptive immune system’s response to the invasion of antigens (foreign substances) in the body.

Quercetin

is a plant bioflavonoid which plays an important role in helping your body combat free radical damage, which is linked to chronic diseases. Quercetin is also an all-natural zinc ionophore.

Zinc

controls immune system messaging within the cells and is also an antioxidant and anti-inflammatory

Scientifically inspired by an extraordinary doctor.

Inspired by the Zelenko Protocol, this vitamin, flavonoid and elemental zinc complex works synergistically to support the body’s innate and adaptive immune system.

What occurs to your immune system if you are deficient in zinc?

Firstly your Thymus gland starts to shrink (known medically as Thymic Atrophy). Your thymus is a small gland in the lymphatic system that makes and trains special white blood cells called T-cells. The T-cells help your immune system fight disease and infection. A zinc deficiency creates defective white blood cells which impairs your immune system’s ability to respond to infections effectively. This means you will increase the duration of the infection and increase your body’s inflammatory response. In addition there is an increased level of oxidative stress (free-radical collateral damage) which makes you even more susceptible to infections and bacteria, setting you on a downward spiral of persistent or repeat bouts of infection.

Where can I get zinc?

As there is no dedicated compartment for zinc storage in the human body, zinc has to be continuously replenished by your diet. Zinc is absorbed by the body via the intestines. Zinc can be found in many foods including red meats, poultry, seafood… oysters have a particularly high zinc content and so do pumpkin seeds. But… there are certain things in our food which can lower the absorption of zinc called Phytates and Oxalates – Phytates can be found in cereals, breads, corn, rice and pasta (foods which are abundant in our Western diets) – Oxalates in foods such as spinach, almonds and chocolate. People who drink excessive alcohol also may not absorb zinc normally. Like most things in your diet it is about balance and being aware that too much of any of these could steer you towards being zinc deficient.

Immune support

Zinc Ions are a non-fat-soluble mineral that can’t move through the fat-based cell membrane. Therefore, it needs help to cross the cell membrane from special transport systems called ionophores. An ionophore has the ability to ‘open the gate’ to a cell to allow the zinc ions to be absorbed. This is where Quercetin comes in. Quercetin is a natural zinc ionophore. Quercetin is a plant bioflavonoid found in many types of fruits and vegetables. It has powerful antioxidant and anti-inflammatory effects and has recently been studied for its potent antibacterial and antiviral benefits. Quercetin is one of the most abundant antioxidants in the diet and plays an important role in helping your body combat free radical damage, which is linked to chronic diseases.

Vitamin C supports cellular functions, while Vitamin D3 initiates white blood cell responses.
Quercetin helps zinc pass through cell walls, enabling it to affect cellular responses to infections and inflammation.
Zinc, in turn, modulates immune system messaging and exhibits antioxidant and anti-inflammatory effects.
Supports overall immune health.
May help combat oxidative stress and chronic diseases.
May aid in reducing tiredness and fatigue.
Suitable for vegetarians and packaged in plant-based compostable packaging.
