Our number one supplement for immune support
Vitamin C and the immune system
Vitamin C plays an important role in the normal function of the immune system. The body cannot produce vitamin C on its own. This means intake depends fully on diet.
In a busy lifestyle, eating enough fruit and vegetables can be difficult. These foods are the main sources of vitamin C. A high-quality supplement can therefore be a useful addition. Vitamin C in the form of calcium and magnesium ascorbate is well absorbed and biologically available. In combination with copper and zinc, vitamin C supports the immune system.
What is buffered vitamin C
Ascorbic acid is the most common form of vitamin C and occurs naturally in food. It is also the form used in many supplements. This acidic form can cause stomach or intestinal discomfort at high doses.
This formula uses calcium and magnesium ascorbate. This mineral-bound form buffers vitamin C and reduces acidity. As a result, it is gentler on the stomach and intestines. The buffered structure also supports higher bioavailability and improved absorption.
Manganese, zinc, and copper as antioxidants
The formula includes the trace elements manganese, zinc, and copper. These minerals act as cofactors for superoxide dismutase enzymes. These enzymes help neutralize free radicals formed during energy production in the mitochondria.
These antioxidant minerals are not consumed during this process. This allows them to remain active and effective. Their presence adds value to the immune-focused formula.
Zinc as a key mineral for immunity
Zinc is one of the most important trace elements in the body. It supports many biochemical processes, including protein synthesis, cell division, and tissue formation. Zinc also contributes to normal immune function.
Copper supports iron transport
Zinc and copper interact closely in the body. High zinc intake can lower copper status. For this reason, copper is included alongside zinc in the formula.
Copper also supports immune function and contributes to normal iron transport in the body.
OPC supports nutrient effectiveness
OPC, derived from grape seed extract, is an antioxidant that is absorbed in the small intestine and distributed throughout the body. OPC is often associated with oxidative stress and support for the heart and blood vessels.
The main reason for adding OPC to this formula is its ability to support the effectiveness of other nutrients in the blend.
Quercetin and L-glutathione
Quercetin is a plant-derived flavonol that often occurs together with vitamin C in nature. It is found in high amounts in the outer layers of red onions.
L-glutathione as a powerful antioxidant
L-glutathione is a tripeptide made from cysteine, glutamine, and glycine. The body can produce it in the liver. Glutathione plays a central role in antioxidant activity and helps regenerate other antioxidants such as vitamin C, vitamin E, alpha-lipoic acid, and coenzyme Q10.
Together, quercetin and L-glutathione create a strong synergistic combination.
