Supports the immune system: The results of numerous scientific studies have proven that vitamins A, D3 and E have a positive effect on the immune system. The first one takes part in activation of many genes that are essential for natural bodily defense reactions. In addition to that, vitamin A improves the condition of mucous membranes that form a physical barrier able to stop viruses and bacteria from entering the body. Vitamin D3 stimulates production of cathelicidin – a naturally-occurring substance from the group of peptides that destroys microbes as it is released by white blood cells. Vitamin E is also important for the immune system because it stimulates multiplication of lymphocytes that get activated in response to infection. Iron has a supporting role in that regard since it participates in the production of cytokines that act as mediators in communication between the immune cells. This vitamin is also an ingredient of enzymes that are used to fight pathogens threatening the organism.

Improves physical performance: Numerous scientific studies indicate that supplementation with iron prevents symptoms such as chronic fatigue or apathy. This element is mainly involved in transportation of oxygen to the cells, allowing the key metabolic processes to occur. It is also an ingredient of myoglobin – a protein that builds skeletal muscles and helps to store oxygen reserves that can be used during more intense physical effort. Vitamin D3 helps to increase the amount of testosterone that gets synthesized. This hormone has an anabolic effect and stimulates development of muscles. What is more, cholecalciferol, together with calcium and vitamin K, improves bone mineral density, strengthening the skeletal system and making it more durable.

Supports a good mood: Vitamin D3 and iron are essential cofactors of tryptophan hydroxylase which is an enzyme that transforms tryptophan into 5-HTP – a direct precursor of serotonin. This neurotransmitter is responsible for mental comfort and resilience. On the other hand, the proper amount of vitamin E and iron is crucial for tyrosine hydroxylase that changes tyrosine into L-DOPA – a direct precursor of dopamine. It is worth noting that dopamine is also an important part of psychological well-being. Lowered activity of those two neurotransmitters may lead to significant mood deterioration. Vitamins E and D3 as well as iron participate in production of these essential brain chemicals. Moreover, calcium supports the release of those neurotransmitters to the synapses which is particularly important for the proper activity of serotonin.

Improves vitality: Of course, vitamins and minerals are necessary to maintain a good condition of the nervous system but they basically affect the entire organism. Calcium, vitamin D3 and vitamin K are all known for their beneficial effect on the bones and joints. That is why those compounds are particularly important for people struggling with osteoporosis. Additionally, calcium helps to control body weight as it stimulates expression of genes related to the breakdown of fatty tissue. Retinol is a key component of good eyesight and it’s because this substance participates in the synthesis of rhodopsin – a protein that occurs in the cells of the retina and plays an important role in processing visual stimuli. Tocopherol has a great influence on the condition of the skin. It has been shown that vitamin E can improve its hydration and elasticity. Vitamin K, on the other hand, helps to delay processes related to aging since it stimulates cellular metabolism and supports recovery of the body.
