Vitamin D and sun, why are they so important?

Vitamin D is essential for our body and unlike other vitamins, is introduced only in part by means of foods because it is produced for the most part (about 80%) by our body, employing metabolic processes that are triggered by the exposure to sunlight, activating the vitamin D of those foods.
One of the functions of vitamin D is to fix calcium in the bones, properly mineralized and this operation is essential during all stages of life: in children, because vitamin D, calcium and phosphorous foster physiological growth of the whole skeletal system; in adolescents, because they are in a phase where about 40% of the whole final bone mass is being developed; during pregnancy, in order to develop the child ‘s skeleton; after 50 and especially in women with the onset of menopause, because the bone mass may be reduced considerably and risk of osteoporosis increases.
Therefore, vitamin D and calcium must be consumed in adequate amounts.

Given the importance of vitamin D in relation with sun exposure, we must exploit all the summer’s advantages and fully recharge us, and thanks to the sea, we also recharge with iodine.
An adequate amount of vitamin D shall be ensured by eating oily fish, such as herring, mackerel, salmon and sardines, and calcium-rich foods, such as milk, yogurt and cheese.
For example, “Grana Padano” cheese concentrates all nutrients and provides great amount of proteins with high biological value, as well as many minerals, including calcium and vitamins such as A, E and those of the B group, including the very important B12, in addition to providing a good dose of vitamin D.

Everyone at the table with vitamin D, calcium and Phosphorous: one 12g Grok sachet with its milk proteins provides 25% of our daily requirement of CALCIUM, and 19% of the daily requirement of PHOSPHOROUS of an adult.
Grok is a unique, tasty, genuine source of energy that is always ready and available, with the typical Italian flavor!
