Calcium – important for muscles and nerves

Today’s article is dedicated to the mineral calcium (Ca), also known as calcium. It is the most abundant mineral in the human body, found mainly in bones and teeth. Calcium gives them stability as a compound and is indispensable for the formation of new hard tissue.

The mineral is also essential within the cells for the excitation of nerves and muscles, but also plays an important role in blood clotting, heart rhythm and important metabolic processes. For the blood plasma, calcium is released from the bones, which serve as a calcium depot, as soon as the need arises.

Where can you find it in BERTRAND?

Calcium is found in BERTRAND mainly through the alga Calcareum Lithothamnium. It comes from the French coast and is processed into a fine powder for our product. No other additives are added that could lead to possible contamination. The excellent bioavailability of Lithothamnium also makes the alga a great alternative to existing calcium sources and is purely vegetable. In our classic and active versions, however, it is also found through the milk powder.

Calcium intake

Not all the calcium we ingest is absorbed. The rate of resorpion depends on the composition of the diet, but other factors such as age and sex can also influence it. Also the own movement activity plays an important role in the utilization of calcium. The mineral is transported via the intestinal wall into the blood, where it activates the “calcium sensor” and thus triggers hormonal changes.

Facilitate calcium absorption

Vitamin D plays a decisive role in the absorption of calcium. The 20µg of this “sun vitamin” contained in BERTRAND per daily bag is provided by the tasty shiitake mushroom.

Vitamin D completely without food intake? Under optimal conditions, a quarter of an hour of sun exposure of the face, hands and forearms is sufficient for the production of several thousand units of vitamin D.

Iron: Important for oxygen transport and cellular respiration

Today’s article is dedicated to iron (lat. Ferrum, FE) – an essential trace element that the body cannot produce on its own. It has to be supplied to it, for example through nutrition, because the organism needs this trace element in order to function ideally. Iron plays a role above all when it comes to the transport of oxygen in the blood and cellular respiration. It is essential for the formation of haemoglobin, i.e. for the production of red blood cells. It also strengthens hair, nails and muscles. Iron absorptionExplained in a few words, iron binds itself to various organic molecules that are present in the organism. It is found
