Deficiency of B vitamins in the human body manifests itself with some symptoms. The most obvious symptoms are dryness or roughness of the skin and hair health, since vitamin B is the basis of their energy metabolism, other symptoms may be lack of appetite, constipation, insomnia and acne.
Their absorption is conditioned by some dietary and psychological factors. In fact, it is reduced in the presence of stress or by the excessive consumption of some foods such as coffee, sugar, alcohol, by the use of some medicines such as sleeping pills or contraceptive pills or by sulphonamides or in the presence of infections.
Instead, absorption is favored by the presence of other vitamins, such as C and E, as well as calcium and phosphorus. In the past it was thought that B vitamins were a single vitamin: further research has shown that they are different molecules that are often found together in the same foods.
But what is vitamin B for?
These vitamins have very useful properties for the human organism, in fact they play an essential role in the normal functioning of the nervous system and the muscle tone of the gastrointestinal area.
Furthermore, they are fundamental for the correct functioning processes of the skin and hair and therefore also for the scalp, mouth and eyes and for the correct functioning of the liver. They also contribute, as co-enzymes, in the transformation of complex carbohydrates into glucose, used by the body to produce energy, and are crucial for the correct metabolism of lipids and proteins.
Finally, they are fundamental for the correct functioning and protection of the peripheral nervous system. Since the human body is not able to synthesize them on its own, it is important to take B vitamins daily with a healthy and varied diet.
B vitamins are found in various foods such as cereals, legumes, green leafy vegetables, but also in those of animal origin such as milk and its derivatives, eggs, meat and fish. B vitamins are found in a large amount of foods of both plant and animal origin.
Each B vitamin is present in greater quantities in certain specific foods, so it is a good idea to find out specifically for each individual vitamin.
