Low levels of vitamin D can lead to a subdepressive condition known as “winter or fall blues.” The outcome can be a winter depression. Psychological stability is important for maintaining the normal function of each person’s immune system. That is why it is important to measure the value of vitamin D in the blood quickly and safely. The cut-off values are about 50 nmol / l (or 20 ng / ml) in the blood. Values below 25 nmol / liter (or 10 ng / ml) suggest a critical deficiency of vitamin D. When the value of vitamin D in the blood is normal – then there is no need to use supplements. When the value of vitamin D in the blood is below normal – it is necessary to use vitamin D supplements, and spend enough time in daylight and fresh air.
Experts say that vitamin D is more of a hormone than a vitamin because it is ingested through sunlight. Vitamin D is a micro-nutrient and a key factor for strengthening and building bones. When the amount of vitamin D is sufficient in the body, it binds more easily to calcium and thus prevents the development of osteoporosis. Vitamin D is important for the immune system because it destroys cells that have entered the human body as the cause of various diseases.
Vitamin D deficiency weakens the human body. During the winter months, about 80% of the human population is deficient in this vitamin. Then the sunlight is dim and the daylight is short. People spend too little time outdoors during the winter months. Staying outdoors during the winter, cold, heat, rain, snow and dew strengthens the human body and nourishes the body with vitamin D. Regular walks help.-as stated by Sebastian Kneipp, Doctor of Traditional European Medicine (TMC).
- People can create vitamin D on their own by exposing their face, neck, hands and hands to sunlight and according to the season 5 to 30 minutes a day. From spring to autumn, a sufficient amount of vitamin D can be created and burns do not appear. This supply of vitamin D is retained in the body for months.
- A small amount of vitamin D can be obtained through diet, but this possibility should still be used. Sources of vitamin D are fatty fish (herring, mackerel, salmon), egg yolks, avocados, mushrooms, beef liver.
- Medical experts recommend taking smaller weekly doses of this vitamin / supplement. It is assumed that higher doses cannot be absorbed into the body at all. Doctors should give advice / guidance and the prescribed and sufficient amount for each individual to avoid an overdose of vitamin D.
