Vitamin B3 - the dementia vitamin - niacin

Depressions, Dementia …
Vitamin B3 deficiency is associated with disorders of the central nervous system. The result can be states of confusion and hallucinations. In applied nutritional medicine, vitamin B3 is therefore used successfully for psychological disorders such as depressions, dementia or schizophrenia. Vitamin B3 is also used in the treatment of allergies, asthma and acne rosacea.
In various studies it could be proven that vitamin B3 influences the blood lipids positively. It lowers the bad LDL cholesterol about 23 %. At the same time it elevates the good HDL cholesterol about remarkable 33 %. The more HDL is present in the blood, the better it is for the blood vessels. Additionally vitamin B3 lowers the lipoprotein a about 33 %. Lipoprotein a is a main risk factor for the appearance of heart attacks. Also triglycerides may be lowered about 30 – 50 % with vitamin B3.
A good sleep…
Our body is able to produce vitamin B3 itself. For this he needs the amino acid tryptophan. Tryptophan is also responsible that the resting hormone serotonin and the sleeping hormone melatonin may be produced. If now our body needs much tryptophan for the production of vitamin B3, he has no more enough to produce the hormones that are responsible for sleeping well. Sleeplessness, agitation, aggressiveness, depressions and anxiety may be a consequence. That means: enough vitamin B3 and an amino acid-rich nutrition boost the serotonin and melatonin production – for a recreative sleep.
Vitamin B3 should be taken as inositol nicotinate. This is a modified form of niacin. Pure niacin can cause erythema. Niacin is absorbed best if it is taken together with other B-vitamins during the meals. Also chromium assists the absorption of vitamin B3. Alcohol, tea, coffee, the birth control pill together with antibiotics and L-dopamine, which is used in the treatment of Parkinson-patients, are estimated to be vitamin B3 robbers.
Paticularly elder people and those, who are hectic and move very much, should take care of a sufficient vitamin B3 supply. The following symptoms may indicate a vitamin B3 deficiency: mouth ulcers, dry skin, nausea, gingival inflamations, headache, lack of appetite, huffiness or sensitiveness to bright light. Additionally a vitamin B3 deficiency can cause skin mutations.
If you suffer from gout, you should do without the additional taking of vitamin B3.
