Vitamin D contains in eggs, butter, oil-rich marine fish, fish oil, and eggs, milk, cheese, cottage cheese and other dairy products, wheat, parsley. Very often dairy products and additionally enriched with vitamin D.
Symptoms of vitamin D deficiency
Poor appetite, weight loss, burning sensation in the mouth, reduced vision, insomnia, brittle hair and nails, deterioration of teeth, increased brittleness and softening of the bones (osteoporosis and osteomalacia). In children with a deficiency of vitamin D often develop rickets, so it is especially important in infancy and during pregnancy and lactation.
Symptoms of Vitamin D hypervitaminosis
Vitamin D – fat soluble, respectively, it can accumulate in the body. It is also worth bearing in mind that an excess can lead to the deposition of large amounts of calcium salts.
The most common symptoms of hypervitaminosis – poor appetite, disturbances in bowel, nausea, vomiting, weakness, joint pain, headaches and muscle pain, high blood pressure, spasms of the limbs. The food (if you do not overdo it with vitamin D fortified foods) can’t be cause of Vitamin D overdose “Overdose” is also impossible because of sunbathing. Excess ultraviolet radiation is fraught with other dangers, such as disturbances in the DNA of cells and greatly increases the risk of melanoma.
Vitamin B6, also named pyridoxine, is one of eight water-soluble B vitamins. Vitamin B6 supports more vital bodily functions than any other vitamin. Pantothenic acid is sometimes called the “anti-stress” vitamin.
Vitamin B6 is a coenzyme for several enzyme systems. Pyridoxine is required for the balancing of hormonal changes in women as well as assisting the immune system and the growth of new cells.
Vitamin B6 is not toxic when supplied by food in the diet.
Pantothenic acid supplements usually contain calcium pantothenate in tablets or capsules. Just as there’s no RDA for pantothenic acid, there’s no real overdose level.
Supplemental forms are usually in the form of pyridoxine hydrochloride. The upper limit for adults set by the Institute of Medicine is 100 mg; 100 mg per day is certainly a safe limit, well below the level that might bring on neurological problems.
Supplementation should be controlled as extreme dosage, such as in excess of 2,000 mg per day, may cause neurological damage.
Potential Pyridoxine toxicity symptoms
People on medication for Parkinson’s disease should be careful about taking Vitamin B6 as it can inactivate levodopa.
People taking pyridoxine late at night sometimes experience very vivid dreams.
Vitamin B6 can cause neurological disorders, such as loss of sensation in legs and imbalance, when taken in high doses (200 mg or more per day) over a long period of time.
Pyridoxine toxicity can damage sensory nerves, leading to numbness in the hands and feet as well as difficulty walking.
Symptoms of a pyridoxine overdose may include poor coordination, staggering, numbness, decreased sensation to touch, temperature, and vibration; and tiredness.
Some pantothenic acid is found in almost every food. Good sources are organ meats, salmon, eggs, beans, milk, and whole grains.
At least some pantothenic acid is found in every single food you eat, so there’s no way you can’t get enough. That’s good, because you need pantothenic acid for turning those foods into energy.
Pantothenic acid, in the form of coenzyme A, is needed for the synthesis of cholesterol and the synthesis of steroid hormones such as melatonin.
Most vitamins and minerals have established RDAs, guidelines that tell you the amount you need for basic good health. Pantothenic acid is an exception. It’s the first (but not the last) supplement without an RDA.
Some pantothenic acid is found in just about every food you eat, animal or vegetable
It is easily eliminated in the urine.
Oral contraceptives may increase the need for pantothenic acid. Supplements are usually in the form of pantothenol, a stable form of the vitamin. Supplements are also made from calcium and sodium D-pantothenate. The panthene form of pantothenic acid is a cholesterol-lowering drug used only under expert supervision.
Possible Vitamin B5 toxicity symptoms
It doesn’t appear to be toxic in large dosage, although diarrhea, digestive disturbances and water retention have been reported on dosage exceeding 10 g a day.
Taking 1,500 mg a day over an extended period may cause sensitivity to the teeth.
Niacin, also called Vitamin B3, works closely with all the other B vitamins, especially riboflavin and pyridoxine. We need niacin to release energy within your cells and for about 50 other body processes.
Niacin is not toxic when achieved through food. The niacinamide (nicotinamide) form of niacin has not been found to be bothersome when taken in amounts less than 2000 mg per day.
The niacinamide (nicotinamide) form of niacin has not been found to be bothersome when taken in amounts less than 2000 mg per day. Decreased insulin sensitivity and liver toxicity can result from daily amounts over 2000 mg. However, niacin in the form of nicotinic acid can cause “niacin flush” in amounts as low as 35 mg. Nicotinic acid can dilate the capillaries, causing a brief tingling and flushing of the skin.
Liver damage and aggravation of diabetes are possible dangers of such over doses. Patients with of liver disease or abnormal liver function, diabetes, peptic ulcers, gout, cardiac arrhythmias, inflammatory bowel disease, migraine headaches, or alcoholism are more susceptible to the adverse effects of excessive nicotinic acid intake. Doses of 3000 mg or more per day are potentially dangerous therapies and must be supervised.
High dosages can also cause itching, elevated blood glucose, peptic ulcers and liver damage.
Niacin (nicotinic acid) in large amounts is sometimes used to lower LDL cholesterol and triglyceride levels and to increase HDL cholesterol levels. Symptoms may include flushing and, rarely, hepatotoxicity.
The best way to avoid flushing may be to avoid nicotinic acid and take niacin in the form of inositol hexaniacinate (IHN). Doctors in Europe have been prescribing IHN for more than 30 years, but it’s only become available in the United States recently. IHN works on cholesterol just as well as nicotinic acid, but without the side effects. If you’d like to try IHN, talk to your doctor.
