Headache vitamin

Of the water-soluble vitamins, intakes of nicotinic acid [59-67-6] on the order of 10 to 30 times the recommended daily allowance (RE)A) have been shown to cause flushing, headache, nausea, and moderate lowering of semm cholesterol with concurrent increases in semm glucose. Toxic levels of foHc acid [59-30-3] are ca 20 mg/d in infants, and probably approach 400 mg/d in adults. The body seems able to tolerate very large intakes of ascorbic acid [50-81-7] (vitamin C) without iH effect, but levels in excess of 9 g/d have been reported to cause increases in urinary oxaHc acid excretion. Urinary and blood uric acid also rise as a result of high intakes of ascorbic acid, and these factors may increase the tendency for formation of kidney or bladder stones. AH other water-soluble vitamins possess an even wider margin of safety and present no practical problem (82).

There is evidence that some people are sensitive to free glutamates. These people get headaches or other symptoms if they ingest too much. This may be related to pyridoxine (vitamin B6) deficiencies, as this vitamin is necessary for glutamate metabolism. People with uncontrolled severe asthma may find that glutamates complicate or worsen their symptoms. 

There is only a limited capacity to metabolize vitamin A, and excessive intakes lead to accumulation beyond the capacity of binding proteins, so that unbound vitamin A causes tissue damage. Symptoms of toxicity affect the central nervous system (headache, nausea. 

PPIs are usually well tolerated. Potential adverse effects include headache, dizziness, somnolence, diarrhea, constipation, nausea, and vitamin B12 deficiency. All PPIs can decrease the absorption of drugs such as ketoco-nazole or itraconazole that require an acidic environment for absorption. Other drug interactions vary with each agent. 

Fish Liver Poisoning. The livers of large fish species such as sharks, tunas, and sea bass may cause intense headaches, vomiting, facial edema, fever, and severe desquamation. Onset of symptoms is from 30 minutes to 12 hours. All of these fishes contain extremely high levels of vitamin A in their livers. As the fish grows, the concentration of vitamin A in the liver increases (94-96). ... 

Prolonged administration of large dosages of vitamin E may result in muscle weakness, fatigue, headache, and nausea. This toxicity can be reversed by discontinuing the large-dose supplementation.

Gastrointestinal complaints (eg, nausea, diarrhea, vomiting, flatulence) are the most common adverse effects but rarely require discontinuation of therapy. Other potential adverse effects include headache and asthenia. Tenofbvir-associated proximal renal tubulopathy causes excessive renal phosphate and calcium losses and 1-hydroxylation defects of vitamin D, and preclinical studies in several animal species have demonstrated bone toxicity (eg, osteomalacia). Monitoring of bone mineral density should be considered with long-term use in those with risk factors for or with known osteoporosis, as well as in children. Reduction of renal function over time, as well as cases of acute renal failure and Fanconi s syndrome, have been reported in patients receiving tenofovir alone or in combination with emtricitabine. For this reason, tenofovir should be used with caution in patients at risk for renal dysfunction. Tenofovir may compete with other drugs that are actively secreted by the kidneys, such as cidofovir, acyclovir, and ganciclovir.

A lack of lipid-soluble vitamins can be detrimental, but so can excessive amounts, particularly of vitamins A and D, which can accumulate to dangerous levels. Too much vitamin A causes dry skin, irritability, and headaches. Excessive amounts of vitamin D lead to diarrhea, nausea, and calcification of joints and other body parts. Vitamins E and K are less harmful in large quantities because they are readily metabolized.

Be cautious about overdosing on dietary supplements. Large doses of some nutrients act as drugs and prolonged heavy use can reach toxic levels. For example, too much Vitamin A can cause headaches, nausea, and diarrhea. High doses of Vitamin D can cause kidney damage. Too much iron can harm your liver. 

Vitamin D is a fat-soluble vitamin, and excessive doses can accumulate in the body, leading to toxicity. Some early signs of vitamin D toxicity include headache, increased thirst, decreased appetite, metallic taste, fatigue, and gastrointestinal disturbances (nausea, vomiting, constipation, or diarrhea). Increased vitamin D toxicity is associated with hypercalcemia, high blood pressure, cardiac arrhythmias, renal failure, mood changes, and seizures. Vitamin D toxicity is a serious problem that can cause death because of cardiac and renal failure. 

Vitamin B3 is a pyridine compound found in fish, meat, liver, cereal husks, nuts, and pulses. Niacin deficiency produces pellagra, which manifests as dermatitis, diarrhea with enteritis, nausea and vomiting, dementia with headache, insomnia, loss of memory, and disturbances of motor and sensory neurons. Anemia and hypoprotcincrnia are common in pellagra chronic alcoholics have more tendency to suffer from pellagra. Com eaters suffer from pellagra because com... 

Intoxication with vitamin D causes weakness, nausea, loss of appetite, headache, abdominal pains, cramps, and diarrhea. More seriously, it also causes hypercalcemia, with plasma concentrations of calcium between 2.75 to 4.5 mmol per L, compared with the normal range of 2.2 to 2.5 mmol per L. At plasma concentrations of calcium above 3.75 mmol per L, vascular smooth muscle may contract abnormally, leading to hypertension and hypertensive encephalopathy. Hypercalciuria may also result in the precipitation of calcium phosphate in the renal tubules and hence the development of urinary calculi. Hypercalcemia can also result in calcinosis - the calcification of soft tissues, including kidneys, heart, lungs, and blood vessels. This is assumed to be the result of increased calcium uptake into tissues in response to excessive plasma concentrations of the vitamin and its metabolites. 

Studies during the 1960s showing thatvitaminBg supplements were effective in overcoming some of the side effects of (high-dose) oral contraceptives have led to the use of vitamin Bg in treatment of the premenstrual syndrome - the condition of nervousness, irritability, emotional disturbance, headache, and/or depression suffered by many women for up to 10 days before menstruation.

A variety of antioxidants are added to food including vitamin C and vitamin E. Two antioxidants that may occasionally cause problems are butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), which have been associated with symptoms such as eczema, skin rash, runny nose, wheezing, headache, chest pain, flushing of the skin, and red eyes. At the same time, it has been reported that these antioxidants may be helpful in preventing cancer, possibly by removing damaging free radicals such as reactive oxygen and its by-products from fatty acids.
