Vitamin B2 (also called as riboflavin) is part of the B-complex group of vitamins. Riboflavin is produced in the body by the intestinal flora and is easily absorbed, although very small quantities are stored, so there is a constant need for this vitamin.

Vitamin B2 is required by the body to use oxygen and the metabolism of amino acids, fatty acids, and carbohydrates. Vitamin B2 is also needed to activate vitamin B6 (pyridoxine), aids to create niacin and assists the adrenal gland. It may be used for red blood cell formation, antibody production, cell respiration, and growth.

The limited capacity to absorb orally administered riboflavin precludes its potential for harm. Riboflavin intake of many times the RDA is without demonstrable toxicity.
A normal yellow discoloration of the urine is seen with an increased intake of this vitamin – but it is normal and harmless.

Potential symptoms of Riboflavin overdose

There is no known toxicity to Vitamin B2. Because Vitamin B2 is a water-soluble vitamin, excess amounts are easily excreted by the body in the urine.

Potential side effects of very high doses may include: itching, numbness, burning or prickling sensations, and sensitivity to light. Excess riboflavin excreted in the urine causes it to become bright yellow in color, which many people notice when they take B vitamin supplements.

Symptoms of Vitamin K Overdose

Vitamin K is essential for making the blood clots that quickly stop the bleeding whenever you injure yourself. Vitamin K toxicity is rare. There are three forms of vitamin K: vitamin K1, which is in foods; vitamin K2, which is made in the small intestine of the body; and vitamin K3, the synthetic form, called menadione.

Researches reported that the K3 or menadione can be toxic. In fact, the FDA has banned this synthetic vitamin K from supplements.

Currently there is no upper limit for vitamin K. There is no known toxicity with high doses of vitamin K1 or vitamin K2. One form of vitamin K, menadione (vitamin K3), is no longer used for vitamin K deficiency treatment because it may interact with glutathione, an important antioxidant.

Signs of Vitamin K toxicity

  • Excess of dose could cause excessive clotting as vitamin K helps to form clots that protect from profuse bleeding. Blood clot formation, or thrombosis, is a symptom of vitamin K toxicity.
  • Kidney Tubal Degeneration is another serious symptoms;
    If the kidneys are not functioning properly and cannot process high levels of vitamin K, it may be retained and cause K toxicity. This can lead to kidney damage, especially to the cells lining the urinary tubes.
  • Hemolytic Anemia in Infants;

Newborns have very little vitamin K in their bodies at birth. This is a danger, as any significant bleeding could cause life-threatening effects.

Best source of Vitamin K is natural food. You can easily get it from all the dark-green leafy vegetables, like kale, broccoli, and cabbage, are good choices. Strawberries are also good. Some animal foods, including egg yolks and liver, have small amounts of Vitamin K.

Symptoms Vitamin E Toxicity

Vitamin E is an useful antioxidant and one of it functions is defense the body from free radicals that may cause aging and cancer. The most well known form of vitamin E is the alpha-tocopherol, which is contented of most vitamin E supplements in the market.

Vitamin E is not toxic, but, in extreme large doses, it may impair blood clotting. The tolerable upper intake level (UL) for natural alpha-tocopherol is 1000 mg per day, about sixty-six times the RDA.

Some general practitioners recommend to stop consumption of vitamin E supplementation before surgery to decrease any risk of excess bleeding.

Premature infants are very sensitive to alpha-tocopherol supplements.
The UL for infants under one year has not been established, so supplementation of vitamin E in infants should only be attempted under the close supervision of a pediatrician.
People should not take vitamin E supplements it they take anticoagulant drugs.
People with vitamin K deficiency in diet should also avoid vitamin E supplementation to avoid the possibility of excess bleeding.

Vitamin E toxicity symptoms

Symptoms of extreme high levels of Vitamin E include: nausea, gastric problems, abdominal cramping, frequent loose stool, headache, lethargy, easy skin bruising, and prolonged bleeding.

Being a principal fat-soluble antioxidant, vitamin E is needed by every cell and artery.
Most beneficial consumption of Vitamin E is obtaining E from food.

Symptoms overdose of Vitamin D

Vitamin D is essential for healthy teeth and bones.
It is essential that vitamin D produced from sunlight on skin is almost not known to result in toxic levels. Levels of vitamin D bent from sunlight are self-adjusting.

Vitamin D toxicity is identified as hypervitaminosis D. Toxic levels of vitamin D can cause abnormally high blood calcium levels. This can result in bone loss and kidney stones. Long-term overconsumption of vitamin D can cause calcification of organs such as the heart, blood vessels, and the kidneys.
Vitamin D toxicity is impossible in healthy adults with supplement levels lower than 10,000 IU/day. The Food and Nutrition Board has established a very conservative tolerable upper intake level (UL) of 2,000 IU/day (50 mcg/day) for children and adults. The UL for infants up to one year of age is 1000 IU.

Symptoms of Vitamin D overdose

An excessive level of vitamin D occurs as a result of supplement overdose.
Having too much vitamin D in your system could leave a too elevated calcium level, a lower appetite, increased thirst, nausea, vomiting, drowsiness, abdominal pain. A long-term effect of too much vitamin D is the deposit of calcium in soft tissues of the body including the blood vessel walls and kidneys where it can cause serious damage.
