Alternatively, taking high doses of non-synthetic vitamin K seems to be relatively harmless, which is why an upper intake level UL has not been set for this nutrient 6.
Water-soluble vitamins are readily excreted from the body, while fat-soluble vitamins can be stored in tissues. Fat-soluble vitamins are more likely to cause toxicity, although water-soluble vitamins can do so as well.
When consumed naturally through foods, these nutrients are unlikely to cause harm, even when consumed in large amounts. When taken in excess, some water-soluble vitamins can cause adverse effects, some of which can be dangerous. However, similarly to vitamin K, certain water-soluble vitamins have no observable toxicity and hence no set UL.
These vitamins include vitamin B1 thiamine , vitamin B2 riboflavin , vitamin B5 pantothenic acid , vitamin B7 biotin , and vitamin B12 cobalamin 9 , 10 , 11 , 12 , Therefore, caution should be taken with all nutritional supplements. The following water-soluble vitamins have set ULs, as they can cause adverse side effects when taken in high doses:.
Note that these are side effects that healthy people may experience when taking large doses of these vitamins. Individuals with health conditions can experience even more serious reactions to taking too much of a vitamin. For example, though vitamin C is unlikely to cause toxicity in healthy people, it can lead to tissue damage and fatal heart abnormalities in those with hemochromatosis , an iron storage disorder Aside from vitamin K, which has a low potential for toxicity, the remaining three fat-soluble vitamins have a set UL due to their potential to cause harm at high doses.
Although vitamin K has a low potential for toxicity, it can interact with certain medications, such as warfarin and antibiotics 6. Both water- and fat-soluble vitamins can cause side effects when taken in high doses, with some causing more severe symptoms than others. For example, hypervitaminosis A can be caused by taking one large dose of over mg of vitamin A, or chronic use of more than 10 times the recommended daily intake Vitamin A toxicity may lead to serious complications, such as increased spinal fluid pressure, coma, and potentially fatal organ damage Additionally, taking megadoses of vitamin D — more than 50, IU daily — over long periods can lead to high blood levels of calcium hypercalcemia , which can lead to death Overdosing on other vitamins can likewise cause potentially fatal side effects, such as liver damage.
A case report found that taking very high doses of over 5 grams of extended-release niacin can lead to metabolic acidosis, a buildup of acid in body fluids, as well as acute liver failure — both of which can be fatal Keep in mind that these potentially deadly side effects are associated with taking exceptionally high doses of vitamins.
Even so, caution should always be taken when consuming any dietary supplement. The best way to get the nutrients you need is by consuming a well-rounded diet. However, many people need to supplement with vitamins for a variety of reasons. These include:. While there's no upper limit to how much vitamin B12 you can take, there are general dosage recommendations. For example, the Vegetarian Nutrition Dietetic Practice Group recommends that vegans consider supplementing with mcg of B12 per day.
Before starting any kind of supplement, talk with your doctor or a registered dietitian about your diet and health history to determine what supplements you might need and how much you should take.
Side effects from B12 supplementation are rare, but possible when receiving B12 injections. Some people may need B12 supplementation due to certain conditions that inhibit absorption. Talk with your doctor or a registered dietitian about whether or not you should supplement with B12 and how much you should take.
