An overdose of vitamins

Is it possible to overdose on vitamins?
Recently we often hear about the controversial vitamins.
Some recommend taking vitamins in large quantities, while others say that vitamins are toxic in large quantities.
The answer is that everything in excess can be toxic.

You can die from excessive water intake. Large amounts of air can cause hyperventilation. You can burn off excessive sun exposure.
Even the healthiest thing in excess can have negative effects on health. Almost all nutrients are toxic in excess.
Of course, you do not want to spend all day chewing and swallowing vitamins. In particular, no synthetic vitamins, produced by pharmaceutical companies.
When you buy vitamins, always choose the vitamins made from natural ingredients, from fruits and vegetables, and natural dietary supplements based on herbs and super foods.
With these vitamins are almost impossible to overdose. Only if you do it deliberately.
So the answer to this question is that, theoretically, you can overdose on the vitamins.
But natural vitamin toxicity threshold is ten times greater than the threshold toxicity of synthetic drugs.

Two types of vitamins and their toxicity

There are two types of vitamins - vitamins are water soluble and fat-soluble vitamins.
The category of water soluble vitamins including B group vitamins and vitamin C.
These vitamins are easily absorbed through the gastrointestinal tract into the blood and accumulate in the body.These vitamins are quickly eliminated from the body, because it needs their daily intake.
Because of their rapid elimination from the body, it is almost impossible to overdose on vitamins B and C.
Fat-soluble vitamins have different properties. They are stored in fatty tissues and liver and is slowly eliminated from the body.
This group includes vitamins A, D, E and K. Excessive intake of these vitamins can lead to their deposition in the body and health problems.

Vitamin A
Vitamin A - or retinol - plays an important role in the body. Vitamin A is mainly in products of animal origin.
Beta-carotene - an antioxidant that the body converts into vitamin A, can be found in fruits and vegetables.
The recommended daily intake of vitamin A is up to 10,000 IU, and beta-carotene - from 25000 to 83 000 IU per day. For the purpose of treatment is possible the intake of larger amounts of vitamin A and beta-carotene, but only by the doctor.

Vitamin D
If you spend enough time in the sun, you do not have to worry about vitamin D, because it creates in our bodies when we are exposed to sunlight.
You can not overdose with vitamin D - because our bodies produce exactly as much as necessary.
If you do not get enough sunlight, you can make vitamin D in supplement form. The recommended dose is up to 10,000 IU per day.
Sometimes the purpose of treatment using higher doses of this vitamin (up to 50 000 IU), but only if recommended by your doctor.

Vitamin E
Vitamin E is a powerful antioxidant. It is important for the immune system, endocrine system and reproductive organs.
We find it in vegetable oils, nuts, leafy vegetables and avocados.
Normal diet get enough of this vitamin. If you choose to enter additional amounts of vitamin E, do not exceed a dose of 1000 IU per day.

Vitamin K
In nature there are two forms of vitamin K: vitamin K1 (which we take with food) and vitamin K2 (which is synthesized by bacteria in the small intestine).
Natural sources of vitamin K are green leafy vegetables, parsley, avocado, olive oil and algae.
Healthy man does not lack vitamin K, but if for some reason you must take, the recommended dose is 150 micrograms a day.

Vitamins against disease
Natural vitamins are a great way to prevent and treat many diseases.
Many nutritionists and alternative health problems in doctors will recommend taking a combination of certain vitamins, minerals in food supplements. And it really works.
Vitamins are safe, efficient and have reasonable prices, if you compare them with the costs, by the disease.

Unfortunately, in the average diet of modern man lacks many vitamins and minerals.
Taking natural supplements is a great way to enter the necessary amount of nutrients in your body.
