Warning: 4 common vitamins no one told you become toxic if you take too much !!!

Some individuals subscribe to the thought that, “if a little is a good thing, a lot is better.” That may be true in some activities and some circumstances when it comes to your health, but with optimal vitamin intake and supplementation that’s simply not true. The majority of people consider vitamins safe, and that belief alone can increase the likelihood of taking too many, as there is no perceived risk in the minds of many people. The truth is, too much of certain vitamins can lead to a vitamin overdose, which can be dangerous and, in some cases, life threatening.

What Vitamins Are Toxic?

Vitamins are divided into two primary groups: water-soluble and fat-soluble. Those that are water-soluble (B vitamins and vitamin C) are easily flushed from the body by means of the kidneys and are not likely to build up to cause an excess. However, high intakes might cause intestinal problems such as indigestion (e.g., vitamin C), nausea (e.g., vitamin B3) or bowel looseness (e.g., vitamin B5) so you still have to adhere to recommended intakes.

The fat-soluble vitamins are the main ones to be wary of – vitamins A, D, E and K. These are stored in the liver and can accumulate to poisonous levels when intakes are too high.

In both the US and EU, the day-to-day tolerable upper consumption level from both food and supplements combined is 3,000 mcg (10,000 IU) per day. Postmenopausal females might be recommended to limit their consumption to 1500 mcg to prevent bone demineralisation. Only go beyond these quantities under medical supervision.

The safest way to get vitamin A remains in the kind of combined carotenoids – plant pigments (eg alpha and beta carotene) which can be transformed into vitamin A in the body when required.

Your vitamin D status can be determined in an easy blood test to determine circulating levels of a non-active pro-vitamin called 25-hydroxyvitamin-D (picked since it is fairly stable). Even here, the maximum level is controversial, with some specialists suggesting higher readings than others. In general, however, I analyze levels as follows:.

– 20 – 32 ng/ml (50 – 80 nmol/L) is adequate for lots of, however not for everybody.
– Above 32 ng/ml (> 80 nmol/L) is maximum for the majority of people.
– Above 50 ng/ml (> 125 nmol/L) there is an increasing danger of toxicity.
– Toxicity is almost specific with blood levels of 60 ng/ml (150nmol/L) or above.

These are really much a minimum to avoid vitamin D deficiency, however.

Many professionals recommend that, in the lack of exposure to sunshine, an intake of 25 mcg (1000 IU) is more appropriate for optimal health. Older individuals may need more as they are less able to make vitamin D in the skin and soak up less from their diet.

One US study discovered, for example, that a consumption of 100 mcg (4000 IU) is needed to preserve vitamin D levels in all older females.

Vitamin D might be provided in higher doses, under medical guidance, to treat an extreme shortage.

  • 3. Vitamin E
