Vitamin D overdose. Expert opinion. Check it out!

Interest in vitamin D is growing. We supplement it because "there is not enough sunshine in Poland". Consuming it on our own without control can have unpleasant health and... financial consequences.

Together with nutritionist Marta Kaczorek, we will explain to you what a vitamin D overdose is, how to prevent it and what a healthy, sensible supplementation is.

Can you overdose on vitamin D?

.

Yes, it is possible to overdose on vitamin Dand. Overdosing occurs due to over-supplementation. However, let me reassure you - this is a very rare situation. Studies show that taking 60 000 international units (IU) vitamin D daily for several months can cause toxicityand.

An overdose is also referred to as vitamin D hypervitaminosis, vitamin D toxicity or vitamin D poisoning. While it is difficult to get to this critical state, it does not mean that we can supplement this vitamin without common sense.

How to prevent an overdose? Advice from a nutritionist

.

As nutritionist Marta Kaczorek says, it is the quality of supplementation that matters, not the quantity of supplement taken. We understand quality by:

• selecting a supplement in the best possible form of absorption for us,

  .

• Taking an individual dose for our needs with a doctor or pharmacist,

• .

• systematic supplementation,

  .

.

Safe supplementation - that is, how much?

.

For vitamin D to reach toxic or dangerous levels in the body, it must exceed 100 nanograms (ng) per mland. Fortunately, toxicity is unlikely if you control your daily intake and avoid excessive supplementation. Experts recommend that people with typical vitamin D levels should not exceed 2000 IU per day .

Did you know that in spring and summer, 15 minutes of sun exposure, between 10am and 3pm with arms and legs uncovered, will give you as much as supplementation with 2000 IU of vitamin D ?

.

I'll take more... yes in case you need it!

.

"Another source of vitamin D for young children is breast milk or modified milk. Modified milk of about 500 ml/day already covers the child's daily requirement. And this can already be the 3rd source of vitamin D for our baby", adds the nutritionist.

.

Parents should be alert to any supplementation in their child, as well as their diet. We have more and more vitamin D-fortified products on the market (drinks, snacks) and we can lose track of the daily dose. If we do not overdose, we are simply throwing money down the drain on unnecessary supplementation.

There is no sunshine in Poland

.

Listening to many stories among family and friends, I have noticed that we like to experiment with the dosage of medicines and supplements on our own. "Vitamin D? You have to take a lot because there is no sunshine in Poland!" - I once heard from a close friend. It's true that we have a problem with lack of sunshine in autumn and winter, but that doesn't mean that four drops or one more tablet will be a good choice.

"Supplements don't work anyway, so I take, as a rule, times two so that anything gets absorbed" - another quote, also heard at a social gathering.

.

Vitamin D for animals...for humans? 

.

In July 2022, a woman overdosed on vitamin D by using excessive amounts of a dietary supplement intended for horses.

She was using vitamin D in a combination formulation with K2 MK7 at a dose of 50,000 IU per day. She added fuel to the fire by also supplementing with large amounts of calcium. She survived, but was in very poor condition.

Reading about this unfortunate event, I came across many articles and comments from people who ridiculed vitamin D overdosing. And this is still the case for horses! As the above case and many others show - you can.

.

This case may seem ridiculous and funny to some, but the victims of hypervitaminosis are often older people. Such as our parents or grandparents. We should educate each other and explain what healthy supplementation is all about. 

Today, ask your loved ones what they are supplementing and in what dose. Perhaps unnecessarily? Maybe too much?

We hope you can see from this article on vitamin D overdose that it is just one of many vitamins we can overuse. Take care of yourself. Get yourself examined. Do a review of medications, supplements, enrich your diet. Spend time being active, outside. Let the sunshine bathe you.

Are you supplementing with vitamin D? Or do you know someone who likes horse doses of vitamin D? Write me in the comments, I'm curious.
