Vitamin D overdose - symptoms and effects

Causes of a vitamin D overdose

According to many experts, the risk of overdosing on vitamin D through natural sources (i.e. sunbathing or a balanced and varied diet) is really low. A much more frequent cause of excessive cholecalciferol levels in the body is an incorrect supplementation - the use of products rich in vitamin D, which is available in a poorly assimilated form, may result in taking excessive portions.

Therefore, when deciding to use dietary supplements, it is much better to reach for products containing an optimal amount of the active substance. The Olimp Sport Nutrition brand recommends the Gold Vit D3+K2 Sport Edition - capsules that enrich the daily diet with appropriately determined portions of essential vitamins for maintaining a favourable condition of the musculoskeletal system and the calcium-phosphate balance. The product is easy to use, contains raw materials subjected to microbiological purity analysis and meets the necessary standards related to safety during use.

What symptoms indicate an overdose of vitamin D?

Symptoms indicating an overdose of vitamin D may be difficult to identify clearly at first sight. The initial symptoms include a lack of appetite, strenuous constipation, vomiting, sleeping problems, itching, excessive and sometimes even uncontrolled urination or increased thirst. Over time, neuromuscular problems may occur, which may be manifested by an excessive irritation, hyperactivity or a decrease in muscle tension. In addition to these conditions, an overdose of vitamin D can cause symptoms such as:

• Chronic hypertension
• More or less intense renal failure
• Pathological enlargement of the liver or spleen size
• Excessive build-up of calcium deposits in internal organs and blood vessels

It should not be forgotten that the risk of overdosing on vitamin D affects not only adults! Children may also be at risk because of an oversupply of cholecalciferol. Pregnant women must remember that too high a concentration of vitamin D can lead to the development of real deformities of the skeletal system of the forming foetus.

What should be done to mitigate the effects of a vitamin D overdose?

Optimal health allows the body to regulate the level of vitamin D , which is one of the elements of prevention of poisoning by overdosing. However, if the first effects of an oversupply of cholecalciferol have already occurred, the best way to do so will be to discontinue the current use of dietary supplements. Moreover, it is worthwhile to consult your own observations and symptoms with your doctor, who will help to determine whether you are hypersensitive to vitamin D.
