Taking care of one’s health is a priority for UK residents, especially during the long winter months when sunlight is scarce. However, a recent warning from the NHS and several nutrition experts highlights a worrying phenomenon: toxicity linked to excessive supplementation. While Vitamin D is essential for our bones, uncontrolled consumption can lead to serious complications.
In this article, we explore the warning signs that should prompt you to stop your supplement routine immediately to protect your body.
The Importance and Risks of the “Sunshine Vitamin”
In the UK, between October and March, ultraviolet radiation (invisible sun rays that allow the skin to produce nutrients) is insufficient to maintain adequate levels of Vitamin D. The government therefore recommends a daily dose of 10 micrograms. However, the current market offers supplements with dosages sometimes exceeding the safety limit by 12 times.
This situation has led to an increase in cases of hypercalcaemia (too much calcium in the blood due to excessive absorption), a medical condition that sometimes requires emergency hospital treatment.
1. Frequent Thirst and Urination
One of the first signs of an overdose is an unquenchable thirst accompanied by a need to urinate more often than usual. When the body accumulates too much Vitamin D, the balance of minerals and fluids is disrupted. Your kidneys then work harder to eliminate excess calcium, causing relative dehydration. If you notice these symptoms, it is advisable to return to a single 10-microgram dose and check if your fortified foods (foods with added vitamins) are not doubling your intake.
2. Digestive Issues: Nausea and Reflux
Excessive intake can irritate the gastrointestinal system. Patients often report nausea, frequent eructation (burping), or a “sour” stomach. To limit these effects, experts suggest choosing plain tablets rather than sprays or gummies, which often contain sweeteners or flavorings that irritate the gastric lining.
3. Bone Pain and Muscle Cramps
It is a paradox: while we take Vitamin D to strengthen our skeleton, an excess can cause dull aches in the bones and muscle cramps. This is due to an imbalance of electrolytes (minerals like magnesium and calcium that carry an electric charge necessary for muscle function). Increased hydration and a diet rich in potassium can help stabilize these symptoms.
4. Brain Fog and Headaches
If you struggle to concentrate or suffer from unusual cephalalgia (headaches) after starting a supplement course, your dosage may be too high. Cholecalciferol (the active form of Vitamin D3 found in supplements) can, in high doses, interfere with cognitive functions by raising serum calcium levels too sharply.
How to Manage Consumption Safely
The key lies in vigilance. It is crucial to audit all products you consume: multivitamins, sprays, and enriched food products. To avoid any risk, convert International Units (IU) to micrograms (simply divide by 40). If the total sum exceeds public health recommendations, it is time to simplify your routine.
