Healthcare professionals warn against Vitamin D use if you notice these four specific symptoms.
During the winter months, when sunlight is scarce, health experts often recommend vitamin D supplements to help maintain bone and muscle health.
An NHS spokesperson previously explained, “From October to March, we can’t synthesize enough vitamin D from sunlight. To support your bones and muscles, a daily supplement of 10 micrograms of vitamin D is advisable, available at most pharmacies and retailers.”
Due to the reduced sunlight during these months, adults are encouraged to take a daily vitamin D supplement. However, it is crucial to avoid excessive intake, which may lead to adverse effects.
If you experience any of the following four symptoms, you should consider stopping your Vitamin D consumption (according to the Mirror).
Nausea, Burping, or Stomach Upset
Experiencing nausea or stomach discomfort after taking supplements can be quite unpleasant. It’s advisable to take your dose with a meal. If you find that sprays or gummies are causing these issues, switching to standard tablets—ideally taken after experiencing any symptoms—may be a better option.

Many of these complications occur because sprays contain sweeteners that may irritate your digestive system, an issue less common with standard tablets.
Increased Thirst and Frequent Urination
According to the Mirror, excessive Vitamin D intake can disrupt your body’s fluid and salt balance, resulting in increased bathroom visits. It’s certainly inconvenient—especially after arriving at work in the morning.
Consistent thirst and frequent urination may indicate that you are consuming too much vitamin D.
Cognitive Confusion
You might expect vitamin D to alleviate headaches and brain fog, but an overdose can lead to the opposite effect, causing these very symptoms.

If you’re experiencing cognitive difficulties, consider opting for a simple 10-microgram D3 tablet instead of gummies, which might cause problems.
Muscle and Bone Pain
Frequent muscle and bone aches after taking Vitamin D supplements should serve as a warning sign.
To alleviate these uncomfortable symptoms, it is important to stay hydrated and consume foods rich in essential minerals. Additionally, reducing your Vitamin D intake can help mitigate these effects.
Medical Guidance
Regarding these symptoms, Biomedical scientist Tobias Mapulanga stated: “Nausea, persistent thirst, frequent urination, stomach pain or constipation, headaches or brain fog, and new aches or cramps often arise after increasing vitamin D intake or incorporating supplements like sprays or gummies—this suggests the supplement is not working as intended.”
In conclusion, while Vitamin D is essential for overall health, moderation is key. Awareness of the signs that indicate excessive intake is crucial to avoid complications and maintain well-being during the winter months.
