Five signs you’re taking too much vitamin D and how it could affect your health
[5 MIN READ]
Vitamin D plays a leading role in keeping you healthy. It helps your body absorb calcium and phosphorous, which is vital for maintaining strong bones and teeth. Vitamin D keeps your cells functioning correctly and helps your muscles, nerve, and immune systems perform at their best.
Vitamin D deficiency has serious consequences. Without enough, you could end up with soft bones, reduced bone mass and an increased risk of bone fractures. It’s no surprise that so many people are turning to supplements to ensure they’re getting the vitamin D they need.
Supplements are an excellent way to add to the vitamin D you get from sunlight and diet—many doctors recommend taking a daily dose. Most experts advise taking no more than 4,000 IU of vitamin D a day. Exceeding that on a regular basis, even if you are Vitamin D deficient, could produce toxic levels that damage your health.

Signs you’re taking too much vitamin D
It’s fairly rare to exceed your vitamin D needs, but how do you know when it happens? If you regularly experience two or more of the symptoms listed below, it may be time to talk to your doctor about testing your vitamin D levels and adjusting your daily supplement dose.
- Change in your skin tone
- Constant headache
- Excessive fatigue
- Increased thirst
- Loss of appetite
- Muscle weakness
- Nausea and vomiting
Does it matter?
If you take supplements, be aware that more does not always equal better. When you have more vitamin D than you need, it can have a negative effect on your health. You may experience one or more of the following conditions.
1. High calcium levels
Vitamin D improves your body’s ability to absorb calcium. With too much Vitamin D, your blood calcium levels can rise to dangerous levels, causing nausea, vomiting, and stomach pain. You may also experience excessive thirst and need to urinate more frequently.
2. Bone loss
If excess vitamin D causes your blood to have too much calcium, it can lead to low vitamin K levels. This affects your body’s ability to bind with calcium and use it effectively. Brittle bones, bone pain, and bone loss are all possible results.
3. Organ damage
Excess calcium can bind with phosphates in your blood and form crystals that collect in your body’s soft tissues. In severe cases, it can lead to permanent kidney and lung damage.
When you have too much vitamin D, your kidneys have trouble concentrating your urine. When this happens, the extra urine they produce will have you spending an extreme amount of time going back-and-forth to the bathroom. If that goes on too long, you’ll lose too much fluid and electrolytes and could be prone to dehydration.
5. Heart issues
Too much calcium in your blood affects your heart’s ability to function as it should. Irregular heartbeats, chest pain, dizziness, and high blood pressure may be the final outcome if it is not corrected.
