A study of the short-term effects of taking vitamin D supplements reported that doing so increased levels of LDL, or “bad,” cholesterol.
Vitamin D is linked to cholesterol because we need cholesterol in our skins cells to make vitamin D from sunlight. The vitamin D is later transformed again in the liver and kidneys, but cholesterol is needed for the first step.
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.
High stress levels are one possible cause of a sudden spike in cholesterol. When a person experiences stress, their cortisol levels increase significantly . Cortisol can also trigger the release of extra cholesterol. Therefore, when a person experiences intense stress, this can significantly raise their cholesterol.
“Over-the-counter fish oil supplements may also contain large amounts of other unwanted saturated fats, which could increase your bad cholesterol.” Over-the-counter supplements aren't regulated for quality and contents, so you don't know what you're really getting.
High cholesterol levels are considered: too high: between 5 and 6.4mmol/l. very high: between 6.5 and 7.8mmol/l. extremely high: above 7.8mmol/l.
Signs of too much vitamin D
Symptoms of vitamin D toxicity (a.k.a. hypervitaminosis D) can include a loss of appetite, weight loss, excessive urination, and heart arrhythmia. High doses of vitamin D can raise blood levels of calcium (hypercalcemia), which can damage the heart, kidneys, and blood vessels.
The average intact parathyroid hormone levels were 24.2 pg/ml (D3) vs. 30.2 pg/ml (no D3). In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe.
The takeaway. Vitamin D is an important nutrient. There's not enough evidence to say if it helps decrease cholesterol, but it's still healthy to make sure you get enough of it. You can get vitamin D through foods, supplements, or exposure from the sun.
Supplements that should be avoided include red yeast rice, garlic, sustained-release niacin, no flush niacin, and niacinamide. These supplements have no data to support their use in lowering cholesterol levels or have been associated with liver damage.
When you're deficient in magnesium, tension in the muscles of the body's blood vessels is a consequence, according to Carolyn Dean, MD, ND, author of The Magnesium Miracle. This tension, in turn, can trigger high blood pressure. Magnesium promotes reduced cholesterol levels.
How long to take it for. For adults, if you're taking a loading dose for severe vitamin D deficiency you'll usually take it daily or weekly for 6 to 10 weeks. To maintain your vitamin D levels or prevent deficiency you'll usually take colecalciferol long term.
In conclusion, vitamin D3 can be taken as a prophylactic drug for hypertension by the elderly and obese folks with vitamin D deficiency who are at high risk of hypertension. Vitamin D3 can be used as an adjuvant drug to control the blood pressure on hypertension patients with vitamin D deficiency.
Taken in appropriate doses, vitamin D is generally considered safe. However, taking too much vitamin D in the form of supplements can be harmful. Children age 9 years and older, adults, and pregnant and breastfeeding women who take more than 4,000 IU a day of vitamin D might experience: Nausea and vomiting.
But beyond blood levels of 21 nanograms per milliliter of 25-Hydroxyvitamin D — considered the low end of the normal range for vitamin D — any additional increase in vitamin D was associated with an increase in CRP, a factor linked to stiffening of the blood vessels and an increased risk of cardiovascular problems.
Low vitamin D levels could result in dyslipidemia, and lipid abnormalities—that is, an increase in triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels and a decrease in high-density lipoprotein cholesterol (HDL-C) level—have been identified as important risk factors for ...
Is too much vitamin D3 (cholecalciferol) harmful? Yes, having vitamin D levels that are too high in your body can lead to high blood levels of calcium. This can be harmful to your kidneys and cause side effects, such as nausea, constipation, loss of appetite, muscle weakness, and kidney stones.
Our only hard recommendation: Avoid supplementing with vitamin D at night. There's evidence that vitamin D can suppress melatonin—which is bad news for your sleep quality.
In addition, taking a supplement that contains too much vitamin D can be toxic in rare cases. It can lead to hypercalcemia, a condition in which too much calcium builds up in the blood, potentially forming deposits in the arteries or soft tissues. It may also predispose people to painful kidney stones.
LDL -cholesterol levels greater than 3.5 mmol/L are considered elevated for some people at low cardiovascular risk and most individuals at intermediate risk and may need behavior modifications and/or pharmacological treatment Note 5 (see About cholesterol).
Total cholesterol levels should be lower than 5.5 mmol/L, if you have no other risk factors. If you have cardiovascular risk factors such as high blood pressure, pre-existing cardiovascular (heart) disease or diabetes, or you smoke, the aim for LDL cholesterol levels would be less than 2 mmol/L.
Blood cholesterol is measured in units called millimoles per litre of blood, often shortened to mmol/L. As a general guide, total cholesterol levels should be: 5mmol/L or less for healthy adults. 4mmol/L or less for those at high risk.
