Higher vitamin D levels appear to be associated with higher total cholesterol levels and higher HDL cholesterol levels, according to a new study presented at the American College of Cardiology's (ACC) 65th Annual Scientific Sessions.
A study of the short-term effects of taking vitamin D supplements reported that doing so increased levels of LDL, or “bad,” cholesterol.
The verdict, according to the National Institutes of Health , is that there's insufficient evidence to determine any relationship between your vitamin D intake and your cholesterol levels.
Niacin is an important B vitamin that may raise levels of high-density lipoproteins (HDL), the "good" cholesterol, and lower triglycerides. Niacin has long been used to lower triglycerides and to increase high-density lipoprotein (HDL) cholesterol.
In clinical trials, vitamin D supplementation has been reported to reduce serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) but not high-density lipoprotein cholesterol (HDL-C).
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. Remember, if you have Questions, Consult Your Pharmacist.
Some behaviors or conditions can cause sudden increases in blood cholesterol. This includes high coffee intake, rapid weight loss, cigarette smoking, and psychological stress. Being pregnant and taking certain medications, such as antihypertensive drugs, can also quickly increase cholesterol.
High cholesterol is when you have too much of a fatty substance called cholesterol in your blood. It's mainly caused by eating fatty food, not exercising enough, being overweight, smoking and drinking alcohol.
You might be given a TC:HDL ratio, which is the ratio of HDL compared to the total cholesterol. If not, you can work it out from your HDL and total cholesterol numbers. This should be as low as possible. Above 6 is considered high.
Soluble fiber can reduce the absorption of cholesterol into your bloodstream. Soluble fiber is found in such foods as oatmeal, kidney beans, Brussels sprouts, apples and pears. Add whey protein. Whey protein, which is found in dairy products, may account for many of the health benefits attributed to dairy.
Magnesium has been reported to decrease total serum cholesterol, low density lipoprotein, and very low density lipoprotein, and increase high density lipoprotein.
Taking a multivitamin with vitamin D may help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.
Oatmeal, oat bran and high-fiber foods
Soluble fiber is also found in such foods as kidney beans, Brussels sprouts, apples and pears. Soluble fiber can reduce the absorption of cholesterol into your bloodstream. Five to 10 grams or more of soluble fiber a day decreases your LDL cholesterol.
Although there are popular myths that taking fish oil lowers your cholesterol, it does not. It will lower your triglycerides, may modestly raise your HDL (which is a benefit), but can actually raise your LDL (bad) cholesterol, which is not a benefit.
If you've been prescribed high-dose vitamin D, work closely with your doctor to monitor your blood levels. It can take three months or more to bring them back up, but once they're good, you can stop the high doses and return to a lower vitamin D supplement for maintenance.
The effect of equivalent oral doses of vitamin D3 600 IU/day, 4200 IU/week and 18,000 IU/month on vitamin D status was compared in a randomized clinical trial in nursing home residents. A daily dose was more effective than a weekly dose, and a monthly dose was the least effective.
Types of Cholesterol
Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
As a guide, health authorities recommend cholesterol levels should be no higher than 5.5 mmol per litre if there are no other risk factors present, or LDL levels less than 2 mmol/l for those who smoke, have high blood pressure or pre-existing heart disease.
Total Cholesterol: <4.0 mmol/L (Individuals at high risk) <5.5 mmol/L (General population) Low Density Lipoprotein Cholesterol (LDL): < 1.8mmol/L (Individuals at high risk) < 2.0 mmol/L (General population) High Density Lipoprotein Cholesterol (HDL): > 1.0mmol/L.
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.
What Are the Symptoms of Cholesterol Problems? A high level of cholesterol in the blood doesn't have obvious symptoms, but it can increase your risk for conditions that do have symptoms, including angina (chest pain caused by heart disease), high blood pressure, stroke, and other circulatory ailments.
There's no set time of day that's best to take vitamin D supplements. Some people say taking vitamin D supplements at night is an insomnia risk. There's no research to confirm this, but you might want to take your supplement earlier in the day if you think it's screwing with your sleep.
