Does vitamin D spike blood sugar?

Vitamin D supplementation may help lower average blood sugar levels in people with type 2 diabetes; and is especially effective in people who also have a vitamin D deficiency, and are non-obese and deficient. Supplementation for more than 12 weeks at ≥ 1000 IU/day may be most beneficial.


Can vitamin D raise blood sugar levels?

Intake of vitamin D supplements led to a marginally significant decrease in fasting blood glucose [FBS: −12 (4) in the intervention group compared to − 3 (2) in the control group; P = 0.055].

How does vitamin D affect diabetes?

Evidence indicates that vitamin D treatment improves glucose tolerance and insulin resistance. Vitamin D deficiency leads to reduced insulin secretion. Supplementation with vitamin D has been shown to restore insulin secretion in animals.


How much vitamin D should diabetics take?

“The standard dosage is 400 IUs per day, but for those with diabetes, the current recommended safe daily dose to maintain optimal vitamin D levels is 1,000 to 2,000 IUs per day.”

Does vitamin D spike insulin?

Vitamin D reduces insulin resistance probably through its effect on calcium and phosphorus metabolism and through up regulation of the insulin receptor gene [13]. One study on 5,677 subjects with impaired glucose tolerance showed that vitamin D supplementation increased insulin sensitivity by 54% [14].


Vitamin D and Diabetes: What We Learned From the D2d Trial



Does vitamin D affect A1c?

After adjusting for age and BMI, we found no significant association between the levels of vitamin D and HbA1c (P = 0.626).

What vitamin increases blood sugar?

Niacin raises fasting glucose levels (your blood sugar levels when you are not eating) for people with diabetes, meaning the risks may outweigh the benefits. And while niacin can raise HDL cholesterol, there's no evidence that this leads to a lower risk of cardiovascular disease.

When is the best time to take vitamin D?

Try taking it alongside breakfast or with a bedtime snack — as long as it doesn't interfere with your sleep. The key is to find what works for you and stick with it to ensure you're meeting your vitamin D needs.

Can low vitamin D cause high sugar?

Vitamin D deficiency has been linked to prediabetes, which is a blood glucose, or sugar, level that is too high but not high enough to be considered diabetes.


What are the signs of to much vitamin D?

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.

Does vitamin D reduce diabetes?

As described above, vitamin D is thought to improve insulin resistance and promote insulin secretion. Therefore, clinical trials often use outcomes such as homeostasis model assessment of insulin resistance, fasting plasma glucose levels, and hemoglobin A1c levels.

Does D3 lower blood sugar?

Vitamin D supplementation has a modest impact on A1c levels

The study saw a modest reduction in the A1c levels of the group taking D3 supplementation compared to the placebo group, but no noticeable changes in their fasting blood sugar levels.

So people reduce their carb intake, go on a low carbohydrate diet, and focus on eating healthy fats and (in many cases) too much protein. But what this solution crucially fails to address is insulin resistance, which is the true cause of those high blood glucose numbers.

What causes your A1C to go up?

High A1c is caused by having an elevated blood sugar level over a period of three months. According to the NIH, the most common high A1c causes and risk factors include diabetes, anemia, lack of exercise, and obesity.
