A new study from Urmia University of Medical Sciences has found that turmeric and vitamin D might help people with type 2 diabetes manage their blood pressure.
Turmeric is a bright yellow spice often used in cooking, especially in Asian countries. It contains active compounds called curcuminoids, which have long been used for their healing properties.
Vitamin D is another important nutrient that we get from food and sunlight. It helps keep bones strong and plays a role in how our bodies use calcium and phosphorus.
Past research has shown that both curcuminoids and vitamin D can reduce inflammation, support the immune system, and even slow the growth of some cancer cells. But we still don’t know much about how they affect blood pressure—especially in people with type 2 diabetes.
In this study, scientists worked with 80 people who had both type 2 diabetes and low levels of vitamin D. They divided them into four groups. One group got curcuminoids, one got vitamin D, one got both, and one got a placebo (a pill with no active ingredients). They followed these groups for 12 weeks and checked their blood pressure before and after the treatment.
The results were interesting. People who took vitamin D saw a drop in both their top (systolic) and bottom (diastolic) blood pressure numbers. Those who took curcuminoids mainly saw a drop in the bottom number (diastolic). When people took both, curcuminoids seemed to help with diastolic pressure but may have slightly reduced vitamin D’s effect on systolic pressure.
This shows that these two supplements affect blood pressure differently. It also means we need more research to understand how they interact.
If you’re wondering where to get these nutrients, curcuminoids are found in turmeric, curry powder, and foods made with curry. Vitamin D is found in fatty fish like salmon and sardines, canned tuna, egg yolks, mushrooms, and foods that have vitamin D added to them, like milk and cereals.
For people with type 2 diabetes, this study is hopeful. It suggests that natural supplements like turmeric and vitamin D could help control blood pressure. However, it’s important to remember that more studies are needed. We still need to learn how much to take and how best to combine them.
If you have diabetes, talk to your doctor before starting any new supplement. Managing blood pressure is important to lower the risk of heart disease, stroke, and other problems. That usually involves medicine, eating well, staying active, and managing stress.
This study also reminds us that natural remedies may be part of the solution. Other studies have shown that foods like pomace olive oil, honey, and blueberries can also help with health issues related to diabetes. The common diabetes drug metformin has even been linked to better brain health.
This research, led by Shirin Ebrahimkhani, was published in the journal Clinical Nutrition ESPEN. It adds to the growing list of ways natural supplements might help people with type 2 diabetes live healthier lives.
