Pharmacist Analysis

Ashwagandha seems to have a relatively mild anti-diabetic effect via several different mechanisms.

Studies in both people and animals have shown that ashwagandha extract can lower blood sugar levels by boosting the uptake of glucose into fat and muscle cells. The active components believed to be responsible for these effects include withaferin A and withanolide A and thus, higher content of each has been related to a stronger anti-diabetic effect.

Studies have also found that withanolides may block a digestive enzyme called alpha-glucosidase, which could slow the breakdown of carbohydrates.

This interaction between ashwagandha and other medications used for diabetes may actually have a positive outcome, as it may boost the blood sugar-lowering effect of other drugs. However, it's still important to keep an eye out for the possibility of low blood sugar levels, even though there haven't been any reports of this happening in clinical studies.

As always, be sure you let your doctor know about all the medications you are taking so you can be appropriately monitored.

Ashwagandha Overview

Ashwagandha Ashwagandha, also known as Withania somnifera, is a herb commonly used in Ayurvedic medicine. It is native to India, and is used to treat a variety of conditions, including stress, anxiety, and insomnia. Some studies have also suggested that ashwagandha may have potential health benefits for conditions such as heart disease, diabetes, and cancer. However, more research is needed. Ashwagandha is often referred to as an adaptogenic herb, which is theorized to help the body to adapt to stress.

Semaglutide Overview

  • Semaglutide is used along with a diet and exercise program to control blood sugar levels in adults with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Semaglutide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may develop if high blood sugar is not treated). Semaglutide is in a class of medications called incretin mimetics. It works by helping the pancreas to release the right amount of insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. Semaglutide also works by slowing the movement of food through the stomach.

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Using medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
