Holy Basil

Holy basil (Ocimum sanctum and Ocimum album), also known as tulsi, improves insulin release in the pancreas and reduces insulin resistance so that muscle and fat cells are better able to absorb glucose from the circulation.

Holy basil is available from Amazon UK and

Black Seed

Taking black seed can improve insulin secretion, glucose absorption and reduce excess production of new glucose in the liver.

Black seed is available from Amazon UK and


Chromium enhances the uptake of glucose into cells by increasing the movement of insulin receptors from the inside of a cell to the outer membrane. This helps to reduce insulin resistance if you are chromium deficient.
Chromium is available from Amazon UK and


Cinnamon contains unique, antioxidant polyphenols that activate insulin receptors so they respond to insulin hormone more effectively. This reduces insulin resistance, improves the uptake of glucose into muscle and fat cells, and reduces the production of new glucose in the liver. There is evidence that cassia cinnamon is more effective than Ceylon cinnamon, although this is not always easy to find.
Cinnamon is available from Amazon UK and


Magnesium is essential for at least 600 metabolic enzymes to work properly, including those involved in glucose control. Lack of magnesium is associated with insulin resistance and glucose intolerance.

Magnesium is available from Amazon UK and

CBD oil capsules

CBD (cannabidiol) oil interacts with your body’s endocannabinoid system to damp down its over stimulation. An overactive endocannabinoid system is now believed to influence the development and progression of diabetes and its complications.

Healthspan CBD capsules are available from and from


Turmeric contains curcumin which improves insulin resistance by activating insulin receptors. Turmeric also improves the release of insulin from beta-cells in the pancreas, suppresses inflammation and, as an antioxidant, helps to protect against diabetes-related complications. Most turmeric supplements are poorly absorbed. Select one that is solubilised, or which has added bioperine to boost bioavailability.

Turmeric is available from Amazon UK and

Green Tea

Green tea antioxidants reduce the absorption of dietary glucose, increase insulin sensitivity, and reduce the production of excess new glucose in the liver. They may also suppress appetite and boost fat burning to aid weight loss.

Green tea extracts are available from Amazon UK and

Alpha-Lipoic Acid

Alpha-lipoic acid improves the release of insulin from the pancreas, reduces insulin resistance, and improves glucose uptake into muscle cells by as much as 50%. As an antioxidant, alpha lipoic acid also helps protect against diabetes complications.

Alpha lipoic acid is available on Amazon UK and

Ubiquinol Coenzyme Q10

Your own production of coenzyme Q10 naturally decreases with age so that insulin secreting cells in the pancreas function at a sub-optimal level. This may contribute to poor glucose tolerance and type 2 diabetes. Ubiquinol also lowers blood pressure, reduces statin side effects and, as an antioxidant, helps protect against diabetes complications.

Ubiquinol is available on Amazon UK and


As an antioxidant, Pycnogenol protects pancreatic cells to improve insulin secretion and glucose control.

Pycnogenol pine bark extracts are available on Amazon UK and

Vitamin C

Vitamin C blocks the formation of harmful sorbitol inside cells to protect against diabetes-related complications in the eyes (retinopathy, cataracts), kidneys (nephropathy) and nervous system (peripheral neuropathy). The form known as ester-C is body-ready and non-acidic.

Vitamin C is available on Amazon UK and

Apple Cider Vinegar

Apple cider vinegar slows the breakdown of complex sugars within the gut, to regulate the absorption of glucose.

Apple cider vinegar tablets are available on Amazon UK and
