Insulin http://www.vitacost.com/science/hn/Drug/Insulin.htm

Insulin is a natural protein made by the pancreas that helps the body use sugar. Insulin is injected by all people with type 1 (insulin-dependent) diabetes mellitus and by some people with type 2 (non-insulin-dependent) diabetes mellitus to help control blood sugar levels.

Any substance (dietary, supplemental, herbal, and others) that affects blood sugar levels will directly or indirectly affect the amount of insulin required by a person with diabetes. For example, consumption of a high-fiber diet and/or supplementation with nutrients such as chromium, biotin, vitamin E, or herbs such as Gymnema sylvestre will often improve blood sugar control in diabetics. In such cases, the amount of insulin may need to be reduced in order to avoid a hypoglycemic reaction. Anyone taking insulin should consult the prescribing physician before making dietary changes or taking nutrients or herbs that are designed to lower blood sugar levels.

Summary of Interactions with Vitamins, Herbs, and Foods (for details about the summarized interactions, read the full article)

May be Beneficial: Depletion or interference—The medication may deplete or interfere with the absorption or function of the nutrient. Taking these nutrients may help replenish them.	DHEA
May be Beneficial: Supportive interaction—Taking these supplements may support or otherwise help your medication work better.	Biotin Chromium Fenugreek Gymnema sylvestre* Vitamin E
Avoid: Adverse interaction—Avoid these supplements when taking this medication because taking them together may cause undesirable or dangerous results.	Chromium* Gymnema sylvestre* Tobacco
Side effect reduction/prevention	None known
Reduced drug absorption/bioavailability	None known

An asterisk (*) next to an item in the summary indicates that the interaction is supported only by weak, fragmentary, and/or contradictory scientific evidence.

Interactions with Dietary Supplements

Dehydroepiandrosterone (DHEA)

Insulin has been shown to decrease the levels of DHEA and DHEA-sulfate in the blood.1 More research is needed to determine the significance of this finding.

Interactions with Herbs

Fenugreek (Trigonella foenum-graecum)

In a controlled study of patients with type 1 diabetes, fenugreek (100 grams per day for ten days) was reported to reduce blood sugar, urinary sugar excretion, serum cholesterol, and triglycerides, with no change in insulin levels.2 In a controlled study of people with type 2 diabetes, fenugreek (25 grams per day for 24 weeks) was reported to significantly reduce blood glucose levels.3 People using insulin should talk with their prescribing doctor before incorporating large amounts of fenugreek into their diet.

Gymnema sylvestre

Although no interactions have been reported, gymnema may decrease the required daily dose of insulin.4 Therefore, people currently using insulin for the treatment of diabetes should discuss the use of this herb with their healthcare professional.

Interactions with Foods and Other Compound

Food

Diet is an important factor in effective diabetes prevention and treatment. People using insulin should monitor their blood sugar carefully and talk with their doctor about the role of diet in diabetes control.

Alcohol

Alcohol may increase the action of insulin, leading to hypoglycemia (low blood sugar).5 People using insulin should avoid alcohol.

Tobacco (Nicotiana species)

Smoking may decrease insulin activity,6 and it compounds the health problems associated with diabetes. People using insulin are cautioned to avoid smoking.
