YES, turmeric in the diet is perfectly safe to consume along with diabetes medications. However, turmeric supplements should be taken with care and at a gap of about 3-4 hours with diabetes medicines.
Curcumin, an active ingredient of turmeric assists in treatment, management and prevention of diabetes.
Studies have shown that curcumin, when taken with diabetes drugs has no adverse interactions. On the contrary, it gives better results and can inhibit the side effects of these medicines.
Care should be taken when taking turmeric with the medicines, as high dosage could lower blood glucose and result in hypoglycemia.
Let us take a look at what scientists have to say about these effects.
Turmeric is good for Diabetes
The working mechanism of turmeric and anti-diabetic medicines is quite similar.
Curcumin improves insulin sensitivity and lipid parameters by inhibiting Tumor Necrosis Factor-alpha (TNF-α) and reducing plasma free fatty acids. The drug rosiglitazone works in the same manner 
Turmeric is also beneficial in the prevention and treatment of several other health complications which occur as a result of diabetes such as neuropathic pain, nephropathy, retinopathy, diabetic wounds, non-alcoholic fatty liver disease and cardiovascular ailments.     
Turmeric does not Interact with Diabetes Drugs
Studies have shown that turmeric or curcumin, when taken with some frequently prescribed anti-diabetic medicines do not interfere with the working of the drug.
In one such study, when curcumin capsules were given along with glyburide (a drug used for lowering lipid levels in diabetes) were given to diabetic patients, positive results were obtained with improved lipid and sugar profiles. No case of hypoglycemia (low blood glucose) was detected. 
The interaction of curcumin with the action of drugs may depend on the dosage. As seen in another study, curcumin at low doses did not affect the activity of the drug gliclazide (used for the treatment of type 2 diabetes). However, in high doses, it leads to a higher reduction in glucose levels. 
Therefore, it is advised to limit the intake of supplemental doses of turmeric and curcumin with diabetes medications to reduce the risk of hypoglycemia.
Therefore, it is recommended to maintain a gap of 3-4 hours between taking golden paste and diabetes drugs.
Turmeric along with Drugs Gives Better Results in Diabetes
Scientists consider turmeric as an effective adjuvant in anti-diabetic therapy. When metformin, a widely used anti-diabetic drug was given along with turmeric to diabetic patients, it resulted in decreased glucose and lipid levels and an enhanced antioxidant status. 
Similarly, curcumin capsules given with another diabetes drug glyburide resulted in better glycemic control. 
Curcumin along with gliclazide medicine can also have a more profound analgesic effect and protect against the development of diabetic neuropathy. 
Piperine, a bioenhancer which increases the absorption of turmeric can improve the therapeutic effect of the drug metformin. 
Thus, intake of turmeric or golden paste can help one lower the doses of anti-diabetic drugs and their side effects.
Turmeric may alleviate the side effects of metformin
Metformin, widely used the drug for treatment of diabetes can have adverse effects such as oxidative stress, mitochondrial damage and cell injury. It also increases one’s risk of developing Alzheimer’s disease.
Anti-oxidants like curcumin can reverse these side effects of metformin and protect the body from damage and disorders.
