I started taking turmeric tablets last month for general aches and pains and the other alleged health benefits. I had no idea it was meant to have any effect on BG. About 1.5-2 weeks in, I noticed quite a massive reduction in my BG levels and had to reduce my insulin quite significantly. I wondered if it was the turmeric and when I looked it up, there was mention of it potentially reducing BG. However, 3.5 weeks in and I developed diarrhoea. I attributed it to the tablets so stopped taking them. It appears diarrhoea is a possible side effect although quite rare.
Maybe turmeric just has a big effect on me. :***:
