Red light therapy lowers blood sugar and mitigates glucose spikes

The researchers found that 670 nanometers (nm) of red light stimulated energy production within mitochondria, the tiny powerhouses within cells, leading to increased consumption of glucose. In particular, it led to a 27.7% reduction in blood glucose levels following glucose intake, and it reduced maximum glucose spiking by 7.5%.
