According to common HumanN superbeets reviews, the memory and focus gummies work by increasing blood flow to the brain. The combination of nitric oxide and resveratrol (antioxidants) helps to increase blood flow through blood vessel dilation. It also reduces inflammation and prevents any damage from oxidative stress.
In addition, the coffee fruit extract in the gummies boosts neuroprotective protein function, also called brain-derived neurotrophic factor. The BDNF regulates brain cell survival and growth to aid cognitive functions, including learning and memory.
