Neuroprotective cognitive support

Formula re: Contains

PQQ is a newly discovered micronutrient that is naturally found in foods such as soybeans, parsley, and green pepper. Recent preclinical research suggests that as an antioxidant it may profoundly impact nerves and neurological health. Human studies indicate it may help improve cognitive function. PQQ supplementation also promotes mitochondrial biogenesis, which may contribute to slowing the aging process and increasing energy levels.
