Decrease brain shrinkage and memory loss! Ayurveda consultant Dr. John Douillard says over 50, we produce less hydrochloric acid, a strong stomach secretion that allows absorption of vitamin B12. To boost memory by increasing HCL acid, take one Trikatu capsule 15-min before meals with 12 oz water for 3 months along with 3,000-4,000 micrograms B12 sublingual, and a supplement with B6 and folate for 3-4 weeks. Caution with folate if you consume more than 2 alcoholic drinks a day.
