L-serine, lion’s mane, L-methyl folate. I just ordered Inner Bounty Focus 14-in-1 Nootropic Brain Supplement with Lions Mane, Alpha GPC Choline, Vitamin C & B12, Taurine, Bacopa - Energy, Cognitive, Memory Support. It also contains coffee berry extract, which is supposed to be really great for memory problems. I also take turmeric curcurmin and a multi vitamin. I’m going to take Omega3, as well. I’ve started taking some other supplements, too. I’m diabetic, and have been taking berberine. It has kept my blood sugar in normal range.
