Brain Factors by Thorne

If you’re curious about an NAD supplement for steady daytime energy and clearer thinking, nicotinamide riboside fits. It’s practical for adults who don’t want the flush from high-dose niacin, and for people tracking Homocysteine who also want gentle methylation support from betaine. Coffee fruit extract adds an alertness edge with negligible caffeine, useful when you want focus without another cup of coffee.

Nicotinamide riboside raises NAD+ (the cell’s energy currency for making ATP) in blood and tissues within 2 to 4 weeks, which many notice as better stamina across the day. The coffee fruit extract used here has been shown to trigger a measurable rise in BDNF, a brain growth signal tied to learning and memory, within hours. Betaine (trimethylglycine) donates methyl groups, which helps convert homocysteine back to methionine; that’s why some people see Homocysteine improve when betaine is paired with folate and B12.

Take one capsule daily, preferably in the morning so the coffee fruit extract’s alertness effect lines up with your day. Food is optional, though a small snack can help sensitive stomachs. If you track labs, re-check NAD+ metabolites if available at 4 to 8 weeks and Homocysteine after 8 to 12 weeks. Folate and Vitamin B12 status should be adequate to get the most from betaine on Homocysteine.

Avoid NAD boosters if you have an active cancer diagnosis unless your oncology team approves. If your LDL cholesterol tends to run high, note that betaine has raised LDL in certain high-dose clinical settings, so monitor your lipid panel. Pregnancy and breastfeeding: data are limited, so conservative practice is to avoid. Very sensitive sleepers should take it before noon to prevent late-day alertness.
