Alertness / energy (caffeine effects)

Strong Evidence

Caffeine reliably improves alertness, vigilance, and short-term energy. Cola nut is one natural source.

How it works

Cola nut contains caffeine (about 1.5-3% by weight) and theobromine, providing CNS stimulation similar to that of coffee or tea. Tannins and polyphenols add astringency. In supplements, cola nut is included as a natural caffeine source in energy and weight-loss blends.

Dosage

There is no RDA. Cola nut extracts are typically dosed to provide 50-200 mg of caffeine per serving. DSLD does not provide a median dose for this entry.

When and how to take it

Take earlier in the day to avoid sleep disruption. Avoid within 6-8 hours of bedtime.
