This is another coffee/chocolate extract that is very similar to caffeine in structure and function. It seems to have a slower and lesser effect compared to caffeine, meaning it lasts longer but doesn’t give you as much stimulation. Theobromine is a decent ingredient for increasing focus, intensity while reducing appetite but its fat burning effect doesn’t seem very significant. It is certainly a good support ingredient though and can help increase the effect of caffeine. Theobromine is very dangerous for dogs, so be careful when products contain this to keep it away from your dogs (example dropping pills) since they can’t metabolize this compound and it is basically poison to them. Theobromine again can give an euphoric effect, especially in women where it seems to help them reduce appetite quite well.
