This alternative is the same high-potency 900mg standardized guarana extract, but in a smaller 60-count bottle. While its price per serving (15) is slightly higher than the 200-count, it still offers tremendous value for its strong efficacy and quality for users who don't need the largest bulk option immediately.

While seemingly lower in pure extract quantity, this alternative from Solaray combines both raw guarana and guarana seed extract. This blend could offer a fuller spectrum of the plant's compounds beyond just caffeine, which some users might perceive as a more 'complete' or nuanced effect compared to a highly concentrated, single-compound extract.
