Consumer advice
If you want cognitive support, buy caffeine (200mg) and a standalone B-complex vitamin separately for ~$15 total—you'll know exactly what you're taking and save money. If you're interested in adaptogens like rhodiola or ginseng, purchase those individually at verified doses (120-400mg for rhodiola, 200-400mg for ginseng) from brands that list exact amounts. Avoid proprietary blends; they exist to hide underdosing. Check the label for actual mg amounts before buying any 'focus' supplement."
