The focus-supplement category is crowded. Most products don't survive scrutiny. Here are the five criteria that matter.
1. Caffeine + L-theanine pairing
This is the most-studied calm-focus combination in cognitive science. If a focus supplement skips the pairing or uses asymmetric ratios (lots of caffeine, trace L-theanine), it's missing the point.
2. Format and onset
Capsules: 30–60 minute onset, significant loss to liver metabolism. Drinks: ~20 minute onset, often sugar-laden. Drops (sublingual): 1–5 minute onset, dose-controllable.
3. Ingredient transparency
Proprietary blends that hide actual doses are a red flag. Real formulations publish exact mg amounts.
4. No artificial fillers
Sugar, synthetic stimulants, artificial flavours, dyes — none of these support the cognitive outcome. They support the price margin.
5. Third-party testing
The supplement industry is lightly regulated. Third-party verification of dosing and purity is the additional layer that separates serious products from supermarket brands.
