A phosphatidylserine supplier should be evaluated on manufacturing capability, quality control, product document readiness, source transparency, and responsiveness to application questions.
Useful proof points include factory imagery, R&D cooperation, production license information, equipment visibility, and clear product information that avoids unsupported claims.
Ask for specifications, COA, packaging options, lead time, MOQ, sample policy, and the intended application before comparing prices.
