How to Choose (The “Marketer’s Audit”)
When you are shopping for these, look for these three “Trust Signals” on the label:
Patented Ingredients: Names like Cognizin®, KSM-66®, or Suntheanine® mean the ingredient itself has undergone specific clinical research.
No “Proprietary Blends”: Avoid brands that hide dosages behind a “blend” name. You should know exactly how many milligrams of each ingredient you are taking.
Third-Party Seals: Look for NSF Certified for Sport, Informed Choice, or USP seals.
