  • Choose Reputable Brands: Select supplements from reputable brands that have a long history of quality and safety. Read online reviews and check for any complaints or recalls.
  • Avoid Proprietary Blends: Avoid supplements that contain proprietary blends of ingredients, as the exact amounts of each ingredient are not disclosed. This makes it difficult to assess the efficacy and safety of the product.
  • Store Supplements Properly: Store supplements in a cool, dry place away from direct sunlight and moisture. Follow the storage instructions on the product label.
  • Do Not Exceed Recommended Dose: Do not exceed the recommended dose of a supplement. Taking more than the recommended dose will not necessarily improve its effectiveness and may increase the risk of side effects.
  • Rotate Supplements: Consider rotating supplements every few months to prevent tolerance and reduce the risk of side effects.
  • Be Patient: It may take several weeks or months to see the full effects of a supplement. Be patient and consistent with your use.
  • Combine with Lifestyle Changes: Combine supplement use with healthy lifestyle changes, such as a balanced diet, regular exercise, adequate sleep, and stress management. These lifestyle changes can enhance the benefits of supplements and improve overall cognitive function.
  • Re-evaluate Periodically: Periodically re-evaluate your need for supplements. If you are no longer experiencing any benefits or are experiencing side effects
