Quick answer: Liquid supplements are measured in drops or a dropper and are usually diluted in water. The seller does not list Cognivex’s other ingredients on its page, so check the label for anything you avoid.
Why drops?
Drops are easy to adjust and suit people who prefer not to swallow pills. They also make it easier to take too much, so measure carefully and follow the label.
Dilution
Many drops are mixed into a glass of water. Follow the directions printed on your own bottle, because serving sizes differ between products and sellers.
Storage
Keep the bottle tightly closed, away from heat and sunlight and out of reach of children. Methylene blue stains, so use care with clothing and surfaces.
