Claims to be careful with. Supplements can't "boost IQ," "unlock 100% of your brain" or prevent dementia. Products claiming to treat ADHD, depression or anxiety are making drug claims.
See a doctor if…
You have sudden confusion, trouble speaking, weakness on one side or a severe headache (call 911), or ongoing problems with mood, focus or sleep.
