MemoPryl and Sleep: What the Ingredients Say
MemoPryl and sleep are not linked by any claim on the bottle, and no sleep study of the capsule exists. The one sleep note in our sources is that St. John's wort can cause trouble sleeping. Poor sleep and forgetfulness are a reason to see a doctor.

MemoPryl and sleep have no proven link, and the bottle makes no sleep claim. Its front reads "Supports Focus*", not rest.
Nothing we read shows the six listed names improve sleep.
The six names02
What do the six listed names say about sleep?
Only St. John's wort has a sleep note, and it is a side effect. Trouble sleeping and restlessness are reported (NCCIH, St. John's wort).
For the other names, no sleep finding turned up. Filter the list below by group.

Names only: no amounts are published. Supplement labels must list each ingredient with its amount (21 CFR 101.36, supplement labels), so the bottle itself is the check.
Timing03
Could a daytime capsule disturb your nights?
It could, if a listed ingredient affects sleep, and St. John's wort is the one to watch. Directions are not published, so follow the bottle you receive.

When to ask04
When does poor sleep call for a doctor?
Poor sleep with new confusion or memory trouble is a reason to see a doctor. Dementia is not a normal part of aging, and warning signs deserve a check (CDC, dementia signs).
Keep taking prescribed medicine and ask your doctor or pharmacist before adding a capsule. More in memory basics.

FAQ06
Questions about sleep and herbal capsules
Can St. John's wort keep you awake?
It can in some people. Trouble sleeping and restlessness are among its reported side effects (NCCIH, St. John's wort). Note the date you began and ask a pharmacist if your nights change.
Do bedtime supplements help memory?
No source we read shows that. Brain-health reviewers found insufficient evidence for any supplement in most adults (AARP/GCBH, brain supplements), so sleep habits and a doctor visit come first.
Why do I forget more when I sleep badly?
Tiredness often makes recall worse, and it is a common reason for lapses. If forgetting is new or growing, a doctor can look for causes (Alzheimer's Assoc., 10 signs).
