Third-party records
What we found outside Oak's own site. BBB, its named pharmacy partner (or lack of one), and whether it publishes a real HIPAA notice.

No BBB profile found for Oak / Oak Longevity Holdings Corp.
Pharmacy partner
Oak does not name the specific pharmacy that fills or compounds its medications (checked privacy policy, 2026-08-30). That is the norm for this category, not unusual for Oak specifically. Most providers we've checked don't name one either. Discloses pharmacy services generically ("health care providers...including pharmacy services"). No pharmacy named.
HIPAA disclosure
Not found. Checked 2026-08-30. Privacy policy explicitly states it does NOT cover PHI and that a separate "Oak Notice of Privacy Practices" exists for that. But that document isn't linked from this page, so we couldn't verify it actually contains real HIPAA disclosures. Referencing a notice you don't link to isn't the same as publishing one.
Who operates it
Operated by Leaf Longevity Holdings Corp. Published on Oak's own site, checked 2026-09-14. Published as “Leaf Longevity Holdings Corp. DBA Oak Longevity”. No address anywhere on the site.
Cancelling and refunds
No written cancellation or refund terms found on the site (checked 2026-09-14). A “cancel anytime” claim appears, but no written terms. No notice period, no fee schedule, nothing on partially used periods. The policy sits behind a footer link; its text doesn't appear on the pages where the price is quoted.
