Frequently Asked Questions
What is an HSA or FSA?
Health Savings Accounts (HSAs) let you set aside pre-tax dollars to pay for qualified health expenses. HSAs are linked to high-deductible health plans, and funds in these accounts roll over year after year.
Flexible Spending Accounts (FSAs) allow you to use pre-tax dollars for eligible health expenses. Unlike HSAs, FSAs are not tied to a specific health plan and often require you to use the funds within the calendar year. FSAs are typically provided by employers.
Can I use HSA/FSA for subscriptions?
Yes. Subscriptions require a short health assessment and a Letter of Medical Necessity.
What is a Letter of Medical Necessity (LMN)?
A Letter of Medical Necessity is a document from a licensed healthcare provider that verifies the medical necessity of a product or service, making it eligible to purchase using your HSA or FSA. This might include items or treatments like supplements or physical therapy that aren’t automatically recognized as eligible expenses.
Do I need a new Letter of Medical Necessity for every purchase?
No. Your LMN is valid for 12 months. You can use the same letter for any qualifying PureHealth Research purchases made within one year of the letter's date.
What if my claim is denied?
Most HSA/FSA providers accept LMNs from Flex. If they request more information, please contact the Flex support team at support@withflex.com
I don’t have an HSA/FSA. Can I still benefit from Flex?
Unfortunately, Flex services are for individuals who have HSA or FSA accounts. We encourage you to ask your employer about information on your HSA or FSA!
Do I need to do anything with my Letter of Medical Necessity?
You should keep it on file for at least three years in the event of an IRS audit of your HSA or FSA account. Occasionally, FSAs may ask for the Letter to confirm the eligibility of your purchase.

Cortisol doesn't just affect how you feel under pressure – it could shape your mood, your appetite and your sleep long after the stressful moment has passed. Cortisol & Sleep Formula gives the body the support it may be missing.

They may share one root cause.
The Formula
Cortisol & Sleep Formula is a doctor-approved blend of cortisol capsules by PureHealth Research – made with ashwagandha, saffron, magnesium and L-theanine to help maintain steady cortisol response, encourage a balanced mood, and promote the kind of calm that makes it easier to fall asleep and wake up refreshed.
The Cycle
Stress doesn't stay in your head. It could follow you into the evening, keep your thoughts racing after the lights go off and leave you reaching for something sweet or salty just to feel steadier. Then comes the part nobody warns you about: poor sleep makes the next day's stress harder to handle and the cycle starts again.
The Question
Most people accept this as just "being busy" or "getting older." But what if your body's stress-response system simply needed better support?

Who Might Benefit Most?
The Science Behind the Formula
Did You Know Cortisol Naturally Peaks in the Morning and Should Fall by Bedtime?
For most people, cortisol follows a circadian rhythm — high in the morning to help you wake up, then gradually easing through the day so your body can wind down at night. When stress keeps that rhythm elevated, falling asleep can feel harder, mood can feel less steady, and cravings can creep in at the worst times.
Cortisol & Sleep Formula combines six research-backed ingredients, each studied for a different piece of this cycle:
An adaptogenic herb shown in a randomized, placebo-controlled trial to significantly lower serum cortisol and ease stress scores in adults with chronic stress.
A highly absorbable form of magnesium studied for calming the nervous system and easing everyday stress.
A naturally calming flower extract studied for modulating the cortisol response to stress, lifting low mood, and helping address stress-driven cravings.
Works alongside magnesium to support a healthy stress response and mood balance, including during PMS.
A calming amino acid studied for promoting relaxed, alpha-wave focus and a steady mind, without drowsiness.
A natural bioavailability enhancer, included to help your body better absorb this formula's nutrients.
