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.

Protein builds muscle. Creatine powers it. Electrolytes keep it functioning. I haven’t seen another formula do all three this cleanly.

Why Protein Alone May Not Be Enough Anymore?
Yeast Protein + Creatine + Hydration is a 7-in-1 daily formula for adults who want to preserve lean muscle, stay hydrated, and support healthy metabolism during weight loss.
Each scoop delivers: 10 g fermented yeast protein (Yestein®), a full 5 g dose of creatine monohydrate, three electrolytes (magnesium glycinate, sodium citrate, potassium citrate), plus biotin and iron.
What happens during a calorie deficit
The scale is moving. But something else may be moving too.
When the body is in a significant calorie deficit, it doesn’t only draw from fat stores — it can break down lean muscle tissue for energy.1 Research points to three reasons why a standard diet can quietly cost you muscle:
Muscle Loss Risk
Muscle protein breakdown speeds up — and if protein intake drops along with appetite, the body may not have enough raw material to rebuild lean tissue.
Reduced Muscle Energy
Energy production (ATP) can be affected, which may influence strength, recovery, and how long muscles hold up during activity
Electrolyte Depletion
Electrolyte levels can drop, affecting how well muscles contract and how much fatigue sets in.
A standard protein shake addresses the first issue. This formula was built to address all three.

Who Might Benefit Most?
Why Creatine + Protein?
Why Not Just Protein?
What’s Inside Yeast Protein + Creatine + Hydration?
Delivers all nine essential amino acids your muscles need to repair themselves, with a PDCAAS score of 1.0 — the same top score as whey. Unlike whey, it’s completely dairy-free and gentle on digestion. A clinical trial found adults taking yeast protein alongside resistance training gained as much lean mass as those taking whey.
Every time you move, your muscles burn through ATP fast — creatine helps your body replenish it.9 Research shows creatine supplementation may significantly increase lean mass versus placebo, including in older adults on a daily maintenance dose.
Involved in hundreds of processes in the body, including muscle contraction and relaxation.18 Low magnesium can mean stiff, crampy, slow-to-recover muscles; research suggests supplementation may ease soreness and support recovery
Helps your body retain the water muscles need to function, and carries the electrical signals that trigger contraction. It’s also the electrolyte you lose most through sweat.
Works alongside sodium to balance fluid inside and outside muscle cells and support nerve signaling — which may help address cramps linked to low electrolyte levels.
Helps convert carbs, fats, and protein into usable energy — the spark behind your metabolism.
Helps red blood cells carry oxygen to your muscles; low iron can mean fatigue, low stamina, and slower recovery.

Why It Matters:
Most protein supplements deliver amino acids and stop there. Few include a full clinical dose of creatine, and fewer still add electrolytes — even though muscle preservation depends on all three.
The Bottom Line
Yeast Protein + Creatine + Hydration combines complete plant protein, a full clinical dose of creatine, and three key electrolytes — in one scoop, at fully-disclosed doses. It may help you:
- PRESERVE lean muscle during a weight loss journey or calorie restriction
- REPLENISH cellular energy (ATP) to help muscles stay strong and recover faster
- STAY hydrated and support healthy muscle function
- EASE post-exercise soreness and support recovery
- GET complete, dairy-free protein that’s easy on digestion
Quality You Can Trust
Every container is manufactured in an SQF-certified facility and third-party tested for safety and purity. No proprietary blends — seven fully-disclosed, natural ingredients.

Biotin: helps your body convert carbohydrates, fats, and proteins into usable energy.
Iron: supports oxygen delivery to working muscles, contributing to stamina and daily energy levels.
We're committed to improving our formulas based on the latest research, which can affect serving size and cause slight variations in ingredients.
