why we’re different

Not all supplements are created equal.

At Parsley, ‘professional grade’ means every supplement is third-party tested for quality and purity, and manufactured in NSF/USP-certified, cGMP-compliant U.S. facilities that meet FDA standards.


Our clinicians know which supplements actually move the needle — and which don't. Every formula is selected for clinical evidence, optimal bioavailability, and meaningful dosing. Not what's cheapest to manufacture. What actually works.

Many of us don’t get the nutrient density we need from our food, even if we eat healthy diets. That includes me, which is why there are certain supplements I take every day.

Why Choose Parsley Supplements
PHYSICIAN-FORMULATED
Built by Clinicians, Not Marketers
Every formula is designed by physicians who have treated over 50,000 patients using a root-cause approach — not by a marketing team chasing supplement trends.
CLINICALLY DOSED
Meaningful Amounts, Not Token Doses
We use the doses supported by clinical research — not the minimum amounts needed to list an ingredient on the label. Every dose is designed to actually move the needle.
THIRD-PARTY TESTED
Purity and Potency Verified
Every supplement is third-party tested and manufactured in NSF or USP-certified, cGMP-compliant U.S. facilities that meet FDA standards. No shortcuts.
Frequently Asked Questions

Three things separate our supplements from what you'll find at most retailers: physician-formulated with bioavailable ingredient forms (methylated B vitamins, bisglycinate magnesium, MK-7 K2), clinically meaningful doses based on actual research, and third-party testing for purity and potency. These are the same professional-grade supplements Parsley clinicians prescribe to their patients.

Longevity & Healthspan

If you're focused on aging well, maintaining energy, or protecting your long-term health, the most powerful thing you can do is understand where your body stands today. Parsley Health physicians use advanced testing and a root-cause approach to build a plan around you — not just a standard checkup.
