Your body runs on minerals. Most of us run low.
JevityRx makes a short list of foundational supplements using the forms your body actually absorbs, dosed to match the research, with every batch third-party tested.
Start with the two that matter most.
We would rather get a short list right than sell you an aisle. Both formulas use the absorbable form at the dose the research actually used.

Magnesium Glycinate
The mineral your heart rhythm, sleep, and stress response run on, in the chelated form built for absorption. 400mg with B6 + Zinc, taken nightly before bed.†

Vitamin D3 + K2
D3 for immune defense, mood, and bone support. K2 (MK-7) to help direct calcium where it belongs. Two nutrients that were always meant to work together.†
How we make them.
Four commitments that apply to every pouch we ship.
Forms that absorb
We use magnesium glycinate and K2 as MK-7. The premium forms cost more to make and absorb better, which is why we use them.
Full research doses
400mg of magnesium per serving, the same range used in the clinical research. If a dose would be too small to matter, we leave the ingredient out.
Tested every batch
Every numbered batch is third-party tested for identity, potency, and heavy metals before it ships.
Guaranteed
Use it for 30 days. If you do not feel a difference, we refund you and you keep the pouch.
Why supplement at all? Because the food gap is real.
An estimated 48% of Americans get less magnesium than their body needs from food alone.† Depleted soil, processed diets, stress, and caffeine all pull in the wrong direction. You will not feel a deficiency forming. You will just feel what it does to your sleep, your stress, and your recovery.
JevityRx focuses on the handful of foundational nutrients where that gap shows up most, restored at a full dose.
† Based on NHANES dietary intake data vs. Estimated Average Requirement. See studies in footer.

A few of the most recent verified reviews.
Sleeping through the night again
I was a 3AM waker for years and blamed stress. Two weeks on the glycinate and I stopped surfacing at night. I did not expect a powder to be the thing that fixed it.
My husband and I both take it
He takes it for recovery, I take it for the wind-down. It is the first supplement we have actually finished a pouch of and reordered without thinking about it.
Finally a real dose
I checked my multivitamin after reading their label breakdown. 50mg of oxide. This is 400mg of glycinate. Night and day, literally. Calmer evenings, better mornings.
GUARANTEE
Feel the difference in 30 days, or it is free.
Take it nightly for a month. If your sleep, stress, and recovery do not feel noticeably different, email us and we refund your order in full. No return label needed.
Common questions.
What makes glycinate better than the magnesium in my multivitamin?
Most multivitamins use magnesium oxide, a form with very low absorption, at a fraction of a meaningful dose. Glycinate binds magnesium to the amino acid glycine, which your body absorbs efficiently and which is gentle on the stomach. You get the full 400mg where it matters.
When will I feel something?
Most customers report calmer evenings and deeper sleep within the first two weeks of nightly use. Give it a full 30 days. That is why the guarantee is 30 days long.
Is it safe to take every night?
Magnesium glycinate is one of the most studied and well-tolerated supplement forms available. As with any supplement, check with your doctor first, especially if you take medications or have a kidney condition.
How does the subscription work?
Your first pouch ships at the discounted first-order price, then renews at the standard price every 30 days with free shipping. Pause, skip, or cancel in two clicks from your account page. No phone calls, no hoops.
