“Magnesium acts as both an NMDA-receptor antagonist and a GABA-receptor agonist — the dual mechanism researchers point to for its role in deepening slow-wave sleep.”

— findings summarized in Nat Sci Sleep, 2025

“Running caused a significant increase in gastrointestinal permeability in the placebo trial, but this was almost completely blunted in the colostrum trial.”

— Marchbank et al., replicated in Davison et al., summarized in Nutrients, 2021
The all-year recovery case

Your system doesn't fail all at once. It fails one skipped night, one hard week, at a time.

Your gut takes damage every time you push hard. Your nervous system takes damage every time you under-sleep. Neither heals on a “when I remember” schedule — they heal on a nightly and daily one.

Join 300+ PeopleWho Decided Recovery Was Worth It

More men in their 20s, 30s, and 40s are getting the fundamentals right — and feeling it. The athlete who trains the next morning energized. The lifter who dropped the gimmicks and got composed. The student who sleeps like it matters and shows up sharp.

You're not alone in this. You're joining a community of 300+ people who decided their recovery, energy, and focus were worth one simple daily habit — not another shortcut.

The next result can be yours.

Component breakdown

DEEP

Magnesium Glycinate · night
Mechanism
NMDA-receptor block + GABA-A potentiation — suppressing excitatory signaling while enhancing the brain's inhibitory “calm” system.
Proof
Slow-wave sleep increased from 10.1 to 16.5 minutes (p<0.05) in a controlled trial. Held et al., cited in Nat Sci Sleep, 2025
“Quiets the racing mind. Deepens the sleep that actually repairs you.”

GUARD

Colostrum · day
Mechanism
Reduces zonulin and reseals gut tight junctions — normalizing the permeability that hard training loosens.
Proof
9-study systematic review — exercise-induced gut permeability reversed in the majority of controlled trials. Dziewiecka et al., Nutrients, 2022
“Seals the barrier training stresses — recovery isn't lost at the gut.”
Honesty note: the IGF-1 in colostrum works locally at the gut lining — a repair mechanism, not a systemic performance hack. Controlled, protein-matched trials show no meaningful rise in systemic IGF-1 from oral colostrum.

Reviews

We're new. So we'll show you the paperwork instead.

We could have filled this space with testimonials. We'd rather tell you the truth: the Recovery Stack just launched, and we don't have hundreds of reviews yet.

What we do have is the thing that actually matters before anyone has an opinion — the form on the label, the dose printed on the front, and a third-party test on every batch, for both DEEP and GUARD. Read the Certificate of Analysis and judge the products on what's in them.

When the reviews come, they'll be real ones. Verified buyers only.
