Every batch dose-verified, lab-tested, and documented before it ships. Four ingredients with published evidence behind them — nothing else. Request an invite for early access and founding pricing.
Most altitude supplements round potency to a marketing number and skip independent testing entirely. We publish the actual result, every batch.
No proprietary blends, no trendy adaptogens added for the label. If a randomized trial hasn't tested it, it doesn't go in the tablet — including ingredients we used to sell. Select any ingredient below.
Naturally found in strawberries and citrus. Dosed at roughly half the amount used in the original study — oral absorption saturates well before the full studied dose, so this isn't a corner cut, it's close to the point of diminishing returns.
Naturally found in almonds and sunflower seeds. Studied alongside vitamin C and alpha-lipoic acid in climbers ascending past 5,000m — part of the combination, not a standalone claim.
Naturally found in spinach and broccoli. The third ingredient in the actual studied stack — most brands quietly drop it and call the remaining two the same combination. We didn't. A larger follow-up trial (n=83) didn't replicate the original benefit — we say so in "Honest Take," not just here.
A standardized extract, not raw powder — raw ginger's gingerol content varies too much batch to batch to verify honestly. Well-evidenced as a general antiemetic (surgery, chemotherapy, pregnancy). Not specifically trialed for altitude sickness — but nausea is one of the four core symptoms doctors use to diagnose it, and nausea is nausea.
Our original hero ingredient, from a mountain root. A rigorous randomized controlled trial (n=102) later showed no significant benefit over placebo. We removed it rather than keep the story.
The classic fan-shaped leaf. No significant effect on AMS prevention across multiple clinical reviews. Common in this category anyway. Not in ours.
Not a real, sourceable ingredient. No legitimate supplement raises red blood cell production. Claims like this are why the category has a trust problem.
Supplement evidence for altitude sickness is thin across the entire category — including our own product. Here's what the research actually supports, plainly.
Four checkpoints, in order — same as a real climb.
Raw extract sourced with species documentation required at intake — not assumed from the supplier's label.
Third-party HPLC species confirmation, potency, heavy metals, and microbial testing — every batch, not spot-checked.
The Certificate of Analysis ships with a scannable code on the pack. You see what we saw.
Blister-packed for pack weight, sized to one climb's worth — not a bulk bottle you don't need.
I started this after one too many runs and hikes where I underperformed despite training properly for them — and every "altitude" product on the shelf made the same vague promises with nothing real behind them. So we built the opposite: publish what we can actually prove, and cut what we can't. That included removing the ingredient we launched with, once a real trial showed it didn't hold up. If the evidence ever stops supporting something in this tablet, it comes out — no matter how good it looks on the label.
