Altitude sickness rarely announces itself politely. You feel fine at the trailhead, then a dull headache and a queasy stomach roll in somewhere above the treeline. The supplements below target what your body loses as you climb: sodium and other electrolytes (salts your body needs to work) sweated out, plus ginger for the nausea that turns a good hike sour. If you want the short answer: the Herbal Roots Organic Ginger Capsules are the crowd favorite for settling a churning stomach, while the SaltStick FastChews are the pick when altitude hits hardest on a trek and you need salt back in your system fast.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Below you’ll find how each option works in the real world, what to pack for a climb, and which one suits your trip. These are the supplements worth considering for altitude sickness, ranked by what actually helps on the mountain.
Top Picks
How To Choose The Best Supplements for Altitude Sickness
Altitude sickness is really two problems wearing one name. The first is fluid and electrolyte loss — you breathe harder and sweat more in dry mountain air, and sodium, potassium, calcium and magnesium leave your body with it. The second is nausea and stomach upset, which is where ginger earns its keep. A supplement that only does one of those jobs leaves you half-covered.
Match the form to how fast you need it
A chewable tablet dissolves in your mouth and gets to work in minutes — useful when a headache is already building at 3,000 metres and you have no water to mix a powder into. Capsules are slower but easier to carry in bulk and simpler to swallow on a rest break. If your climb is a multi-day trek, a mix of both covers you.
Check what the electrolyte blend actually contains
The four that matter are sodium, potassium, calcium and magnesium. Sodium is the big one on a climb, because it is what you lose most heavily through sweat. A chew or tablet that lists all four gives you broader coverage than one that leans on a single mineral, and a sugar-free formula keeps the dose light enough to repeat through the day.
Read the ingredient list for fillers
A ginger capsule that is mostly binder delivers little ginger. Look for a single-ingredient product or one that states USDA Organic and names gingerols — the plant compounds in ginger. Fewer additives means the dose is closer to what the label promises.

Detailed Reviews
1. Herbal Roots Organic Ginger Capsules
Our pick — 4.5+★ from 950+ verified ratings; the strongest balance of quality and price.
The single-ingredient ginger capsule that turns a queasy stomach around without leaving an aftertaste.
Altitude nausea is the symptom that ruins a trek fastest, and this is the pick built squarely for it. Every capsule is USDA Certified Organic ginger with no fillers, binders or additives — so the whole dose is the herb, not a bulking agent. That matters when you are taking it several times a day on a climb and want nothing extra riding along.
What wins people over is how broadly the relief lands. Buyers report it settles nausea first and everyday digestion second, including heartburn and general upset stomach. It has already been 3rd party tested for purity, identity, heavy metals and microbes — the kind of testing that tells you what is actually in the bottle. The capsules come in a compact bottle that slips into a pack pocket without adding clutter.
Here is the honest catch: a few buyers find the price on the high side for the supply, and that is the trade-off you make for certified-organic, filler-free ginger. It is also a capsule, not a chew, so it takes a swallow of water on the trail. And unlike the SaltStick chews, it does not replace the sodium and potassium you are sweating out on a hard climb — pair the two if your trip is strenuous.
What earns it the top spot
- USDA Certified Organic ginger in a vegan capsule — single ingredient, no fillers or binders
- 3rd party tested per batch for purity, identity, heavy metals and microbes
- Addresses nausea and everyday digestive upset in one capsule
- No weird aftertaste, which makes repeat dosing on a climb easy
Where it asks you to compromise
- Some buyers find the supply price on the higher side
- A capsule needs water to swallow, unlike a chewable
- No electrolytes in the formula — it is a ginger product, not a hydration one
Reach for this if: nausea and stomach upset are your main altitude symptoms and you want a clean, certified-organic ginger capsule with nothing extra in it.
Pair it instead if: you are also sweating heavily on the climb — add an electrolyte chew alongside, because this one does not replace lost sodium.
2. Venture Pal Chewable Electrolyte Tablets
Eighty fast-melt tablets that replace the salt you sweat out without carrying a drop of extra water.
Eighty tablets is the headline here, and it is the reason this is the buy for a multi-day trek. The variety pack means you are not stuck with one flavor for a whole week on the mountain. Each tablet packs sodium, magnesium, potassium and calcium — the four electrolytes you lose through sweat — into a bite-sized chew that dissolves almost immediately. No mixing, no bottle, no waiting.
For altitude specifically, the convenience is the point. When your hands are cold and you are breathing hard at height, chewing a tablet beats digging out a powder sachet and finding clean water. Half-marathon and hike buyers describe slipping them into a hydration bladder setup so only plain water goes in the pack. It is zero sugar and gluten free, which keeps the dose light enough to repeat through a long day. The bottle measures 6.65 by 4.29 by 1.69 inches and weighs 7.41 ounces — a little bulkier than a small capsule bottle, but still a pocket-sized carry.
The catch is worth naming plainly. These contain sugar alcohols, and a handful of buyers find the sweetener noticeable. Take too many in a short window and a couple of people report stomach urgency — one runner taking one per mile hit that around mile 6. Space your doses and this stays a non-issue.
Why the pack size wins: 80 fast-dissolve tablets across a variety of flavors give you a full trek’s worth of salt replacement in one bottle, with zero sugar and no water needed.
Dose them sensibly: sugar alcohols are in the formula, so a sensible pace between tablets keeps the stomach settled on long efforts.
Load this in your daypack if: you want an easy, no-water electrolyte top-up for a long climb and prefer chewing to mixing.
Look elsewhere if: you need a pure ginger product for nausea — this one handles salt and fluids, not stomach settling.
3. Himalaya Organic Ginger Root Capsules
A pure ginger extract in a glass bottle, built for the stomach that turns on you at height.
Himalaya takes a different route than the Herbal Roots pick above: instead of crushed ginger root powder, this uses an organic ginger extract inspired by Ayurveda. It lands at a lighter 3.04 ounces and measures 3.56 by 2 by 2 inches, so it takes up less pack room than the heavier ginger bottle on this list. It is a 60-day supply in a glass bottle — no plastic smell, no chemical aftertaste, which buyers single out as a reason they keep coming back.
What carries this one is how quickly it settles the stomach. The effectiveness lands hardest in the feedback, with digestion running second — it is aimed at occasional nausea and general stomach upset. Muscle and joint support rounds out the label, and the formula is vegan and non-GMO with no gluten, fillers, dairy, soy or corn. If you are the type who already carries a ginger tea or chews on the trail, a caplet is simply less fuss in cold weather.
One fair warning: a few buyers find the caplets harder to swallow than expected, and one order arrived with roughly 20% of the tablets broken in half — worth checking your bottle on arrival. Neither changes what the product does, but both are honest parts of owning a fragile glass-packed supplement. It is also slower than a chew, so it is a tool to take before the nausea peaks rather than after.
Where it shines: organic ginger extract in a 60-day glass-bottled supply, aimed at occasional nausea and stomach upset with a clean ingredient list.
Handle with a little care: a few caplets arrive broken and swallowing is mixed — inspect the bottle on arrival and take with water.
Your pick if: you want a potent, single-herb ginger caplet in a glass bottle and plan to dose before nausea sets in.
Think again if: you need something you can chew one-handed at altitude — a chew will serve you faster.
4. SaltStick Electrolyte FastChews
Sixty peach chews that go to work in minutes, sized for the moment altitude hits on a hard climb.
SaltStick is the pick when you are mid-trek and altitude is winning. Chew two tablets every 30 minutes during exertion and drink water as needed — that is the whole protocol, and it is why this works on a steep ascent where digging out a powder is not an option. The formula carries sodium, potassium, calcium and magnesium, everything you sweat out on the way up, and the maker claims it absorbs faster than the leading sports drink or electrolyte powders. Just chew and feel it land.
What wins people over is the flavor — the peach gets named again and again. It is sweet-tart and easy to chew and swallow, which matters when you are eating one every half hour on a climb. Buyers on a four-person Salkantay trek in Peru credit it with getting the group through altitude sickness and dehydration. It is non-GMO, vegan, gluten free with no artificial colors or sweeteners, and the 4.4-ounce bottle is small enough to ride in a jacket pocket.
The honest limit: this is a fast electrolyte tool, not a nausea remedy. If your altitude problem is a churning stomach, the ginger picks above do that job — SaltStick replaces what you lose. And a handful of buyers find the peach flavor merely okay, so if you are flavor-sensitive, taste-test before you commit a whole trek to one bottle.
What makes it stand out
- Chew-and-go protocol — no water or mixing needed, so it works on a steep climb
- Sodium, potassium, calcium and magnesium in one sweet-tart chew
- Non-GMO, vegan and gluten free with no artificial colors or sweeteners
- Carried on a high-altitude trek where a group relied on it for dehydration
Where it stops short
- It rebuilds electrolytes but does nothing for nausea or stomach upset
- A small number of buyers find the peach flavor only okay
Best for the trailhead: hikers and trekkers who want salt back in fast, in a form they can chew without stopping to mix anything.
Not your pick if: the nausea is the problem — reach for a ginger capsule instead and keep these for the salt loss.
5. DHM 1,000mg with Electrolytes
A recovery tablet for the morning after, when a rough night leaves you foggy and parched.
This one sits in a different lane from the others, and it is worth saying plainly: DHM is a liver-support supplement with electrolytes, made for recovery after a hard evening rather than for the climb itself. If your trip includes a celebration at base camp, this is the morning-after reset — 1,000mg of DHM per tablet in a 30-tablet bottle, third-party tested for microbes and heavy metals in the USA from globally sourced ingredients. Non-GMO and gluten free.
Where it earns its place is the recovery it delivers. Buyers who take it after a night of drinking report waking clearer than expected, with less fog and grogginess and better sleep. The electrolytes do the same rehydration job the chews above handle, just in tablet form, which is why it overlaps with the rest of the list on hydration while adding liver support on top. The bottle is compact at 2.08 ounces.
The catch is the pill itself. The tablets run large and chalky, and a number of buyers find them hard to swallow — some cut them in half. It is also built for post-exertion recovery, not for altitude nausea or a mid-climb salt top-up, so it is a companion to the picks above rather than a replacement.
The recovery angle: 1,000mg of DHM per tablet plus electrolytes, third-party tested and built for the foggy morning after a heavy night.
Size up the pill: the tablets are large and chalky and some buyers halve them — take with plenty of water.
Add this if: your trip has a celebration in it and you want a tested DHM plus electrolyte tablet to bounce back the next morning.
Leave it out if: your only need is altitude nausea or mid-climb salt — the ginger and chew picks cover those better.
Know the Specs
Electrolytes and why they matter up high
Electrolytes are the minerals your body uses to hold water and keep muscles working — sodium, potassium, calcium and magnesium. On a climb you sweat and breathe them out faster than you take them in, and the result is the headache, cramps and drained feeling that come with altitude. A chew or tablet that lists all four minerals replaces more of what you lose than one leaning on a single salt.
Chewable versus capsule
A chewable tablet dissolves in your mouth and starts working quickly, which is what you want when a headache is already building and you have no water to mix a powder. A capsule is slower but easier to carry in bulk and simpler to take with a sip of water at a rest stop. Neither is better in the abstract — it depends on if you need speed or convenience on the day.
Ginger and the stomach side
Ginger is the herb most associated with settling an upset stomach and occasional nausea, and it carries compounds called gingerols. Altitude often turns the stomach before anything else, so a ginger capsule covers a symptom the electrolyte products do not touch. Look for a single-ingredient or USDA Organic product so the dose is mostly ginger rather than filler.
Dose timing on a climb
Most electrolyte chews are built to be taken at intervals through exertion — the SaltStick label, for instance, suggests chewing two tablets every 30 minutes while active and drinking water as needed. Ginger is usually taken ahead of a stomach turning rather than after. Reading the label and spacing doses keeps you covered without overdoing the sweeteners.

The Bottom Line
For most people heading up a mountain, the best of these supplements for altitude sickness is the Herbal Roots Organic Ginger Capsules — a USDA Certified Organic (grown and processed under strict government standards), single-ingredient ginger capsule that settles the nausea altitude brings on, with the crowd of buyers behind it. If salt loss is your bigger problem on the climb, the SaltStick FastChews get sodium and the other three electrolytes back in fast, no water required. And if your trip ends with a celebration, the DHM 1,000mg is the recovery tablet to keep in the pack for the morning after. Pick the ginger if nausea rules your climbs, the chews if it is the sweat — and carry both if altitude tends to hit you hard.
