If you spend any time in wellness corners of the internet, you have probably seen raw potato juice show up as a cure-all for everything from acid reflux to inflammation. The nutrients in a potato are real. The specific claims made for drinking it raw, blended, unwashed of its own starchy grit, are mostly built on tradition and anecdote rather than solid clinical research. It is worth separating the two before you start juicing your grocery bag.
Key points
- Raw potatoes do contain real nutrients, including potassium, vitamin C, and resistant starch.
- Most of the specific health claims for raw potato juice are not backed by strong human research.
- Green or sprouted potatoes contain solanine, a compound that can be genuinely harmful.
- Eating potatoes cooked, as part of normal meals, gets you most of the nutritional benefit with far less risk.
What's in raw potato juice
A potato is a genuinely decent source of potassium, vitamin C, and B6, along with a type of starch called resistant starch that behaves a bit like fibre in the gut when the potato has not been cooked. Blend a raw potato with water and you do get some of those nutrients into a drinkable form.
That is a real, if fairly modest, nutritional profile. It is also one you can get from a baked or boiled potato, minus the unpleasant texture of drinking liquefied raw starch. The interesting part of the ingredient does not automatically make the specific practice of juicing it raw a health breakthrough. For a food-first routine built from ordinary ingredients rather than a single juice claim, use our low-effort meal-prep guide.
The reasons people give for drinking it, and how strong that evidence really is
- "It heals stomach ulcers." Some very small or older studies looked at raw potato extracts and ulcer models, but there is no strong modern human trial confirming raw potato juice treats ulcers reliably.
- "It reduces inflammation." Potatoes contain some polyphenols that may have mild antioxidant activity, but that is a long way from evidence that juice reduces inflammation in the body.
- "It detoxes the body." Your liver and kidneys handle detoxification. No juice, raw or otherwise, has been shown to add meaningfully to that job in healthy people.
- "It cures acid reflux." Anecdotal reports exist, but there is no solid clinical evidence that raw potato juice treats reflux better than standard approaches.
- "It's a natural resistant starch supplement." This one has a grain of truth, since raw starch does behave differently in the gut, though whole cooked-and-cooled potatoes offer a similar effect with a much more pleasant experience.
Notice the pattern: a plausible-sounding mechanism attached to a claim with almost no rigorous human evidence behind it. That gap is exactly where a lot of fringe wellness trends live.
Use this as a starting point, then adjust for your body, conditions and professional advice. A plan is useful only when it responds to you.
The real risks worth knowing before you try it
Green-tinged or sprouted potatoes contain solanine, a naturally occurring compound that can cause nausea, stomach cramps, and in larger amounts more serious symptoms. Cooking reduces solanine somewhat, but drinking a raw, unwashed potato juice made from a potato with green patches is a genuinely risky choice, not a wellness shortcut.
Raw starch can also be harder for some people to digest and may cause bloating or stomach discomfort, particularly if you jump straight to a large serving. Potassium content is worth a mention too, since anyone on medication that affects potassium levels, such as certain blood pressure or kidney medications, should talk to a doctor before adding a concentrated raw potato drink to their routine.
If a health issue like reflux or digestive discomfort is the real reason you are considering this, it is worth getting it properly assessed rather than self-treating with a fringe remedy. The health hub has more grounded reading on digestive and general health topics.
How to think about raw potato juice without falling for the hype
It is fair to be curious about a trending remedy, and it is also fair to stay skeptical when the claims outpace the evidence by this much. Potatoes are a solid, affordable food with real nutrients. Drinking them raw and blended does not give you some hidden power that cooking destroys. It mostly just makes the same modest nutrition harder to swallow, literally.
If you want the resistant starch benefit people talk about, cooking a potato and letting it cool before eating achieves something similar with far less risk and far more flavour. For a simple way to fit potatoes and other vegetables into a properly balanced plate, the Balanced Meal Builder is a more useful tool than a juicer for this particular goal. For more level-headed food reading like this, the food hub is worth a browse.
A trend having a devoted online following is not the same thing as a trend having good evidence behind it. Raw potato juice is a reasonable example of exactly that gap.
Should I try it?
You are better off eating potatoes cooked as part of a balanced diet, and speaking to a doctor first if you take medication affected by potassium intake.

Should You Really Start Drinking Raw Potato Juice? A Skeptical Look: questions answered
Is raw potato juice proven to help ulcers or inflammation?
+
No. There is no strong, modern human research confirming these specific claims, even though some small early studies looked at related ideas.
Is raw potato juice safe to drink?
+
Only if made from potatoes with no green patches or sprouting, and even then, moderation makes sense given the limited research on regular raw consumption.
