Short answer: we cannot verify the claims made about Inmit Fasting Powder, and neither can you from the information publicly available. There are no published clinical trials on the product, independent reviews are scarce, and the marketing claims made for it are the same ones made for most supplements in this category. This page explains what is actually knowable, and how to judge products like it.
What Inmit Fasting Powder Claims to Be
Inmit is marketed as a powder to take during intermittent fasting windows, intended to supply electrolytes and fibre while suppressing appetite. Its marketing describes it as vegan, dairy-free, gluten-free, non-GMO and free from added sugar, and lists ingredients including Sunfiber (a guar-derived soluble fibre), green coffee extract, B vitamins and minerals such as calcium, magnesium, sodium, potassium and phosphorus.
Those are the manufacturer’s descriptions. We have not independently tested the product, and we are not affiliated with it.
The Claims That Should Make You Cautious
An earlier version of this article repeated several marketing claims uncritically. We have removed them, and it is worth explaining why, because you will see the same claims on many competing products.
- “100% natural, so no side effects.” This does not follow. Plenty of natural substances cause side effects and interact with medication. Green coffee extract contains caffeine, which affects sleep, anxiety and blood pressure in some people. Concentrated soluble fibre can cause bloating, cramping and gas, particularly when introduced suddenly. “Natural” is a marketing word, not a safety category.
- “Safe for anyone.” No supplement is safe for everyone. Anyone pregnant or breastfeeding, taking prescription medication, or living with diabetes, kidney disease, heart conditions or an eating disorder needs individual advice before adding a supplement — particularly one containing electrolytes and stimulants.
- “Increases lifespan.” No supplement has been shown to extend human lifespan. This claim was removed outright.
- “Speeds up fat burning” and “makes calories go to muscle instead of fat.” Nothing in a powder redirects calories. Green coffee extract had a wave of popularity built on weak and later-discredited research; the evidence for meaningful weight loss is poor.
- “Controls blood pressure and blood sugar.” These are medical claims. A supplement that genuinely did this would be a drug, and would be regulated as one.
How Supplements Are Actually Regulated
This is the piece most product reviews leave out, and it changes how you should read every claim on a supplement label.
In the United States, dietary supplements are not approved by the FDA before they go on sale. Manufacturers are responsible for their own safety and labelling, and the FDA generally acts only after a product is already on the market and a problem emerges. That means:
- “FDA registered facility” is not FDA approval of the product.
- No agency has verified that the contents match the label unless the product carries independent third-party certification, such as NSF or USP.
- Structure-function claims (“supports metabolism”) are permitted without proof of effect; disease claims (“controls blood pressure”) are not, and their presence is itself a warning sign.
So Is Inmit Legit or a Scam?
Neither label fits the available evidence, and we are not going to pretend otherwise to give you a cleaner answer.
- No evidence it is a scam: it appears to be a real product with a real ingredient list, sold through mainstream retailers.
- No evidence it works as advertised either: there are no published clinical trials on the finished product, and independent user reviews are thin enough that they cannot support a conclusion.
- The ingredients are unremarkable: electrolytes, soluble fibre and B vitamins are cheap and widely available. Whether they justify a supplement price is a personal call.
Our position: there is no reason to assume it is dangerous, and no good reason to expect it to produce weight loss on its own. If you are fasting and want electrolytes, plain water with a pinch of salt, or a basic electrolyte tablet, does much the same job for less.
Before You Try Any Fasting Supplement
- Speak to your doctor or a registered dietitian first, especially if you take medication or have a health condition. Fasting itself is not appropriate for everyone.
- Look for third-party testing — NSF Certified for Sport or USP Verified means someone independent checked what is in the tub.
- Read the full ingredient list, including the caffeine content if there is any.
- Treat testimonials as marketing. Before-and-after photos on a seller’s own site are not evidence.
- Be wary of any product promising results without dietary change. Appetite suppression is not the same as nutrition.
If you are considering fasting itself, our guide to what the research shows about intermittent fasting covers the evidence without the supplement.
Who Should Avoid It
Do not use fasting supplements, and speak to a doctor before fasting at all, if you are:
- Pregnant or breastfeeding
- Under 18
- Living with diabetes, particularly if you use insulin
- Managing kidney or heart conditions, where added electrolytes matter
- Living with, or recovering from, an eating disorder — appetite suppressants and fasting protocols can worsen restrictive patterns
Bottom Line
Inmit Fasting Powder is not obviously a scam, but there is no published evidence that it does what its marketing says. The claims we found most often repeated about it — natural therefore safe, no side effects, speeds fat burning, increases lifespan — do not stand up. Ask your doctor, look for third-party testing, and remember that no powder replaces the basics.
Frequently Asked Questions
A powder marketed to be taken during intermittent fasting windows, containing soluble fibre, electrolytes, B vitamins and green coffee extract. It is a dietary supplement, not a medicine.
Nobody can tell you that in general terms. Supplements are not FDA-approved before sale, and safety depends on your own health and medications. Green coffee extract contains caffeine and concentrated fibre can cause digestive upset. Ask your doctor or pharmacist before using it.
There is no published trial on the product showing that it does. Any weight change during intermittent fasting is far more likely to come from the fasting and overall diet than from a powder. No supplement replaces dietary change.
No. Natural substances can cause side effects and interact with medication. The phrase has no regulatory meaning and tells you nothing about safety.
Look for independent third-party certification such as NSF or USP, a full ingredient list with amounts, no disease claims, and published research on the actual product rather than on one ingredient in isolation.
Last updated: August 2026. This article is general information, not medical advice, and is not an endorsement of any product. We have no commercial relationship with Inmit. Talk to your doctor, pharmacist or a registered dietitian before starting any supplement or fasting protocol, particularly if you take medication, are pregnant, or have a health condition. If food, weight or fasting has started to feel controlling, that is worth raising with a professional.
