Is Insufend worth it?
Worth a look (4.6/10). Insufend is a capsule sold as a natural fix for type 2 diabetes, built around the idea that a single pancreatic glucose sensor is the hidden cause of the disease and that fixing it removes the need for medication. That framing goes well beyond what is known about a complex, multifactorial condition. The label does name real doses for vitamin D3, B1 and chromium, which is better than many ClickBank supplements, but the remaining seven active ingredients, including cinnamon bark and gymnema, the two most studied for blood sugar, share a single 525mg proprietary blend, far below the doses used in the actual clinical research. At $69 to $69 a bottle before shipping, you are paying supplement prices for a formula that talks like a diabetes treatment but doses like an afterthought.
What we liked
- Vitamin D3, B1 and chromium are named with exact doses on the label
- Chromium dose falls within the range used in actual blood sugar research
- 60-day money-back guarantee stated on the sales page
- Free US shipping on the 3 and 6 bottle packages
What we didn't
- Markets itself as a way to treat type 2 diabetes without medication
- Cinnamon bark and gymnema, the two ingredients most tied to blood sugar research, are hidden in a 525mg blend far below studied doses
- "118,000 users" and "hundreds of reviews" are unverifiable claims
- No named company or refund address beyond an email and PO-style address on the label
- Standard crossed-out pricing and scarcity messaging inflate the sense of a deal
What is Insufend?
Insufend is a capsule supplement sold as a way to support healthy blood sugar in people with type 2 diabetes. The sales page opens with a story blaming diabetes on a single failed "glucose sensor" inside the pancreas's beta cells, and says Insufend repairs that sensor so the body can release insulin normally again, without drugs, diets or injections. One bottle holds 30 capsules, taken one a day, so one bottle covers 30 days.
The formula, according to the sales page and the product label, combines vitamin D3, vitamin B1 and chromium at stated doses, plus a 525mg proprietary blend containing Sukre prebiotic fiber, theobromine, green tea leaf extract, eleuthero root, TeaCrine (theacrine), cinnamon bark and gymnema sylvestris leaf. The page credits a named creator, Matthew Brown, though no company name, address beyond a support email, or professional credentials are given for him.
It is sold through ClickBank, which appears as the retailer on the card statement and handles order and refund support.
Format: Capsule, 30 per bottle, 1 a day. Sold by: InsuFend (sold through ClickBank).
What is on the Insufend label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
The label is a mix of two good practices and one common shortcut: D3, B1 and chromium are named with exact milligram amounts, but the two ingredients most associated with blood sugar research, cinnamon and gymnema, are buried inside a 525mg blend with five other ingredients, so neither reaches a dose close to what has been tested in trials.
Do the Insufend claims hold up?
"There's a reason why your diabetes keeps getting worse... a hidden problem inside your pancreas, a tiny but powerful glucose sensor that has stopped working properly"
Type 2 diabetes involves insulin resistance and progressive loss of beta cell function, a real and well-studied process, but it is driven by multiple factors (genetics, body weight, activity, diet) rather than one fixable "sensor." No study on Insufend itself, or on this specific mechanism being reversed by the ingredients listed, was found or cited on the page.
"InsuFend can [naturally regulate blood sugar] without drugs, restrictive diets, or painful injections"
This directly positions the product as a substitute for medical diabetes treatment. Type 2 diabetes is a diagnosed medical condition; changing or stopping medication without a doctor's involvement can be dangerous, and no clinical trial data on Insufend supports replacing treatment.
"More than 118,000 men and women have already proven it" and hundreds of reviews backing the guarantee
No source, survey or third-party verification is given for this customer count; it cannot be confirmed from the sales page.
A 30-item reference list of general diabetes and nutrition research, with a disclaimer that Insufend is not endorsed by any of them
The references cover general diabetes statistics, costs and background research on individual ingredients like cinnamon and gymnema. None is a clinical trial of the Insufend formula itself, and the page's own disclaimer confirms none of these sources endorses the product.
How much does Insufend really cost?
| Option | Total | Per month | Shipping |
|---|---|---|---|
| 1 bottle | $69 | $69 | +$9.99 US shipping |
| 3 bottles | $177 | $59 | Free US shipping |
| 6 bottles | $294 | $49 | Free US shipping |
The sales page lists three packages: 1 bottle for $69 (listed against a crossed-out $149) plus $9.99 shipping, 3 bottles for $177 ($59 a bottle) with free shipping, and 6 bottles for $294 ($49 a bottle) with free shipping. Since one bottle covers 30 days, that works out to roughly $69 to $79 for a single month, or $49 a month if you commit to six bottles up front.
The 3 and 6 bottle packages add two digital bonus guides (Stress Less and Secrets to Good Habits, each listed at a $59 value) that are unrelated to blood sugar and not a strong reason on their own to buy more bottles.
The crossed-out "original" prices ($149, $447, $894) are typical of this sales format and are not evidence of a real price history; treat the discount percentages as marketing rather than fact.
The sales page adds $9.99 shipping to a single bottle and offers free US shipping on the 3 and 6 bottle packages. No international shipping details were shown on the page.
Can you get a refund on Insufend?
60-day window. The sales page states a 60-day, no-questions-asked money-back guarantee in two places (the guarantee section and the FAQ). We could not reach a ClickBank order form directly, since the buy buttons are loaded by JavaScript rather than linked in the page HTML, so this figure comes from the sales page only.
Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.
Which red flags did we find?
- Frames a diagnosed disease as fixable without medical careThe pitch tells readers they can regulate blood sugar "without drugs" for a condition, type 2 diabetes, that is medically diagnosed and managed.
- Cinnamon and gymnema doses hidden in a small shared blend525mg split across seven ingredients is far below the single-ingredient doses used in the cinnamon and gymnema trials the category is based on.
- Unverifiable customer count"More than 118,000" users and "hundreds of reviews" are stated with no source to check.
- Reference list is general background, not product evidence30 links cover diabetes statistics and ingredient background, not a single trial of Insufend.
- Scarcity messagingThe FAQ says stock depends on "how long it will take to replenish" rare ingredients, a common urgency tactic with no supply data behind it.
Who should buy Insufend, and who should skip it?
It may suit you if
- You want to try a vitamin D3, B1 and chromium supplement alongside your existing diabetes care and are comfortable that the rest of the formula is an unproven, low-dosed blend.
- You are prepared to use the 60-day guarantee if the product does not deliver noticeable results.
Skip it if
- You are looking for a way to reduce or replace diabetes medication. Do not change a prescribed treatment without your doctor; this product has no clinical evidence to support doing so.
- You want cinnamon or gymnema at the doses used in research. A proprietary blend this small cannot deliver either at a meaningful level.
- You are on a tight budget. Six bottles up front is $294, and even the smallest single-bottle order runs about $79 with shipping.

Insufend FAQ
Is Insufend a scam?
It is a real supplement sold through ClickBank with a stated 60-day refund, so it is not taking money for nothing. The concern is the marketing: it frames type 2 diabetes as fixable without medication and hides its two most relevant ingredients in a small shared blend.
How much does Insufend cost?
One bottle (a 30-day supply) is $69 plus $9.99 shipping. Buying 3 bottles brings it to $59 a bottle and 6 bottles to $49 a bottle, both with free US shipping.
Can Insufend replace my diabetes medication?
No. Type 2 diabetes is a medical condition that needs a doctor's supervision. Insufend has no clinical trial of its own and should not be used as a substitute for prescribed treatment.
What are the side effects of Insufend?
The sales page does not list specific side effects, and its blend hides individual ingredient amounts, so a full safety picture is not available from the page. Anyone with diabetes should check with a doctor before adding any supplement, especially alongside blood sugar medication.
How do I get an Insufend refund?
The sales page says to email support within 60 days of purchase for a full refund. Because the order is processed by ClickBank, you can also start the request from your ClickBank receipt at clkbank.com.
