★★★★★
“I stopped grazing after dinner somewhere in week three. Not a switch flipping, just less reaching for the cabinet. Down eleven pounds at the four month mark and my rings fit again.”

AlkaSlim Reviews (2026): 8,431 Verified Buyers
4.68 out of 5
★★★★★
Based on 8,431 verified AlkaSlim buyers, of whom 1,109 left written feedback.
On the name. AlkaSlim has been sold under the label CitrusBurn since June 2026, after a competing claim over the name. Ordering, pricing, the lot record and the 180-day promise all run through this portal exactly as before. The full rename notice is on the home page.
Read this before the numbers. The great majority of these 1,109 reviews were written about the original fiber-led AlkaSlim formula, before the June 2026 relaunch as CitrusBurn. They are honest about that product. Reviews of the reformulated, thermogenic label are still a small minority of the total, so treat the aggregate as history rather than as a verdict on the bottle shipping today.
Start here
Across 8,431 verified buyers as of 2026, AlkaSlim holds 4.68 out of 5. The most-reported outcome is smaller portions at dinner, named by 44% of written reviews, and 86% of reviewers say they would recommend it. The most common complaint is speed: the median reviewer describes a first noticeable change around week three or four, not week one.
Two paragraphs on how to read these AlkaSlim reviews. Every figure on this page comes from our own order and support records, not from a third-party widget, and every review is attached to a completed order placed through the AlkaSlim official website. Reviews that we could not tie to an order were excluded, which is where the 97% verified-purchase figure comes from.
The pattern has been stable. Between 2025 and 2026 the average rating moved by less than a tenth of a point while volume roughly doubled, which usually means a product is finding the right buyer rather than riding a launch. The dominant story in the text is not dramatic weight loss. It is people describing a quieter evening appetite and being surprised that a capsule with nothing stimulating in it did anything at all.

AlkaSlim star distribution
| 5 stars | 73% | |
|---|---|---|
| 4 stars | 18% | |
| 3 stars | 6% | |
| 2 stars | 2% | |
| 1 star | 1% |
Nine percent of AlkaSlim reviewers gave three stars or fewer, and we leave every one of them up. Read those first if you are deciding. The recurring theme among them is not that AlkaSlim did something unpleasant, it is that it did less than the reviewer hoped inside the time they gave it. Almost all of them mention that the refund went through without an argument, which is the part we can control.
Who is buying AlkaSlim
| Age | Share |
|---|---|
| 18 to 34 | 9% |
| 35 to 44 | 21% |
| 45 to 54 | 32% |
| 55 to 64 | 26% |
| 65 and over | 12% |
| Region | Share |
|---|---|
| South | 34% |
| Midwest | 27% |
| West | 22% |
| Northeast | 17% |
| Bundle | Share of orders |
|---|---|
| 6-bottle bundle | 47% |
| 3-bottle bundle | 36% |
| Single bottle | 17% |
The AlkaSlim age skew is the least surprising thing in the dataset. Two thirds of buyers are between 45 and 64, which lines up with who went looking for a stimulant-free option while that was what AlkaSlim offered. The bundle split is more interesting: nearly half take the six-bottle bundle on a first order, which suggests the 180-day promise is doing real work at the decision point.
What AlkaSlim reviewers mention most
| Smaller portions at dinner | 44% | |
|---|---|---|
| Less snacking after 8pm | 38% | |
| Steadier afternoon energy | 31% | |
| Easy to remember, one capsule | 29% | |
| More regular digestion | 26% | |
| Clothes fitting differently | 22% | |
| No jitters or sleep problems | 19% |
What reviewers complain about
| Took longer than expected | 11% | |
|---|---|---|
| Wanted milligram amounts on the label | 8% | |
| Mild bloating in the first week | 5% |
The bloating figure is worth a note. When we follow up, most of those reviewers were taking AlkaSlim with a small amount of water. A swelling fiber needs a full glass, and the complaint largely disappears in the second week once people adjust.
How long until AlkaSlim does something
| Under 1 week | 8% | |
|---|---|---|
| 1 to 2 weeks | 21% | |
| 3 to 4 weeks | 37% | |
| 5 to 8 weeks | 26% | |
| Over 8 weeks | 8% |
Two thirds of reviewers land in the three to eight week band. This is the single most useful number on the page, and it is the reason the refund window runs 180 days.
Review volume by quarter
| Q2 2025 | 118 written reviews |
|---|---|
| Q3 2025 | 147 written reviews |
| Q4 2025 | 181 written reviews |
| Q1 2026 | 226 written reviews |
| Q2 2026 | 274 written reviews |
| Q3 2026 to date | 163 written reviews |
Volume has grown steadily while the average rating held between 4.66 and 4.71 across 2025 and 2026. A rating that stays flat as volume doubles is a better signal than a high rating on forty reviews.
Featured AlkaSlim reviews by buyer type
Fifteen reviews chosen to represent the middle of each group rather than the best of it. Names are shortened at the reviewer's request, ages and cities are as given at checkout.
Women over 50 rebuilding a routine
★★★★★
“Menopause turned my appetite into someone else's. This is the first thing in two years that made portions feel like my decision again. I take it with breakfast and forget about it.”
★★★★☆
“Six weeks before I noticed anything, which honestly nearly made me quit. Glad I did not. The refund window being so long is the only reason I stayed long enough.”
Men who bounced off stimulant formulas
★★★★★
“I have tried the caffeine pills and they made me feel awful by 2pm. This one I genuinely forget I took, which after two months I decided was the point.”
★★★★★
“No racing heart, no crash, no weird sweating at my desk. My wife noticed the change in my plate before I did. Ordered the six bottle bundle the second time.”
★★★★☆
“Does what it says on portions. Do not expect fireworks. I lost about seven pounds over three months while walking most evenings, and I am fine with that number.”
Shift workers and irregular schedules
★★★★★
“Nights on the floor at the hospital wreck my eating. Taking one capsule before the shift with a big bottle of water stopped the 3am vending machine habit almost entirely.”
★★★★☆
“Rotating shifts, so consistency is hard. It still helped, just slower than the reviews suggested. Support was quick when I asked whether timing mattered.”
★★★★★
“Two under five and no time to think about food. This is the least demanding thing I have added to my day and the only one I have kept past a month.”
People coming off a plateau
★★★★☆
“Slower for me than the reviews suggested, maybe six weeks before anything. Support answered on the first email when I asked about the lot code, which is more than I expected.”
★★★★★
“Stuck at the same number for a year. Not a miracle, but the last eight pounds finally moved once the evening eating stopped. I credit the fiber more than anything mystical.”
★★★★★
“Bought two bottles expecting nothing. Reordered six. It is not dramatic and that is why I trust it.”
Long-term users past six months
★★★★★
“Eight months in. The first two were the interesting ones, and since then it is just part of the morning. Weight has stayed where it landed, which was the actual goal.”
★★★★★
“I keep buying it because stopping for a month in the spring told me it was doing something. Straight back to snacking within a fortnight.”
★★★★☆
“Two years on the old label, three months on the new one. The citrus version is stronger and I feel it, which I did not expect to like. Docking a star because nobody told me it now has caffeine in it until I read the label myself.”
The critical reviews, kept in full
These are two and three star reviews. We publish them because a page with no criticism on it tells you nothing.
★★★☆☆
“Eight weeks and I got the digestive side but not much on appetite. Emailed for a refund on day fifty-one, money back in six days, no argument and they did not ask me to ship the opened bottles back.”
★★☆☆☆
“Bloated for the first ten days and never really settled. Possibly on me for not drinking enough water with it. Refund was processed without a fuss, which is the only reason this is two stars and not one.”
★★★☆☆
“It worked but slowly, and I wanted more from six bottles. Returned four unopened and two opened and got the full amount back. Fair company, product just was not for me.”
What the timeline usually looks like
Week one. On AlkaSlim, digestion settles first. Most people report nothing about appetite yet, and a minority report mild bloating that resolves once they increase the water they take the capsule with.
Weeks two and three. The evening habit is the first thing AlkaSlim reviewers report moving. Reviewers describe finishing dinner and not going looking for something afterwards, which they often notice retrospectively rather than in the moment.
Weeks four to six. AlkaSlim portion sizes shift and clothes are the second thing mentioned, ahead of the scale. This is where most three-star reviews would have become four-star reviews if the reviewer had stayed.
Past two months. Long-term reviewers describe AlkaSlim as maintenance rather than change. Several mention stopping for a month and noticing the old snacking pattern return, which is the most common reason people reorder.
What helped most, and what helped least
The single strongest correlation in the written AlkaSlim reviews is water. People who describe taking the capsule with a full glass report the appetite effect at roughly double the rate of people who do not mention water at all. The second is timing consistency: same time daily beats whenever-I-remember by a wide margin in the text, even though the label does not specify a time.
What helped least, judging by the disappointed reviews: expecting AlkaSlim to work against an unchanged diet. The reviewers who report the largest changes almost always mention a second thing they did, usually walking. We would rather say that than let you find out at day fifty.
Are these AlkaSlim reviews trustworthy?
Every AlkaSlim review here is tied to a completed order in our own system, which is the only verification we can honestly claim. We do not buy reviews, we do not filter by rating, and we do not remove a review because it is unflattering. What we do remove is anything with a name we cannot match to an order, which is why the verified-purchase share is 97% rather than 100%.
You will not find genuine AlkaSlim reviews on Amazon or eBay, because we do not sell there. Any review attached to a marketplace listing is attached to a bottle we cannot trace. That matters for the same reason the lot code matters, and you can check yours on the verification page.
