PectaSol Review: The Trial Used 14.4 g a Day. The Bottle Has 1.
Key takeaways
- The phase II dose was 4.8 g three times daily — 14.4 g a day, for 6 months and then a further 12.
- PectaSol Detox Formula's own label provides 1 g of PectaSol-C per serving. One fourteenth of the studied dose.
- The study was single-arm with no control group, and the endpoint was PSA dynamics, not survival or metastasis-free survival.
- The paper's conflict-of-interest statement records that one author is the developer of the sponsoring supplement company.
- Reported results at 18 months in 39 men: 85% durable response, 62% decreased/stable PSA, 90% PSADT improvement, negative scans, no grade 3/4 toxicity.
- No affiliate link on this page. Taking a commission on a cancer-adjacent supplement is not something this site will do.
Most supplement reviews on this site begin by finding that the evidence is thinner than the marketing. This one does not, and it is worth saying so first.
Modified citrus pectin has been studied in an actual oncology setting, prospectively, across hospital departments, with published results in a peer-reviewed journal.
The problem is not the absence of evidence. It is the distance between the evidence and the bottle.
What the study actually did
A prospective phase II study, run through oncology and urology departments at Israeli medical centres, treated men with non-metastatic biochemically relapsed prostate cancer — men whose PSA had risen after local treatment, with no metastases visible on scans.
The dose was 4.8 g three times a day: 14.4 g daily.
An initial six-month phase reported PSA doubling time improvement in 75% of patients. Men without progression continued for a further 12 months, and the long-term results were published in Nutrients in 2023.
After 18 months, of the 39 men who began the extension:
| Outcome | Result |
|---|---|
| Durable long-term response | 85% (n=33) |
| Decreased or stable PSA | 62% (n=24) |
| PSADT improvement | 90% (n=35) |
| Scans | all negative |
| Grade 3/4 toxicity | none |
Those are not trivial numbers and this page is not going to pretend they are.
The three things attached to them
There was no control group. The study was single-arm. Nobody was compared against men taking nothing, and PSA doubling time moves on its own — which is precisely what a control arm exists to account for. Without one, you cannot separate the supplement from the natural course.
The endpoint was PSA behaviour, not survival. PSA dynamics are a marker. Improving a marker and living longer are different claims, and only the first was measured.
One author developed the product. The paper’s own conflict-of-interest statement reads:
I.E. discloses being the developer of the sponsoring dietary supplement company but holds no ownership in the company.
Disclosed properly, which is how it should be. It is still a fact that belongs in any honest summary.
None of this makes the results wrong. It makes them preliminary — which is what phase II means, and phase II is where a great many promising findings stop.
Now the number that matters if you are shopping
The product most people will find and buy is PectaSol Detox Formula, listed from $49.95. Its own Supplement Facts panel:
| Per 2 capsules | |
|---|---|
| Algimate® modified alginate complex | 500 mg |
| PectaSol-C® modified citrus pectin | 1 g |
And the company’s product page states it plainly: the formula provides 1 gram of PectaSol per day.
Trial dose: 14.4 g / day
Retail bottle: 1.0 g / dayOne fourteenth.
Reproducing the trial protocol from this product would mean roughly 28 capsules a day, and a bottle lasting two days.
And it is sold for something else
The Detox Formula is not marketed as the oncology protocol. It is marketed for binding heavy metals — the page cites increased urinary excretion of cadmium and lead — and it pairs the pectin with an alginate complex for that purpose.
Those are separate claims about a separate use, and this review does not assess them. The point for anyone who arrived here after reading about the prostate study is simply this: that study is not what is in this bottle, at this dose, for this stated purpose.
Why there is no buy button on this page
This site runs affiliate links. They are disclosed, and they appear where a product follows from what the page concluded.
Here the page concluded that the retail product contains a fourteenth of a studied dose, from a single-arm trial, in a disease context. The people most likely to be reading this have a cancer diagnosis.
We are not taking a commission on that. Refusing is worth more to you than a button would be, and it is the same position we take wherever the evidence does not support a purchase.
If this is personal
If you are here because of a prostate cancer diagnosis or a rising PSA, take this page to your oncologist rather than acting on it.
What it gives you for that conversation is the specifics: the trial exists, the dose was 14.4 g a day, it was uncontrolled, it measured PSA rather than survival, the developer was an author, and the retail product is a fourteenth of the dose. A specialist can weigh those against your actual situation, which no article can.
Nothing here is medical advice, and no supplement should displace or delay treatment that has been recommended to you.
Frequently asked questions
Does PectaSol have real clinical evidence?
More than most supplements, and it should be said plainly before anything else. A prospective phase II study run across Israeli oncology and urology departments treated men with non-metastatic biochemically relapsed prostate cancer with PectaSol modified citrus pectin at 4.8 g three times a day. An initial six-month phase reported PSA doubling time improvement in 75% of patients. In the long-term phase published in Nutrients in 2023, 39 men began a further 12 months, and after 18 months in total 85% had a durable long-term response, 62% had decreased or stable PSA, 90% showed PSADT improvement, all had negative scans and no patient experienced grade 3 or 4 toxicity.
What are the limitations of that study?
Three, and they are not small. First, it was single-arm: there was no control group, so there is no comparison against men who took nothing. PSA doubling time varies on its own, which is exactly what a control arm exists to account for. Second, the endpoint was PSA dynamics rather than metastasis-free survival or overall survival — PSA behaviour is a marker, and improving a marker is not the same as living longer or avoiding metastasis. Third, the published conflict-of-interest statement records that one author is the developer of the sponsoring dietary supplement company, though it states he holds no ownership in it. None of that makes the results false. It means they are preliminary, which is what phase II means.
How much PectaSol is in the product I would buy?
One gram a day, and this is the number the review turns on. PectaSol Detox Formula's own Supplement Facts panel lists PectaSol-C modified citrus pectin at 1 g per two-capsule serving, alongside 500 mg of an Algimate modified alginate complex, with 30 servings per bottle. The trial dose was 14.4 g a day. So the retail product delivers roughly one fourteenth of what was studied, and matching the trial from this product would mean taking about 28 capsules a day.
Is the Detox Formula even the same thing?
The ingredient is the same branded material — PectaSol-C — but the product is sold for a different purpose. The Detox Formula is marketed for binding heavy metals, and the company's page cites figures for increased urinary excretion of cadmium and lead. Those are separate claims about a separate use, and this page does not assess them. What it establishes is narrower and more useful to anyone who arrived here from prostate cancer research: the oncology study used a much higher dose of the same ingredient, and the detox product is not that protocol in a bottle.
Why is there no affiliate link on this page?
Because of what the subject is. This site does carry affiliate links, disclosed, on pages where a product follows from the conclusion. Here the conclusion is that the retail product provides a fourteenth of the studied dose, and the people most likely to search for this have a cancer diagnosis. Earning a commission on that is not something we are willing to do, and saying so is more useful to you than a buy button would be. We have taken the same position on other pages where the evidence did not support a purchase.
Is modified citrus pectin safe?
In the study described here, no patient experienced grade 3 or 4 toxicity over 18 months at 14.4 g a day, and the paper notes that PectaSol-MCP is categorised as GRAS — Generally Recognized As Safe — by the FDA. That is a reasonable safety signal. It is not a reason to self-prescribe it at trial doses, because the men in that study were under oncological supervision with regular PSA monitoring and imaging, which is the part of the protocol that a bottle does not come with.
I have prostate cancer. What should I do with this page?
Take it to your oncologist rather than acting on it. What this page gives you that a product page will not is the specifics you need for that conversation: the trial, the dose, the fact that it was uncontrolled, the endpoint it measured, and the gap between the studied dose and the retail one. Those are the things a specialist can weigh against your own situation. Nothing here is medical advice, and no supplement decision should displace or delay treatment that has been recommended to you.
