Study, Trial or Testing Result Summary

Members OnlyHuman studies

No study findings were provided for the ingredients in this product, and no human studies on gas, bloating or regularity were found for them. The store listing names sodium copper chlorophyllin, peppermint oil, alfalfa juice extract and barley grass juice extract. On the label, all of these sit inside a single proprietary blend of 43 milligrams per serving, so the amount of each ingredient is not disclosed. Because the doses are hidden in the blend, there is no way to compare them with doses used in any research. Peppermint oil is often linked with digestive comfort, but no findings on it were given here, so that link cannot be confirmed for this product. Buyer ratings are strongly positive overall. The written feedback that could be found focuses on the mild mint taste and the convenience of adding a liquid to water, not on measured digestive benefit. Members looking for help with gas, bloating or irregularity should know that support for this product rests on user satisfaction, not on study evidence for this goal. Animal and cell studies are never counted.

The feedback I could retrieve is limited and mixed, and much of it comes from Amazon Vine reviewers who received the product free. Taste and format got the most positive comments. One reviewer called the peppermint flavor mild and refreshing, and listings stress how easy it is to add to water for people who dislike pills. Other reviewers liked the product's convenience and its place in a daily "going green" routine. Another Spanish reviewer rated the format 5 out of 5 stars, which suggests that liquid, portable dosing appeals to people who want a simple habit. A Spanish reviewer also criticized the bottle design, saying it could be better made. That is a common complaint with large, pour-from-the-bottle supplements, where measuring and dripping can be messy. The negative feedback centered on texture and overall experience. One UK reviewer gave 1 out of 5 stars and called it a "liquid sludge." That points to a thick, dark, plant-heavy liquid that some people find unpleasant. Another reviewer called the product line a "mixed bag," meaning some elements worked for them and others did not. Because the mint flavor is described as mild, people who expect a strong mint taste or a clear breath-freshening effect may be disappointed. People who dislike earthy, grassy or "green" flavors may also be disappointed. Many eBay and Amazon comments are about the seller rather than the product. They praise fast shipping and careful packaging, which says little about how the supplement performs. I found no solid evidence in the sources I could read for the larger claims about detox, immunity or weight. Anyone drawn to those claims should treat them as marketing. I also found no detailed reports of side effects, though dark green stools and mild stomach upset are known with chlorophyllin generally. In short, buyers like the easy, mildly minty way to take a chlorophyll supplement. The complaints are about texture, bottle design and unclear benefits. Because the review base is thin, these themes are tentative.

Biohacker Summary

Members Only8 of 10 recommend it
8 of 10 biohackers on our panel recommend it

The statements say nothing about chlorophyll, the main ingredient in this product, so the panel gives no guidance on it. Peppermint and alfalfa are both smaller ingredients in this product, and peppermint drew the most comments: seven of the ten panelists spoke about it, mostly as an oil rather than a drink. They use or recommend it for gut trouble, gas and nausea, for alertness and headaches when sniffed or applied to the skin, and for mouthwash, toothpaste and hair care, with a few drops being the usual amount and tea mentioned by two. Two panelists warn that peppermint can relax the valve at the top of the stomach and make acid reflux worse. Alfalfa came up with three panelists, who mentioned alfalfa sprouts for blood sugar and pancreas health, plus skin care uses, and one suggested a cup or two a couple of times a week.

RAL Summary

Members OnlyTier 4 for Digestion and Bloating

Tier 3 needs some study support, but no human studies for this goal were found for any of its ingredients, so the evidence is thin and tier 4 applies. So it is graded Tier 4, lower than the rules alone gave.

  • Emerging: not enough evidence to rank higher yet.
  • No human studies on this goal for its ingredients.

Body systems: Digestive system

Combine with: For a real cellular and DNA repair focus, pair a chlorophyllin product with evidence-based ingredients such as NMN or nicotinamide riboside (NAD+ support), quercetin and fisetin (senolytic support), resveratrol or pterostilbene (sirtuin activation), CoQ10 or ubiquinol (mitochondrial support), and alpha-lipoic acid. Methylation cofactors such as methylfolate, methylcobalamin and TMG help DNA synthesis and repair. Vitamin D3 with K2, magnesium, zinc and omega-3 fatty acids support general cell health. For digestive and deodorizing uses, chlorophyllin goes well with a probiotic, digestive enzymes, fiber such as psyllium, and ginger or additional peppermint oil for bloating comfort. Take copper-containing chlorophyllin with water and consult a clinician if you are pregnant, have Wilson's disease or take photosensitizing medications.

Possible side effects: No side effects were reported in the feedback that could be read. The review summary notes that dark green stools and mild stomach upset are known with chlorophyllin generally.
