AppleActiv® (Dried Apple Peel Polyphenols — Leahy Orchards)

Malus domestica
Evidence Level
Preliminary
0 Clinical Trials
3 Documented Benefits
1/5 Evidence Score

AppleActiv® is a dried apple peel powder (DAPP) from Leahy Orchards, capturing the polyphenol-rich peel that is usually discarded. Apple peel holds several times the polyphenols of the flesh, including quercetin and ursolic acid, and AppleActiv is marketed for joint comfort and antioxidant support. The two trials cited on this page fed whole apples rather than this dried peel powder, and the third reference is a review of apples and apple foods. Neither trial measured a joint outcome. Independent clinical evidence for AppleActiv itself is still limited.

Studied Dose No cited study established a dose for AppleActiv. A few hundred milligrams of apple peel polyphenols per day is a typical label amount rather than a researched dose, and the two cited trials fed whole apples as food.
Active Compound Dried apple peel powder rich in polyphenols, flavonoids, quercetin, triterpenoids (ursolic acid), and pectin fiber.

Benefits

Joint comfort reported in an uncited pilot

A company-sponsored 12-week pilot study reported that apple peel polyphenols supported joint comfort and range of motion. That pilot is not among the references on this page, and none of the cited studies measured joint comfort, stiffness, or range of motion. Independent confirmation is still limited.

Antioxidant support

Apple polyphenols behave as antioxidants in laboratory testing. The human evidence cited here comes from two randomized trials in adults with overweight and obesity that fed whole apples and measured inflammatory markers, not from trials of apple peel powder.

Anti-inflammatory polyphenols

Quercetin and ursolic acid have been studied in laboratory work for their effects on inflammatory enzyme activity. That is a mechanism rather than a demonstrated result, and no cited study tested it in people taking apple peel powder.

Mechanism of action

1

Polyphenol antioxidant action

Apple peel flavonoids and quercetin scavenge free radicals in laboratory assays. Whether a daily dose of apple peel powder changes antioxidant status in people has not been tested in the studies cited here.

2

Anti-inflammatory enzyme modulation

Apple peel compounds have been studied in laboratory models for effects on inflammatory enzymes such as COX-2 and lipoxygenase. This laboratory work is the basis of the joint-comfort positioning, and no human study cited on this page has tested it.

Clinical trials

Daily consumption of whole apples lowered plasma inflammatory biomarkers and those secreted by peripheral blood mononuclear cells. The exposure was whole apples eaten as food rather than AppleActiv dried apple peel powder, and no joint outcome was measured.
