Olive Polyphenol Extract

Organic Fruits & Leaves

100% Solvent-Free

TruOliv™ is derived from TRUE olive fruits & leaves, NOT olive wastewater…

TruOlivis a USDA and EU organic, Kosher and Halal-certified solvent-free powder extract uniquely derived from TRUE olive fruits and leaves. TruOliv™ boasts a profile that simulates the quality, synergistic composition and efficacy of high-quality extra virgin olive oil, with 10% total polyphenols, consisting of ~ 2% hydroxytyrosol, 6% oleuropein, and measurable amounts of other synergistic phenols, like tyrosol, oleacin and olecanthal and flavonoids such as luteolin,  using a purely mechanical process. Further, by retaining a diverse spectrum of olive polyphenols, as found in table olive/olive oil’s traditional intake, synergism unknown to isolated hydroxytyrosol or oleuropein olive ingredients becomes uniquely availed by this brand.. The novelty and potency of TruOliv™ – as a concentrated, organic source of synergistic antioxidants – is of significant value in that it affords similar benefits as have been associated with olive oil consumption, but without the high-caloric intake and bitter taste thereof.

TruOliv delivers clinically validated results are in the areas of blood sugar and blood lipid support, joint health, and in-vitro models have validated it’s antimicrobial and anti-proliferative roles. The olive tree is known in traditional herbal medicine for the benefits afforded by both its leaves and fruit. TruOliv brings these actives together in one extract. Harvesting of the olives and their leaves begins in their young stages, along the growth spectrum, including the matured crop, so that a full profile of actives are collected.

The whole olive fruit and its leaves are utilized in TruOliv™, which distinguishes it from competitor olive products that use waste water remains from commercial olive oil production, solvents or other other unnatural/chemical processes. As such, a single dose of TruOliv delivers the polyphenol potency (in HT equivalents) of nearly 1.25 cups (~20 tbsp.) of olive oil. As it delivers this quantity in its natural matrix, devoid of solvents or processing, TruOliv™ is truly, a food-state/whole food ingredient.

TruOliv™ is enriched by the desert, NOT chemical reactions or solvents…

Native to the arid and extremely rocky terrain of the Moroccan deserts, the TruOliv ingredient is naturally enriched by its harsh terrain, allowing for the stress-induced production of high levels of polyphenols. Characteristics of this desert enriching process include:

  • Arid, (140ᴼ+ in direct sun) rocky conditions
  • Low quality water; high salinity due to excess evaporation
  • Olive pit hardening phase at greatest risk for thermo-evaporative threat
  • Signals stress mechanism, including activation of phenolic biosynthetic pathway (PAL)
  • Phenylalanine ammonia lyase (PAL) activation increases polyphenol synthesis
  • Results in high levels of concentrated polyphenols


TruOliv™ is 100% USDA and EU Organic Certified

TruOlivundergoes a solvent-free manufacturing processing that retains the potency of the olive leaf and fruit polyphenols. The use of physical instead of chemical extraction additionally complements the pristine desert conditions its source material grows in, allowing for market distinction as a certified USDA and EU organic extract. Four generations of preserved olive growing traditions have fueled the development of this potent ingredient and its clinical profile.

TruOliv™ is 100% derived from the olive tree. Proprietary concentrations of olives at varying stages of maturity along with both baby and adult leaves are collected and processed without heat or solvents to deliver an enriched powder extract, standardized to Hydroxytyrosol, oleoropein, and a spectrum of 13 other olive polyphenols, collectively characterized as Total Polyphenols.  


The olive leaf and fruit and their derived phenolics including hydroxytyrosol, have shown no adverse effects in published studies. In clinical studies for joint support and blood sugar management, profiles for kidney and liver function throughout the trials of 8 and 14 weeks, respectively showed no concern for safety. This, plus previous scientific inquiry into the safety of constituents found in TruOliv supports its use in dietary supplement formulations.

Clinical Research

Joint Health Support

TruOliv™ was trialed for its joint support benefits in a 90-person, 8-week double-blind, randomized placebo-controlled study in drug-naïve, ACR-diagnosed Rheumatoid Arthritis suffers of > 1 year. TruOliv™ supplementation, confirmed by elevated urinary HT output, resulted in a highly significant decrease of IL-6, TNF-α, hs-CRP and PGE2 (p < 0.0001), over placebo. Further, TruOliv™ resulted in a 1.37 mg/L reduction in hs-CRP (p < 0.0001). After 8 weeks, there was an approximately 35% reduction in pain intensity, and DAS-28 scoring for the TruOliv™ group (↓ 1.23; p < 0.0001). Whereas weight and PUFA (ϖ-3) intake over the 8 weeks remained stable and low diet scoring showed non-compliance to the Mediterranean diet, all inflammatory-modulating benefits were associated with the intake of TruOliv™.

Blood Sugar Support

A 14-week, 80-person clinical investigation into the cardio-metabolic effects of daily supplementation with TruOliv™ was undertaken using a randomized, double-blind, placebo-controlled design. Non-smoking, ADA-diagnosed, non-insulin dependent Type-2 diabetics of both genders were selected for this study. Marked urinary HT excretion over placebo confirmed TruOliv™ intake. Whereas more than half (˃50%) of both groups had baseline HbA1C levels >7 (7.79 and 7.46 intervention and placebo group, respectively), the actives group showed a 20% reduction in HbA1C (↓1.3) vs. increase of 1.4 in the placebo group (p < 0.0001). Further, fasting glucose level of the treated group was normalized by the end of the study, as per the ADA (114.2 ± 15.2 mg/dL). Insulin resistance improved (p < 0.0002), as did lipids (TC, TG, LDL) vs. placebo (p < 0.0001). Even without diet or exercise modifications, HDL levels increased by 5.1 mg/dL (p = 0.007).


Q: What makes TruOliv a ‘full spectrum’ extract?

A: TruOliv™ utilizes the whole olive fruit and leaf and does not process them under any chemical or synthetic reactions. Because many of olive’s polyphenols are very similar in chemical structure, the use of imposed chemical reactions can discriminately  concentrate levels of interest polyphenols, while sacrificing others found in a more natural spectrum. Extra-virgin olive oil (EVOO) is prepared from table olives by a purely physical process. Approximately, 36 polyphenols have been identified in olive oil as a result.

Four-generations of olive expertise informs a patent-pending prescription for producing TruOliv™, which includes the chronology of olive and leaf harvesting, their ratios and concentrations, which actualizes the ‘full spectrum’ dynamism of TruOliv™. Our testing confirms the presence of nearly 1/3rd* of all the polyphenols that are known to exist in EVOO.

*Note: TruOliv™ shows measurable levels of all polyphenols that are available in the testing panel.

Q: What are the benefits of using the leaf and fruit vs. waste water or only fruit or only leaf?

A: Olive waste water is a natural byproduct of olive oil production. Previous to the oil separation phase, olives undergo crushing and mixing with water. Because many of the polyphenols are hydrophilic, many of them remain in the water. However, as olive oil is produced from mature olives, which have autogenously (within the olive) converted the majority of native oleuropein, characteristic of the immature fruit – the waste water reflects this same profile: high levels of hydroxytyrosol, with little to no oleoropein.

The commercial products of waste water extract, also generally undergo a solvent-extraction step to further purify and concentrate HT. Using the leaf and whole olive fruit, allows for a characteristic blend of polyphenols that are synergistic, and further the solvent-FREE process avails these polyphenols in a chemical-free, organically-certified format.

Q: What is unique about TruOliv’s growing conditions?

A: TruOliv™ olives and leaves are grown in the Saharan desert of Northern Africa (Morocco). The olives and leaves grown in these conditions endure extreme stress and as a result, natuarally produce olives with higher polyphenols concentrations. Polyphenols are secondary metabolites of plants, and while they are useful adjuncts to the human diet, they are crucial components to a plant’s survival.

Desert conditions are extreme conditions, to which only the most resilient of plants can survive. Studies investigating this phenomenon have helped to uncovers some of the involved mechanisms, including the activation of phenalylanine lyase, a polyphenol production catalyst using simulated desert conditions, such as Regulated Deficit Irrigation practices.

Q: Is the product standardized?

A: YES. Although the TruOliv™ does not undergo solvent or hydrolysis reactions and is 100% pure olive fruit and leaf derived it is not a simple powder of these dried materials. The use of physical extraction techniques and desert enrichment results in an extract that is 10% Total Polyphenols, 6% Oleuropein, and 2% Hydroxytyrosol.

Q: What makes the product more bioavailable?

A: Because the product is made using the whole fruit, there are trace amounts of olive oil incorporated in the product. Independently done bioavailability studies on olive polyphenols, i.e. hydroxytyrosol show that HT is more bioavailable in a lipid medium, than when found in a purely aqueous medium.

Q: Why not just consume olives/olive oil?

A: You would have to consume 20+ tablespoons of olive oil (approximately 1.25 cups), which would result in over 3,000 calories just from fat (nearly 2 days worth of food), to receive just the Hydroxytyrosol quantity found in a suggested daily dose of TruOliv™. This quantity does not additionally take into consideration other synergist polyphenols.
