A new method of using Nuclear Magnetic Resonance (NMR) to directly measure compounds such as oleocanthal and oleacein has been revolutionary in the EVOO market. Up until the development of the NMR analysis, many of the EVOO health benefits were credited to the presence of monosaturated fat - as endorsed by the widely accepted Mediterranean Diet.
However, the NMR technique made it possible to measure and identify phenolic compounds that provide additional health benefits found only in high phenol EVOO. Scientific studies so far have suggested that oleocanthal and oleacein act as a natural anti-inflammatory agents that protect cells from the oxidation process (which leads to premature aging and disease). And while the benefits continue to be better understood, many studies have supported that oleocanthal and oleacein may even help fight against several cardiovascular and neurodegenerative diseases such as Alzheimer’s and even cancer.
The Nuclear Magnetic Resonance (NMR) method we use can accurately measure the phenolic compounds oleocanthal and oleacein, which are the two most abundant forms of conjugated hydroxytyrosol and tyrosol in most olive oils, as well as oleuropein aglycon and ligstroside aglycon. We post the certificate of analysis at the time it is determined. The range that the overall value of phenolic content (total phenols analyzed) falls (e.g. 1301 mg/kg is within the 1000-1500 mg/kg range) is indicated on the label of each bottle of Olea True. In 2018 the atypical weather conditions in Greece contributed to reduce the phenolic content of olive oils produced. The 2018 Olea True Harvest represents one of the two highest phenolic content olive oils tested. Twice per year we test our oil by a third party to guarantee quality and purity as well as to track the stability of the phenolic compounds and inform our customers.
Below are the recent certificates from the analysis we conducted on our oil.

ABSTRACT: Oleocanthal, a phenolic component of extra-virgin olive oil, has been recently linked to reduced risk of Alzheimer’s disease (AD), a neurodegenerative disease that is characterized by accumulation of β-amyloid (Aβ) and tau proteins in the brain. However, the mechanism by which oleocanthal exerts its neuroprotective effect is still incompletely understood. Here, we provide in vitro and in vivo evidence for the potential of oleocanthal to enhance Aβ clearance from the brain via up-regulation of P-glycoprotein (P-gp) and LDL lipoprotein receptor related protein-1 (LRP1), major Aβ transport proteins, at the blood-brain barrier (BBB). Results from in vitro and in vivo studies demonstrated similar and consistent pattern of oleocanthal in controlling Aβ levels. In cultured mice brain endothelial cells, oleocanthal treatment increased P-gp and LRP1 expression and activity. Brain efflux index (BEI%) studies of (125)I-Aβ(40) showed that administration of oleocanthal extracted from extra-virgin olive oil to C57BL/6 wild-type mice enhanced (125)I-Aβ(40) clearance from the brain and increased the BEI% from 62.0 ± 3.0% for control mice to 79.9 ± 1.6% for oleocanthal treated mice. Increased P-gp and LRP1 expression in the brain microvessels and inhibition studies confirmed the role of up-regulation of these proteins in enhancing (125)I-Aβ(40) clearance after oleocanthal treatment. Furthermore, our results demonstrated significant increase in (125)I-Aβ(40) degradation as a result of the up-regulation of Aβ degrading enzymes following oleocanthal treatment. In conclusion, these findings provide experimental support that potential reduced risk of AD associated with extra-virgin olive oil could be mediated by enhancement of Aβ clearance from the brain.

ABSTRACT: Virgin olive oil (VOO) is credited as being one of many healthful components of the Mediterranean diet. Mediterranean populations experience reduced incidence of chronic inflammatory disease states and VOO is readily consumed as part of an everyday dietary pattern. A phenolic compound contained in VOO, named oleocanthal, shares unique perceptual and anti-inflammatory characteristics with Ibuprofen. Over recent years oleocanthal has become a compound of interest in the search for naturally occurring compounds with pharmacological qualities. Subsequent to its discovery and identification, oleocanthal has been reported to exhibit various modes of action in reducing inflammatory related disease, including joint-degenerative disease, neuro-degenerative disease and specific cancers. Therefore, it is postulated that long term consumption of VOO containing oleocanthal may contribute to the health benefits associated with the Mediterranean dietary pattern. The following paper summarizes the current literature on oleocanthal, in terms of its sensory and pharmacological properties, and also discusses the beneficial, health promoting activities of oleocanthal, in the context of the molecular mechanisms within various models of disease. Keywords: virgin olive oil; ibuprofen; sensory; inflammation; health

ABSTRACT: We explored the anti-cancer capacity of (-)-oleocanthal in human hepatocellular carcinoma (HCC). (-)-Oleocanthal inhibited proliferation and cell cycle progression and induced apoptosis in HCC cells in vitro and suppressed tumor growth in an orthotopic HCC model. (-)-Oleocanthal also inhibited HCC cell migration and invasion in vitro and impeded HCC metastasis in an in vivo lung metastasis model. ( )-Oleocanthal acted by inhibiting epithelial-mesenchymal transition (EMT) through downregulation Twist, which is a direct target of STAT3. (-)-Oleocanthal also reduced STAT3 nuclear translocation and DNA binding activity, ultimately downregulating its downstream effectors, including the cell cycle protein Cyclin D1, the anti-apoptotic proteins Bcl-2 and survivin, and the invasion-related protein MMP 2. Overexpression of constitutively active STAT3 partly reversed the anti cancer effects of (-)-oleocanthal, which inhibited STAT3 activation by decreasing the activities of JAK1 and JAK2 and increasing the activity of SHP-1. These data suggest that (-)-oleocanthal may be a promising candidate for HCC treatment.·

ABSTRACT: Background: Oleacein (dialdehydic form of decarboxymethyl elenolic acid linked to hydroxytyrosol; 3,4-DHPEA-EDA) have been proven to possess antioxidant and anti-inflammatory activity. Purpose: In this study, we examined whether oleacein could increase CD163 and IL-10 receptor expression as well as HO-1 intracellular secretion in human macrophages. Methods: Effect of oleacein (10 and 20 μmol/l) or oleacein together with complexes of haemoglobin (Hb) and haptoglobin 1-1 (Hp11) or haptoglobin 2-2 (Hp22) on expression of IL-10 and CD163 receptor was determined by Flow Cytometry. Expression of CD163mRNA was measured by real-time quantitative RT-PCR. Heme oxygenase 1 (HO-1) intracellular secretion in macrophages was investigated by enzyme-linked immunosorbent assay (ELISA). Results: Oleacein (OC) together with complexes HbHp11 or HbHp22 stimulated the expression of CD163 (30-100-fold), IL-10 (170-300-fold) and HO-1 secretion (60-130-fold) after 5 days of coincubation. The 2-fold (24 h), 4-fold (48 h) increase of CD163 mRNA level and its final (72 h) decrease was also observed. Conclusion: Our results suggested that oleacein enhances anti-inflammatory activity of complexes haemoglobin with haptoglobin 1-1 and 2-2 and could play a potential role in the prevention of inflammatory disease related to atherosclerosis.
