A new narrative review has reported that olive leaf polyphenols, such as Solabia Nutrition's Olecol, can beneficially modulate lipid parameters, oxidative stress, inflammation and vascular function.
The review, published in Food & Function, was conducted by Solabia Nutrition's internal R&D team in collaboration with researchers from Maastricht University.
Why this matters
Proactive blood lipid management is becoming an increasingly hot topic in the nutraceutical industry as cardiovascular health continues to be a leading global concern.
Consumers are seeking natural, safe and clinically validated solutions to help maintain healthy cholesterol levels before pharmaceutical intervention becomes necessary.
This shift is particularly relevant following regulatory changes around Monacolin K from red yeast rice, underscoring the need for effective alternatives.
Olecol is a clinically validated extract derived from freshly pruned Spanish olive leaves of the Manzanilla variety, standardised for key polyphenols, including oleuropein and hydroxytyrosol.
Clinical data demonstrates that Olecol significantly reduces total cholesterol, LDL cholesterol and triglycerides at a daily dose of 250 mg.
Solabia states that, with its strong safety profile and natural origin, Olecol is positioned as a compelling alternative to Monacolin K, supporting blood lipid management without the regulatory and safety concerns associated with red yeast rice.
Review results
The new narrative review summarises evidence about the effects of olive leaf and olive oil polyphenols on blood lipid profiles and cardiovascular risk markers in healthy individuals and those at risk.
It includes studies using standardised olive leaf extracts or olive oil with specific phenolic content, excluding formulations with additional bioactive compounds.
The analysis covers various groups, including healthy individuals, those with cardiovascular risk factors and overweight or hyperlipidaemic subjects, while also incorporating mechanistic insights from preclinical models.
The findings demonstrate that olive-derived polyphenols exert population-dependent benefits in the following:
- In healthy individuals, improvements were primarily observed in oxidative stress and vascular markers
- In individuals with elevated cardiovascular risk, more consistent reductions were seen in LDL cholesterol, total cholesterol, triglycerides and oxidised LDL
- Postmenopausal and mildly hyperlipidaemic individuals showed meaningful improvements, particularly with longer supplementation.
Addressing a growing market need
As scrutiny around Monacolin K intensifies and the demand for natural, safe and effective lipid management solutions rises, Olecol presents a scientifically backed alternative for the nutraceutical market.
Solabia states that the ingredient's clinically proven effectiveness, along with a robust safety profile, makes it a next-generation ingredient for promoting cardiovascular health and supporting healthy ageing.
