AllOlive® (Full-Spectrum Olive Extract — Natac)

Olea europaea
Evidence Level
Limited
0 Clinical Trials
3 Documented Benefits
2/5 Evidence Score

AllOlive® is a full-spectrum olive (Olea europaea) extract from Natac that concentrates the main compounds of the olive plant, oleuropein, pentacyclic triterpenes, hydroxytyrosol, and tocopherols, in a single standardized ingredient. The aim is to deliver the broad benefits of olive polyphenols rather than a single isolated compound.

Studied Dose Commonly around 250 to 500 mg of the extract per day.
Active Compound Full-spectrum olive extract standardized to oleuropein (about 20%), pentacyclic triterpenes (about 13%), hydroxytyrosol, and tocopherols.

Benefits

Cardiovascular support

Olive polyphenols such as oleuropein and hydroxytyrosol are well studied for supporting blood-vessel function and healthy blood pressure; AllOlive concentrates these compounds, though dedicated trials of this specific extract are limited.

Antioxidant defense

Hydroxytyrosol and oleuropein are powerful antioxidants that help protect cells and blood vessels from oxidative stress.

Full-spectrum olive profile

By keeping olive's natural mix of polyphenols and triterpenes, the extract aims to deliver broader support than single-compound olive products.

Mechanism of action

1

Olive polyphenol action

Oleuropein and hydroxytyrosol support nitric-oxide-mediated blood-vessel relaxation and antioxidant defense, the basis of olive's cardiovascular reputation.

2

Triterpene support

Olive pentacyclic triterpenes add anti-inflammatory and protective activity to the extract.

Clinical trials

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — adverse effects are uncommon at normal doses.
Mild digestive upset is occasionally reported.
Discontinue if any unusual reaction occurs.

Important Drug interactions

Blood pressure medication — olive polyphenols may have an additive effect; monitor.
Generally compatible with a healthy diet.
Tell your doctor if you take cardiovascular medication.

Relevant to the olive-polyphenol component but not evidence for the AllOlive extract specifically.
