Olive Leaf Extract, Meta-inflammation, Anxiety, and Excess Weight
Condition(s) studied
Investigational drug(s) / intervention(s)
Olive Leaf Extract (OLE): Daily dose of 750mg OLE consumed with water after breakfast without any modification of their dietary patterns for 90 days.
Placebo: 100mg microcrystalline cellulose
Study summary
Excess Weight is accompanied by a process that produces a low-grade inflammation state, called meta-inflammation. Anxiety is also associated with inflammation. Inflammation is closely related to oxidative stress. Both processes help perpetuate each other. Olive Leaf Extract (OLE) is known for having anti-inflammatory and antioxidant effects; by this means, its anxiolytic effect has been proved in animal models. The purpose of this investigation is to evaluate the anti-inflammatory and anxiolytic effects associated with the supplementation of OLE at a daily dose of 750mg (20% oleuropein) for 3 months.
Eligibility
Primary outcome measure(s)
- Change in TNF-α concentration — Baseline, day 0, pre-supplementation, on an empty stomach, and day 90 (on an empty stomach, 24 hours after the last supplement/placebo intake).
Measured by ELISA assay (Enzyme-Linked ImmunoSorbent Assay) according to the manufacturer's recommendations. The kit is a Human TNF-α ELISA kit; measured in pg/mL. - Change in IL-6 concentration — Baseline, day 0, pre-supplementation, on an empty stomach, and day 90 (on an empty stomach, 24 hours after the last supplement/placebo intake).
Measured by ELISA assay (Enzyme-Linked ImmunoSorbent Assay) according to the manufacturer's recommendations. The kit is a Human IL-6 ELISA kit; measured in pg/mL - Change in leptine concentration — Baseline, day 0, pre-supplementation, on an empty stomach, and day 90 (on an empty stomach, 24 hours after the last supplement/placebo intake).
Measured by ELISA assay (Enzyme-Linked ImmunoSorbent Assay) according to the manufacturer's recommendations. The kit is a Human leptin ELISA kit; measured in pg/mL - Change in cortisol concentration — Baseline, day 0, pre-supplementation, on an empty stomach, and day 90 (on an empty stomach, 24 hours after the last supplement/placebo intake).
Measured by ELISA assay (Enzyme-Linked ImmunoSorbent Assay) according to the manufacturer's recommendations. The kit is a Human cortisol ELISA kit; measured in pg/mL. - Change in Anxiety symptomatology scored by Hamilton Anxiety Scale (HAS) — From baseline, day 0, pre-supplementation, up to day 60, during supplementation. It will be applied bimonthly, twice in total.
Measured in accordance to the next score: 0-5, absence of anxiety; 6-14, mild anxiety; ≥15, moderate/severe anxiety, on an alternately, monthly, basis; in the morning in a peaceful controlled environment. - Change in Anxiety symptomatology scored by Beck Anxiety Index (BAI) — Its first application will be on day 30, during supplementation, up to day 90 (24 hours after the last supplement/placebo intake). It will be applied bimonthly, twice in total.
Measured in accordance to the next score: 0-5, absence of anxiety; 6-15, mild anxiety; 16-30, moderate anxiety; 31-63 severe anxiety, on an alternately, monthly, basis; in the morning in a peaceful controlled environment.
