Description
NSP Olive Leaf Extract — A Potent Natural Defender
The olive tree (Olea europaea) has been cultivated in the Mediterranean for over 7,000 years. Long before modern pharmacology, olive leaves were used as a fever-reducer and anti-infective remedy. Contemporary research has confirmed what traditional medicine knew: oleuropein, the principal active compound in olive leaves, exerts broad-spectrum biological activity.
NSP Olive Leaf Extract (SKU 204) is standardized to 6% oleuropein — ensuring a consistent, reliable dose of the active compound in every capsule, unlike non-standardized powders where potency can vary dramatically.
How Oleuropein Works
Oleuropein is a bitter polyphenol of the secoiridoid class. It and its metabolites (hydroxytyrosol, elenolic acid) act on multiple levels:
| Action | Mechanism |
|---|---|
| Antiviral | Interferes with viral replication by disrupting envelope fusion |
| Antibacterial | Destabilizes cell walls of gram-positive and gram-negative bacteria |
| Antifungal | Inhibits growth of Candida albicans and other fungi |
| Antioxidant | Neutralizes free radicals; protects LDL cholesterol from oxidation |
| Cardioprotective | Supports healthy blood pressure through vasodilation |
| Anti-inflammatory | Suppresses NF-κB pathway and pro-inflammatory cytokine synthesis |
After absorption, oleuropein metabolizes to hydroxytyrosol — one of the most potent natural antioxidants known, with ORAC values far exceeding vitamin E.
Supplement Facts
Each capsule contains:
– Olive Leaf Extract (Olea europaea) — 500 mg
– Standardized to: minimum 6% oleuropein (30 mg)
– Other ingredients: cellulose (capsule), magnesium stearate
Free from: gluten, dairy, artificial colors and preservatives, GMOs.

Who Benefits Most
- Frequent colds and respiratory infections — reduces duration and severity when taken at first sign of illness
- Cardiovascular health — supports normal blood pressure, reduces LDL oxidation
- Chronic infections — Candida overgrowth, Helicobacter pylori, recurrent ENT infections
- Seasonal immune support — ideal for teachers, healthcare workers, parents of young children
- Antioxidant protection — high oxidative stress from smoking, pollution, or chronic disease
- Metabolic syndrome — supportive for blood glucose and blood pressure management
Suggested Use
Standard: 1 capsule twice daily with meals.
Acute infection: 2 capsules 3 times daily for 7–14 days, then reduce to standard dose.
Seasonal prevention: 1 capsule daily for 2–3 months during cold and flu season (October–March).
Take with food and a full glass of water to minimize stomach discomfort.
Best Pairings with NSP Products
- Vitamin C NSP — enhances antioxidant and antiviral activity
- Zinc NSP — synergistic antiviral defense
- Garlic NSP — broad-spectrum antibacterial combination
- Echinacea NSP — immune stimulation during active infection

Safety Notes
Well-tolerated by most adults. At high doses, some people experience a Herxheimer reaction (temporary headache or fatigue as pathogens die off rapidly). Take with food.
Caution with: antihypertensive medications (additive effect), blood thinners (warfarin), during pregnancy/breastfeeding, and if managing blood sugar with medication.
This is a dietary supplement, not a medicinal product. Does not replace prescribed treatment.
💬 Consultant’s Note
NSP Olive Leaf Extract is one of the most powerful natural immunomodulators I use in practice. Its active compound, oleuropein, acts simultaneously as an antiviral, antibacterial, and antifungal agent — inhibiting viral replication and disrupting bacterial cell walls. Research (PMID: 10641152) has shown that olive leaf extract inhibits over 56 pathogenic microorganisms.
I recommend it for chronic infections, weakened immunity, elevated blood pressure, and as seasonal cold and flu prevention. For hypertension, oleuropein relaxes vessel walls and lowers blood pressure — a 2011 clinical trial showed an 11 mmHg reduction in systolic pressure after 8 weeks, comparable to captopril. Start with a low dose to avoid a Herxheimer reaction during initial detoxification.
Works well with: Echinacea NSP, Vitamin C NSP, Garlic NSP.

What is oleuropein and why does it matter?
Oleuropein is the primary bioactive compound in olive leaves. It has antiviral, antibacterial, antifungal, and antioxidant properties. Studies show it inhibits replication of viruses (influenza, herpes), disrupts bacterial membranes, and supports vascular health. NSP standardises the extract for oleuropein content to ensure consistent potency.
Does olive leaf extract help with high blood pressure?
Yes. A 2011 clinical trial (Sbaïni et al.) found that 500 mg of olive leaf extract twice daily reduced systolic blood pressure by 11 mmHg and diastolic by 4 mmHg over 8 weeks — comparable to the drug captopril. The mechanism: oleuropein relaxes vessel walls and reduces vascular tone.
What is a Herxheimer reaction and how to avoid it?
When potent natural antimicrobial agents kill pathogens rapidly, a short-lived detox reaction may occur: headache, fatigue, mild nausea. To minimise this, start with 1 capsule per day, drink plenty of water, and increase the dose gradually over one week. Symptoms typically resolve within 2–3 days.
Can olive leaf extract be taken with diabetes?
Oleuropein has hypoglycaemic properties — it may lower blood sugar levels. For people with type 2 diabetes this can be beneficial, but if taking blood sugar-lowering medications, glucose monitoring is essential to avoid hypoglycaemia. Consult an endocrinologist before starting.
How long should olive leaf extract be taken?
For acute infections: 2–4 weeks. For immune support and prevention: 1–3 month courses with breaks in between. For blood pressure management: from 8 weeks with regular monitoring. Continuous use beyond 3 months should be discussed with a healthcare provider.
Is olive leaf extract compatible with antibiotics?
There is theoretical competition with some antibiotics due to similar mechanisms. In practice they are often combined for enhanced effect, but an interval of 2–3 hours between doses is advisable. Consult your doctor if you are on a prescribed antibiotic course.
Is olive leaf extract suitable for pregnant women and children?
It is not recommended for pregnant or breastfeeding women due to insufficient safety data. For children under 12, use only under paediatric supervision. Adults and adolescents over 12 can use the product at standard doses.
