Olive Leaf Extract


Throughout the Mediterranean region, the Olive tree has traditionally been revered for its many qualities including the leaves. Olive Leaf is often recommended to help support healthy immune function.

Traditionally used to:

  • Support immunity
  • Assist in general health and well-being
  • Protect against viral, bacterial and parasitic invasion
  • Supports cardiovascular health
  • Fights free radical damage as a strong antioxidant and helps protect LDL particles from oxidative damage.
  • Supports healthy blood sugar levels already within the normal range.
  • Supports the body to control blood pressure levels already within the normal range.
  • Supports a healthy immune, circulatory, urinary and digestive systems.

The research suggests that this may be a “true anti-viral” compound because it appears to selectively block an entire virus-specific system in the infected host. It thus appears to offer healing effects not addressed by pharmaceutical antibiotics.

Nature’s Sunshine Advantage:
This amazing product delivers one of the highest levels of oleuropein available anywhere. To ensure maximum results, Olive Leaf Extract is specially prepared by a patented process to concentrate its desired natural benefits. And considering its high level of effective ingredients, standardized to 12 percent oleuropein, it is competitively priced.

Olive (Olea europa) Leaf Extract 400 mg
12% oleuropein (standardized) 48 mg

Recommended Use:
Take 1 – 3 capsules daily with a meal.

Researchers credit a number of unique properties possessed by the Olive Leaf compound for it’s broad killing power: Olive Leaf has been found to contain a phytochemical called oleuropein which in-vitro and in-vivo animal studies suggest has anti-bacterial and anti-viral properties.

Scientific research has found Olive Leaf has the following properties in killing viral infections:

  1. An ability to interfere with critical amino acid production essential for virus cell survival.
  2. An ability to contain viral infection and/or spread by inactivating viruses or by preventing virus shedding, budding or assembly at the cell membrane.
  3. The ability to directly penetrate infected cells and stop viral replication.
  4. In the case of retroviruses, it is able to neutralize the production of reverse transcriptase and protease. These enzymes are essential for a retrovirus, such as HIV, to alter the RNA of a healthy cell.
  5. It can stimulate phagocytosis, an immune system response in which cells ingest harmful microorganisms and foreign matter.

In a series of experiments, oleuropein was found to inactivate bacteria by apparently dissolving the outer lining of microbes.

The Olive Leaf extract exhibits antiviral activity against viral haemorrhagic septicaemia rhabdovirus (VHSV). … Furthermore, LExt drastically decreased VHSV titers and viral protein accumulation (virucidal effect) in a dose dependent manner when added to cell monolayers 36 h post-infection.

Researchers at Upjohn found Olive Leaf extract effective in test tube experiments against the following viruses: herpes, vaccinia, pseudorabies, Newcastle, Coxsacloe A 21, encepthlomyocarditis, polio 1, 2, and 3, vesicular stomititus, sindbis, reovirus, Moloney Murine leukemia, Rauscher Murine leukemia, Moloney sarcoma, and many influenza and parainfluenza types.

At the University of Milan Pharmacological Sciences, researchers found that oleuropein inhibited oxidation of low-density lipoproteins, the so-called “bad cholesterol” involved in heart and arterial disease. This revelation, if confirmed by further research, suggests that oleuropein may contain antioxidant properties similar to other phytochemical compounds.

Medical researcher Morton Walker, D.P.M., writing about Olive Leaf extract in the July 1996 issue of the Townsend Letter for Doctors and Patients, comments that the intake of flavonoids “is correlated with a lower incidence of cardiovascular disease indicated that the daily intake of olive oil and/or Olive Leaf extract containing phenols will likely bring on a similar result.”

At the present time, the cardiovascular research community is excited about such actions. Studies have shown that some phytochemicals can reduce the harmful oxidation of cholesterol as well as slow down the accelerated clumping of blood platelets that can lead to dangerous clots.

At Spain’s University of Granada, pharmacologists determined that Olive Leaf extract causes relaxation of arterial walls in laboratory animals. Such results suggest a possible benefit for hypertension, an effect first mentioned by researchers more than 30 years ago.

In Tunis, researchers found that aqueous extract of olive leaves reduced hypertension, blood sugar, and the level of uric acid in rodents. This finding again indicates potential in the treatment of hypertension, as well as diabetes and heart disease. An elevated uric acid level is a risk factor for heart disease.

They found it effective against these bacteria and parasitic protozoans: lactobacillus plantarum W50, brevis 50, pediococcus cerevisiae 39, leuconostoc mesenteroides 42, staphylococcus aureus, bacillus subtilis, enterobacteraerogenes NRRL B-199, E. cloacae NRRL B-414, E. coli, salmonella tyhimurium, pseudomonas fluorescens, P. solanacearum, P. lachrymans, erwinia carotovora, E. tracheiphila, xanthomonas vesicatoria, corynesbacterium Michiganese, plasmodium falciparum, virax and malariae.
