Vespro Monolaurin & 20% Olive Leaf Extract

Immune Support


Antibiotics not only indiscriminately kill unwanted micro-organisms, but they also destroy the friendly bacteria and viruses that the body needs to function efficiently. This can lead to major health disruptions, especially immune system function. Antibiotic resistance, a result of the abuse of prescription drugs, is one of the major problems facing the medical community today. An alternative to the use of antibiotics is to find new uses for a class of safe chemicals that are non-toxic to humans while providing broad-spectrum, anti-viral protection.

What is Monolaurin and How Does it Work?

This natural compound is a fatty acid and corresponding glycerol esters. Lauric acid was first discovered as the main anti-viral and anti-bacterial substance in human breast milk. Monolaurin is the glycerol ester of lauric acid and is more biologically active than lauric acid. In studies performed at the Respiratory Virology Branch, Center for Disease Control, Atlanta, Georgia, (the CDC), Monolaurin was tested for virucidal activity against 14 human RNA and DNA-enveloped viruses in cell culture. These included influenza, RSV, Rubeola, Newcastle�s, Corona virus (avian infectious, bronchitis virus), Herpes Simplex types 1 &2, Epstein - Barr virus (EBV) and cytomegalovirus. Monolaurin removed over 99.9% or all measurable infectivity of the 14 viruses by disintegrating the virus envelope. In addition to its antiviral effects, monolaurin is non-toxic and has also been shown to have antibacterial activity against Staphylococcus aureus, Streptococcus agalactiae, Groups A, F &G Streptococci, Chlamydia, H.Pylori and against yeast and fungi as well, including Candida and ringworm. Monolaurin has no effect on naked viruses such as Polio, Coxsackie, Encephalitis or Pox viruses.

What is Olive Leaf Extract and How Does it Work?

Olive Leaf is known for its anti-bacterial and anti-fungal activity. It has been shown to enhance the immune system and is a potent antioxidant. Our Monolaurin and Olive Leaf Extract product contains 205mg of a 20% Olive Leaf Extract.

How Safe are These Supplements?

Not only is Monolaurin included on the GRAS (Generally Recognized As Safe) list, but because of its origin, it may be safer than many other food supplements that are designed to boost the immune system. Olive Leaf has been traditionally used by herbalist to combat viruses and bacterial infections.

Suggested Use:

Monolaurin is not a nutritional supplement you need to take on a daily basis (although many people take it regularly for prevention) but only when needed. It is always best to see your physician when you have a fever or swollen glands, but if you sense the early warning signs of influenza or a cold, Monolaurin and Olive Leaf Extract may begin to combat the virus.


Each capsule of Monolaurin and Olive Leaf Extract contains 615mg of Monolaurin and 205mg of Olive Leaf Extract. As a food supplement, take 2 capsules per day.


Warning: Seek the advice of your health care professional before using if you are pregnant, nursing or have any medical conditions. If symptoms persist or worsen, consult a health care professional.

Additional information


Monolaurin is an anti-microbial agent that protects the immune system from a range of infectious agents. Monolaurin is a glyceride ester derivative of lauric acid, a fatty acid found naturally in breast milk and certain vegetable oils. This fatty acid has been used as a germicidal agent for centuries. Lauric acid was originally discovered when microbiologists studied human breast milk to determine the antiviral substances which protected infants from microbial infections. It has been shown to protect newborns, whose immune systems are underdeveloped, from Respiratory Syncytial Virus (RSV) and other respiratory tract viruses (1,2). Monolaurin was found to have even greater viral activity than lauric acid. As a dietary supplement, Monolaurin has shown exciting results as an anti-viral and anti-bacterial agent.

Monolaurin works by destroying lipid-coated viruses such as herpes, cytomegalovirus, influenza, and various pathogenic bacteria and protozoa.

Monolaurin works by binding to the lipid-protein envelope of the virus, thereby preventing it from attaching and entering host cells, making infection and replication impossible. Other studies show that Monolaurin disintegrates the viral envelope, killing the virus.

In studies performed at the Respiratory Virology Branch, Centers for Disease Control, Atlanta, Georgia, Monolaurin was found effective against 14 human RNA and DNA enveloped viruses in cell culture (3). These included influenza, RSV, Rubeola, Newcastle's, Coronavirus, Herpes Simplex types 1 & 2, Epstein-Barr Virus (EBV) and cytomegalovirus. (Monolaurin has no effect on naked viruses, such as polio, encephalitis virus, coxsachie, or pox viruses.) Monolaurin removed all measurable infectivity by disintegrating the virus envelope. In addition to its antiviral effects, monolaurin has also been shown to have antibacterial activity against Staphylococcus aureus, Streptococcus agalactiae, Groups A, F & G streptococci, Chlamydia, H. pylori, and against yeast and fungi as well, including Candida and ringworm.

Monolaurin serves as a valuable nutritional adjunct for people who feel that they are coming down with a cold or flu. Many physicians have developed their own clinical protocols in their cold and flu prevention program and recommend taking several capsules of Monolaurin on an empty stomach.

Monolaurin is not the type of nutritional supplement you have to take on a daily basis (although many people take it regularly for prevention purposes), but only when the need arises. If you have a fever or swollen lymph glands, it is always best to see a physician, but if you sense the early warning signs of the flu, like sniffles, sore skin and perhaps a scratchy throat, Monolaurin may offer the first line of defense.

Antibiotics kill unwanted micro-organisms, but they also kill many friendly micro-organisms. Monolaurin, on the other hand, does not appear to have an adverse effect on desirable digestive bacteria, but rather only on unwanted microorganisms. In addition Monolaurin can reduce the resistance of germs to antibiotics.

Frequent antibiotic use can lead to major disruptions in health and especially immune system function. Antibiotic resistance, resulting from the over-use of prescription drugs, is one of the biggest problems facing the medical community today. Resistance is cumulative (and comes in part from antibiotics in our food supply). That's why it's important to consider starting with nutritional agents, such as Monolaurin, first. Uncomplicated flu, while unpleasant, is not life threatening and doesn't necessitate drug therapy. Nutritional physiologic agents, such as Monolaurin, may be a good first choice.

Not only is Monolaurin included on the GRAS (Generally Recognized As Safe) list, but it may, by virtue of its source of origin, be safer than many other food supplements that are designed to boost the immune system.

One of the safest substances known to man is breast milk. This is where the monoglyceride of lauric acid (Monolaurin) is found. When an infant is born, it is totally dependent on food factors in the mother's milk for immune protection. In analyzing the composition of human breast milk, medical researchers found lauric acid monoglycerides in high concentrations, which is what led them to study Monolaurin as an anti-viral agent (4,5). Monolaurin is also found in coconut oil, butter, and heavy cream; only recently has it been isolated and purified. It is highly unusual in pharmacology to find chemicals that are toxic to lower forms of life (bacteria, fungi, and viruses) but non-toxic to man.

For those with a sensitive stomach, Monolaurin can be taken with food. The dose can be tapered off as symptoms decrease. Of course, you should always seek the advice of a physician if you have fever, pain or if symptoms persist.

Young children can also take Monolaurin at a reduced dose. If you are giving Monolaurin to children (or adults) who have difficulty swallowing capsules, you can break them open and sprinkle the Monolaurin into something such as applesauce or yogurt.


Sometimes the herpes virus can be activated by Monolaurin and then killed, resulting in a Herxheimer-like reaction.


Similar protocols have been used with the Epstein-Barr virus (closely resembling the herpes virus), which may be responsible for Chronic Fatigue and even MS (16, 17).

Use of olive oil and olive leaves dates back as far as recorded history. The key active component of Olive leaf is oleuropein. Oleuropein is converted into elenoic acid in the body which may prevent viruses and bacteria from replicating. Olive leaf has been used for many years in the nutritional supplement industry to help ward off infections. Olive leaf has been shown to be effective against the following microorganisms: E. coli, Pseudomonas aeruginosa, S. aureus, K. pneumonia, Trichophyton mentagrophytes, Microsporum canis, T. rubrum and Candida albicans. Its use in Candida, along with Oregano Oil should be considered a first line of treatment. Hypoglycemic activities of olive leaf are attributed to two mechanisms: potentiation of glucose-induced insulin release and increased peripheral uptake of glucose. Olive Leaf may help to lower blood sugar levels as a result, especially in adult onset diabetes as well as hyperglycemia.

Olive leaf has also been shown to lower cholesterol, and a study shows the whole leaf extract is more effective than the standardized oleuropein extract. It may also lower blood pressure and has some historical use as such.

The following information taken from the website is worth noting:

Nevertheless, research and interest in olive leaf extracts has moved forward, primarily in Europe. Among the most recent findings are these:

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

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.

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.
