Glucofit™ is a banaba supplement extracted naturally from the leaves of Lagestroemia speciosa. This renowned Asian plant helps to regulate glycaemia and maintain a healthy weight. Its content of corosolic acid, the plant’s main active ingredient, is standardised to 18% for maximum efficacy.

Why is it so important to lower glycaemia?

Blood sugar control is a key indication of good health. To understand why, we need to take a moment to look at carbohydrate metabolism.

During digestion, carbohydrates are broken down by digestive enzymes into simple, directly-absorbed sugars called monosaccharides, the chief one being glucose. Glucose moves directly into capillaries in the intestinal villi and then travels to the liver via the hepatic portal vein, producing an increase in glycaemia. At this point, the glucose can either:

  • remain in the blood to maintain normal glycaemia;
  • be used directly by the liver for its metabolic activity;
  • reach the body’s cells to serve as instant fuel;
  • be stored in the liver and/or skeletal muscle as glycogen, a form of energy storage.

The last two options are governed by insulin, a hormone secreted by the pancreas: its fundamental role is to lower blood sugar levels by, in particular, promoting the absorption of glucose by cells.

If glycaemia is too high, however, these ‘buffer’ mechanisms become saturated. The insulin then converts the excess glucose into fat deposits which will be stored in adipose tissue, potentially leading to weight gain.

What’s more, in overweight individuals, cell receptors tend to become indifferent to insulin, preventing the uptake of glucose, so creating a vicious circle: this is referred to as insulin resistance. (1) It’s the starting point for various metabolic disorders, precipitating the onset of cardiovascular problems in particular.

It should also be noted that the reaction that takes place between glucose and proteins (glycation) has the effect of accelerating cellular ageing (2).

Banaba leaves, Asia’s ‘green insulin’

Indigenous to tropical Asia, banaba (Lagestroemia speciosa) is part of the Lythraceae family. Populating the forests of the Philippines, Malaysia, Indonesia, Thailand and Taiwan, it bears magnificent flowers ranging in colour from bright pink to purple, making it a very popular ornamental tree.

However, it’s the banaba leaves which are of particular interest to the scientific community. Having featured for centuries in the traditional south-east Asian pharmacopoeia, they have gone on to be used in the form of an extract or a tea for overweight people or those with blood sugar problems (3). As a result, they are now referred to as ‘green insulin’ by those working in the field of nutraceuticals.

Banaba’s effects on blood sugar levels have made it the subject of several ongoing studies which are focusing on the role played by its corosolic acid.

What health benefits are offered by the banaba supplement Glucofit™?

Glucofit™ offers two major benefits:

  • Normalisation of blood sugar levels. A clinical study involving 100 subjects with type 2 pre-diabetes or diabetes looked at the effects of one month’s daily supplementation with a banaba extract standardised to 18% corosolic acid. The researchers observed a 10% reduction in fasting and post-prandial blood sugar levels. Similar results were seen in genetically diabetic mice (3-5).
  • Aid to weight loss. In a comparative clinical study the preliminary results of which have just been published, subjects supplemented with the new Glucofit™ for 60 days lost more than 4.5kg including 70% in fat mass, while those given the old GlucosolTM ‘only’ lost 3kg. These results appear to confirm the dose-dependent efficacy of corosolic acid for controlling weight (5).

Olive leaves and three olives

Olive Leaf Extract is a natural formula in vegetarian capsules produced from olive leaves, designed to control lipidemia. It is supported by three clinical studies which have confirmed its ability to lower LDL-cholesterol and triglyceride levels, increase HDL-cholesterol and fight lipid peroxidation, now available to buy at Supersmart.

What compounds are in Olive Leaf Extract?

The beneficial effects of the olive tree are attributed to its exceptionally high content in phenolic compounds, molecules known for their antioxidant potency. In the olive tree, these compounds play a part in defending the tree from insects, infection, multiple microbial attacks and UV radiation (1-2), but they are also biologically active when ingested by humans. They are known to reduce the risk of a number of diseases by combatting free radicals and improving enzymatic balance.

Oleuropein is the most abundant phenolic compound in the olive tree (3) (accounting for around 25% of the extract). It is oleuropein that gives extra virgin olive oil its characteristic bitterness, but there are many other such compounds found in Olive Leaf Extract: apigenin, caffeic acid, catechins, coumaric acid, diosmetin, ferulic acid, gallic acid, hesperidin, hydroxytyrosol, luteolin, oleoside, quercetin, rutin, tyrosol, vanillin, verbascoside…

As the oleuropein in olive leaves has been scientifically shown to be responsible for the plant’s benefits, Olive Leaf Extract is formulated to contain an optimum amount of this compound.

What are the mechanisms of action of Olive Leaf Extract?

Olive Leaf Extract’s effects on the cardiovascular system.

Olive leaves have been used in phytotherapy since antiquity apparently for their antilipidemic, antiseptic and antiviral properties.

Scientific research has since confirmed these applications and identified new properties: antimicrobial (4-5), antiviral (6), antifungal (7), gastro-protective (8), blood glucose-lowering (9), blood pressure-lowering (10), antioxidant (11-12), antiatherogenic (13), hypolipidemic (14), anti-inflammatory (15), neuro-protective (16), vasodilatory (17) and anti-ageing (18).

There are three precise mechanisms of action which are responsible for the majority of Olive Leaf Extract’s effects on the cardiovascular system:

1) Cholesterol-lowering action

The olive tree’s polyphenols, particularly oleuropein, act on cholesterol excretion (19). They promote the elimination of excess cholesterol via the bile ducts, duodenum and finally faeces.

2) Antioxidant action

The antioxidant potential of oleuropein is exceptional. When elderly institutionalised individuals followed a diet enriched with an extract of oleuropein and its derivatives for six weeks, their antioxidant capacity was shown to improve (20). It is a natural solution to combatting oxidative stress and inhibiting LDL oxidation (21).

3) Action on sugar absorption

By binding to sucrase and maltase, two digestive enzymes, oleuropein limits sugar absorption and thus reduces spikes in blood glucose. It also does this by slowing down the activity of the sugar transporter, GLUT2.

Five good reasons to choose Olive Leaf Extract to maintain healthy blood vessels

1) The antioxidant content of olives depends to a large extent on variety, maturity and preservation. Therefore, if you live a long way away from the Mediterranean region where they’re grown, you can’t really rely on eating olives all year round to boost your cardiovascular health. With its exceptional and stable content in olive tree polyphenols, Olive Leaf Extract provides a solution to this problem, offering populations the world over the opportunity to fully benefit from the advantages of a Mediterranean diet.

2) Eating a Mediterranean diet is associated with a lower risk of all-cause mortality (25). Scientific studies have in large part attributed these protective effects to the role played by the olive tree (26).

3) The bioavailability of oleuropein in humans is very high – between 55% and 60% (27). Maximal plasma concentration occurs two hours after oral administration. Studies have also shown that oleuropein crosses the blood-brain barrier easily.

4) The Mediterranean diet was recognized by UNESCO in 2010 as an Intangible Cultural Heritage of Humanity.

5) Cardiovascular disease is the leading cause of mortality across the world, claiming more than 17 million lives each year.
