Berberine Supplement

Berberine 500mg is a superior quality supplement obtained from common barberry. It contains an exceptionally high level of berberine, a phytonutrient known for its remarkable effects on cardiovascular health and one which has been used for thousands of years in Ayurvedic medicine.

What is berberine?

Berberine is a substance produced by certain plants such as common barberry (Berberis vulgaris). It is an alkaloid – a “natural, organic compound with a complex molecular structure (heterocyclic), which has marked physiological properties, even at low doses” according to the hypothesis put forward by Winterstein and Trier. It’s a fascinating group of natural products with significant therapeutic potential.

In vitro, this alkaloid can exert antioxidant, anti-inflammatory, hypoglycaemic, hypotensive and hypolipidemic effects (1 – 2), its most important property being that of acting as a calcium channel blocker.

Which plants contain berberine? Apart from common barberry, berberine is also found in Mexican prickly poppy, goldenseal, Oregon grape, yellowroot and Berberis aristata, a shrub that grows in the Indian Himalayas.

From where is berberine sourced? How is it produced?

Plants from the Berberis genus grow in all the world’s semi-tropical regions. That’s why berberine is such an integral part of the major systems of traditional medicine, such as Ayurvedic and Chinese medicine.

Our berberine supplement is obtained from Berberis vulgaris (common barberry) which grows predominantly in Iran, the world’s largest producer with 11,000 hectares of cultivation. Various parts of the plant are suitable for therapeutic use, namely the bark, the root and the stem, though it’s the dried barberries which are most commonly-used (3 – 4). It has been judged completely safe for human use by the American FDA (5).

Barberry contains other alkaloids such as oxyacanthine, berbamine, bervulcine and columbamine, but it’s berberine which attracts most interest among the scientific community. That’s why we’ve chosen to enrich our natural extract with berberine (guaranteed to contain 97% active principles).

What are berberine’s mechanisms of action?

Berberine has been widely studied for its properties and physiological effects. The plant from which it is extracted has been traditionally used for thousands of years: reference to the use of Berberis vulgaris for ‘purifying the blood’ has been found on clay tablets in the personal library of the Assyrian Emperor Ashurbanipal, dating back to 650 BC. It was also used in Ayurvedic medicine to treat infections, aid wound-healing and ‘open the mind’.

With an estimated intestinal absorption of between 0.4 and 1%, there are questions surrounding its bioavailability when taken orally, which is considered to be low (7). However, in vivo studies show that distribution of orally-ingested berberine in tissues is much greater than its concentration in blood. It is rapidly transported to the kidneys, muscles, heart, pancreas, liver and fat, where it is metabolised and converted into berberrubine, thalifendine and jatrorrhizine, its main active metabolites (8).

Scientists are currently investigating its mechanisms of action: hundreds of studies evaluating its benefits for cardiovascular health are published each year.

Pharmacokinetic interactions have already been observed when it is co-administered with cyclosporin A (used for treating auto-immune diseases) and metformin (used for reducing insulin-resistance in type 2 diabetes) (9).

Questions from internet-users

Why is Supersmart’s berberine more expensive than other supplements?

The Berberis vulgaris extract offered by Supersmart is standardized to 97% berberine, the highest percentage available to buy on the market. It contains nothing else apart from natural acacia fibre and rice flour, completely safe, natural-source excipients. It represents a considerable technical achievement as producing berberine in a capsule is not easy.

What can I take alongside berberine?

There are several supplements available to buy at Supersmart which may be of interest for helping to prevent high blood sugar and improve cardiovascular health.

• For example, the compounds in the formulation Carbo Defense™ can help control carbohydrate metabolism, primarily by reducing the absorption of sugars in the small intestine.
• DHA (docosahexaenoic acid), sold in supplement form as Super DHA, helps maintain normal triglyceride levels (10).
• PectaSol® (a natural concentrate of lemon pectins) helps reduce post-prandial increases in blood sugar (when taken with meals at a dose of at least 10g) (11).
• Beta 1.3/1.6 Glucan, a natural substance obtained from yeast cell walls, helps maintain optimal cholesterol levels (12).

And if you like taking phytonutrients, you also have a number of options:

• Apple Polyphenols, a concentrate of apple polyphenols.
• A broccoli extract standardized in sulforaphane glucosinolate.
• Olive Leaf Extract, a ‘Mediterranean’ formulation with a triple action against cholesterol and triglycerides.
• Double Pomegranate, a pomegranate-based supplement with high antioxidant potency.

What dose of berberine should I take?

The therapeutic dose used in the majority of clinical studies is between 200mg and 500mg, two to three times a day. Supersmart’s berberine comes in 500mg vegetarian capsules, to be taken just before meals, at these same intervals.

If you find swallowing capsules hard, there’s nothing to prevent you from breaking open the capsules and diluting the contents in a glass of water, fruit juice or yogurt. Berberine is actually converted by oral flora into dihydroberberine, which may be absorbed better in the gut (13).
