Lab One N°1 Quercetin Plus is a dietary supplement with CURSOL™, a unique, patented extract from turmeric, enriched with quercetin and piperine. Vegetable capsules allow you to provide numerous compounds with a wide range of anti-inflammatory properties.

The product was tested for efficacy and safety at Phycher Laboratories in France.

Quercetin – a polyphenol, found widely in plants. This substance is mainly valued for strong anti-inflammatory properties, used to treat some diseases – asthma and diabetes. Quercetin has also antiallergic effects because it inhibits histamine secretion and is an amazing antioxidant. Furthermore, it may support healthy blood vessels by inhibiting the breakdown of hyaluronic acid.

Turmeric root extract CURSOL™ is a source of highly absorbable curcumin. Its health-giving properties have been known and used in Far Eastern medicine for several thousand years. Turmeric is used as a potent antioxidant and agent promoting the function of the cardiovascular, nervous and digestive system.

CURSOL™ is in a powder form and that is why it can be combined easily with other active ingredients – in this case with quercetin and piperine – to enhance anti-inflammatory effects of the formulation. 

Black pepper extract is standardised to contain 95% piperine, a substance which has a positive impact especially on  digestive function. It stimulates the secretion of gastric juices, thereby improving nutrient absorption. It promotes also serotonergic and dopaminergic neurotransmission  and thus affects your mood.

Strong anti-inflammatory properties
Inflammation is the response of the body to harmful external or internal stimuli. They can be pathogenic microorganisms and compounds produced by cells. They include free radicals – highly reactive molecules formed during cellular respiration. Their excessive production may result in chronic inflammation and impaired function of vital organs.

The body can defend against them by producing neutralising enzymes. They include  superoxide dismutase, glutathione peroxidase, glutathione S-transferase and catalase. Curcumin has been shown to be capable of boosting their synthesis and that is why free radicals are eliminated more effectively. In addition, along with quercetin, it regulates the activity of cyclooxygenases and expression of the proinflammatory NF-kB, thereby inhibiting inflammation.

Strong support for the cardiovascular system
Cardiovascular diseases at a certain age affect almost everyone. They are caused especially by an improper diet or too little physical activity combined with a stressful lifestyle. The cardiovascular system is responsible for supplying nutrients to every body cell. Because of that, maintaining its healthy function should be a priority.

Studies show that adding ceratin bioactive compounds to your daily diet may effectively prevent cardiovascular disorders. Curcumin from this supplement may lower blood homocysteine levels. Concentrations of this amino acid are measured to evaluate the risk of atherosclerosis. When they are low, it means that blood vessels are in good condition.

What is more, it is also very crucial that curcumin stabilises levels of prostacyclin (PGI2) which is synthesised by vascular epithelial cells. PGI2 has a relaxant effect on smooth muscles of arteries and therefore lowers blood pressure. Unfortunately, when this substance is released into the blood, it may be inactivated by free radicals, but they are eliminated effectively by curcumin.

Quertecin also inhibits adverse processes in blood vessels and promotes their regeneration. It prevents the breakdown of hyaluronic acid – a substance responsible for arterial elasticity.

Optimisation of nervous system function
The supplement’s ingredients cross effectively the blood-brain barrier and that is why they can act on the central nervous system. Neurons, like other body cells, produce regulatory and structural proteins. Curcumin is one of the substances which enhance the efffectiveness of protein biosynthesis. It may prevent the formation of abnormal proteins and thus protect nerve tissue from gradual degeneration.

What is more, piperine supplementation is helpful especially to individuals with depressive disorders. This substance supports the functioning of the reward system by improving the neurotransmission of serotonin and dopamine. These compounds are called “happiness hormones” because their high levels in the central nervous system are associated with, among others, well-being.

Digestive health
Digestive complaints can be serious. Stomach ache, nausea, diarrhoea and vomiting are caused by digestive disorders and significantly impair the quality of life. Furthermore, they lead to malabsorption of macro- and micronutrients, resulting in dietary deficiencies.

Curcumin improves digestive function in two ways. It stimulates smooth muscles of the bile duct, thereby promoting the secretion of bile and preventing bile stasis. This reduces the risk of gallstones and aids fat digestion. Piperine has in turn slightly different effects. It enhances the secretion enzymes in digestive juices in the stomach and pancreas, consequently facilitating nutrient absorption.

Superior detox
Cells which contain high levels of toxins are not able to divide and repair effectively. Piperine may be helpful in eliminating them. It dilates small capillaries in the skin and liver and thus promotes blood circulation. As a result, harmful metabolites are transported through the bloodstream and may be excreted by the kidneys.

To sum up, Lab One N°1 Quercetin Plus is a top-quality dietary supplement which supports bodily functions on many levels. It contains a blend three ingredients which have strong anti-inflammatory effects and may effectively reduce inflammation in the body and relieve pain. In addition, the supplement helps eliminate toxins and promotes the function of the digestive and nervous system.

Turmeric root extract


What is turmeric root extract?

Turmeric root extract is powdered turmeric in reduced volume in order to achieve as high active curcuminoid concentration as possible.

Turmeric is a spice that gives dishes a characteristic yellow colour. However, apart from its culinary advantages, it is also valued for its great health-promoting potential, which is why it is sometimes called the “Queen of Spices”. The main active substance in turmeric root is curcumin, which has a strong anti-inflammatory effect. In turn, reducing inflammations helps to relieve pain and inhibit the development of cancer.

People who use turmeric extracts can notice an improvement in the parameters marking blood sugar levels and the condition of the cardiovascular system, which is visible in an optimised lipid profile, reduced hypertension, and enhanced blood flow. Curcumin also helps to inhibit DNA molecule damage and reduce oxidative stress. The advantages of curcumin can be experienced by people struggling with the symptoms of depression and anxiety disorders as well.
