Curcumin (from Turmeric) has been used for thousands of years for its antibacterial, anti-viral, anti-inflammatory & anti-fungal properties. Due to its inherent poor absorbency, high doses of ordinary Curcumin 95% have been needed to achieve the dramatic effects shown in worldwide studies. Now, CurcuminX4000™ resolves this with its unique high utilization formulation.


Each capsule of CurcuminX4000™ contains 200mg of highly effective Curcumin Phytosome, which in a recent study showed an increase in utilization up to 45X compared to ordinary Curcumin 95%.

A Breakthrough in Curcumin Absorption*

Whether taken as a supplement or from food, regular curcumin is generally poorly absorbed into the bloodstream. Working with Indena S.p.A., the worldwide experts in botanical extract technology, we have found the answer to better curcumin absorption – phytosome technology.

*Two studies have shown CurcuminX4000™ to be significantly better absorbed than a standardized curcumin extract.


For People Who Just Play Too Hard

We all have occasional aches and pains from over-exertion. We play too hard, work too hard, and we pay for it with stiff joints and sore muscles. CurcuminX4000™ can help reduce the occasional stiffness and soreness we all experience.*

The body’s normal inflammatory response is a natural process and a contributor to many reactions that go on in your body. This response happens automatically and is not something you can control. The primary objective of the body’s normal inflammatory response is to isolate and eradicate irritants and then repair surrounding tissue.


What is “Normal Inflammatory Response?”

The term “normal inflammatory response” may not mean much to you, but its physical impact on your body is vitally important. It can arise from trauma, infection, or other influences, and is a normal process that encourages healing. From the slightest seemingly harmless bump on your arm to a major health concern, the body’s normal inflammatory response is always at work to keep you as healthy as possible or to restore your health as best as it can. Of course, a lot of this depends on individual health.

The body’s normal inflammatory response is the protective response of the body’s tissues to irritation or injury. Sometimes this response can be prolonged due to a deficiency of essential fatty acids or other nutrients. In such cases, supplementation with beneficial fatty acids or other nutrients is often suggested. Sometimes there are other reasons for a prolonged inflammatory response and physical therapy or dietary changes may be helpful. For centuries, people have used natural chemicals found in plants (phytochemicals) to enhance the body’s normal inflammatory response to injury or wear and tear. For example, the bark of the willow tree was used to relieve pain and discomfort more than 2,000 years ago by the Greeks and Romans and evolved into the aspirin we use today.



Curcumin – Supports the Body’s Normal Inflammatory Response*

curcumin 1

Turmeric, a well-known traditional herb, contains curcumin, a potent antioxidant that offers numerous health benefits.* Most of these benefits come from curcumin’s strong antioxidant activity and its ability to support the body’s normal inflammatory response.* Curcumin interacts with numerous biochemicals in the body to promote the body’s normal inflammatory response and help keep this response functioning as it should.*

Emerging research suggests curcumin’s antioxidant activity and support of the body’s normal inflammatory response, as well as its potential to support already normal cholesterol levels, has a significant role to play in contributing to cardiovascular health, liver function, and joint health.*

Absorption You’ve Been Aching For

The potential health benefits of curcumin are the subject of numerous ongoing clinical studies and have been featured in print media and television news programs. However, what makes curcumin so beneficial to the human body – its molecular structure – also makes it difficult to be absorbed into the bloodstream. If the curcumin isn’t absorbed, it can’t get to the body’s cells that need it. To address this issue, Thorne Research has teamed up with Indena S.p.A., the worldwide experts in botanical extract technology, to bring you CurcuminX4000™, a well-absorbed curcumin extract.*

Superior Absorption*

Phytosomes are plant extracts bound to phosphatidylcholine (fos-fa-tidal-ko-leen), which is an essential component of human cells. Our bodies make phosphatidylcholine, but we can also get it from food and supplements. When taken orally, phosphatidylcholine is very well-absorbed.* To improve absorption, scientists at Indena found a way to attach curcumin to phosphatidylcholine – the result is CurcuminX4000™! When you take CurcuminX4000™, your body readily absorbs the phosphatidylcholine and the curcumin attached to it, resulting in more curcumin reaching the cells that can benefit from it.*


Superior Bioavailability*

A 2007 study published in the journal Cancer Chemotherapy and Pharmacology demonstrated CurcuminX4000™’s superior bioavailability compared to a standardized curcumin extract. This animal study noted a significantly greater amount of curcumin in the blood and tissue after dosing with CurcuminX4000™.

A human study compared blood levels of curcumin after dosing with 4 grams of a standardized curcuminoid extract to 450 mg CurcuminX4000™ curcuminoids (bound to phosphatidylcholine), and found similar blood levels of curcumin.

Bio-available curcumin

bioCurcuminX4000™ is a patented complex of Curcumin, a dietary phenolic, with soy phosphatidyl choline(1). The two compounds form a non-covalent adduct in a 1:2 weight ratio, and two parts of microcrystalline cellulose are then added to improve formulation, with an overall contents of Curcumin of 20%.

Turmeric has a long history of medicinal use, especially to treat inflammation(2), and many of its traditional uses have been mechanistically validated in cellular systems as well as in animal models of disease. Indeed, with almost 3000 pre-clinical investigations, Curcumin is one of the best investigated products of the whole biomedical literature(2). These studies have demonstrated that Curcumin acts as a master switch of inflammation by acting at level of enzymes (COXs and LOs) and transcription factors (NF-kB) level, as well as at their genomic expression(3). However, little clinical evidence of efficacy has so far been reported, and most of the beneficial effects of Curcumin are suggested by epidemiological studies, supported by studies in animal models, extrapolated from studies in vitro, but not validated clinically(2). This paradoxical situation is mainly due to the poor drug-ability of Curcumin with a dismally low oral absorption, characterized by plasma concentrations that are barely overcome 50 ng/mL after administration of dosages as high as 12 g/die(4).

Curcumin, just like most dietary phenolics, is sparingly soluble both in water and in oily solvents, but shows polar groups (two phenolic hydroxyl and one enolic hydroxyl) that can interact via hydrogen bondings and polar interactions with complementary group, like the polar heads of phospholipids. Thus, phosphatidylcholine has a highly polarized head, with the negative charge of a phosphate group and the positive charge of the choline ammonium group, and can complex a variety of poorly soluble phenolics, including Curcumin(1). Phenolics shows a high affinity for biological membranes, and, once complexed with phospholipids, are embedded into a lipidic matrix that by capitalizing on the rapid exchange of phospholipids between biological membranes and the extracellular fluids, can lead to an increased cellular capitation.

A 2007 study published in the journal Cancer Chemotherapy and Pharmacology(5) demonstrated CurcuminX4000’s superior bioavailability compared to a standardized Curcumin extract in rats. CurcuminX4000™ improved plasma Cmax and AUC of curcuminoids by 20-fold and levels of Curcumin in the liver increased by much more then a 20 folds. This improved in bioavailability did not translate to increased toxicity levels.

In a recent registry study(6), 50 patients with osteoarthritis (OA) divided into two groups were treated with CurcuminX4000™:

Group A was managed using the “best available treatment as defined by patient’s GP and by specialist.
Group B was managed using the best treatment as above in association with CurcuminX4000™ administered as a food supplement at a dosage of 200mg curcumin/die, a dosage much lower than those used in previous and ongoing clinical studies, that can reach 8g/die.

Both objective and subjective end-points were evaluated: mobility was studied by walking performance (treadmill), and the inflammatory status was assessed by measurements of C-reactive protein (CRP) plasma concentration. OA signs/symptoms were evaluated by the WOMAC scores.

After three months of treatment, the global WOMAC score (used to evaluate OA signs/symptoms) decreased by 58% (p < 0.05), walking distance in the treadmill test was prolonged from 76 m to 332 m (p < 0.05), and CRP levels decreased from 168 ± 18 to 11.3 ±. 4.1 mg/L in the subpopulation with high CRP. In comparison, the control group experienced only a modest improvement in these parameters (2% in the WOMAC score, from 82 m to 129 m in the treadmill test, and from 175 ± 12.3 to 112 ± 22.2 mg/L in the CRP plasma concentration), while the treatment costs (use of anti-inflammatory drugs, treatment and hospitalization) were reduced significantly in the treatment group.
