Sometimes a name tells a story. Here’s one that came from Sabinsa’s R&D scientists’ obsession with turmeric extracts:

Curcuminoids are yellow-colored active principles present in turmeric (Curcuma longa) and have proven health benefits. However, recent studies reveal that curcumin undergoes metabolic conversion by the intestinal microbiota, specifically curcumin in the human intestine is converted into tetrahydrocurcumin (Reductive metabolite) by E. coli. The process is found to be the same with other curcuminoids. Studies observed that, after oral ingestion of curcuminoids, various tetrahydrocurcuminoids are detected in the blood serum, supporting the role of curcuminoid metabolites in the health benefits of curcuminoids.

Because of Sabinsa’s three decades of experience in curcumin research and product development, we know it inside and out. Our understanding the importance of tetrahydrocurcuminoids led to the development of a process to convert the yellow curcuminoids into white tetrahydrocurcuminoids. Sabinsa being Sabinsa, we wanted to share it with the world, which is how the product Curcumin C3 Reduct® was born. “Reduct” in the brand name comes from “reductase,” which is an enzyme that catalyzes a reduction reaction. This reduced reaction is everything required to harness the full health benefits of in turmeric. This name definitely tells the story.

Researchers from Stanford University, International Centre for Diarrhoeal Disease Research, Bangladesh and Johns Hopkins University were investigating the causes of high levels of lead (Pb) in bloodstream of the Bangladeshi population, a source of serious health concerns. They analyzed various possible source of Pb intake such as food containers, food components (turmeric) and other material viz., clay soil or ash.

By measuring the Pb radioisotope level in the blood samples and possible source for lead contamination they come to conclusion that turmeric is the source of lead, which is leading to increased Pb levels in the bloodstream of majority of the Bangladeshi population. They identified the source of high levels of Pb in turmeric as being from a colorant, Lead chromate (PbCrO4). Lead chromate is a yellow colored pigment which some suppliers use to enhance the color of turmeric.

Also the researchers publicized the study to warn consumers and regulatory agencies around the globe to be alert for lead toxicity from turmeric products.


During 1980s, due to the massive flood, turmeric crops are becomes wet and dull in colour. Demand for yellow coloured Turmeric let the processors adulterated with synthetic yellow pigment (Lead chromate) to acheive desirable color.

  • The researchers analyzed several potential sources from which the lead contamination is possible
  • The selected sample size of the study is relatively small, making it difficult to generalize the measured source Pb concentrations and the reported consumption behaviors to population
  • The study says the adulteration is happening in the samples distributed in Bangladesh but not in product exported from Bangladesh
  • The samples collected were produced in local small scale manufacturers (unbranded) and sold by the local vendors.
  • No commercial curcumin extract has been found to contain Pb contamination. The researchers are alerting consumers to be careful in choosing turmeric products but are not suggesting that every turmeric product is contaminated or that turmeric itself contain high levels of lead

Ginger has been used through the ages for both its enjoyable culinary properties and its health benefits. The world’s oldest healthcare systems, including Ayurveda, emphasize strong digestive function, and ginger has been one of the primary herbs used for that purpose for thousands of years. Today, modern science has not only confirmed those benefits, but expanded upon what ancient doctors taught.

Ginger’s wonderful flavor serves a purpose - its stimulation of the taste buds influences the release of digestive enzymes to break down the food to extract nourishment. Throughout history, ginger has been used to improve gut-related conditions such as dyspepsia, flatulence, bloating, nausea, intestinal cramping, vomiting, and other stomach complaints we’d rather not experience.1,2,3

It's not just an old wives’ tale recommending ginger for morning sickness; research confirms that ginger calms nausea and vomiting during pregnancy and is useful in counteracting the same side effect of chemotherapy.4

Ginger also supports healthy liver function. Research shows benefits in managing non-alcoholic fatty liver disease, a rapidly growing health concern, among other benefits.5

One of ginger’s properties is that it is warming, which is why it is incorporated into so many dishes traditionally served in the cold weather months. A cup of ginger tea is almost miraculous in its ability to counteract the chills brought on by winter weather.

Today, ginger is not only used for food seasoning by many consumers, it’s also taken in dietary supplements, so they get its benefits every day.
