Do Turmeric Supplements Work? Here’s What the Science Says

By Duane Mellor | June twentieth, 2023

Turmeric has been utilized by people for greater than 4,000 years. In addition to cooking and cosmetics, it’s been a staple of the standard medication follow of Ayurveda, used to deal with quite a lot of circumstances. Even at this time, turmeric stays a well-liked well being complement. There are many articles and social media posts claiming the advantages of this spice for the whole lot from mind operate to lowering ache and irritation. However whereas a few of these claims are linked to proof, most of this analysis is in cells and animals, making the precise results on people much less clear. Right here’s what we all know.

What are curcuminoids?

Whereas turmeric is reported to include over 100 completely different compounds, most of its reported well being advantages are linked to particular compounds referred to as curcuminoids (probably the most ample being curcumin). Curcuminoids are phenolic compounds, that are molecules that crops typically make as pigments or to discourage animals consuming them. That is what provides turmeric its distinctive color, however it could possibly additionally change how cells operate.

Lots of the potential well being results of turmeric have been linked to those phenolic compounds which, within the lab, have been proven to have an antioxidant impact.

Antioxidants are substances which stop or sluggish injury attributable to free radicals – a dangerous sort of molecule that may trigger irritation, and has additionally been linked to coronary heart illness and most cancers.

However whereas turmeric does certainly act as an anti-inflammatory, most of the well being advantages attributable to this impact have solely been confirmed within the lab (utilizing cells) or in animals.

For instance, one examine fed overweight mice one gram of curcumin per kilogram of physique weight. After 12 weeks, they discovered that the mice given curcumin had comparable enhancements in mind operate and decrease ranges of irritation of their liver because the mice who had been on a weight reduction food regimen.

So whereas this will likely have translated to more healthy mice, it’s unclear whether or not the identical can be true in people. To not point out that had this examine been performed in people, a median 70kg particular person would have wanted to devour over 2 kilograms of turmeric each day in the course of the trial – which might be unimaginable.

Since no comparable research have but been performed on people, we nonetheless don’t perceive whether or not turmeric reduces irritation in an identical means.

Turmeric’s impact on ache

But regardless of the shortage of analysis displaying advantages in people, turmeric (and curcumin) are broadly marketed as anti-inflammatory dietary supplements for a variety of circumstances – together with joint ache and arthritis. In keeping with the outcomes of 1 evaluation, it does appear that in human trials turmeric dietary supplements could have a modest profit on ache in comparison with a placebo – and in some instances as as useful as non-steroidal anti-inflammatory medication.

However the research included on this evaluation seem like of variable high quality. Many had been performed utilizing a really small inhabitants (ten individuals or fewer) and had a large variation within the quantity of turmeric contributors got. This implies it’s laborious to make a transparent suggestion that turmeric is efficient for ache.

Turmeric has additionally been recommended to have anti-cancer properties resulting from its anti-oxidant impact. Within the lab, curcumin has been proven to reverse DNA modifications in cells which trigger breast most cancers. Nevertheless it’s much less clear whether or not turmeric reduces the chance of most cancers or helps therapy in people. Some analysis has proven that utilizing a turmeric gargle might scale back the unwanted effects of radiotherapy in individuals with head and neck cancers, nevertheless.

It could additionally assist individuals with a uncommon genetic situation referred to as acquainted adenomatous polyposis, with one medical trial discovering that consuming 120mg curcumin (about the identical as a teaspoon of turmeric) was linked with fewer cancer-causing polyps for individuals with this situation – which generally is a signal of the early phases of most cancers.

With irritation being linked to many cognitive well being circumstances equivalent to dementia, some analysis has sought to know whether or not turmeric can profit mind operate. Up to now, it’s unclear whether or not turmeric has any impact.

The trials which have been performed in people have usually been very small, with an absence of consistency in examine design, dosage and the way they measured cognitive results. Once more, this makes it troublesome to see whether or not turmeric actually does have an impact, or whether or not any cognitive enhancements are resulting from different elements.

Does turmeric actually work?

A significant problem in getting turmeric to work in our our bodies is getting it from our intestine into our bloodstream. Curcumin is kind of a big compound – and as such might be laborious for the physique to soak up into the bloodstream as a result of it isn’t very soluble in water.

However different analysis means that turmeric works by appearing on the micro organism in our guts. Though extra knowledge is required on whether or not that is true in people, it might recommend that turmeric doesn’t must be absorbed into the bloodstream as a way to present well being advantages as a result of it’s already absorbed by our intestine.

One other problem is the quantity of turmeric wanted to see advantages. In lots of research solely the curcumin extract is used – which makes up solely about 3 to five p.c of turmeric powder itself. With many research giving larger than 1 gram of curcumin per kilogram for a mouse or rat, the equal quantity for these results to be seen in a human can be troublesome to attain – even in complement kind.

Turmeric is a superb spice, giving a pleasing earthy flavour and vibrant pure yellow color to meals. Nevertheless it’s removed from clear how its reported advantages translate to human well being. So, get pleasure from turmeric as a spice and a color in meals, however don’t depend on it to ship main well being advantages or to deal with or treatment illness.
