Recent clinical research in children with cystic fibrosis reported that nanocurcumin reduced inflammation throughout the body, reduced gut inflammation, increased anti-inflammatory cells, increased healthy weight gain, improved quality of life and reduced Pseudomonas colonies. There is not currently a cure for cystic fibrosis, and nanocurcumin should not replace medical treatment. But human research in people with CF has shown encouraging results, particularly when a highly bioavailable form is used.
Quick answer
- There is only one study of nanocurcumin supplementation in people with cystic fibrosis. It is from 2023, in children, and published in the medical journal Food Science and Nutrition.
- It reported less inflammation in the body (CRP) and in the gut (faecal calprotectin), more of the anti-inflammatory signal IL-10, 16% more healthy weight gain, better quality of life and 52% fewer Pseudomonas colonies.
- The only other trial, using standard curcumin against the CF medication ivacaftor, found no clinical effect, and almost no curcumin in the blood. Absorption is the whole story.
- Lab studies suggest nanocurcumin reduces the growth of Pseudomonas aeruginosa and that curcumin may reduce airway inflammation in CF.

At a glance: what does human research show?
There is only one study of nanocurcumin supplementation in people with cystic fibrosis (not lab studies or studies in animals). The study is from 2023 and published in the medical journal Food Science and Nutrition [1].
Nanocurcumin supplementation in cystic fibrosis:
- Reduced inflammation throughout the body (CRP)
- Reduced inflammation in the gut (faecal calprotectin level)
- Increased anti-inflammatory interleukin-10 (IL-10)
- Increased healthy weight gain by 16%
- Improved quality of life
- Reduced Pseudomonas colonies by 52%
This 2023 clinical research study in people with cystic fibrosis concluded: "Nano-curcumin seems to be an effective nutritional supplement in patients with CF."
Curcumin supplementation in people with cystic fibrosis
As of writing, there are two studies examining turmeric or curcumin supplementation in people with cystic fibrosis: one using standard curcumin and the other using highly bioavailable nanocurcumin.
The first study used standard curcumin and compared this to the common CF medication ivacaftor [2]. The drug had significant benefits; curcumin did not. The researchers wrote: "We observed no clear clinical effect of curcumin. Blood concentrations of the food supplements were low."
The second sentence is very important. Curcumin had no benefit in people with CF, but there was almost no curcumin in the blood after taking curcumin supplements. So taking turmeric or even standard curcumin supplements is unlikely to help cystic fibrosis.
The problem with standard curcumin
One of the biggest challenges with conventional curcumin supplements is that very little is absorbed after it is swallowed. This poor absorption means that although curcumin has impressive biological activity in laboratory studies, much less reaches the bloodstream and tissues in humans where it can have benefit. This may help explain why clinical studies using standard curcumin have often produced disappointing results.
Nanocurcumin: a better form of curcumin
Nanocurcumin is designed to overcome one of the biggest limitations of conventional curcumin by dramatically improving its absorption. Because the curcumin particles are much smaller, more of the active compound can reach the bloodstream and the tissues where it is needed and can have benefit. This improved bioavailability has led researchers to investigate whether nanocurcumin may produce better clinical outcomes than standard curcumin.
Nanocurcumin has also been studied in other immune and inflammation conditions, including multiple sclerosis and migraine.
What the lab studies suggest
A 2020 lab study reported that nanocurcumin reduced the growth of Pseudomonas aeruginosa [3]. Pseudomonas aeruginosa is a bacterium that can cause difficult-to-treat infections, especially in people with cystic fibrosis.
A 2025 lab study reported that curcumin might reduce airway inflammation and damage in CF [4].
Where nanocurcumin fits in
Gold Standard Curcumin provides 80 mg of nanocurcumin per capsule together with vitamin D3. Nanocurcumin should not replace medical treatment for cystic fibrosis. If you are thinking about it, bring this article, and its references, to your next appointment with your CF team.
