NAC and Turmeric/Curcumin: what the published research says

PubMed indexes 4 records that name NAC and Turmeric/Curcumin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to NAC and Turmeric/Curcumin. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

4 studies naming NAC and Turmeric/Curcumin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Curcumin and N-Acetylcysteine Nanocarriers Alone or Combined with Deferoxamine Target the Mitochondria and Protect against Neurotoxicity and Oxidative Stress in a Co-Culture Model of Parkinson's Disease.

Antioxidants (Basel, Switzerland) · 2023 · PMID 36670992

“These results indicate that the P68 + DQA nanocarriers were successful at enhancing the protective effects of curcumin, NAC and/or DFO by increasing the brain penetrance and targeted delivery of the associated bioactives to the mitochondria in this model. This study thus emphasises the potential effectiveness of this nanocarrier strategy in fully utilising the therapeutic benefit of these antioxidants and lays the foundation for further studies in more advanced models of PD.”

Mursaleen et al. · From the abstract

Names both NAC and Turmeric/Curcumin in its title.

Protective Effects of Curcumin and N-Acetyl Cysteine Against Noise-Induced Sensorineural Hearing Loss: An Experimental Study.

Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India · 2022 · PMID 36032833

“There was a statistically significant difference in the third measurements in both groups 2 and 3, possibly due to curcumin and NAC treatment. This study showed that curcumin and NAC may be effective against noise-induced hearing loss.”

İskender Emekli et al. · From the abstract

Names both NAC and Turmeric/Curcumin in its title.

N-acetyl cysteine mitigates curcumin-mediated telomerase inhibition through rescuing of Sp1 reduction in A549 cells.

Mutation research · 2010 · PMID 20363232

Human subjects

“Further, reporter assay and DNA affinity precipitation assay confirmed the influence of curcumin on Sp1 in hTERT regulation. This is the first study to demonstrate that curcumin induces ROS production resulting in Sp1 binding activity inhibition and hTERT downregulation.”

Hsin et al. · From the abstract

Names both NAC and Turmeric/Curcumin in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers NAC, Turmeric/Curcumin, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
