Turmacin® (Water-Soluble Turmeric Polysaccharides — Natural Remedies)

Curcuma longa
Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

Turmacin® is a water-soluble turmeric (Curcuma longa) extract from Natural Remedies, standardized not for curcumin but for turmerosaccharides, the polysaccharide compounds of turmeric. These water-soluble compounds are studied for supporting joint comfort and mobility through a different mechanism than curcumin.

Studied Dose 500 mg twice daily (1,000 mg/day) in the knee-osteoarthritis trial; 500 mg or 1,000 mg once daily in the healthy-adult exercise trial.
Active Compound Water-soluble turmeric extract standardized to turmerosaccharides (turmeric polysaccharides), distinct from the fat-soluble curcuminoids.

Benefits

Joint comfort

Turmerosaccharides are studied for supporting joint comfort and easing joint discomfort, offering a water-soluble, curcumin-free turmeric option.

Supported by Trial 1

Mobility and flexibility

In a double-blind trial of healthy adults, Turmacin improved knee range of motion after strenuous exercise compared with placebo.

Supported by Trial 1

Anti-inflammatory support

The turmeric polysaccharides act on inflammatory pathways involved in joint discomfort.

Supported by Trial 1

Mechanism of action

1

Turmerosaccharide activity

The water-soluble turmeric polysaccharides modulate inflammatory mediators in joint tissue, a mechanism separate from curcumin's.

2

Cartilage-supportive signaling

The extract is studied for protecting joint tissue from inflammatory breakdown.

Clinical trials

1
Human RCT: Turmacin (NR-INF-02) in painful knee osteoarthritis
PubMed

Randomized, single-blind, placebo-controlled trial in 120 adults with primary painful knee osteoarthritis. NR-INF-02 (Turmacin) 500 mg twice daily for 42 days lowered pain and improved joint function versus placebo. (Madhu et al. 2013, Inflammopharmacology). Small industry-linked trial.

120 adults with primary painful knee osteoarthritis.

NR-INF-02 (Turmacin) 500 mg twice daily lowered VAS pain and WOMAC function scores and reduced rescue-medication use versus placebo over 42 days. The trial was single-blind and used the maker's own extract, so the result needs independent confirmation.
