Overview

What Is NOW Foods Turmeric Curcumin and Why Does It Matter?

Nature's Sunshine Turmeric Curcumin (Formerly CurcuminBP) is a concentrated Turmeric formula designed to promote a healthy inflammatory response and deliver broad-spectrum antioxidant defense. If you've been searching for a now foods Turmeric Curcumin option that prioritizes both potency and absorption, this product stands out because each serving is equivalent to 32,000 mg of whole root Turmeric — delivering high levels of both Turmeric root and the antioxidant-rich Turmeric extract that provides the curcuminoids behind Turmeric's centuries-old reputation.

The formula provides 1,100 mg of Turmeric extract with 1,000 mg of curcuminoids per two-capsule serving. Curcuminoids are the primary active compounds obtained from the rhizomes of Curcuma longa L., the yellow curry spice that has been used safely in Indian Ayurvedic medicine for centuries. To address Curcumin's well-documented challenge of poor oral bioavailability, this product is enhanced with Black pepper extract, which research suggests may dramatically improve how much Curcumin your body actually absorbs.

Nature's Sunshine Turmeric Curcumin is clinically studied and formulated to deliver superior absorption and effectiveness. It supports joint, skin, brain, and gut health as well as immune system function — making it a versatile addition to daily wellness routines. The product is non-GMO and comes in a 60-count VegCap format.

Science & Mechanisms

How Turmeric Curcumin Works in the Body

Curcumin, the dominant curcuminoid in Turmeric, has been extensively investigated for its capacity to modulate multiple signaling pathways involved in inflammation and oxidative stress. Research suggests it exerts its core anti-inflammatory effects mainly by inhibiting the activation of the nuclear factor-κB (NF-κB) signaling pathway, as well as regulating the MAPK and JAK/STAT cascades. Through these pathways, Curcumin may help reduce the production of inflammatory cytokines such as TNF-α, IL-1β, and IL-6.

Curcumin also suppresses the activity of COX-2 and LOX enzymes, which are responsible for producing prostaglandins and leukotrienes — inflammatory mediators that can contribute to joint discomfort and stiffness. On the antioxidant side, studies suggest Curcumin activates the Keap1-Nrf2/ARE transcriptional pathway, which upregulates the body's own cytoprotective enzymes, including superoxide dismutase (SOD), catalase, and glutathione.

The biggest challenge with Curcumin supplementation has always been bioavailability. Numerous factors — low water solubility, poor intestinal permeability, instability at alkaline pH, and rapid metabolism — contribute to Curcumin's limited oral absorption. That's why this formula includes Black pepper extract containing piperine, which inhibits the enzymes (particularly UGT and CYP3A4) that rapidly break down Curcumin. One landmark study found that piperine co-administration increased Curcumin bioavailability by 2,000% in human subjects.

What's inside

Key ingredients

tumeric extract — 1,100 mg
This standardized extract of Curcuma longa L. delivers a concentrated source of curcuminoids, the polyphenolic compounds responsible for Turmeric's vibrant yellow color and its extensive body of research. Turmeric has been used in Ayurvedic medicine for roughly 6,000 years, traditionally employed for digestive disorders, arthritis, skin conditions, and inflammatory ailments. Modern research has built substantially on this traditional foundation. Multiple systematic reviews and meta-analyses of randomized controlled trials suggest Turmeric extract may support joint comfort and function in osteoarthritis, with some studies finding effects comparable to NSAIDs. A 2022 meta-analysis of 29 RCTs (2,396 participants across five arthritis types) confirmed consistent improvements in pain and inflammatory markers. Research also suggests Turmeric extract may promote healthy inflammatory response by targeting NF-κB, COX-2, and 5-LOX pathways — key mediators of chronic inflammation — though a 2019 meta-analysis of 19 RCTs found inconsistent reductions in circulating inflammatory markers, reflecting ongoing scientific debate. On the antioxidant front, clinical trials have demonstrated measurable improvements in total antioxidant capacity (TAC), SOD, and glutathione while lowering lipid peroxidation markers such as malondialdehyde (MDA), primarily through activation of the Nrf2-Keap1 signaling pathway. Studies also suggest Turmeric extract may support cartilage health — a landmark RCT of 367 knee OA patients found Turmeric extract equivalent to ibuprofen 1,200 mg/day for knee pain relief, and ESCEO guidelines recognize curcuminoids as an OA nutraceutical. Additional research areas include flexibility and mobility (a 2025 network meta-analysis of 39 RCTs ranked Curcumin/Turmeric among the supplements with significant functional benefits), rheumatoid arthritis (where Curcumin inhibits COX-2, NF-κB, and multiple pro-inflammatory cytokines), and gout support (a small 2025 RCT found 1,000 mg Curcumin/day reduced uric acid levels and gout flares, though a separate study in asymptomatic hyperuricemia was not superior to placebo). It is worth noting that Curcumin's poor oral bioavailability remains a central limitation in translating laboratory findings to clinical outcomes, which is why this formula pairs Turmeric extract with Black pepper extract.
curcuminoids — 1,000 mg
Curcuminoids are the family of polyphenolic pigments within Turmeric responsible for its biological activity. Food-grade Curcumin consists of approximately 77% Curcumin (diferuloylmethane), 17% demethoxycurcumin, and 3% bisdemethoxycurcumin. Curcumin, the dominant curcuminoid, was first isolated in 1815 and has since become one of the most extensively studied natural compounds. Studies suggest curcuminoids may support antioxidant defense by significantly reducing malondialdehyde (MDA) and raising enzymatic antioxidants such as SOD, catalase, and glutathione peroxidase, with the primary mechanism involving activation of the Nrf2-Keap1 signaling axis. For joint health, a meta-analysis of 29 RCTs (2,396 participants across five arthritis types) confirmed significant pain and inflammation reductions with Curcumin supplementation. A 2014 head-to-head RCT found 1,500 mg/day Curcumin equivalent to ibuprofen 1,200 mg/day in knee OA, with better GI tolerability. For chronic inflammation specifically, multiple meta-analyses of RCTs demonstrate significant reductions in key biomarkers — CRP, IL-6, and TNF-α — following Curcumin supplementation, working primarily through inhibition of NF-κB and downstream pro-inflammatory cytokine cascades. A 2025 systematic review of 21 studies involving 1,705 knee OA patients found that CRP and TNF-alpha levels were significantly lower in Curcumin groups compared to placebo. Studies also suggest curcuminoids may support flexibility and mobility, with a 2025 network meta-analysis of 39 RCTs (4,599 knee OA patients) confirming benefits in joint function outcomes. For rheumatoid arthritis, a 2025 network meta-analysis of 18 RCTs found Curcumin superior to placebo in reducing swollen and tender joint counts and inflammatory markers. Research into cartilage health shows Curcumin inhibits inflammatory cytokines that drive cartilage degradation, and the Arthritis Foundation explicitly cites Curcumin for bursitis support. Evidence quality across these areas is generally rated low to moderate due to small sample sizes, formulation heterogeneity, and bioavailability limitations.
Black pepper extract
Black pepper extract (from Piper nigrum L.) is included in this formula primarily as a bioavailability enhancer. Its major bioactive compound, piperine, inhibits drug-metabolizing enzymes — particularly CYP3A4 and UDP-glucuronosyltransferase (UGT) — and P-glycoprotein efflux transporters that would otherwise rapidly break down and eliminate Curcumin before it can be absorbed. The bioavailability-enhancing effect of piperine is its most robustly documented property in human clinical studies: one study found that when 20 mg of piperine was combined with Curcumin, blood concentrations of Curcumin increased by 2,000% within 45 minutes of co-administration. Beyond absorption enhancement, research suggests piperine may contribute its own anti-inflammatory activity. Studies show piperine inhibits COX-2 gene expression and enzyme activity, and multiple human RCTs using Curcumin-piperine combinations have documented significant reductions in CRP, hs-CRP, and IL-6 in metabolic syndrome and other inflammatory conditions. In vitro studies using human rheumatoid arthritis synoviocytes found piperine inhibited IL-6, MMP13, COX-2, and PGE2 in a dose-dependent manner, while animal arthritis models showed significant reductions in inflammation and joint inflammatory area. Piperine also demonstrates antioxidant properties — human RCTs using Curcumin-piperine combinations show improvements in superoxide dismutase, total antioxidant capacity, and malondialdehyde in metabolic syndrome and chronic disease populations. Black pepper is FDA-recognized as GRAS (generally regarded as safe) and has been used in Ayurvedic medicine for thousands of years, where it forms part of the classical trikatu preparation. Important note: because piperine inhibits CYP3A4 and other drug-metabolizing enzymes, individuals taking prescription medications should consult a healthcare professional before use.
dicalcium phosphate
Dicalcium phosphate serves as a common excipient in supplement manufacturing, providing a source of both Calcium and phosphorus. Calcium is the most abundant mineral in the human body, with more than 99% stored in bone as hydroxyapatite. Beyond its structural role, Calcium is widely involved in cell signaling, muscle contraction, neuronal transmission, and enzyme regulation. As a supplement ingredient, dicalcium phosphate helps maintain capsule integrity and consistent dosing. The body absorbs approximately 30% of Calcium from supplemental sources under normal conditions, with absorption facilitated by adequate vitamin D status.
