Discover how NatureWise Turmeric Curcumin Complex with 1,000 mg curcuminoids and Black pepper extract supports joints, inflammation, and antioxidant defense.

Overview

What Is NatureWise Turmeric Curcumin Complex?

The NatureWise Turmeric Curcumin Complex from Nature's Sunshine harnesses a potent Turmeric extract to promote a healthy inflammatory response throughout the body. One serving delivers the equivalent of 32,000 mg of whole root Turmeric and provides 1,000 mg of curcuminoids — the primary active compounds obtained from the rhizomes of Curcuma longa L., the yellow curry spice used safely for centuries in Indian Ayurvedic medicine.

What sets this formula apart is its emphasis on delivering higher levels of antioxidant-rich Turmeric extract rather than relying solely on Turmeric root powder. The formula is further enhanced with Black pepper extract, which research has shown may increase the absorption of Curcumin by as much as 2,000%. The result is a clinically studied combination designed for superior absorption and effectiveness.

This product supports joint, skin, brain, and gut health, as well as immune system function. It comes in a 60-count bottle of VegCaps and carries a non-GMO designation.

How It Works

Understanding Turmeric, Curcumin, and Bioavailability

Curcumin is the dominant curcuminoid in Turmeric and the compound responsible for its vibrant yellow color. As a naturally occurring polyphenol, Curcumin has been extensively investigated for its capacity to modulate multiple signaling pathways — including NF-κB, MAPK, and JAK/STAT cascades — which play pivotal roles in regulating inflammatory responses, cellular proliferation, and antioxidant defense.

Studies suggest that Curcumin supports a healthy inflammatory response by inhibiting the NF-κB signaling pathway and reducing the production of inflammatory cytokines such as TNF-α and IL-1β. It also suppresses COX-2 and LOX enzymes responsible for producing inflammatory mediators like prostaglandins and leukotrienes. On the antioxidant side, Curcumin activates the Keap1-Nrf2/ARE transcriptional pathway, which upregulates the body's own cytoprotective enzymes.

The most significant challenge with Curcumin is its naturally poor oral bioavailability — due to low water solubility, poor intestinal permeability, and rapid metabolism. That's why this formula includes Black pepper extract containing piperine, which has been shown in human pharmacokinetic studies to increase Curcumin bioavailability by approximately 2,000% at 45 minutes after co-administration. Piperine works by inhibiting glucuronidation enzymes (UGT) and P-glycoprotein, slowing the rate at which Curcumin is metabolized and eliminated.

What's inside

Key Ingredients

tumeric extract — 1,100 mg

Turmeric (Curcuma longa L.) is a rhizomatous herbaceous perennial belonging to the ginger family Zingiberaceae, with a history of medicinal use spanning nearly 6,000 years. In Ayurveda, Turmeric has traditionally been used as a potent remedy for digestive disorders, arthritis, skin diseases, and inflammatory conditions. The extract in this formula is standardized to deliver high levels of curcuminoids, the primary bioactive polyphenols. Research suggests Curcumin supports antioxidant defense by raising total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase, and glutathione in multiple human RCTs, while lowering the lipid-peroxidation marker malondialdehyde (MDA). Its primary antioxidant mechanism involves activation of the Keap1-Nrf2/ARE transcriptional pathway. For joint health and arthritis, multiple RCTs and systematic reviews demonstrate consistent improvements in knee OA pain, stiffness, and function compared to placebo. A 2022 meta-analysis of 29 RCTs involving 2,396 participants across five types of arthritis confirmed significant pain and inflammation reductions. A landmark comparative RCT (n=367 knee OA patients) found Turmeric extract equivalent to ibuprofen for knee pain relief, and ESCEO guidelines recognize curcuminoids as an OA nutraceutical. For flexibility and mobility, a 2025 network meta-analysis of 39 RCTs (4,599 knee OA patients) ranked Curcumin among supplements with significant functional benefits, and a 2021 review confirmed significant improvement in pain relief and physical function. Regarding chronic inflammation, Curcumin targets key pro-inflammatory pathways — NF-κB, JAK/STAT, and MAPK — and downregulates cytokines such as TNF-α, IL-6, and IL-1β. A 2023 GRADE-assessed meta-analysis found positive aggregate effects on CRP, IL-6, and TNF-α, though a 2019 meta-analysis found no statistically significant reduction, reflecting ongoing scientific debate. Poor oral bioavailability remains the primary factor limiting clinical translation. Research also suggests Curcumin may support cartilage health by inhibiting NF-κB, COX-2, 5-LOX, and pro-inflammatory cytokines that drive cartilage degradation. For rheumatoid arthritis, Curcumin inhibits COX-2, 5-LOX, NF-κB, and multiple pro-inflammatory cytokines implicated in RA, with multiple RCTs and meta-analyses supporting its use for reducing RA pain, joint stiffness, and inflammatory markers. Additionally, Curcumin is explicitly cited by the Arthritis Foundation for bursitis, and a 2016 systematic review found 1,000 mg/day Curcumin reduced OA pain comparably to NSAIDs. For gout, a small 2025 RCT (n=48) found Curcumin reduced uric acid levels, gout flares, and pain, though results from a separate RCT in asymptomatic hyperuricemia were not superior to placebo, indicating mixed evidence.

curcuminoids — 1,000 mg

Curcuminoids are the family of phenolic pigments responsible for Turmeric's yellow color, consisting primarily of Curcumin (approximately 77%), demethoxycurcumin (17%), and bisdemethoxycurcumin (3%). Curcumin was first discovered from the Turmeric rhizome in 1815, with its structure proposed in 1910. As a polyphenol and diarylheptanoid, Curcumin is the most potent of the naturally occurring curcuminoids. For antioxidant defense, clinical evidence from multiple meta-analyses of RCTs shows Curcumin significantly reduces malondialdehyde (MDA) and raises enzymatic antioxidants such as SOD, catalase, and glutathione peroxidase. Its primary mechanistic pathway involves activation of the Nrf2-Keap1 signaling axis, upregulating endogenous antioxidant response elements. For arthritis and joint health, Curcumin is supported by a meta-analysis of 29 RCTs (2,396 participants across 5 arthritis types) confirming significant pain and inflammation reductions. A 2014 head-to-head RCT found 1,500 mg/day Curcumin equivalent to ibuprofen 1,200 mg/day in knee OA. It acts via NF-κB, COX-2, and 5-LOX inhibition. For chronic inflammation, multiple meta-analyses of RCTs demonstrate significant reductions in key inflammatory biomarkers — CRP, IL-6, and TNF-α — following Curcumin supplementation. Its core mechanism involves inhibition of the NF-κB signaling pathway and downstream pro-inflammatory cytokine cascades. For flexibility and mobility, a 2025 network meta-analysis (39 RCTs, 4,599 knee OA patients) confirmed Curcumin demonstrated benefits in joint function outcomes and was ranked among the most effective supplements. Multiple systematic reviews confirm it reduces inflammatory markers relevant to joint mobility. For cartilage health, Curcumin inhibits inflammatory cytokines (IL-1β, TNF-α, MMPs) that drive cartilage degradation, with a 2021 meta-analysis of 10 RCTs confirming curcuminoids significantly reduced WOMAC pain and stiffness. 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. For bursitis, Curcumin is cited by the Arthritis Foundation, with Ayurvedic use for joint inflammation well-documented over centuries.

Black pepper extract

Black pepper (Piper nigrum L.), often called the "King of Spices," has been used for thousands of years in Ayurvedic medicine and global culinary traditions. Its primary bioactive compound is piperine, an alkaloid responsible for pepper's pungent taste. Black pepper is listed by the FDA as generally recognized as safe (GRAS). Piperine's most well-documented pharmacological role is as a bioavailability enhancer. In human studies, co-administration of 20 mg piperine with 2 g Curcumin increased Curcumin blood concentrations by approximately 2,000%. The mechanism involves inhibition of CYP3A4, P-glycoprotein, and UDP-glucuronosyltransferase (UGT) — enzymes that would otherwise rapidly metabolize and eliminate Curcumin. For antioxidant defense, research suggests piperine scavenges free radicals, inhibits lipid peroxidation, and upregulates endogenous antioxidant enzymes. Human RCTs using Curcumin-piperine combinations show improvements in superoxide dismutase, total antioxidant capacity, and malondialdehyde in metabolic syndrome and chronic disease populations. For chronic inflammation, piperine inhibits key pro-inflammatory mediators including COX-2, IL-6, and prostaglandin E2. 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. For joint health, piperine inhibited IL-6, MMP13, COX-2, and PGE2 in human rheumatoid arthritis synoviocytes in vitro, and in rat arthritis models it significantly reduced paw edema and joint inflammation. A Curcumin-piperine human RCT also documented antioxidant improvements in 40 osteoarthritis patients.

dicalcium phosphate

Dicalcium phosphate serves as an excipient (inactive ingredient) in this formula. Calcium is the most abundant mineral in the human body, with over 99% stored in bone as hydroxyapatite. It plays essential roles in skeletal structure, muscle contraction, neuronal transmission, and cell signaling. In supplement formulations, Calcium phosphate compounds are commonly used as tablet or capsule fillers to aid in manufacturing consistency.

FAQ

Frequently asked questions

What makes this Turmeric Curcumin formula different from standard Turmeric supplements?

While most Turmeric supplements deliver high levels of Turmeric root powder with low levels of Turmeric extract, Nature's Sunshine Turmeric Curcumin delivers both Turmeric root and higher levels of the antioxidant-rich Turmeric extract. One serving is equivalent to 32,000 mg of whole root Turmeric, and the formula includes 1,000 mg of curcuminoids. Black pepper extract is also included to enhance bioavailability — human pharmacokinetic studies have shown piperine from Black pepper can increase Curcumin absorption by approximately 2,000%.

Why is Black pepper extract included in the formula?

Black pepper extract contains piperine, an alkaloid that inhibits enzymes (CYP3A4, UGT) and transporters (P-glycoprotein) responsible for rapidly metabolizing and eliminating Curcumin. By slowing this process, piperine significantly improves Curcumin's bioavailability. Research in humans found that piperine co-administration increased Curcumin blood levels by approximately 2,000% at 45 minutes post-dose. Black pepper may also offer its own antioxidant properties and aid with occasional digestive discomfort.

What does the research say about Curcumin and joint health?

Multiple randomized controlled trials and systematic reviews suggest Curcumin may support joint comfort and function. A 2022 meta-analysis of 29 RCTs involving 2,396 participants across five types of arthritis found Curcumin effective for pain and inflammation reduction. A 2025 network meta-analysis of 39 RCTs ranked Curcumin among the supplements with significant functional benefits for knee osteoarthritis. Some research also suggests comparable efficacy to NSAIDs, though evidence quality is generally rated as low to moderate due to variability in study formulations and designs.

Is this product suitable for vegetarians?

Yes, this formula uses VegCaps (vegetable capsules), making it suitable for vegetarians. The product also carries a non-GMO designation.

Are there any safety considerations with Turmeric Curcumin supplements?

Curcumin is generally well-tolerated. Several clinical trials have not shown toxic effects, and Curcumin is reported to be safe at doses of up to 6 g/day for 4–7 weeks. The most commonly reported side effects are mild gastrointestinal disturbances such as nausea or stomach upset, particularly at higher doses. However, rare cases of liver injury have been associated with Turmeric supplements, especially bioavailability-enhanced formulations. People with existing liver conditions, those taking blood-thinning medications, or those on drugs metabolized by CYP450 enzymes should consult a healthcare provider before use, as piperine may affect drug metabolism.

How much curcuminoid content does each serving provide?

Each serving of 2 VegCaps provides 1,100 mg of Turmeric extract containing 1,000 mg of curcuminoids — the primary active compounds in Turmeric responsible for its antioxidant and inflammatory-response-supporting properties.
