Overview

NOW Curcumin Turmeric: What It Is and Why It Matters

Nature's Sunshine Turmeric Curcumin harnesses the power of Turmeric extract to promote a healthy inflammatory response. If you've been exploring now Curcumin Turmeric options, this formula stands out because one serving is equivalent to 32,000 mg of whole root Turmeric — delivering both Turmeric root and higher levels of the antioxidant-rich Turmeric extract rather than relying on high levels of Turmeric with low levels of extract.

Curcuminoids are the primary active ingredients obtained from the rhizomes of the yellow curry spice Turmeric (Curcuma longa L.). Curcumin has been safely used for centuries in Indian Ayurvedic medicine, where it has been traditionally employed for its anti-inflammatory, analgesic, and wound-healing properties. In Ayurveda, Turmeric is regarded as a remedy for digestive disorders, arthritis, skin conditions, and inflammatory issues.

This formula is clinically studied and designed to deliver superior absorption and effectiveness. As an added benefit, it includes Black pepper extract from the Piper nigrum species, which research suggests may increase the absorption of Curcumin by up to 2,000% in humans. The product is non-GMO and comes in a 60-count VegCap format.

How It Works

Supporting a Healthy Inflammatory Response and Antioxidant Defense

The science behind now Curcumin Turmeric centers on Curcumin's ability to modulate multiple signaling pathways involved in inflammation. Research suggests Curcumin exerts its core anti-inflammatory effects primarily by inhibiting the activation of the NF-κB signaling pathway, regulating the MAPK/ERK phosphorylation cascade, and modulating the JAK/STAT pathway. It also suppresses the activity of COX-2 and LOX enzymes, which are responsible for producing inflammatory mediators including prostaglandins and leukotrienes.

On the antioxidant side, studies suggest Curcumin activates the Keap1-Nrf2/ARE transcriptional pathway, which upregulates endogenous cytoprotective enzymes. Multiple human randomized controlled trials have shown it may measurably raise total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase, and glutathione while lowering the lipid-peroxidation marker malondialdehyde (MDA).

One of Curcumin's biggest challenges is its poor oral bioavailability — due to low water solubility, poor intestinal permeability, and rapid metabolism. That's precisely why this formula includes Black pepper extract. Research suggests piperine from Black pepper inhibits glucuronidation (the metabolic process that tags Curcumin for rapid excretion), potentially increasing Curcumin bioavailability by up to 2,000% in humans.

It's important to note that while in-vitro and animal studies show potent effects, these events often occur at concentrations that may not be easily achieved in the human body through oral dosing. The enhanced-delivery approach of this formula — pairing concentrated curcuminoids with Black pepper extract — is designed to help bridge that gap.

What's inside

Key ingredients

tumeric extract — 1,100 mg
Turmeric (Curcuma longa L.) is a rhizomatous herbaceous perennial of the ginger family, used for nearly 6,000 years in Ayurvedic, traditional Chinese, and Southeast Asian medicine for digestive, respiratory, circulatory, and skin conditions. In standardized extracts, Curcumin generally represents 75–80% of total curcuminoids. Research suggests Turmeric extract supports a healthy inflammatory response by inhibiting NF-κB, COX-2, and 5-LOX pathways and reducing pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6. For joint health, multiple systematic reviews and meta-analyses of RCTs demonstrate consistent improvements in knee osteoarthritis pain, stiffness, and function compared to placebo — with some trials showing effects comparable to NSAIDs. A 2022 meta-analysis of 29 RCTs (2,396 participants across five types of arthritis) confirmed its efficacy across multiple arthritis types. A 2025 network meta-analysis of 39 RCTs (4,599 knee OA patients) ranked Curcumin among supplements with significant benefits for joint function and mobility. Research also suggests Turmeric extract supports antioxidant defense through the Keap1-Nrf2/ARE pathway, raising endogenous antioxidant enzymes while lowering oxidative stress markers. Additionally, studies suggest it may support cartilage health by inhibiting inflammatory cytokines and enzymes that drive cartilage degradation, with one landmark RCT (n=367) finding Turmeric extract equivalent to ibuprofen 1,200 mg/day for knee pain relief. Traditionally, Turmeric has been used in Ayurveda and Unani medicine for liver conditions, ulcers, inflammation, cough, cold, skin infections, and blood purification.
curcuminoids — 1,000 mg
Curcuminoids are the polyphenolic pigments responsible for Turmeric's yellow color, consisting primarily of Curcumin (approximately 77%), demethoxycurcumin (17%), and bisdemethoxycurcumin (3%). Curcumin was first isolated from Turmeric rhizome in 1815, and its structure was proposed in 1910. Research suggests curcuminoids support a healthy inflammatory response through multi-target mechanisms — inhibiting NF-κB, MAPK, NLRP3 inflammasome, and COX-2 pathways while activating antioxidant pathways like Nrf2. For joint health, a meta-analysis of 29 RCTs confirmed significant pain and inflammation reductions across five types of arthritis, while 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. A 2025 meta-analysis of 21 studies (1,705 patients) found CRP and TNF-alpha levels were significantly lower in Curcumin groups compared to placebo in knee OA. Research also suggests curcuminoids may support metabolic health — a meta-analysis of 13 RCTs in metabolic syndrome patients found significant improvements in waist circumference, fasting blood sugar, HDL-C, TNF-α, CRP, and malondialdehyde. A 2021 meta-analysis confirmed curcuminoids significantly reduced WOMAC pain and stiffness, and the European Society for Clinical and Economic Aspects of Osteoporosis (ESCEO) recognizes curcuminoids as an OA nutraceutical. For gut health, research suggests Curcumin may serve as an effective adjunctive therapy in ulcerative colitis — a systematic review of six RCTs (385 patients) found it effectively induced clinical remission. Curcuminoids have been traditionally used in Ayurvedic medicine for treatment of skin wounds, inflammation, and joint conditions for over 4,000 years.
Black pepper extract
Black pepper (Piper nigrum L.), often called the "King of Spices," contains the alkaloid piperine as its major bioactive compound. Its most clinically documented benefit is enhancing the bioavailability of co-administered nutrients. In one landmark human study, co-administration of 20 mg piperine with Curcumin increased Curcumin bioavailability by 2,000% — from 0.25 to 1 hour post-administration. The mechanism is well-characterized: piperine inhibits UDP-glucuronosyltransferase (UGT) enzymes that would normally tag Curcumin for rapid excretion, and also inhibits CYP3A4 and P-glycoprotein efflux transporters. Beyond bioavailability enhancement, research suggests piperine has its own anti-inflammatory activity through suppression of COX-2 gene expression and enzyme activity, and has inhibited IL-6, MMP13, COX-2, and PGE2 in human rheumatoid arthritis synoviocytes in vitro. 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. Piperine also demonstrates antioxidant properties — human RCTs using Curcumin-piperine combinations show improvements in superoxide dismutase, total antioxidant capacity, and malondialdehyde in chronic disease populations. In Ayurvedic tradition, Black pepper (known as Maricha) has been used for thousands of years in approximately two-thirds of all traditional Ayurvedic formulations for its digestive and bioenhancing properties. Black pepper is listed by the FDA as generally recognized as safe (GRAS).
dicalcium phosphate
Dicalcium phosphate is a Calcium compound used here as a supplement excipient. Calcium is the most abundant metal in the human body, with over 99% stored in bone as hydroxyapatite. It plays essential roles in muscle contraction, neuronal transmission, cell signaling, and hormonal regulation. In this formula, dicalcium phosphate serves as a processing agent to support the capsule's integrity and consistency.

FAQ

Frequently asked questions

Why is Black pepper extract included in this now Curcumin Turmeric formula?

Black pepper extract contains piperine, an alkaloid that research suggests may increase Curcumin bioavailability by up to 2,000% in humans. Piperine works by inhibiting the enzymes (particularly UDP-glucuronosyltransferase) that normally tag Curcumin for rapid excretion from the body. Without an absorption enhancer like piperine, Curcumin's inherently poor water solubility and rapid metabolism significantly limit how much reaches systemic circulation.

What makes this Turmeric supplement different from plain Turmeric powder?

While raw Turmeric powder contains only about 2–5% curcuminoids by weight, this formula delivers a concentrated Turmeric extract with 1,000 mg of curcuminoids per serving — equivalent to 32,000 mg of whole root Turmeric according to the manufacturer. It also includes Black pepper extract to support bioavailability, addressing one of the most significant challenges with standard Turmeric supplementation.

What does the research say about Curcumin and joint health?

Multiple systematic reviews and meta-analyses of randomized controlled trials support a statistically significant benefit of Curcumin for joint comfort and function, particularly in knee osteoarthritis. A 2022 meta-analysis of 29 RCTs (2,396 participants across five arthritis types) confirmed its efficacy, and some studies have found effects comparable to NSAIDs. However, evidence quality is generally rated low to very low due to small sample sizes, formulation differences, and methodological variability across studies.

Is Curcumin safe to take daily?

Several human trials have not shown toxic effects, and Curcumin is reported to be safe at doses up to 6 g/day orally for 4–7 weeks. The FDA has classified Curcumin as generally recognized as safe (GRAS). The most commonly reported side effects in clinical trials are mild gastrointestinal disturbances such as nausea, diarrhea, and stomach upset, particularly at higher doses. However, individuals with existing liver conditions or those taking medications (especially anticoagulants or drugs metabolized by CYP3A4 enzymes) should consult a healthcare professional before use, as piperine can affect how certain medications are metabolized.

Can I take this formula alongside other supplements or medications?

Because this formula contains Black pepper extract (piperine), which inhibits CYP3A4 and P-glycoprotein, it has the potential to increase plasma concentrations of certain co-administered drugs, including carbamazepine, warfarin, and other medications. We always recommend talking with a healthcare provider before combining supplements with prescription medications. Our naturopath is available for a free consultation if you'd like personalized guidance.

Does this formula support gut and immune health?

Research suggests Curcumin may support gastrointestinal health. A systematic review of RCTs found Curcumin effectively induced clinical remission in ulcerative colitis patients when used as an adjunctive therapy. The product highlights also note that it may promote healthy microbiome balance. For immune function, Curcumin's documented ability to modulate inflammatory pathways — including NF-κB and pro-inflammatory cytokines like TNF-α and IL-6 — supports its role in immune system wellness.
