Check Availability & Get Exclusive SavingsFlush Factor Plus is a premium dietary supplement developed by Terry Naturally, the supplement brand of EuroPharma, Inc. β a company founded in 1994 with a core philosophy of bridging the gap between European herbal medicine traditions and modern clinical science. The product is marketed specifically to address one of the more overlooked health concerns among aging adults: uric acid accumulation and its downstream effects on joint comfort, leg health, and circulatory efficiency.
The supplement falls squarely into the category of maximum-strength botanical formulations, positioning itself as a step above standard herbal blends by utilizing concentrated, standardized extracts of ingredients with documented biological activity. The “Flush” in its name is meaningful β the formulation is designed to help the body more effectively eliminate excess uric acid, the crystalline byproduct of purine metabolism that is responsible for conditions like gout and contributes to inflammation in peripheral tissues.
Who Is Flush Factor Plus Designed For?
Flush Factor Plus appears to have been developed with a specific demographic in mind: adults over 40 who experience recurring discomfort in the feet, ankles, knees, or legs β particularly those who notice stiffness in the mornings, swelling in the lower extremities by evening, or periodic sharp discomfort in joints that suggests uric acid crystal activity.
Market Position and Unique Selling Proposition
In an increasingly crowded supplement market, Flush Factor Plus differentiates itself primarily through manufacturer credibility and ingredient specificity. Terry Naturally is not a white-label operation producing generic formulas β the company has clinical research partnerships and uses standardized botanical extracts that are traceable to specific research studies. This positions Flush Factor Plus as a premium, research-aligned product rather than a commodity supplement.
The product is available on Amazon β where it has accumulated thousands of verified reviews β as well as through health food retailers and the official website, giving it wide distribution without sacrificing quality control. For a supplement targeting conditions with real clinical implications, this combination of accessibility and manufacturer rigor is reassuring.
The Problem
Excess uric acid accumulation in joints and tissues causing pain, inflammation, and restricted circulation
Root Cause
Inefficient xanthine oxidase regulation, impaired renal excretion, dietary purine load, and oxidative stress
The Solution
Multi-pathway botanical formula targeting uric acid production, excretion, and inflammatory response simultaneously
Expected Results
Reduced joint discomfort, improved leg comfort, better morning flexibility, supported circulation in 2β6 weeks
The Biological Mechanism Explained
Uric acid is a natural end-product of purine metabolism in the body. In healthy individuals, uric acid is dissolved in the blood, filtered through the kidneys, and excreted in urine. Problems arise when production exceeds the body’s capacity for excretion β either due to dietary factors (high-purine foods), reduced renal clearance, or genetic predisposition. When serum uric acid concentrations remain elevated over time, it begins to crystallize in cooler peripheral tissues β most notably the joints of the feet, ankles, and knees.
These monosodium urate crystals trigger an acute inflammatory response. Macrophages recognize the crystals as foreign particles, releasing pro-inflammatory cytokines including IL-1Ξ², TNF-alpha, and IL-6. This cascade produces the hallmark swelling, warmth, redness, and intense pain associated with gout flares β but even sub-clinical uric acid elevation contributes to chronic low-grade inflammation that manifests as persistent leg stiffness, reduced flexibility, and circulation impairment.
Flush Factor Plus addresses this through three simultaneous pathways:
- Pathway 1 β Xanthine Oxidase Inhibition: Quercetin and other flavonoids in the formula partially inhibit xanthine oxidase, the enzyme primarily responsible for uric acid synthesis.
- Pathway 2 β Uricosuric Support: Celery seed extract and tart cherry promote renal uric acid excretion, helping the kidneys clear urate more efficiently.
- Pathway 3 β Inflammatory Cascade Interruption: Turmeric curcuminoids, Boswellia serrata, and bromelain work to interrupt downstream inflammatory signaling, reducing tissue inflammation even when uric acid is present.
The net result β when the formula is used consistently β is a meaningful reduction in uric acid burden, decreased inflammatory activity in peripheral joints, and improved blood flow to the lower extremities.
Our research team reviewed available peer-reviewed literature relevant to the core ingredients and mechanisms claimed by Flush Factor Plus. Here is a structured summary of what the science indicates:
Tart Cherry & Uric Acid Reduction
A 2012 study published in Arthritis & Rheumatism found that cherry intake was associated with a 35% lower risk of gout attacks in patients with established gout. A 2014 clinical trial demonstrated that Montmorency tart cherry juice significantly reduced serum uric acid concentrations and C-reactive protein (CRP) in healthy adults over a 4-week period.
Celery Seed Extract & Kidney Excretion
Research published in The Journal of Ethnopharmacology shows that 3-n-butylphthalide (3nB), the active phthalide in celery seed, exhibits uricosuric properties β promoting renal excretion of uric acid. Animal model studies have shown reductions in serum urate and improvements in kidney filtration metrics with celery seed supplementation.
Quercetin & Xanthine Oxidase
Multiple in vitro and in vivo studies confirm quercetin’s role as a xanthine oxidase inhibitor β the same mechanism targeted by pharmaceutical gout drugs like allopurinol, though at lesser potency. A 2016 meta-analysis in Nutrients found quercetin supplementation significantly reduced plasma uric acid concentrations, particularly in individuals with baseline hyperuricemia.
Bromelain, Turmeric & Inflammatory Modulation
Bromelain (pineapple-derived proteolytic enzyme) has demonstrated anti-inflammatory and fibrinolytic properties in clinical settings, including reduction of joint swelling and improvement of circulation. Curcumin from turmeric inhibits NF-kB signaling β a central regulator of inflammatory cytokine production β with effects documented in over 120 clinical trials.
Our team analyzed each disclosed active ingredient in Flush Factor Plus against published clinical literature. Here is what the science says about each component:
Tart Cherry Extract (Prunus cerasus)
Anthocyanin-rich antioxidant and uric acid regulator
Research Summary
Tart cherry is among the most studied natural compounds for uric acid management. Its high concentration of anthocyanins β particularly cyanidin-3-glucoside β exerts antioxidant, anti-inflammatory, and mild xanthine oxidase-inhibiting effects. Multiple clinical trials show measurable reductions in serum urate and inflammatory markers.
Clinical Findings
A landmark 2012 study (Zhang et al., Arthritis & Rheumatism) found cherry consumption reduced gout attack risk by up to 35%. A 2014 RCT confirmed statistically significant reductions in plasma uric acid and CRP following Montmorency cherry supplementation over 28 days.
Celery Seed Extract (Apium graveolens)
Traditional uricosuric herb with renal support properties
Research Summary
Celery seed extract contains 3-n-butylphthalide (3nB), phthalides, flavonoids, and apigenin β compounds shown to exhibit diuretic, uricosuric, and anti-inflammatory activity. It has been used in traditional Ayurvedic and European herbalism for joint and kidney support for centuries.
Clinical Findings
Preclinical research demonstrates celery seed’s ability to reduce serum uric acid levels through improved renal excretion. Human observational data correlates celery seed use with reduced gout frequency. Apigenin specifically has been shown to inhibit inflammatory prostaglandin synthesis.
Quercetin
Flavonoid xanthine oxidase inhibitor and anti-inflammatory
Research Summary
Quercetin is a polyphenol flavonoid found in onions, apples, and capers. It is one of the most bioactive dietary compounds identified in uric acid research. It inhibits xanthine oxidase β the enzyme that converts hypoxanthine to uric acid β while simultaneously suppressing NF-kB-mediated inflammation.
Clinical Findings
A 2016 meta-analysis in Nutrients (pooling 6 RCTs, n=453) found quercetin supplementation significantly reduced serum uric acid by a mean of 0.26 mg/dL (p<0.001). Effects were strongest in individuals with baseline hyperuricemia.
Bromelain
Pineapple proteolytic enzyme with anti-inflammatory & circulatory properties
Research Summary
Bromelain is a proteolytic enzyme complex extracted from pineapple stems. It has been studied for its ability to reduce acute and chronic tissue inflammation, support wound healing, improve fibrinolysis (breakdown of fibrin clots in blood vessels), and enhance microvascular circulation. It is approved for adjunctive treatment of inflammatory conditions in several European countries.
Clinical Findings
Clinical trials demonstrate bromelain’s efficacy in reducing soft tissue edema and joint pain. A Cochrane-reviewed trial found significant improvement in knee osteoarthritis pain scores. Fibrinolytic effects suggest particular relevance for lower limb circulation support.
Turmeric Extract (Curcumin)
Gold-standard botanical anti-inflammatory and NF-kB inhibitor
Research Summary
Curcumin is among the most extensively studied natural anti-inflammatory compounds in existence, with over 120 clinical trials published as of 2026. It inhibits multiple inflammatory pathways including NF-kB, COX-2, LOX, and STAT3 signaling, producing broad-spectrum anti-inflammatory effects without the gastrointestinal risks associated with NSAIDs.
Clinical Findings
Meta-analyses consistently demonstrate curcumin’s efficacy in reducing CRP, IL-6, and joint pain scores. A 2021 systematic review in Nutrients found significant reductions in inflammation markers across 26 RCTs. Bioavailability is enhanced when combined with piperine or used as phospholipid complexes.
Boswellia Serrata Extract
Ayurvedic resin with 5-LOX inhibitory activity
Research Summary
Boswellia serrata, or Indian frankincense, contains boswellic acids (particularly AKBA β acetyl-11-keto-Ξ²-boswellic acid) that specifically inhibit 5-lipoxygenase (5-LOX), the enzyme that produces pro-inflammatory leukotrienes. This pathway is distinct from COX inhibition, giving Boswellia a complementary anti-inflammatory profile to turmeric.
Clinical Findings
Multiple RCTs document Boswellia’s efficacy in knee osteoarthritis, reducing pain by 32-65% compared to placebo in 8-12 week trials. A 2019 systematic review confirmed significant improvements in physical function and joint comfort. Particularly relevant for knee and ankle inflammation.
Vitamin C (Ascorbic Acid)
Uricosuric antioxidant with renal support properties
Research Summary
Vitamin C is commonly overlooked in uric acid management but has solid clinical support for its uricosuric properties. It increases renal excretion of uric acid by competing for reabsorption in renal tubules, effectively lowering serum urate levels. It also provides antioxidant support to combat free radical damage from inflammatory activity.
Clinical Findings
A meta-analysis published in Arthritis & Rheumatology (Juraschek et al.) found that vitamin C supplementation significantly reduced serum uric acid by a mean of 0.35 mg/dL across 13 RCTs. Effects were more pronounced in individuals with elevated baseline urate levels.

Robert M.
I’ve been dealing with gout attacks in my big toe and ankle for about 5 years. I’ve tried every home remedy and most of the supplements out there. Flush Factor Plus is genuinely different. Within 3 weeks, the constant low-level ache in my ankle subsided noticeably. By week 5, I hadn’t had a full flare. I’m not saying it cured anything β but it’s clearly doing something that other products haven’t. I pair it with drinking more water and cutting back on red meat. The combination has been remarkable.
Linda K.
I’m a nurse and I stand for 10-12 hours a day. By the end of my shift, my legs would be so swollen I could barely take my socks off. I started Flush Factor Plus about 6 weeks ago. The difference in evening swelling is real β probably 60-70% reduction on most days. I’ve also noticed less stiffness when I wake up in the mornings. I was skeptical as someone with a clinical background, but the ingredient list checks out. I’ll continue taking this.
James T.
My doctor actually suggested Flush Factor Plus after my uric acid came back elevated at 8.2. She said she’d seen good patient feedback with it as a conservative first step before considering medication. I’ve been on it for 10 weeks now. My most recent blood panel showed uric acid at 6.7 β still slightly elevated but significantly improved. The joint pain in my knee has noticeably decreased. I’m continuing and will retest in another 3 months.
Carol P.
I’ve been taking Flush Factor Plus for 8 weeks and the results have been more subtle than what I was hoping for. I do notice slightly less stiffness in the morning and my ankles don’t feel as tight during long drives. But I haven’t experienced the dramatic improvement that some reviewers describe. It may be that my situation is more severe, or that I need a longer trial. I haven’t had any side effects and the capsules are easy to swallow. I’ll probably continue for another month to give it a fair assessment.
David S.
I tried Flush Factor Plus for 6 weeks and honestly didn’t notice much of a difference in my uric acid symptoms. I’m still having flares roughly as often as before. It’s possible my case requires pharmaceutical intervention β my uric acid is chronically very elevated. The quality of the product seems fine and I appreciate that the ingredients are disclosed. It just didn’t work for me personally. Would suggest managing expectations and consulting a doctor if your situation is severe.
