By far the best Joint supplement I've ever used, nothing even comes close. Great brand, clean ingredients and highly effective!

Try Joint Performance Fuel for 90 days. If your joints don't feel better, send back whatever's left — even an empty bag — and we'll refund every cent. No return fees, no hassle, no awkward questionnaire. We give you 90 days because that's how long the science says it takes for all four ingredients to do their full job.

Joint Performance Fuel combines four ingredients backed by 50+ clinical trials, each chosen because it works on a different mechanism behind joint pain and stiffness:

  • Meriva® Curcumin (1,000 mg) — Inhibits COX-2 and NF-κB inflammatory pathways. In an 8-month study, WOMAC pain and function scores improved by over 50%.
  • AprèsFlex® Boswellia (100 mg) — Inhibits 5-LOX, the inflammation pathway curcumin doesn't touch. Pain reduction has been measured as early as day 5.
  • UC-II® Undenatured Type II Collagen (40 mg) — Works through the immune system (oral tolerance) to slow cartilage breakdown. In a head-to-head trial, it outperformed 1,500 mg glucosamine + 1,200 mg chondroitin on every measure.
  • Levagen+® PEA (350 mg) — Activates the body's PPAR-α receptor and modulates the endocannabinoid system. Recent meta-analyses show meaningful pain reduction at 6, 8, and 24+ weeks.

Most joint formulas pick one mechanism. Joint Performance Fuel covers four — anti-inflammatory, structural, immune-modulating, and endocannabinoid — at clinically studied doses, in their branded forms.

Joint Performance Fuel is manufactured in a GMP-certified facility and third-party tested for purity, potency, and contaminants. In clinical trials, all four active ingredients showed side-effect rates comparable to placebo.

A few practical notes:

  • If you take blood thinners (like warfarin) or statins, check with your doctor before starting. Curcumin can affect how those medications work.
  • Boswellia, UC-II, and PEA have minimal known drug interactions, which is part of why we built the formula around them.
  • Not intended for use during pregnancy, while breastfeeding, or by anyone under 18.

If you have a medical condition or take prescription medication, talk to your healthcare provider before starting any new supplement.

How long until I feel a difference?
Most people notice changes within 2–4 weeks. Boswellia can show effects as early as 5–7 days, while UC-II builds gradually over 60–90 days as it works on the immune-cartilage connection. The full benefit comes from taking it consistently for at least 90 days — which is exactly how long our guarantee covers you.

How do I take it?
Three capsules once a day, with food. Food helps absorption — especially for the Curcumin and PEA, which are fat-soluble.

Can I take it with other supplements?
Yes. It pairs especially well with omega-3 fish oil and collagen peptides, which support pathways our capsules don't cover.

Is it vegetarian or vegan?
The capsule and excipients are vegetarian-friendly, but the formula isn't vegan — UC-II is sourced from chicken cartilage.

What if it doesn't work for me?
You're covered by our 90-day guarantee. Send back what's left for a full refund, even if the bag is empty.

Can I take it long-term?
Yes. All four ingredients have strong long-term safety data, and joints respond best to consistent ongoing support rather than start-and-stop use.

Why are there four ingredients instead of glucosamine and chondroitin?
Two reasons. First, in the only direct head-to-head trial, UC-II at 40 mg outperformed 1,500 mg glucosamine + 1,200 mg chondroitin. Second, ACR and OARSI clinical guidelines recommend against most US-available glucosamine/chondroitin products because supplement-grade quality is too variable. We chose ingredients with stronger and cleaner evidence.

What's inside
FOUR MECHANISMS.
FOUR BRANDED INGREDIENTS.
ZERO GUESSWORK.

No supplement on the market combines all four of these clinically studied ingredients. We researched 40+ brands and 60+ SKUs. The closest competitors cover two or three at best.

1,000 mg/day delivering ~200 mg curcuminoids

The deepest evidence base of any joint supplement ingredient. An umbrella meta-analysis of 11 prior meta-analyses confirmed significant reductions in pain, stiffness, and function. Proven comparable to prescription NSAIDs — with zero GI side effects.

50%+
WOMAC score reduction in 8-month clinical study. The gold standard used by Thorne, Jarrow, and Momentous.
100 mg/day — the lowest effective dose of any ingredient

Covers the second major inflammatory cascade that curcumin doesn't touch. Benefits appear as early as day 5 — the fastest onset of any botanical studied. Effects persisted a full month after stopping, suggesting possible disease-modifying action.

61.7%
WOMAC pain reduction. Safest high-efficacy option for adults taking blood thinners, statins, or diabetes meds.
40 mg/day — only 40 mg needed

Outperformed glucosamine + chondroitin in a head-to-head 191-patient RCT. Works through a unique mechanism: tiny doses of native collagen reprogram T-cells to stop immune-mediated cartilage destruction. 40 mg adds virtually no capsule burden.

41%
Pain reduction in the landmark Lugo 2016 trial — outperforming glucosamine + chondroitin on every measure.
350 mg micronized with LipiSperse® technology

The most compelling emerging ingredient in joint health. A 2025 meta-analysis found significant pain reduction at 6, 8, and 24 weeks. Works through PPAR-α receptor activation — a mechanism entirely distinct from every other ingredient in this formula.

1.75×
Greater absorption than standard PEA via cold-water dispersibility technology. No major brand combines PEA with joint ingredients — until now.
What to expect
REAL TIMELINES.
NOT MIRACLE PROMISES.

Each ingredient activates on its own timeline. Here's what the clinical research says you can expect — not what marketing says you want to hear.

DAY 5Morning stiffness starts to ease
AprèsFlex Boswellia is the first ingredient to kick in. It calms one source of joint swelling — the kind that builds up while you sleep. That's why mornings feel so stiff. By day 5, most people start to feel them loosen up.
WEEKS 2–4Daily aches start to fade
Now Meriva Curcumin joins in. It calms a second source of joint swelling. PEA starts working too — it turns down pain signals in your body. Together, they take the edge off your day-to-day aches and soreness.
WEEKS 4–8Stairs, mornings, and workouts feel easier
Your body now has less swelling overall. Most people don't need a test to feel it — they just notice life gets easier. Stairs feel easier. Mornings feel less stiff. You bounce back faster from a workout or a long day on your feet.
MONTHS 2–3Long-term cartilage protection kicks in
This is when UC-II hits its full effect. It teaches your immune system to stop wearing down your own cartilage — the soft cushion between your bones. This is the kind of support that lasts.
MONTH 3+All four ingredients at full strength
Now all four ingredients are working at full power. Your cartilage keeps getting more support. Swelling stays low. The longer you stay on it, the better you feel. This is the long-term win.

Ingredients in this category proven comparable to NSAIDs

AS EFFECTIVE AS NSAIDS. WITHOUT THE GI SIDE EFFECTS.

Multiple head-to-head clinical trials have shown supplement ingredients performing comparably to prescription-strength anti-inflammatories — with significantly fewer side effects. Here are three from our ingredient stack:

Curcumin (BCM-95, 1,500mg)
vs. Diclofenac 100mg/day
Non-inferior with zero GI side effects vs. the NSAID group (Shep 2019, n=139)
Curcumin (C. domestica, 1,500mg)
vs. Ibuprofen 1,200mg/day
Non-inferior; fewer GI complaints at p=0.046 (Kuptniratsaikul 2014, n=367)
Boswellia 1,000mg
vs. Valdecoxib 10mg/day
Non-inferior; benefit persisted 1 month after stopping therapy (Sontakke 2007, n=66)
Questions
STRAIGHT ANSWERS.
NO BS.

Glucosamine and chondroitin target one pathway — structural cartilage support. Still In The Game covers four distinct mechanisms: two anti-inflammatory pathways (COX-2 and 5-LOX), immune-mediated cartilage protection (oral tolerance), and endocannabinoid pain modulation. In fact, one of our ingredients — UC-II collagen — outperformed the glucosamine + chondroitin combination in a head-to-head clinical trial of 191 patients.

Three of our four ingredients — Boswellia, UC-II, and PEA — have minimal drug interaction risk, making them well-suited for adults taking blood thinners, statins, or diabetes medications. Curcumin has a moderate interaction profile, particularly with warfarin and certain statins. We always recommend discussing any new supplement with your healthcare provider, especially if you're taking prescription medications.

Based on clinical research: Boswellia (AprèsFlex) can begin working as early as day 5. Curcumin and PEA typically show effects in weeks 2–4. UC-II takes 60–90 days to fully establish oral immune tolerance. We designed this formula so you get fast-acting relief from Boswellia while the longer-building ingredients establish deeper, structural benefits over time. Give it the full 90 days — that's why our guarantee covers the entire period.

We offer a full 90-day money-back guarantee. Not 30 days — 90. Because UC-II takes 60–90 days to fully establish its mechanism, and we want you to experience the complete formula working together before making a judgment. If you're not satisfied for any reason, we'll refund your purchase in full. No hoops, no hassle.

Still In The Game is designed to be a complete joint formula — no stacking required. Most people replace their existing supplements with this single product. If you're currently taking a standalone omega-3, you can continue that alongside our formula for additional benefit. As always, check with your healthcare provider about your specific supplement stack.
