Product Description
Back-to-back training days are where fitness is built — and where joints and muscles get put to the test. Most athletes have learned to manage the soreness. What they haven't solved is the slow, grinding accumulation of inflammation that chips away at mobility, flexibility, and range of motion over weeks and months of hard training. That nagging knee. That stiff hip. The shoulder that never fully loosens up before the swim start.
Klean Joint & Muscle is a four-ingredient, all-plant-based formula built specifically for athletes who train regularly and need their bodies to keep moving well — not just recover, but stay mobile and functional through the entire season.
Clinically Studied Joint Relief – TamaFlex® is a patented blend of tamarind seed extract and turmeric root — two botanicals from Ayurvedic tradition that work together to target the two main inflammation pathways (COX-2 and 5-LOX) that drive joint discomfort. In three published clinical studies, TamaFlex delivered measurable improvements in joint comfort, stiffness, and range of motion in as little as five days. Each serving of Klean Joint & Muscle provides 400 mg — a clinically relevant dose.
Natural Muscle Recovery – VitaCherry® delivers 480 mg of whole tart cherry fruit — the anti-inflammatory compounds that give tart cherries their power. These natural antioxidants help dial down the muscle soreness and oxidative stress that accumulate after hard efforts, supporting faster recovery between sessions.
Elite Antioxidant Protection – Astaxanthin from AstaReal® is one of the most potent natural antioxidants available — significantly more powerful than vitamin C or vitamin E at neutralizing the free radicals generated during intense exercise. At 4 mg per serving from sustainably sourced microalgae, it supports both muscle and joint tissue at a cellular level.
How to Use Klean Joint & Muscle
Dose: Take 2 capsules daily, with a meal. For best results, use consistently every day — the benefits of TamaFlex and tart cherry compounds build cumulatively over time, with noticeable improvements typically felt within 5–14 days of daily use. Athletes in high-volume training blocks or those managing chronic joint discomfort can stack this with Klean Collagen + C for complementary connective tissue support.
Pro tip: Take with your evening meal to let the anti-inflammatory compounds work overnight while your body is already in recovery mode.

Klean Athlete Joint & Muscle FAQ's
Everything you need to know about Klean Athlete Joint & Muscle.
Klean Joint & Muscle is a plant-based joint and recovery supplement built around four patented ingredients — VitaCherry tart cherry, TamaFlex tamarind and turmeric blend, and AstaReal astaxanthin — designed specifically for athletes who train regularly and need support for joint comfort, muscle recovery, and cartilage health.
VitaCherry whole tart cherry delivers the anti-inflammatory compounds that give tart cherries their recovery reputation, supporting muscle soreness reduction after hard efforts. TamaFlex combines tamarind seed extract and turmeric root extract to support joint flexibility and comfort, while AstaReal astaxanthin — a powerful antioxidant from algae — helps protect muscle tissue from oxidative stress during training.
Astaxanthin is one of the most potent natural antioxidants known, derived from Haematococcus algae, and it works by neutralizing the oxidative damage that accumulates in muscle and joint tissue during sustained training. AstaReal is the clinically studied, patented form used in Klean Joint & Muscle — not the generic versions found in cheaper supplements.
Yes. Like all Klean Athlete products, Joint & Muscle is NSF Certified for Sport, meaning every batch is independently tested for banned substances, label accuracy, and contaminants. For competitive athletes subject to drug testing, that certification matters.
Joint and recovery support supplements work cumulatively — most athletes notice meaningful improvements in joint comfort and post-session recovery within four to six weeks of consistent daily use. Tart cherry and turmeric research consistently points to multi-week timelines for full effect.
