Klean Joint & Muscle by Klean Athlete

Runners with sore knees after mileage spikes, lifters with recurring elbow or shoulder aches, and anyone whose hs-CRP (a blood marker of inflammation) runs high after hard training are the best fit. This blend pairs turmeric with tamarind, tart cherry, and astaxanthin for joint comfort and muscle recovery. It’s most useful for active adults who want less day‑after soreness without using NSAIDs daily. If you need aggressive pain control for arthritis, this is an adjunct, not a stand‑alone fix.

Tart cherry concentrates are rich in anthocyanins, the red-purple pigments that dial down inflammatory signaling and reduce the enzymes that drive soreness. In studies, they trim post-workout DOMS (delayed-onset muscle soreness) and can lower creatine kinase (CK, a marker of muscle damage) after races. Astaxanthin, the red antioxidant from algae, sits in cell membranes and limits lipid peroxidation (fatty membrane damage), which correlates with faster recovery and less fatigue. The turmeric/tamarind combo targets joint comfort by calming inflammatory pathways in cartilage and synovial tissue.

Take two capsules daily with food. For joint pain, expect meaningful changes within 2 to 12 weeks, with steadier gains the longer you stay consistent. For race weeks or new training blocks, keep the daily dose and consider starting at least 3 to 7 days before the event for the tart cherry soreness benefit. Astaxanthin at 4 mg is a mid-range daily dose; some endurance data use 4 to 12 mg.

Turmeric and tamarind can have mild blood-thinning effects; use caution with warfarin, direct oral anticoagulants (blood thinners like apixaban or rivaroxaban), and antiplatelets (aspirin, clopidogrel). Avoid high-dose turmeric extracts if you have active gallbladder disease or bile duct obstruction. If you’re pregnant, planning surgery, or have reflux that worsens with spices, check with your clinician. Monitor blood pressure if you’re on antihypertensives, as astaxanthin can nudge it down slightly.
