Active Ingredients

  • Potassium

    98 mg

    Ingredient research · Potassium

    Potassium is an essential electrolyte that helps regulate fluid balance, nerve signaling, and muscle contraction, including the heartbeat. Supplementation is most useful for preventing or correcting low potassium when intake is inadequate or losses are increased, while adequate potassium intake also contributes to healthy blood pressure.

    • Supports blood-pressure control, particularly in adults with hypertension and higher sodium or lower potassium intake.
    • Supports selected vascular-function responses after high-sodium meals in healthy adults.

  • Methyl Sulfonyl Methane

    850 mg

    Ingredient research · MSM

    MSM is a sulfur-containing compound used mainly to ease joint discomfort and stiffness, particularly in osteoarthritis. Supplementation may modestly improve pain and physical function for some people, while proposed benefits for exercise recovery, skin health, and inflammation are less established.

    • Supports total-symptom and physical-function outcomes in knee osteoarthritis.

  • Glucosamine Sulfate

    750 mg

    Ingredient research · Glucosamine Sulfate 2KCl

    Glucosamine Sulfate 2KCl is a potassium chloride–stabilized form of glucosamine sulfate, a building-block compound used mainly for osteoarthritis. It may modestly reduce knee pain and improve function with sustained use, although findings differ among formulations and it has not been shown to rebuild cartilage.

  • Indian Frankincense extract

    350 mg

    Ingredient research · Boswellia serrata

    Boswellia serrata supplements are typically extracts of the tree’s gum resin, containing boswellic acids that influence inflammatory pathways. They may modestly reduce osteoarthritis pain and stiffness and improve joint function; potential benefits for respiratory and digestive inflammatory conditions are less established.

  • Curcumin Phytosome Complex

    From Curcuma longa extract

    From Phospholipid

    250 mg
  • Bromelain

    200 mg

    Ingredient research · Bromelain

    Bromelain is a mixture of protein-digesting enzymes, not a single compound, whose proteolytic activity underlies its use as a digestive aid and its proposed anti-inflammatory effects. It may modestly ease swelling and discomfort following some surgeries and may benefit joint or sinus symptoms, though effects are context-dependent.
