Peak Flexibility Performance Across All Lifestyles

Unlike typical joint supplements, Flex is a flexibility formula for all lifestyle-related joint concerns:

Strength training : Lifting can tweak shoulders and backs, limiting gym time and gains.

Endurance activities : Long-distance running and others impact knees, hips and ankles.

Tech usage : Texting, tapping and typing can strain connective tissues in fingers and wrists.

Professional activities : From desk jobs to manual labor, repetitive motions may strain joints.

Active 55+ : Age-related joint and mobility problems can significantly impair quality of life.

Designed for performance, Flex helps keep you moving by targeting several key pathways for joint health and flexibility:

Knee Structure

Ingredients

Supplement Facts
Other Ingredients

1. Soothing Botanicals for Natural Joint Comfort

AprèsFlex® Boswellia Serrata, 100 mg

Desert tree Boswellia Serrata produces a gum resin containing active boswellic acids, with AKBA (3-O-acetyl-11 keto-ß-boswellic acid) as the most effective for joint health. AKBA helps joints by:

  1. Modulating immune responses to help protect and soothe joints;
  2. Blocking 5-LOX, an enzyme that eats away at cartilage over time;
  3. Limiting matrix metalloproteinase (MMP) enzyme that weakens connective tissues

Boswellia Serrata has been linked to improvements in joint aches, flexion and performance of daily activities in human clinical research.

ApresFlex® Boswellia Serrata

3-0-acetyle-11 keto-boswellic acid - AKBA soothes joints and protects against cartillage and connective tissue damage.

Performance Lab® Flex AprèsFlex® leverages advanced nutritional technology to achieve 52% greater absorption than plain Boswellia. It is also standardized to 20% AKBA for reliable joint benefits.

CurcuWIN® Curcumin, 250 mg

Ayurvedic root spice Turmeric gets its bright yellow color from plant pigments called curcuminoids. Curcumin is the primary curcuminoid suggested to help joint health and flexibility by:

  1. Fighting joint-destructive free radicals with potent antioxidant activity;
  2. Regulating COX-2 enzyme to soothe achy joints;
  3. Protecting cartilage cells from destructive matrix metalloproteinase (MMP) enzymes;
  1. Supporting synthesis of collagen and other structural joint proteins;
  2. Reducing advanced glycation end-products (AGEs) that stiffen connective tissues

Curcumin has been linked to improvements in joint stiffness, comfort and overall functional performance in human clinical research.

Performance Lab® Flex CurcuWIN® is an ultramodern nutritional innovation that makes curcumin 46X more absorbable. CurcuWIN® is also standardized to 20% curcuminoids in turmeric-identical ratios.

CurcuWIN®

Curcumin - Human trials suggest Curcumin enhances joint flexibility and comfort.

Performance Lab® Flex Advanced Botanical Stack
AprèsFlex® Boswellia Serrata + CurcuWIN® Curcumin

  • Extensively researched: Both have been used in herbalism for centuries; both have demonstrated joint benefits in multiple modern studies, including in combination.
  • Combination benefits: Work better together by targeting the same flexibility pathways with unique bioactivities that help individually and in tandem.
  • Safer, healthier and easier to take: Some synthetics for joint aches can upset the stomach and disrupt proteins that are needed to repair cartilage.

With AprèsFlex® Boswellia Serrata + CurcuWIN® Curcumin, Performance Lab® Flex supplies the two best forms of the two best joint-supportive botanicals known to science.

2. Maintenance Support for Healthy Joint Structure

Beyond botanical support, Flex supplies building blocks Glucosamine. Chondroitin and MSM – the most evidence-backed joint stack known to science – plus mineral Strontium to support joint function, strength and renewal over time:

Glucosamine Sulfate 2KCI (from corn), 500 mg

Glucosamine is an amino sugar naturally found in the tissues that surround, cushion and support the joints – including cartilage, ligaments, tendons and synovial fluids. Glucosamine supports:

  1. Building-block proteins that are used to form connective tissues;
  2. Chondrocyte cells within joints that repair and regenerate cartilage;
  3. Joint-lubricating synovial fluid for smooth, comfortable range of motion

Flex. Glucosamine is vegan Most glucosamine is sourced from shellfish. Flex instead supplies the research-backed Glucosamine Sulfate form sourced from a clean alternative: Corn.

CurcuWIN®

Glucosamine Sulfate - Glucosamine Sulfate cushions, lubricates and supports strong joints.

Mythocondro® Chondroitin Sulfate, 100 mg

Chondroitin is a complex of large molecules that weave through the extracellular matrix of cartilage. Its strong negative charge attracts and holds water in cartilage like a sponge. Chondroitin helps joints by:

  1. Maintaining hydration for lubricated, shock-absorbing cartilage performance;
  2. Supporting healthy collagen production, a key building block of healthy joints;
  3. Promoting chondrocyte cells that regulate cartilage growth and repair

Performance Lab® Flex Mythocondro® boosts chondroitin bioavailability by 43% for superior joint support at a lower dosage. Mythocondro® is also the only vegetarian chondroitin; other forms have animal origins including pork byproducts, shark cartilage and bovine connective tissue.

Mythocondro® Chondroitin Sulfate

Chondroitin Sulfate - Chondroitin Sulfate acts as a shock-absorber, supporting healthy growth and repair.

OptiMSM® Methylsulfonylmethane (MSM), 100 mg

Organic sulfur Methylsulfonylmethane (MSM) is a key structural nutrient needed to form and maintain collagen, glucosamine, chondroitin and other proteins that comprise cartilage and connective tissues.

Performance Lab® Flex OptiMSM® is the purest and only GRAS-designated MSM, made in the USA with a proprietary multi-stage distillation process that yields superior purity, quality and consistency.

Methylsulfonylmethane

Methylsulfonylmethane - Methylsulfonylmethane slows the breakdown of cartilage, protecting against bone-grinding wear and tear.

NutriGenesis® Strontium, 300 mcg

Strong bones support joint heath and flexibility. A calcium-like trace mineral, strontium migrates to the skeletal system where it is incorporated into bone matrix crystals. Here, strontium works by:

  1. Stimulating the production of osteoblasts (bone-building cells)
  2. Inhibiting the activity of osteoclasts (bone-breakdown cells)

Strontium’s dual activities may be ideal for joint health because they combine to help preserve existing bone integrity, especially the subchondral bone that forms a smooth, strong surface under cartilage.

Flex NutriGenesis® Strontium is lab-grown on cultures to produce a clean and bioavailable elemental mineral supplement for superior bone strength support.

Take Performance Lab® Flex to soothe joint aches, bounce back faster and maintain healthy flexibility over time.

Upgrade Yourself®

Performance Lab® Flex helps joints and connective tissues to perform their best in motion and recover comfortably at rest. Upgrade your flexibility and excel physically at everything you do.
