## Overview

Core FLEX is a scientifically formulated joint supplement combining 11 clinically studied ingredients designed to maintain strong tendons, ligaments, and cartilage.

## Description

TOTAL JOINT CARE: Core FLEX is an ultra-potent combination of 11 clinical ingredients, crafted to ensure the maintenance of strong and healthy tendons and ligaments. Best of all, its all-in-one blend combines the efficacy of single ingredient products, with the synergy of an entire joint product lineup. ATHLETIC STRESS SUPPORT: Just like a vehicle, our bodies are exposed to the constant wear and tear of demanding daily use, a fact especially true of athletes. As we put more and more weight on the bar, run faster and further, and push our bodies to the limit, our joints, tendons, and ligaments require regular maintenance to keep them in optimal health. JOINT FUNCTION & STRENGTH: Core FLEX combines Cissus quadrangularis, shown to improve joint mobility and strength, with Boswellia, an extract that supports tendon health and reduces cartilage breakdown, helping your joints perform and recover under daily stress and heavy training. RECOVERY & RESILIENCE: With Glucosamine to cushion joints, Chondroitin to support cartilage integrity and repair, and antioxidant-rich turmeric and black cherry to combat everyday wear, Core FLEX helps speed recovery, protect connective tissue, and keep you moving strong. THE CRUSH IT LIFESTYLE: Core Nutritionals is committed to transparency and quality, with all products manufactured in the U.S. in cGMP facilities and backed by rigorous testing. Our mission is built on the CRUSH IT mentality— pursuing excellence, integrity, and helping others achieve their best both in and out of the gym.

Review: Flex - I used this product for my back and it works great.
Review: The best joint product I have ever taken - I have been a huge fan of Core Nutritionals for nearly a decade, as they have been a pioneer in scientifically formulated products consistently churning out top notch products. I have battled knee joint pain for many years, but after switching to Core Flex after trying countless others, my knees feel better than they have in quite some time. It will be very hard for me to take another joint supplement ever again.
