Primal Flex Ingredients


Magnesium is a mineral with many health benefits, and its effect on joint wellness and osteoarthritis has been researched in many studies. Findings indicate magnesium is an anti-inflammatory agent that reduces the C-reactive protein (CRP) marker that can cause inflammation.

An NIH study by A. Shmagel and his colleagues in 2018 also confirmed lower magnesium intake is associated with worse pain and function in the knee.

Vitamin C

Vitamin C is an essential substance with significant roles in the human body, including joints, bone, skin health, and collagen production.

Some studies show the effect of vitamin C supplementation on osteoarthritis (degenerative joint disease) treatment or prevention. Vitamin C can also aid in reducing the knee’s arthritic symptoms, joint pain, and swelling.

Biocell Collagen

Biocell Collagen (aka Biocell® Hydrolyzed Type II Collagen) is a mixture of collagen Type II, hyaluronic acid, and chondroitin sulfate. These are vital ingredients for your joints that can help lubricate the regions of your knees and bones, avoid osteoarthritis, and eliminate exhausting joint pain.

Hector L. Lopez in his 2015 research evaluated the effects of Biocell Collagen cartilage extract on connective tissue support and functional recovery and indicated more robust muscular recovery. However, the official survey of BioCell Collagen®, hydrolyzed chicken sternal cartilage extract, worked on the improved blood microcirculation and anti-aging aspects.


Withania somnifera, aka Ashwagandha, is an Indian Ayurvedic herbal medicine used for various diseases. Modern science has considered this ingredient as an adaptogenic/anti-stress remedy and has researched its effectiveness.

Ashwagandha is an anti-arthritic and anti-inflammatory herb, useful in clinical cases of Rheumatoid and Osteoarthritis. A randomized, controlled study by G.S.H. Ramakanth in 2016 showed the efficacy of Ashwagandha extracts in reducing knee joint pain.


Astaxanthin (Ast), a bioactive compound with natural resources, is an antioxidant & carotenoid pigment found in sea creatures such as shrimp and microalgae. Ast has been researched as a degenerative joint disease potential therapeutic supplement.
