Performance Lab Flex Ingredients

Boswellia Serrata, 100mg
Boswellia Serrata has been used in religious and cultural ceremonies for hundreds of years. It comes from a tree that grows in India, Northern Africa, and the Middle East. Resin is sourced from the tree then stored for removal of the oil. It has anti-inflammatory properties, and people have been using it for centuries to treat various chronic inflammatory diseases such as joint pain and swelling. In one of our NuviaLab Flex Reviews article, we have emphasized the benefits associated with incorporating Boswellia into your routine.
According to the US National Library of Medicine, [2] it’s becoming more popular as an added ingredient for treating a variety of disorders, including some types of cancers.
Boswellia Serrata works by modulating immune responses that help protect and soothe joints. It blocks 5-LOX, the enzyme that causes cartilage to thin as we age. It also limits the MMP enzyme that weakens the connective tissues.

CurcuWIN® Turmeric, 250 mg
Curcumin is a compound located in the toot of the turmeric plant. In the Middle East, people use turmeric and curry as seasonings. A recent study suggests [3] that curcumin significantly inhibits colon tumor sizes in animals. This is due to its anti-inflammatory and antioxidant properties.
BMC, a part of Springer Nature, [4] did a study to see if curcumin effectively treats knee osteoarthritis. The findings are that it is an effective treatment, especially for individuals who don’t tolerate the side effects of non-steroidal anti-inflammatory drugs.

Glucosamine Sulfate 2KCI (from corn), 500mg
Glucosamine is a compound naturally produced in cartilage [5] and is the tissue that cushions joints. The supplement form is either harvested from shellfish shells or made in a lab. Studies show that it may help individuals with mild conditions of osteoarthritis and rheumatoid arthritis.
Glucosamine Sulfate is a protein that forms connective tissues. Chondrocyte cells in the joints assists repair and cause new growth of cartilage. It further increases the joint-lubricating synovial fluid, which helps to improve the range of motion.

Phytodroitin
Phytodroitin is a natural, vegan-friendly alternative to chondroitin found in Performance Lab Flex. It supports joint health by improving shock absorption, aiding in cartilage repair, and boosting collagen production. This plant-based ingredient enhances joint flexibility, reduces pain, and protects cartilage from wear and tear, making it ideal for those seeking ethical, effective joint support.

OptiMSM Methylsulfonylmethane (MSM) 100mg
This critical structural nutrient helps form and maintain collagen, glucosamine, chondroitin, and other proteins that strengthen cartilage and connective tissue.
Numerous studies suggest [7] that MSM has a lot of benefits, including lowering inflammation, relieving joint and musical pain, lowering oxidative stress, and increasing antioxidants. It is considered safe and is approved for safety as little as grams daily can substantially improve the quality of life for individuals who suffer from chronic joint pain.
