1. Cissus Quadrangularis


Cissus quadrangularis is a vining plant in the grape family found in India which has been used for medicinal purposes for millennia in traditional Ayurvedic medicine. While the natural remedy has been applied to a wide variety of illnesses, Cissus quadrangularis is best known for its uses on bone and in pain control.(1) Studies have shown that Cissus quadrangularis reduces fracture healing time(2,3) and also prevents experimentally-induced osteoporosis.(4,5) These effects are thought to be due to the product’s ability to enhance the proliferation, differentiation, and mineralization of human bone-creating cells (human osteoblast-like SaOS-2 cells),(6) presumably by augmenting local growth factors.(7) Multiple in vitro and animal studies have suggested extracts of Cissus quadrangularis may protect the types of cells found in the stomach and from the damage that common pain killers (NSAIDs) cause.(8-12) This property is thought to be related to an immunomodulating effect and antioxidant activity. Animal research suggests Cissus quadrangularis possesses pain relieving, anti-inflammatory properties.(13) NewJoint contains optimum levels of highly purified cissus quadrangularis extract for maximum strength.

2. Avocado Unsaponifiables


Avocado unsaponifiables, which are the highly oily extracts of avocado oils, have gained recent research interest in the field of osteoarthritis and joint health. Popularly recommended by physicians in Europe, this natural product appears to help patients manage osteoarthritis symptoms, with some patients finding they need less NSAID pain killers to for their osteoarthritis related pain when taking avocado unsaponifiables.(1-5) One proposed mechanism of this joint comforting effect is that avocado unsaponifiables are able to preserve joint cartilage by reducing the damage caused by inflammation.(6) The extract may also work by up-regulating glycosaminoglycan and collagen synthesis, which are important in joint structure and integrity.(7) Moreover, avocado unsaponifiables may reduce pain by blocking COX-2 expression and prostaglandin E2 production.(8)  NewJoint uses ultra high quality Avocado unsaponifiables in effective dosage quantities for maximum benefit.

3. Cholecalciferol 


Cholecalciferol, or vitamin D3, is critically important in bone metabolism (formation and remodeling). Cholecalciferol is essential for the proper absorption of calcium from the diet. When cholecalciferol levels are low, it may lead to osteopenia and osteoporosis.(1) Of the various ways to supplement vitamin D, cholecalciferol is preferred.(2) The prevalence of low vitamin D has increased recently and many people may have a deficiency and not realize it which is called a subclinical vitamin D deficiency.(3) This can lead to increased bone fracture risk as well as muscle weakness.(3) For osteoporosis treatment cholecalciferol supplementation alone may be sufficient to prevent falls and fractures.(6) Research suggests cholecalciferol may enhance bone mineral density in individuals with osteoarthrtitis.(7) The International Osteoporosis Foundation recommends vitamin D blood levels of 30 ng/ml for adults over age 60.8 The Harvard School of Public Health states: “Taking a vitamin D supplement of 800 to 1,000 IU per day will help people, on average, achieve adequate blood levels of vitamin D (30 ng/mL). These vitamin D amounts are safe”.(9) NewJoint provides 1000IU of bioidentical cholecalciferol per day to support optimal joint health.
