SynerFlex Reviewed: Get the Facts about SynerFlex

Editor Review: 3.5 / 5.0 editor's review

SynerFlex is a product that is manufactured by North Star Nutritionals, and it seems like there is a good amount of information provided on the website. However, the tone of the website seems quite gimmicky, and is laid out like a personal letter to the customer. The site does offer contact information and a 60-day guarantee on its product, which is a good benefit to make up for the tone of the content. SynerFlex can be ordered securely through the company website, which is the only way that it can be purchased. This supplement costs about $40 for a single month’s supply, and customers can sign up for autoshipping to get discounts on their orders.


SynerFlex uses the active ingredient Hyal-joint, which is a blend of hyaluronic acid, hops extracts, and boswellia, a known pain inhibitor. There is no full ingredient list, but there is plenty of information provided about the main formula used in this supplement. It does state on the website that clinical studies have been done, but the site lists no actual published studies or proof of results in regard to these supposed studies. SynerFlex claims to reduce pain and inflammation while also repairing joints with its proprietary formula.

SynerFlex does offer secure ordering with a guarantee on customer satisfaction, and there are options for discounts depending on how you order and how much you order. The active ingredients are listed and explained on the website. Also, company information is given and there are special deals for customers who sign up for auto-shipping. However, the product does not contain known joint supplement ingredients chondroitin and glucosamine. There are also no clinical studies and the site lacks a full list of ingredients. The tone of the website is not at all professional and seems ‘too good to be true’.

The bottom line is that the ingredients of SynerFlex might be effective at helping with joint lubrication, but they do not rebuild the joints like other supplements. Also, the lack of clinical results and the gimmicky nature of the website are questionable.

It is never too early or too late to begin taking a joint supplement and making the practices outlined above part of your lifestyle. Using a good quality product will help repair existing tissue damage and also provide building blocks for stronger joints that are less susceptible to future degeneration. Reducing and relieving joint pain using a combination of supplements and lifestyle changes can improve overall mobility and help the joints function optimally. Incorporating the right essential ingredients should be the goal of anyone hoping to improve their overall quality of life.
