What is SynerFlex?

SynerFlex has a lot of antioxidants in it, which are supposed to help repair joint degeneration. Anti-inflammatory compounds, which are abundant in them, can help reduce swelling and joint pain. The tone of the product website is gimmicky, written in the form of a ‘personal’ letter to the customer which detracts greatly from the actual brand. However, the North Star Nutritionals site, on the whole, is informative, full company contact details are given and they do offer a money-back guarantee on all their products.

*All individuals are unique. Your results can and will vary.

The main active ingredient in SynerFlex is Hyal-joint, a formula that consists of Hyaluronic acid, a substance that increases the production of protective synovial fluid in the joint.

Also, key in the formula is Hops extract an anti-oxidant, and anti-inflammatory, and concentrated Boswellia. This is a substance that aids in inhibiting pain-causing Cox-2 in the body, also reducing swelling and allowing healing to occur.

SynerFlex Ingredients – Are They Safe & Effective?

Boswellia Serrata

– This tree is indigenous to India. Anti-inflammatory compounds, which are abundant in it, help lessen arthritic symptoms.

According to a study in the journal Phytomedicine, this tree is particularly good at treating the signs and symptoms of knee arthritis[1].

Hops Flower Extract

– There is evidence that the isohumulones in this flower help lessen[2] arthritic symptoms in both animals and people, according to a PharmaNutrition article.


– This is a blend of hyaluronic acid, collagen, and glucosamine that is proprietary. Hydration is drawn into the region between the joints by hyaluronic acid, keeping it supple and pliable[3]. Recent developments in hyaluronic acid-based osteoarthritis treatment were explored in a review published in Clinical Translational Medicine.

SynerFlex – Customer Reviews

  • “My range of motion has improved, and my joint pain has decreased. With my purchase of SynerFlex, I’m quite pleased. But quite expensive product” ~ Jordan

SynerFlex Review – The Conclusion

Even if SynerFlex were a reliable joint pain relief treatment, the way it is presented would likely deter many prospective consumers. Additionally, while the large amounts of Hyaluronic acid in the formula may provide plenty of lubrication, there is no evidence to show that SynerFlex can successfully restore damaged cartilage.

Bones are connected by joints, which allow us to move with ease. Joint damage can cause pain preventing you from doing the things you once loved. Many conditions lead to joint pain from aging to an untreated sports injury. A quality joint product may help repair existing tissue damage and also promote stronger joints, less susceptible to future degeneration.

Below you’ll find some of the most effective joint pain supplements on the market today, in our opinion.
