Does CELL-FX® Contain Any Ingredients That Actually Work?

Joint health products are among the top 3 types of dietary supplement products in terms of sales.  Other popular dietary supplements include both cold remedies as well as probiotics.  Many of the top-selling dietary supplements which are designed for promoting joint health contain chondroitin sulfate and glucosamine sulfate.

What Ingredients are in CELL-FX®?

“CELL-FX® is a proprietary powdered natural product derived from shark cartilage. Each capsule contains 400 mg of a standardized shark cartilage extract comprised of chondroitin sulphate. Non-medicinal ingredients include: gelatin, microcrystalline cellulose and magnesium stearate. The CELL-FX extract is 100% water soluble and is standardized to ensure consistency from batch to batch.”

Does Chondroitin Sulfate Work?

To answer this question, let’s take a look at the results of a meta-analysis recently published in the esteemed medical journal, Annals of Internal Medicine ( Reichenbach S et al, 2007).

“Large-scale, methodologically sound trials indicate that the symptomatic benefit of chondroitin is minimal or nonexistent. Use of chondroitin in routine clinical practice should therefore be discouraged (Reichenbach et al, 2007).”

According to the results of this recent publication in the medical journal, Annals of Internal Medicine, people who take dietary supplements which include chondroitin sulfate may be wasting their time and their money on these products.

Chondroitin Sulfate is found in many of the blank Glucosamine/MSM/Chondroitin Sulfate product formulations which are often found in both drug and grocery stores. It is also the sole active ingredient in Cell FX from Afexa Life Sciences, formerly CV Technologies.
