What is ZanthoSyn?

There is a lot of need for good anti-inflammatory products these days. It seems like the list of uses and health benefits that anti-inflammatories carry with them are growing by the day.

For instance, if you are suffering from joint pain, a quality anti-inflammatory may help.


There is also some evidence to suggest that they can support cardiovascular health as well. Today we will be looking at a supplement that claims to be a powerful anti-inflammatory. It is called ZanthoSyn.

Whereas many anti-inflammatory supplements get their potency and ability from substances like turmeric and curcumin, ZanthoSyn distinguishes itself by using an ingredient called Astaxanthin, a naturally occurring substance found in many marine creatures.

ZanthoSyn is supposed to be able to reduce joint inflammation and promote liver health. This is an oral supplement that comes in capsule form and is made available directly from the manufacturer.

Who is the Manufacturer of ZanthoSyn?

ZanthoSyn is made by a company that is based in Hawaii called Cardax. The company claims that it works closely with the healthcare community in order to provide potent anti-inflammatory products for the overall health of consumers.

The company was established back in 2006 and center their main product, ZanthoSyn, around the efficacy of the ingredient Astaxanthin.

Cardax states that ZanthoSyn can help many areas of a user’s health because their form of synthetically-derived Astaxanthin is much purer than naturally-sourced Astaxanthin and that it absorbs in the body at a higher rate.

How Does ZanthoSyn Work?

The function of ZanthoSyn depends greatly on Astaxanthin as an anti-inflammatory agent. Astaxanthin has been shown in some studies to have certain health benefits including improved cardiovascular health[1].

This ingredient has also been linked with a decrease in inflammation of many forms including cardio inflammation.

ZanthoSyn moves throughout the body when ingested and delivers Astaxanthin to various joints and organs.

One way it may work for joints is to decrease inflammation, and therefore lower pain levels, and keep them in better shape overall.

ZanthoSyn Ingredients – Are They Safe & Effective?

There are only a handful of active ingredients in ZanthoSyn. As stated earlier in this review, the joint pain relief product relies heavily on one of the main active ingredients, Astaxanthin.

The other ingredients are added for antioxidant support or to make the capsule itself.

  • Astaxanthin – Astaxanthin is a pigment that is found in various kinds of marine life. It is said to have useful anti-inflammatory properties and that is how it is used in ZanthoSyn. The form of Astaxanthin in ZanthoSyn is synthesized because, according to the manufacturer, synthesis allows for higher purity and consistency.
  • Glucose Corn Syrup – This ingredient was most likely added to the ZanthoSyn formula for its ability to help items like food, and in this case capsules, maintain their consistency[2] and also possibly as a preservative substance.
  • DL-Alpha Tocopherol – This ingredient is a synthesized version of vitamin E. It is a type of tocopherol and can be found naturally in plant oils.

What are the Advantages of ZanthoSyn?

  • This product may help to reduce joint pain that is brought on by inflammation.
  • There is also evidence to suggest that the ingredients in ZanthoSyn may help to improve heart health.

    This supplement was recommended to me by a Physician who was treating me for my condition. He uses after he completes his daily runs or after he participates in one those marathon runs.
