Shark liver oil is an extract prepared from the livers of sharks. The oil has been used for centuries as both a food and as a remedy for a number of common ailments. At present, the amount of research into the efficacy of the oil is somewhat limited, although there is data available on the basic nutritional content and some anecdotal evidence regarding the health benefits derived from consuming the product.

In terms of nutrients, shark liver oil is found to have significant amounts of Vitamins A and D, as well as being a good source of omega-3 fatty acids. The oil also has a high content of alkylglycerols accompanied by fatty alcohols and glycerol ethers.

Despite the long history of the oil as a folk remedy for everything from sore muscles to wound healing, there are some concerns about the frequent use of the product. Side effects such as diarrhea and nausea have been reported, especially when frequent use of some type of the supplement is used daily. A few studies indicate that excess consumption could lead to an unhealthy increase in triglyceride levels. Some users have also noted cramping and a generally upset stomach.

Today it is possible to purchase shark liver oil at many health food stores. Along with small bottles of processed oil, it is also possible to obtain softgels as well as shark liver capsules. Many people prefer the softgels and capsules due to the somewhat pungent taste of the product.

While there is no current evidence that the oil has a negative interaction with prescription medication, it is important to report its usage to the attending physician. Should any side effects become apparent while using the oil in conjunction with any prescription medication, it is a good idea to cease use immediately and contact your doctor.

As far as the side effects of shark liver oil are concerned, this may be in reference to using it in excess. When it comes to ailments and medications, the stronger they are, the less they should be used, and the smaller the dosages should be. Have you ever had some of those medications that had many side affects if you overdosed? Well, that seems to be the case here, except in this case, it's even more so.

In a previous article, it mentioned that sharks are at the top of the food chain. However, that they have been in reference to their natural habitat. Humans on the other hand, are at the top of the food chain, period. Whether we're using animals for their fur, taking them out of their natural habitat, or killing sharks and using their liver oil for remedy purposes, no animal is safe from us.
