If you are making your own fish oil review, there are a couple of questions you need to ask. Some of them are as follows:
How do I make sure that I get quality fish oil and enjoy all of its health benefits?
When choosing fish oil supplements, you should only choose high purity, molecularly distilled pharmaceutical grade fish oil. You should concern yourself with choosing a fish oil supplement that is 101% safe and effective. Not all brands in the market are, so choose wisely.
This may sound surprising but impure fish oils can contain toxins which may bring you more harm than good. I am talking about mercury, PBAs and other toxic chemicals which are sadly present in the oceans today due to environmental contamination. Fish oils have to be purified to remove them. If the purification method is not efficient, you will end up ingesting these toxins as well.
As you know, pharmaceutical grade supplements are those that pass industry standards such as international fish oil standards (IFOS) to be pure and safe. However, when doing a fish oil reviews, note that there is officially no such thing as pharmaceutical grade fish oil. The USP has not drawn up standards for fish oil. Instead, there are private commercial standards such as the IFOS and CRN. Fish oil manufacturers usually have independent standards and certification method to assess their level of purity. Thus, when you choose fish oils, make sure you check how tough their standards are and compare accordingly.
Before you purchase fish oil, you should take a look at its Certificate of Analysis. Reputable fish oil manufacturers will readily provide you their product's CoA. This is very important in your fish oil review. It should contain information regarding the quality and purity of the fish oil supplement. It should describe how much fatty acid it contains, what components are included (and their amounts), as well as the amounts of heavy metals it contains. For safety, you have to make sure that the heavy metal content is fit for human consumption.
Contrary to what some manufacturers claim, there is actually no need for enteric coating for fish oil. There has been no evidence which proves the benefit of enteric coating in fish oil or studies proving long term safety. Some companies use them simply because it can mask rancidity. More reputable fish oil companies use water based aqueous coat on their tablets as it is proven to be 100% safe (although expensive).
Most fish oil supplements today come in triglyceride DHA form. However, before the body can use it up, the triglyceride form needs to be converted into ester. Thus for maximum absorbability, DHA ester should be a better form.
The recommended dose for fish oils generally depend on the brand. Reputable brands have concentrated amounts of fish oils in their pills so 2-4 soft gels per day should be enough. However, other cheap brands may recommend taking more, since the amount of pure fish oil per tablet may be compromised.
I hope these guide questions will be able to help you do your fish oil review and choose only the best.
