Krill Oil is a relatively new product on the market, meant to act as an improved substitute for fish oil due to its supposed increased content in Omega 3. The product aims to improve blood circulation, mental and physical well-being and might also reduce cholesterol levels.

Because of its upcoming success, a large number of manufacturers have put their name on this product. Among them, Source Naturals, a company with 20 years’ experience in the natural supplement industry, that has won a series of awards and acknowledgements based on its products and due to its focus on quality.

This product is advertised as a supplement that can basically do no wrong: it helps combat cholesterol, reduces the intensity of menstrual cramps, pre-menstrual syndrome, fights arthritis, improves blood circulation, heart health and the overall mental condition of its consumers. However, please note that this is a relatively new product on the market, so not all of the effects have been proven and the amount of testimonials can be considered unsatisfactory by some.


1) Krill Oil Quick Facts

Krill oil is extracted from a species of crustaceans that reside on the ocean floor. The harvesting of krill began a couple of years ago, and most of the effects of Krill Oil are still being researched.

The nutrients that make Krill oil so effective are the Omega 3 fatty acids, similar to those in fish oil, and astaxanthin, a potent antioxidant.

Omega 3 fatty acids have a wide array of known positive effects, being considered one of the “miracle substances” of our time. They improve blood circulation, mental health, help combat arthritis, help in cardiac arrhythmia, boost the immune system and have even been speculated to help fight cancer.

The full effects of Astaxanthin are still undergoing research, but due to its antioxidant properties it is thought to have beneficial effects in cardiovascular, neurodegenerative, immune and inflammatory conditions. As with Omega 3, this substance is also rumored to have anti-cancer properties.

The evidence of side-effects is considerably low for Krill Oil; that does not exclude the possibility of issues occurring, such as digestion problems or even blood clotting. It is therefore advised to read the label carefully and consulting with your physician before consumption. Caution is advised if suffering from allergy to shellfish.

3) Is Krill Oil Right for You?

Krill Oil comes from the shrimp-like crustaceans, and it is believed to be a very powerful antioxidant due to the presence of Astaxanthin. This can help protect the cells in the body and the mind from free radicals that can damage them.

The primary use of Krill Oil revolves around it supposedly combating cholesterol, reducing level considerably. Studies indicate the possibility this type of supplement to work without any side-effects. Its potency may also interest women because it is claimed it can help with arthritis and pre-menstrual syndrome. There seems to be no end to the list of things Krill Oil is good at. Unfortunately, there’s insufficient information to verify all of them. Few studies have been made in this sense.

The recommended dose of a Krill Oil supplement is going to depend on each user. Therefore it is critical to take a close look at the information found on the label of the product. There are side-effects to Krill Oil, especially if you’re allergic to seafood.

8) Our Verdict on Krill Oil

Krill Oil seems like an all-around positive experience for anyone that suffers from almost anything. However, there is no such thing as a miracle drug, and customers must keep in mind that not all of the product claims have been medically proven or backed up by sufficient testimonials.

While it is true that Omega 3 consumption has been proven to have the effects advertised by this product, the efficiency of Krill Oil as a whole has yet to be medically attested. Unfortunately, Source Natural’s website offers no testimonials regarding the actions of this supplement, although further research reveals that quite a number of people have tried Krill Oil and are satisfied with the results.

Before making a decision regarding purchase, we advise our readers to conduct their own research into the product and consult a doctor if they have any questions or concerns regarding the product.

I began taking krill oil 7 months ago after my physician indicated my cholesterol was too high at 225. After 7 months, my total level is at 210 and my LDL has gone down considerably.
