Calanus finmarchicus, zooplankton oil.
Calanus oil is a red-colored oil that comes from a type of plankton in the North Seas.
How does it work?
Calanus oil contains omega-3 fatty acids such as docosahexaenoic acid and eicosopentaenoic acid. It also contains a red pigment called astaxanthin which gives the oil a red color. Research in animals shows that calanus oil might help prevent hardening of the arteries. It might also decrease the size of fat cells in animals. But it is not known if calanus oil has any beneficial effects when consumed by humans.
Insufficient Evidence to Rate Effectiveness for...
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
There isn't enough reliable information available to know if calanus oil is safe or what the side effects might be.
The appropriate dose of calanus oil depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for calanus oil. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
