Krill Oil

  • Heart and Circulatory Health

    High Cholesterol

    In one study of people with high cholesterol or triglycerides, supplementing with krill oil lowered total cholesterol, LDL cholesterol, and triglycerides, and increased HDL-cholesterol.

    In a double-blind study of people with elevated blood levels of cholesterol and triglycerides, supplementing with 1 to 3 grams per day of krill oil from Antarctic krill (a zooplankton crustacean) for three months decreased total and LDL cholesterol levels and increased HDL cholesterol levels. Krill oil was significantly more effective than either a placebo or small amounts of regular fish oil containing 900 mg per day of omega-3 fatty acids.4

    High Triglycerides

    Supplementing with krill oil may decrease triglycerides in people with elevated levels.

    In a double-blind study of people with elevated blood levels of cholesterol and triglycerides, supplementation with 2 to 3 grams per day of krill oil from Antarctic krill (a zooplankton crustacean) for three months decreased levels of triglycerides. However, 1 to 1.5 grams per day was not effective. Krill oil was significantly more effective than either a placebo or small amounts of regular fish oil containing 900 mg per day of omega-3 fatty acids.5
  • Menstrual and PMS Support

    Dysmenorrhea

    Women who took krill oil had improved abdominal pain and reported using fewer pain relievers for menstrual pain than those who took fish oil in one study.
    Dysmenorrhea
    ×
    In a double-blind trial, women with PMS took 2 grams of either krill oil from Antarctic krill (a zooplankton crustacean) or fish oil for one month, followed by two months in which the women took their supplement beginning eight days prior to menstruation and continuing for two days after the start of menstruation. While abdominal pain symptoms were similarly reduced by either oil, those taking krill oil reported using fewer pain relievers for menstrual pain.6

    Premenstrual Syndrome

    Krill oil has been shown in a double-blind trial to be an effective treatment for premenstrual syndrome, including emotional symptoms and breast tenderness.

    Krill oil from Antarctic krill (a zooplankton crustacean) has been shown in a double-blind trial to be an effective treatment for premenstrual syndrome. Krill oil was significantly more effective than similar amounts of regular fish oil in relieving emotional symptoms and breast tenderness related to premenstrual syndrome. The amount of krill oil used in this study was 2 grams per day for the first month. In the second and third months the women took 2 grams per day beginning eight days prior to menstruation and continuing for two days after the start of menstruation.7
  • Women's Health

While abdominal pain symptoms were similarly reduced by either oil, those taking krill oil reported using fewer pain relievers for menstrual pain.8

  • Joint Health

    Osteoarthritis

    In one study, people who took krill oil saw significant reduction in arthritis severity and used less pain-relief medication than those taking placebo.
    Osteoarthritis
    ×
    In a double-blind study, people with high levels of C-reactive protein (CRP), an indicator of systemic inflammation in the body, most of whom also had osteoarthritis, were given 300 mg each morning of krill oil from Antarctic krill (a zooplankton crustacean) or a placebo. After one month those taking krill oil had significantly greater reduction in arthritis severity based on a questionnaire focusing on joint pain, stiffness, and loss of function related to osteoarthritis of the knee and hip. Use of pain-relief medication was also reduced compared to those taking placebo.10
What Are Star Ratings?
×
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
