Experiencing Pre-Menstrual Syndrome (PMS) can be a really debilitating and serious condition.

Signs of depression, mood swings, anger, inability to concentrate are some of the symptoms that can affect some women every month.

There are a variety of ways you can treat PMS symptoms:

  • Non-Steroidal Anti-inflammatory Drugs (NSAIDS) – Drugs such as Advil, Motrin or Naproxen Sodium are used for easing cramping and breast discomfort.
  • Oral Contraceptives – Used to stop ovulation and can help balance hormonal swings.
  • Antidepressants are sometimes prescribed to reducing symptoms such as fatigue, food cravings and sleep problems.

Unfortunately, some of the prescribed methods to treat certain PMS symptoms can cause side effects including diarrhea, insomnia, tremors, headache, depression, nausea, headaches and abdominal pain.

Study on Neptune Krill Oil and PMS shows Improvement in PMS Symptoms:

Quebec, Canada – A study published in the 2003 issue of Alternative Medicine Review look at using Neptune Krill Oil (NKO) to treat PMS and painful menstrual cramps.

What is krill oil? It’s actually a healthy oil extracted from krill, tiny shrimp that thrive in cold ocean waters.

Krill oil is loaded with healthy omega 3 fatty acids, phospholipids and powerful antioxidants.

Past studies have shown the effectiveness of using fish oils on menstrual cramps.

However, scientists believe that krill oil is absorbed better than fish oils and were curious if it would be more effective for treating PMS.

This study looked at 70 patients diagnosed with PMS who took Antarctic Neptune krill oil or fish oils for 3 months.

The researchers measured the amount of pain relief medication used and other diagnostic tests to check the effectiveness of krill oil compared to fish oils.

Researchers noted the following results:

  • Women taking Antarctic Neptune krill oil used less pain relief medication than the fish oil group to treat their symptoms of PMS and dysmenorrhea.

  • Researchers concluded that Neptune krill oil significantly reduces dysmenorrhea and the emotional symptoms of premenstrual syndrome.

  • It was also found that Neptune krill oil was more effective than fish oils for the complete management of premenstrual symptoms.

Another study looking at Omega-3 DHA and EPA for Cognition, Behavior and Mood found Antarctic krill oil omega-3 phospholipids outperformed fish oils for treating premenstrual syndrome and dysmenorrhea.


Research studies appear to indicate that krill oil’s ingredients may provide the following health benefits:

  • Supports cardio-vascular health

  • May help support healthy blood sugar levels

  • Encourages optimal reproductive cycles

  • Bolsters healthy joints

  • Benefits mental health and immune system function
