What is Krill Oil,How does it work, Benefits, Side Effects | The Ultimate Beginner's Guide - Health and Fitness City

What is Krill Oil?

Krill oil is oil from a tiny, shrimp-like animal. Baleen whales, mantas, and whale sharks eat primarily krill. In Norwegian, the word "krill" means
"whale food." People extract the oil from krill, place it in capsules, and
use it for medicine. Some brand name krill oil products indicate that they use Antarctic krill. This usually refers to the species of krill called Euphausia superba.

Krill oil is most commonly used for heart disease, high levels of certain blood fats (triglycerides), and high cholesterol, but there is limited scientific research to support these uses.

How does it work?

Krill oil contains fatty acids similar to fish oil. These fats are thought to be beneficial fats that decrease swelling, lower cholesterol, and make blood platelets less sticky. When blood platelets are less sticky they are less likely to form clots.

Benefits of Krill Oil

1. Aging skin. Early research suggests that taking capsules containing krill oil, zinc, vitamin D, sea buckthorn berry oil, cacao bean extract, hyaluronic acid, and red clover isoflavones 780 mg three times daily along with applying tazarotene cream 0.1% nightly for about 12 weeks improves wrinkles, moisture, and elasticity in aging skin compared to treatment with tazarotene cream alone. It is not clear if these benefits were due to krill oil or other ingredients in the supplement.

2. High cholesterol. Developing research shows that taking 1-1.5 grams of a specific krill oil product daily reduces total cholesterol and "bad" low-density lipoprotein (LDL) cholesterol, and increases "good" high-density lipoprotein (HDL) cholesterol in patients with high cholesterol. Higher doses of 2-3 grams daily also appear to significantly reduce levels of triglyceride, another type of blood fat.

3. High triglycerides, a type of blood fat. Taking a specific krill oil product 0.25-2 grams twice daily for 12 weeks appears to lower triglyceride levels in people with high triglyceride levels. However, the change in triglyceride levels varies among patients. The supplement does not appear to improve total cholesterol, "bad" low-density lipoprotein (LDL) cholesterol, or "good" high-density lipoprotein (HDL) cholesterol.

4. Osteoarthritis. Early research shows that taking 300 mg per day of a specific krill oil product reduces pain and stiffness in people with osteoarthritis.

5. Premenstrual syndrome (PMS). Early research shows that taking 2 grams per day of a specific krill oil product might reduce PMS symptoms. Also, taking a specific combination product containing krill oil, B vitamins, soy isoflavones, and rosemary extract daily for 3 months reduces self-reported PMS symptoms. The improvements appear to be greatest for women with more severe symptoms. However, it is unclear if these improvements were due to krill oil or other ingredients in the supplement.

6. Rheumatoid arthritis. Early research shows that taking 300 mg per day of a specific krill oil product reduces pain and stiffness in people with rheumatoid arthritis.

Side Effects of Krill Oil

Krill oil is POSSIBLY SAFE for most adults when used appropriately for a short amount of time (up to three months). The most common side effects of krill oil are stomach-related and similar to those of fish oil. These effects include stomach discomfort, decreased appetite, taste change, heartburn, fishy burps, bloating, gas, diarrhea, and nausea. Taking krill oil by mouth might also cause facial skin to become oilier or to break out. In very rare cases, krill oil might increase blood pressure.

Special Precautions & Warnings:

1. Pregnancy and breast-feeding: Not enough is known about the use of krill oil during pregnancy and breast-feeding. Stay on the safe side and avoid use.

2. Bleeding disorders: Because krill oil can slow blood clotting, there is concern that it might increase the risk of bleeding in people with bleeding disorders. Until more is known, people with such conditions should use krill oil cautiously.

3. Diabetes: Krill oil might lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use krill oil.

4. Obesity: Krill oil might lower how well insulin works in people who are overweight or obese. This might increase the risk of developing diabetes or heart disease.

5. Seafood allergy: Some people who are allergic to seafood might also be allergic to krill oil supplements. There is no reliable information showing how likely people with seafood allergy are to have an allergic reaction to krill oil; however, until more is known, avoid using krill oil or use it cautiously if you have a seafood allergy.
