The Omega 3 fatty acids found in krill oil have been shown to support healthy blood pressure and heart rhythm, plus long-term heart health. For optimizing healthy cholesterol and decreasing triglycerides, research suggests krill oil is the way to go. A 12-week study published in the journal Lipid Technology looked at 120 people with high cholesterol and high triglycerides and found those taking 1.5 grams of krill oil per day had significantly healthier blood pressure. The krill oil group also saw measured benefits, with improvements upon cholesterol and triglycerides levels. Still not convinced that krill oil is good for your heart? Krill oil offers these additional benefits:
- No Fishy Burp Back: Because omega-3s from phospholipids are water-soluble, they don’t pool on top of the stomach — prompting reflux and fishy aftertaste — like some fish oil supplements.
- More Efficient: Omega-3s from krill are used more efficiently in the body than some other sources. Another study found that when 48 people took 100 mg of EPA/DHA for 112 days, those getting it from krill oil saw their omega-3 index (a measure of levels in red blood cells) jump 67 percent, 2.5 times as much as those getting it from other sources. Yet another study looked at 113 people over seven weeks and found that those taking krill oil could take 543 mg of omega-3 DHA and EPA from krill oil and get a comparable improvement in blood levels as those taking 864 mg of DHA/EPA from fish oil.
- Antioxidant Astaxanthin: Krill is loaded with the powerful antioxidant, astaxanthin. Shown to be 300 times more potent than vitamins E and A, astaxanthin helps protect cell membranes from free-radical damage and also serves as a natural preservative in krill oil, keeping it fresher longer.
- Contains Choline: Choline is a key building block for the neurotransmitter acetylcholine, which helps support memory and communication between brain cells and may reduce the risk of breast and colorectal cancer. Because choline is typically found in beef, liver, and chicken, those who don’t consume a lot of meat are often deficient.
- Minimal Omega-6: While fish oil tends to contain some omega-6 fats (pro-inflammatory fats which, in excess can counteract the benefits of omega-3s), krill oil contains almost none.
