Krill oil is that potentially healthy fatty acid you can get as a supplement. Coming from a tiny crustacean similar to shrimp or prawn, it makes up the largest biomass on Earth, along with plankton.
A true rising star in nutrition by combining antioxidants with Omega 3s, its ability to fight oxidative stress turns this little reddish sea creature into a real powerhouse that’ll help you tackle daily life. Ready to dive into the 9 benefits and properties of Krill oil for your health?

1. Reduces cholesterol
After just 12 weeks of taking Krill oil, you’ll notice cholesterol generally drops by 13%, triglycerides by 11%, LDL by 32%, and HDL goes up by over 44%. Pretty impressive, right?
Specifically, one study shows that Krill oil lowers LDL or “bad” cholesterol. In it, a daily dose of 1,0 to 1,5 g of Krill oil had more noticeable effects reducing LDL and triglyceride levels than a dose two or three times higher of another fish oil (3 g daily). At higher doses, it also lowers blood triglycerides, something no other fish oil manages for your health.

2. Eases premenstrual syndrome symptoms
The first major clinical study on this substance looked at its effects on premenstrual syndrome, or PMS.
The 2002 study, conducted over three months by researchers in Quebec on using Krill oil to relieve PMS symptoms, concluded that taking this substance drastically reduces the physical and emotional symptoms linked to PMS and painful menstruation known as dysmenorrhea.
Here are the main benefits of Krill oil for PMS!
- Reduces abdominal pain and uterine cramps by 33%
- Decreases menstrual irritability by 47%
- Lowers blood pressure by 49%
- Reduces weight gain by 30%
- Decreases fluid retention by 37%
- Reduces breast tenderness related to PMS by 42%
- Relieves headaches, body aches, and joint pain
- Improves mood swings, cravings, and whims
- Eases nausea, fatigue, and bloating
- Helps prevent anxiety and stress linked to menstruation
3. Relieves joint pain
Krill oil shows its power in joint health, producing effects on inflammation (C-reactive protein, CRP). Taking just 300 g daily reduces blood levels of C-reactive protein, according to a study.
Also, this oil is a strong aid for joint pain. This comes from carefully controlled tests analyzing its effects on patients with osteoarthritis, rheumatoid arthritis, or elevated blood levels of C-reactive protein (CRP), a molecule produced by the liver in response to inflammation. The results were very encouraging for health.
After only 7 days of taking Krill oil, the effects on joints were:
- Pain reduction by 24%
- Flexibility improvement by 16%
- Stiffness reduction by 22%

4. Supports cardiovascular health
And what about the close link between Krill oil, that Omega 3 source, and cardiovascular health? Just like fish oil, its lipid profile supports heart and blood circulation health.
Why is Krill oil good for the heart? Because researchers have concluded its benefits come from its unique molecular structure.
Its rich content of phospholipids and antioxidants (especially astaxanthin) explains its powerful effect on regulating blood lipids.
Its secret lies in an excellent combo of useful substances with “superior effects” in lowering the risk of cardiovascular diseases.
5. Improves skin appearance
The powerful antioxidants in Krill oil could be the rejuvenating formula you’ve been looking for. These antioxidants protect your skin from damage and inflammation caused by ultraviolet rays. And here’s the exciting news: for the first time ever, there’s a capsule you can take orally to protect yourself from the sun.
Other possible health benefits from these tiny semi-transparent creatures, which feed whales, seals, penguins, seabirds, fish, and squids, come from studies on how Krill oil acts on eczema and psoriasis cases.
Finally, it also improves hair and nails, helping you get shinier hair, less hair loss, and stronger nails.

6. Boosts energy
In a quality of life survey, 51% of participants reported feeling more energy, less sluggish while taking this oil.
Athletes also confirmed better endurance and higher performance after taking it. Researchers think this is due to the high choline content (a key component of acetylcholine, a brain chemical) combined with Omega 3 fatty acids.
7. Promotes concentration and attention
Studies with kids with dyslexia, ADHD, or autism back this up. Their parents noticed a significant improvement in their children’s concentration and attention levels after starting Krill oil.
Normal cognitive function is supported by the phospholipids found in Krill. They boost abilities like memory, mental sharpness, and attention, improving behavior and lifting mood.
8. Eases hay fever symptoms
The anti-inflammatory properties of Krill oil reduce symptoms of rhinitis, runny nose, eye pain, and wheezing linked to immune system responses to pollen and other microscopic allergens.

9. Reduces autoimmune diseases
A study published by the American College of Nutrition in December 2002 reported that Omega 3 fatty acids from fish oil can bring considerable improvements to patients diagnosed with inflammatory and autoimmune diseases.
Currently, tests are underway to determine Krill oil’s effects for treating rheumatoid arthritis, Crohn’s disease, lupus, and multiple sclerosis.
Did you know Krill oil carries such great news for your health? A little “treasure” from the sea in supplement form (more info), with an impressive Omega 3 content and multiple benefits and properties backed by science. Mind-blowing, right? No wonder, this crustacean comes straight from Antarctica!
