The anti-ageing benefits of Krill Oil

The anti-ageing benefits of Krill Oil | Mr Vitamins
rp_krill.jpgThese tiny crustacean fish could hold the key to so many health benefits  Krill (Euphausia superba) are small, red-coloured crustaceans, similar to shrimp, that flourish in the depths of the cold waters of the Antarctic Ocean. (1) They are rich in phospholipids which carry long-chain polyunsaturated Omega-3 fatty acids, mainly EPA and DHA. Krill also contain the antioxidants vitamins A and E, and Astaxanthin. (2,3) The EPA and DHA fatty acid profile of Krill oil resembles that of shrimp and fish, but with only 63% of the EPA/DHA content of fish oil, suggesting greater absorption. The DHA content of Krill oil is similar to that of oily fish, but the EPA content is higher. The EPA/DHA fatty acids in Krill are 1.6 times more absorbable than the EPA/DHA in fish oil. (4)

Phospholipids key to better absorption and health benefits

The health benefits of Krill oil are thought to be a result of its phospholipids being bound to, and carrying, high Omega-3 (EPA and DHA) content. Most of the fatty acids in fish are incorporated into triglycerides, whereas 30-60% of the fatty acids in Krill are incorporated into phospholipids. This had led researchers to hypothesise that phospholipids help to improve the bioavailability of EPA and DHA. (4,5) Phospholipids are structural components of human cell membranes. They are water-soluble, have better bioavailability and are more efficiently incorporated into cell membranes than triglyceride or free fatty acid forms of omega-3. (6,7)

Astaxanthin and anti-ageing

When measuring the oxygen radical absorbance capacity (ORAC), which shows the ability to block free radicals, Krill oil is 48 times more effective than fish oil and 34 times more effective than coenzyme Q10. (1) The antioxidant activity of Krill oil is attributed to its Astaxanthin content; a powerful antioxidant of the carotenoid family. (8) Clinical studies confirm that Astaxanthin has significant effects on:
  • lipid peroxidation (oxidative damage to lipids)
  • inflammation
  • obesity-induced oxidative stress
  • functional dyspepsia and
  • male infertility
It is reported to improve:
  • lipid metabolism,
  • reducing triglyceride and total cholesterol
  • increasing HDL cholesterol (9)
Astaxanthin has been shown to affect the signs of skin ageing by improving:
  • skin wrinkle (‘crow’s feet’)
  • age spots
  • elasticity
  • texture
  • moisture content (8)

Cholesterol and heart health improved with Krill Oil

Omega-3 has been reported to decrease the risk of cardiovascular disease through mechanisms of reducing inflammation, blood pressure, plaque accumulation and cholesterol. (10) Supplementing with Krill oil has shown to be effective at managing cholesterol; reducing total cholesterol, LDLs and triglycerides while increasing levels of HDLs. (2,11) A three month clinical trial involving 120 patients found that a daily dose of 1-3g of Krill oil was supportive in hyperlipidaemia (high levels of fats in the blood), with 500mg Krill oil being effective for long-term regulation of blood lipids. (2) At the end of the 90 days, those taking Krill oil were shown to have reduced LDLs by 32-39% and triglycerides by 11-26.5%, while having increased HDLs by 44-59%. 2,3 Recent research suggests Krill oil may be more effective at lowering cholesterol than fish oil. (1)

Krill Oil for metabolic syndrome and weight management

It appears that an increased intake of Omega-3 Krill oil can help support weight loss. (11) A diet high in Krill oil (EPA, DHA and phospholipids) provides:
  • changes in membrane fatty acid composition(10)
  • decreases blood sugar(1) or
  • preserves glucose homeostasis and reverses
  • fatty liver
  • fat-cell enlargement and
  • inflammation of white adipose tissue
supporting their use in improving and treating obesity-associated metabolic disorders. (7)

Arthritis relief with Omega-3

One of the many benefits of Omega-3 found in clinical trials is its anti-inflammatory action in the body. Krill oil has also been found to exhibit positive effects on the joints in arthritis, reducing pain by 30% and stiffness by 20% within 7-14 days. (12,13)

Relief for PMS and dysmenorrhea (painful periods)

Adequate levels of Omega-3 have been shown to reduce symptoms of premenstrual syndrome such as
  • bloating
  • weight gain
  • abdominal pain
  • depression
  • irritability and
  • feeling overwhelmed
Krill oil also reduces dysmenorrhoea and the use of analgesics in menstruating women. (14)

Krill Oil for Brain health

DHA is an important component of the brain and necessary for brain cells to communicate. Studies show Krill oil improves focus and concentration in those with ADHD (15) and may offer anti-inflammatory assistance in stroke. (16) The amount of Omega-3 in the brain tends to decrease with age, decreasing membrane fluidity and cell communication, therefore impairing memory. Krill oil, and its phospholipids and fatty acids, play an important role in elderly brain function as well as during pregnancy and infancy where DHA is essential for neurological development. (5) Krill are essential organisms in the Antarctic ecosystem and are food for whales, seals and penguins. Therefore, it is important that Krill oil is obtained from an environmentally sustainable source.

Krill Oil Supplement Study

Mr Vitamins is proud to announce an Omega 3 (Krill Oil) Supplement Study jointly sponsored by the University of Western Sydney, The National Institute of Complementary Medicine and Bioceuticals. Mr Vitamins Clinic and our qualified naturopaths have been chosen to lead this important study to determine the effectiveness of a newly formulated Omega 3 supplement (Krill Oil) to improve omega 3 levels. Your participation is a much valued contribution to this important work. Find out more, and enquire about being part of this trial here:
