Cosmetic benefits of astaxanthin on humans subjects

Abstract: Two human clinical studies were performed. One was an open-label non-controlled study involving 30 healthy female subjects for 8 weeks. Significant improvements were observed by combining 6 mg per day oral supplementation and 2 ml (78.9 μM solution) per day topical application of astaxanthin. Astaxanthin derived from […]

Astaxanthin in cardiovascular health and disease.

2018-03-22T21:48:11-05:00

Astaxanthin in cardiovascular health and disease. Abstract: Oxidative stress and inflammation are established processes contributing to cardiovascular disease caused by atherosclerosis. However, antioxidant therapies tested in cardiovascular disease such as vitamin E, C and β-carotene have proved unsuccessful at reducing cardiovascular events and mortality. Although these outcomes may reflect limitations in trial design, new, more […]

Astaxanthin increases choroidal blood flow velocity.

2018-03-19T22:01:21-05:00

Astaxanthin increases choroidal blood flow velocity. Abstract: Previous studies have reported that astaxanthin (AXT) has antioxidative and anti-inflammatory effects in addition to its ability to shorten blood transit times. As laser speckle flowgraphy (LSFG) can noninvasively visualize the hemodynamics of the choroidal circulation, we used the technique to evaluate whether continuous ingestion of 12 mg […]

Effects of astaxanthin on oxidative stress in overweight and obese adults

2018-03-19T21:22:22-05:00

Effects of astaxanthin on oxidative stress in overweight and obese adults.

Abstract: Oxidative stress is caused by an imbalance between the antioxidant and the reactive oxygen species, which results in damage to cells or tissues. Recent studies have reported that oxidative stress is involved in obesity, in addition to many other human diseases and aging. […]

Positive effects of astaxanthin on lipid profiles and oxidative stress in overweight subjects.

2018-03-22T21:59:21-05:00

Positive effects of astaxanthin on lipid profiles and oxidative stress in overweight subjects.

Abstract: Astaxanthin, a carotenoid, has antioxidant activity as well as many positive effects, such as anticancer and anti-inflammatory effects. We performed a randomized, double-blind, placebo-controlled study to investigate the effects of astaxanthin on lipid profiles and oxidative stress in overweight and obese […]

Effect of astaxanthin on cycling time trial performance

2018-03-19T21:48:56-05:00

Effect of astaxanthin on cycling time trial performance. Abstract: We examined the effect of Astaxanthin (AST) on substrate metabolism and cycling time trial (TT) performance by randomly assigning 21 competitive cyclists to 28 d of encapsulated AST (4 mg/d) or placebo (PLA) supplementation. Testing included a VO2max test and on a separate day a 2 h constant […]

Protective effects of Haematococcus astaxanthin on oxidative stress in healthy smokers

2018-03-19T22:01:01-05:00

Protective effects of Haematococcus astaxanthin on oxidative stress in healthy smokers. Abstract: Free radicals induced by cigarette smoking have been strongly linked to increased oxidative stress in vivo, contributing to the pathobiology of various diseases. This study was performed to investigate the effects of Haematococcus astaxanthin (ASX), which has been known to be a potent […]

Astaxanthin: A Potential Therapeutic Agent in Cardiovascular Disease

2018-03-22T21:43:46-05:00

Astaxanthin: A Potential Therapeutic Agent in Cardiovascular Disease Abstract: Astaxanthin is a xanthophyll carotenoid present in microalgae, fungi, complex plants, seafood, flamingos and quail. It is an antioxidant with anti-inflammatory properties and as such has potential as a therapeutic agent in atherosclerotic cardiovascular disease. Synthetic forms of astaxanthin have been manufactured. The safety, bioavailability and […]

Antioxidant effect of astaxanthin on phospholipid peroxidation in human erythrocytes

Antioxidant effect of astaxanthin on phospholipid peroxidation in human erythrocytes

Abstract: Phospholipid hydroperoxides (PLOOH) accumulate abnormally in the erythrocytes of dementia patients, and dietary xanthophylls (polar carotenoids such as astaxanthin) are hypothesised to prevent the accumulation. In the present study, we conducted a randomised, double-blind, placebo-controlled human trial to assess the efficacy of 12-week astaxanthin supplementation […]
