Buy Astaxanthin Antioxidant Carotenoid, Source Naturals, 2 mg, 60 Softgels

Astaxanthin is a naturally occurring carotenoid that is closely related to beta-carotene and Lutein. Because of its unique structure, astaxanthin provides a wide range of antioxidant benefits. Astaxanthin may play a key role in the protection of cell membranes against free radical attack. Astaxanthin is a natural concentrate of marine algae Haematococcus pulvialis, which is cultivated in the warm waters of Hawaii. Recent studies have indicated that astaxanthin is more powerful than its carotenoid cousin, beta-carotene, at trapping singlet oxygen free radicals.

Astaxanthin Research Update
A preliminary investigation of the enzymatic inhibition of 5alpha-reduction and growth of prostatic carcinoma cell line LNCap-FGC by natural astaxanthin and Saw Palmetto lipid extract in vitro.
J Herb Pharmacother. 2005;5(1):17-26. Anderson ML.
Research and Development, Triarco Industries, Wayne, NJ 07470
Inhibition of 5alpha-reductase has been reported to decrease the symptoms of benign prostate hyperplasia (BPH) and possibly inhibit or help treat prostate cancer. Saw Palmetto berry lipid extract (SPLE) is reported to inhibit 5alpha-reductase and decrease the clinical symptoms of BPH. Epidemiologic studies report that carotenoids such as lycopene may inhibit prostate cancer. In this investigation the effect of the carotenoid astaxanthin, and SPLE were examined for their effect on 5alpha-reductase inhibition as well as the growth of prostatic carcinoma cells in vitro. The results show astaxanthin demonstrated 98% inhibition of 5alpha-reductase at 300 microg/mL in vitro. Alphastat, the combination of astaxanthin and SPLE, showed a 20% greater inhibition of 5alpha-reductase than SPLE alone n vitro. CONCLUSIONS: Low levels of carotenoid astaxanthin inhibit 5alpha-reductase and decrease the growth of human prostatic cancer cells in vitro. Astaxanthin added to SPLE shows greater inhibition of 5alpha-reductase than SPLE alone in vitro.

Prevention of diabetic nephropathy by treatment with astaxanthin in diabetic db/db mice.
Biofactors. 2004;20(1):49-59.
Oxidative stress is implicated as an important mechanism by which diabetes causes nephropathy. Astaxanthin, which is found as a common pigment in algae, fish, and birds, is a carotenoid with significant potential for antioxidative activity. In this study, we examined whether chronic administration of astaxanthin could prevent the progression of diabetic nephropathy induced by oxidative stress in mice. The mice were divided into three groups as follows: non-diabetic, diabetic, and diabetic treated with astaxanthin. After 12 weeks of treatment, the astaxanthin -treated group showed a lower level of blood glucose compared with the non-treated db/db group. The results suggested that the antioxidative activity of astaxanthin reduced the oxidative stress on the kidneys and prevented renal cell damage. In conclusion, administration of astaxanthin might be a novel approach for the prevention of diabetes nephropathy.

Antihypertensive and neuroprotective effects of astaxanthin in experimental animals.
Biol Pharm Bull. 2005 Jan;28(1):47-52.
Astaxanthin is a natural antioxidant carotenoid that occurs in a wide variety of living organisms. We investigated, for the first time, antihypertensive effects of astaxanthin in spontaneously hypertensive rats (SHR). Oral administration of astaxanthin for 14 d induced a significant reduction in the arterial blood pressure (BP) in SHR but not in normotensive Wistar Kyoto (WKY) strain. The long-term administration of astaxanthin (50 mg/kg) for 5 weeks in stroke prone SHR (SHR-SP) induced a significant reduction in the BP. It also delayed the incidence of stroke in the SHR-SP. To investigate the action mechanism of astaxanthin, the effects on PGF(2alpha)-induced contractions of rat aorta treated with NG-nitro-L-arginine methyl ester (L-NAME) were studied in vitro. Astaxanthin induced vasorelaxation mediated by nitric oxide (NO). The results suggest that the antihypertensive effect of astaxanthin may be due to a NO-related mechanism. astaxanthin also showed significant neuroprotective effects in ischemic mice, presumably due to its antioxidant potential. Pretreatment of the mice with astaxanthin significantly shortened the latency of escaping onto the platform in the Morris water maze learning performance test. In conclusion, these results indicate that astaxanthin can exert beneficial effects in protection against hypertension and stroke and in improving memory in vascular dementia.

Alpha-tocopherol and astaxanthin decrease macrophage infiltration, apoptosis and vulnerability in atheroma of hyperlipidaemic rabbits.
J Mol Cell Cardiol. 2004 Nov;37(5):969-78.
The composition of atherosclerotic plaques, not just macroscopical lesion size, has been implicated in their susceptibility to rupture and the risk of thrombus formation. By focusing on the quality of lipids, macrophages, apoptosis, collagen, metalloproteinase expression and plaque integrity, we evaluated the possible anti-atherosclerotic effect of the antioxidants alpha-tocopherol and astaxanthin in Watanabe heritable hyperlipidemic (WHHL) rabbits. Thirty-one WHHL rabbits were divided into three groups and were fed a standard diet, as controls (N =10), or a standard diet with the addition of 500 mg alpha-tocopherol per kg feed (N =11) or 100 mg astaxanthin per kg feed (N =10) for 24 weeks. We found that both antioxidants, particularly astaxanthin, significantly decreased macrophage infiltration in the plaques although they did not affect lipid accumulation. All lesions in the astaxanthin-treated rabbits were classified as early plaques according to the distribution of collagen and smooth muscle cells. Both antioxidants also improved plaque stability and significantly diminished apoptosis, which mainly occurred in macrophages, matrix metalloproteinase three expressions and plaque ruptures. Although neither antioxidant altered the positive correlations between the lesion size and lipid accumulation, the lesion size and apoptosis were only positively correlated in the control group. Astaxanthin and alpha-tocopherol may improve plaque stability by decreasing macrophage infiltration and apoptosis in this atherosclerotic setting. Apoptosis reduction by alpha-tocopherol and astaxanthin may be a new anti-atherogenic property of these antioxidants.

In vitro effects of astaxanthin combined with ginkgolide B on T lymphocyte activation in peripheral blood mononuclear cells from asthmatic subjects.
J Pharmacol Sci. 2004 Feb;94(2):129-36.
This study was undertaken to identify novel approaches to pharmacological treatment of asthma. Here we hypothesize that the platelet-activating factor receptor antagonist ginkgolide B (GB) in combination with the antioxidant carotenoid astaxanthin suppresses T cell activation comparably to two commonly-used antihistamines: cetirizine dihydrochloride (CTZ) and azelastine (AZE). These results suggest that astaxanthin and GB may have application as novel antiasthmatic formulations.

Astaxanthin limits exercise-induced skeletal and cardiac muscle damage in mice.
Antioxid Redox Signal. 2003 Feb;5(1):139-44.
Dietary antioxidants may attenuate oxidative damage from strenuous exercise in various tissues. Beneficial effects of the antioxidant astaxanthin have been demonstrated in vitro, but not yet in vivo. We investigated the effect of dietary supplementation with astaxanthin on oxidative damage induced by strenuous exercise in mouse gastrocnemius and heart. C57BL/6 mice (7 weeks old) were divided into groups: rested control, intense exercise, and exercise with astaxanthin supplementation. After 3 weeks of exercise acclimation, both exercise groups ran on a treadmill at 28 m/min until exhaustion. Exercise-increased 4-hydroxy-2-nonenal-modified protein and 8-hydroxy-2'-deoxyguanosine in gastrocnemius and heart were blunted in the astaxanthin group. Increases in plasma creatine kinase activity, and in myeloperoxidase activity in gastrocnemius and heart, also were lessened by astaxanthin. Astaxanthin showed accumulation in gastrocnemius and heart from the 3 week supplementation. Astaxanthin can attenuate exercise-induced damage in mouse skeletal muscle and heart, including an associated neutrophil infiltration that induces further damage.

Oral bioavailability of the antioxidant astaxanthin in humans is enhanced by incorporation of lipid based formulations.
Eur J Pharm Sci. 2003 Jul;19(4):299-304.
Astaxanthin is a carotenoid with antioxidant properties, synthesised by plants and algae, and distributed in marine seafood. Astaxanthin is also available as a food supplement, but, like other carotenoids, is a very lipophilic compound and has low oral bioavailability. However, astaxanthin bioavailability can be enhanced in the presence of fat.

Safety of an astaxanthin-rich Haematococcus pluvialis algal extract: a randomized clinical trial.
J Med Food. 2003 Spring;6(1):51-6.
A growing body of scientific literature indicates that astaxanthin is a more powerful antioxidant than other carotenoids and vitamin E and may confer numerous health benefits. The purpose of this investigation was to conduct a human safety study with a Haematococcus pluvialis algal extract with high levels of astaxanthin. Thirty-five healthy adults age 35-69 years were enrolled in a randomized, double-blind, placebo-controlled trial of 8 weeks' duration. All participants took three gelcaps per day, one at each meal. Nineteen participants received gelcaps with an algal extract in safflower oil, containing 2 mg of astaxanthin each (treatment); 16 participants received gelcaps containing safflower oil only (placebo). Blood pressure and blood chemistry tests, including a comprehensive metabolic panel and cell blood count, were conducted at the beginning of the trial and after 4 and 8 weeks of supplementation. No significant differences were detected between the treatment and the placebo groups after 8 weeks of supplementation with astaxanthin in the parameters analyzed, except for serum calcium, total protein, and eosinophils. Although the differences in these three parameters were statistically significant, they were very small and are of no clinical importance. These results reveal that 6 mg of astaxanthin per day from a H. pluvialis algal extract can be safely consumed by healthy adults.

Haematococcus astaxanthin: applications for human health and nutrition.
Trends Biotechnol. 2003 May;21(5):210-6.
The carotenoid pigment astaxanthin has important applications in the nutraceutical, cosmetics, food and feed industries. Haematococcus pluvialis is the richest source of natural astaxanthin and is now cultivated at industrial scale. Astaxanthin is a strong coloring agent and a potent antioxidant - its strong antioxidant activity points to its potential to target several health conditions. This article covers the antioxidant, UV-light protection, anti-inflammatory and other properties of astaxanthin and its possible role in many human health problems. The research reviewed supports the assumption that protecting body tissues from oxidative damage with daily ingestion of natural astaxanthin might be a practical and beneficial strategy in health management.

Commercial potential for Haematococcus microalgae as a natural source of astaxanthin.
Trends Biotechnol. 2000 Apr;18(4):160-7.
As a result of high production costs, commercial products from microalgae must command high prices. Astaxanthin produced by Haematococcus is a product that has become a commercial reality through novel and advanced technology. Cultivation methods have been developed to produce Haematococcus containing 1.5-3.0% astaxanthin by dry weight, with potential applications as a pigment source in aquaculture, poultry feeds and in the worldwide nutraceutical market.

Q. I bought an astaxanthin product a few weeks ago. I notice there is a warning that astaxanthin is not intended for long term use. What is the time period I can safely use astaxanthin?
     A. Each person is different in their need for astaxanthin, so it is impossible to say how long to take it, but a good option if your doctor approves is to take astaxanthin every other day and take one week off per month. This is a very general guideline.

Q. Regarding the warning on "long term use"- what danger is there in taking astaxanthin in such a way? What constitutes "long term use"? I'm really excited about astaxanthin supplement but I don't want to overdose or hurt myself with it.
   A. Since there have not been long term studies with astaxanthin supplement use in humans, we don't know if there are risks to its use. We are very cautious and conservative in our approach, and we prefer to err on the side of safety and prevention. It is a good idea to take occasional breaks from use, For instance, if a person take a week off each month then that might be a good idea.

Q. I am doing a little personal research on antioxidants. I came across information on astaxanthin, which seems very impressive. But as yet I have not been able to ascertain what it's ORAC (Oxygen Radical Absorbance Capacity) score is.
   A. We did a Medline search for the term " astaxanthin ORAC value " in August 2007 and did not find an answer.

Q. I saw this supplement "Astaxanthin, 2 mg 60 softgels" . I just wanted to know before buying it , if these soft gels are made from " pork gelatin " If yes , unfortunately i might not be able to take it , In that case can you please recommend me any other supplement with high dose of astaxanthin but at the same time " animal especially pork gelatin-FREE."
   A. We are not familiar with an astaxanthin supplement without gelatin, but there may be some if you do a google search.
