Astaxanthin And Pregnancy: Understanding The Safety And Benefits

Astaxanthin is a carotenoid, a chemical found naturally in certain plants and animals. It is a powerful antioxidant, with anti-inflammatory properties, and is used to treat a range of conditions. It is not recommended for use during pregnancy or breastfeeding, as it may interfere with reproductive hormones. However, there is limited information available on its effects during these periods.

Astaxanthin's effect on hypertension during pregnancy

Astaxanthin is a powerful antioxidant that has been the subject of several studies investigating its potential effects on hypertension during pregnancy. While it is considered unsafe for consumption by pregnant women due to its interference with reproductive hormones, its potential benefits in preventing and treating preeclampsia (PE) have been explored.

Preeclampsia is a serious complication during pregnancy characterised by hypertension, high urea protein, and abnormalities in other systems. It is a leading cause of fatality in pregnant women and perinatal fetuses. The precise causes of PE remain unknown, but it has been associated with immunity, uterus-placental ischemia, endothelin, and nitrogen oxide (NO) dysfunction. Recent studies have also implicated extensive damage to the endothelium caused by oxidative stress and inflammation, resulting in reduced placental blood infusion.

The potential of astaxanthin to prevent and treat PE has been explored in several studies. Astaxanthin treatment has been found to significantly improve preeclamptic symptoms and reduce oxidative stress and inflammatory damage in preeclamptic placentas. In one study, astaxanthin increased HO-1 expression in L-NAME-induced preeclamptic rats, suggesting its ability to inhibit antioxidative damage and promote CO production. Additionally, astaxanthin has been shown to decrease blood pressure in hypertensive mice and increase the utility of NO, further supporting its potential role in managing hypertension associated with PE.

While these findings suggest a potential benefit of astaxanthin in preventing and treating PE-related hypertension, it is important to note that the USFDA Pregnancy Category for astaxanthin is unknown. Several research studies have indicated that astaxanthin may be unsafe for pregnant women due to its interference with reproductive hormones. Therefore, despite its potential benefits, pregnant women should exercise caution and consult their healthcare providers before considering astaxanthin supplementation.

Astaxanthin's effect on oxidative stress in the placenta

Astaxanthin is a powerful antioxidant derived from natural sources. It is known to be the strongest antioxidant ever discovered and is widely used in health food and biomedical research.

Several studies have been conducted to investigate the effects of astaxanthin on oxidative stress in the placenta. One such study by Xuan et al. in 2016 found that astaxanthin therapy significantly improved symptoms of preeclampsia and reduced oxidative stress and inflammatory damage in the placenta of preeclamptic rats. Preeclampsia is a common complication during pregnancy that is characterized by hypertension, high urea protein, and abnormalities in other systems. It is often associated with oxidative stress and inflammation, which can cause extensive damage to the endothelium and reduce placental perfusion.

The study by Xuan et al. is supported by other research that has found similar results. For example, Rong-rong et al. (2014) found that astaxanthin inhibited H2O2-induced oxidative stress in HUVECs and reduced oxidative stress and inflammatory damage in preeclamptic placentas. Additionally, Pongkan et al. investigated the effect of astaxanthin on mitochondrial dysfunction in ischemic mice, finding that it reduced mtROS production and mitochondrial depolarization.

While astaxanthin has shown promising results in reducing oxidative stress and inflammation in the placenta, it is important to note that there are conflicting findings regarding its safety during pregnancy. Some studies have suggested that astaxanthin may interfere with reproductive hormones and is therefore contraindicated during pregnancy. However, other studies have found no adverse effects on fetal development when astaxanthin has been administered to pregnant animals.

Astaxanthin's effect on inflammation in the placenta

Astaxanthin is a carotenoid pigment and antioxidant that occurs in trout, microalgae, yeast, and shrimp, among other sea creatures. It's most commonly found in Pacific salmon and is what gives the fish its pinkish color. Astaxanthin is an antioxidant, which means it helps reduce a natural process in your body called oxidation. This process may play a role in many diseases and changes such as eye diseases, rheumatoid arthritis, and carpal tunnel syndrome.

Astaxanthin has been shown to have anti-inflammatory properties, and can help protect the skin from developing sunburn or soothe a sunburn after its formation. It can also reduce inflammation and has been shown to decrease the expression of NF-κB, ROCK II, and caspase 3 in preeclamptic placentas.

Astaxanthin's effect on the immune system

Astaxanthin is a carotenoid, a chemical found naturally in certain plants and animals. It is a powerful antioxidant, with anti-inflammatory properties, and is thought to be the strongest natural antioxidant ever discovered. It is used as a supplement to treat a range of conditions, including:

• Eye diseases like cataracts and macular degeneration
• Rheumatoid arthritis
• Carpal tunnel syndrome
• Alzheimer's and Parkinson's diseases
• Peptic ulcers
• Kidney damage from diabetes
• It may also stimulate the immune system

Astaxanthin has been shown to have immunomodulatory effects, enhancing immune responses by enhancing IFN-γ and IL-2 secretion in primary cultured lymphocytes in vitro and ex vivo. It has been shown to increase the proliferation and transformation activities of spleen lymphocytes, activities of antibody-producing cells, serum hemolysin levels, and carbon particle clearance rate in mice. It has also been shown to improve delayed allergy reaction and NK cell activity.

Astaxanthin's effect on blood calcium levels

Astaxanthin is a red pigment that belongs to a group of chemicals called carotenoids. It is found in certain algae and causes the pink-red colour in salmon. It is an antioxidant, which means it helps reduce a natural process in your body called oxidation. This process may play a role in many diseases and changes such as eye diseases like cataracts and macular degeneration, rheumatoid arthritis, carpal tunnel syndrome, and Alzheimer's and Parkinson's diseases.

Astaxanthin has been found to decrease blood pressure and calcium levels. It is not recommended for women who are pregnant or might become pregnant.
