Pregnancy anemia and pregnancy-induced hypertension (PIH) are common and potentially dangerous disorder in human pregnancy, and nutritional status of pregnant women is one of the leading causes. Chlorella contains large quantities of folate, vitamin B-12 and iron, and can help improve anemia and hypertensive disorder. Our objective was to investigate the preventive effects of Chlorella supplement on pregnancy anemia and PIH in Japanese pregnant women. A total of 70 pregnant women were placed into the control group (n = 38) or the Chlorella group (n = 32). The subjects in the Chlorella group were supplemented daily from 12th-18th wk of gestation until delivery with 6 g of Chlorella supplement. The proportion of anemic (hemoglobin level < 11 g/dL) subjects in the Chlorella group were significantly lower compared with the control group at the second and third trimesters. Additionally, in the Chlorella group, the incidences of proteinuria and edema, signs of PIH, were significantly lower during the third trimester. These results suggest that Chlorella supplementation significantly reduces the risk of pregnancy associated anemia, proteinuria and edema. Chlorella supplement may be useful as a resource of natural folate, vitamin B-12 and iron for pregnant women.
妊娠贫血和妊娠高血压（PIH）是人类妊娠中常见且潜在危险的疾病，孕妇的营养状况是主要原因之一。绿藻含有大量的叶酸、维生素 B-12 和铁，可以帮助改善贫血和高血压疾病。我们的目的是研究绿藻补充剂对日本孕妇妊娠贫血和 PIH 的预防作用。共有 70 名孕妇被分为对照组（n = 38）或绿藻组（n = 32）。绿藻组的受试者从妊娠 12-18 周开始每天补充 6 克绿藻补充剂，直至分娩。与对照组相比，绿藻组在第二和第三个三个月的贫血（血红蛋白水平<11g/dL）患者比例显著降低。此外，在绿藻组中，第三孕期蛋白尿和水肿的发生率（PIH 的迹象）显著降低。这些结果表明，绿藻补充剂可显著降低妊娠相关贫血、蛋白尿和水肿的风险。绿藻补充剂可能是孕妇天然叶酸、维生素 B-12 和铁的有用来源。
