The level of human chorionic gonadotropin increases after pregnancy, and early pregnancy reactions such as nausea, vomiting, fatigue and weakness start to appear around one and a half months of pregnancy. The energy combination is made of 10% glucose plus inosine, coenzyme A and adenosine triphosphate, which are intermediate products of cellular metabolism and can directly improve the symptoms of fatigue and weakness. The intake of vitamin B6 and vitamin C can improve the symptoms of nausea and vomiting and enhance the intake of nutrients for pregnant women. The intake of amino acids provides energy for the growth and development of the baby, and the daily life of the pregnant woman, further improving the symptoms of fatigue and weakness. The discomfort will slowly disappear when the level of human chorionic gonadotropin starts to decline in the 8th-10th weeks of pregnancy.
