Ferguson Biotechnology Co., Ltd. is a professional in maternal and infant nutrition in China, and in 2004 produced China's first health care product approved by the State Food and Drug Administration to use the word "pregnant woman". It has project cooperation with the Ministry of Health, Peking University Medical Department and other units, focusing on gastrointestinal temperature and nutrition, and won the title of national postdoctoral research station in 2012. Due to the positioning of users as pregnant women and the recognition of the State Food and Drug Administration, Ferguson has been recommended by many obstetricians and gynecologists, but it lacks recognition among general users, and the price is relatively high.
 
Ferguson produces only one specialty calcium supplement and is also allowed to use the term "pregnant nursing mother" in the product name. Constipation is one of the common symptoms during pregnancy, and pregnant women pay more attention to digestion than ordinary calcium tablets. The calcium source of Fergusonvid D3 Calcium Tablets (Pregnant Nursing Mother) still uses the lower-cost calcium carbonate, but it is fully pulverized by ultra-fine grinding technology and additionally added casein phosphopeptide (CPP). CPP is a food nutrition enhancer enshrined in the national standard, which can promote calcium absorption like vitamin D, and in the casein micelles formed by CPP, phosphate anions and calcium ions can be stably presented, and it is not easy to precipitate during transportation, so as to avoid the risk of constipation.
 
Fergusonvid D3 Calcium Tablets (Pregnant Nursing Mother) contains 500mg of calcium per capsule, 1 capsule is recommended for 1 day, chewed. According to the survey, the daily calcium intake of Chinese women during pregnancy does not exceed 400mg, based on this basis, the additional supplement of 500mg/day is still conservative, but taking 2 capsules is absolutely excessive, and it is recommended that pregnant women and nursing mothers ensure adequate dietary intake of calcium sources.
 
In order to improve the taste and taste, Fergusonwei D3 calcium tablets (pregnant women's nursing type) are added with sweeteners, orange powder and gelatin, and there are three specifications: 20 capsules, 30 capsules, and 60 capsules, 60 capsules are the most cost-effective, but the average price of each capsule is also more than 3 yuan, and the cost performance is low.
