After 2004, Canadian health products were included in the regulatory system, which is considered to be the most stringent regulatory system for health products in the world. That is, the product must first pass the drug GMP, and then submit the detailed information, which is reviewed by the Federal Ministry of Health for 60 days before the product license can be obtained.
 
Founded in 1922, Bodybuilder is Canada's oldest vitamin manufacturer and a leader in the health supplement industry, with a 27% market share in the country. It has been awarded the title of Canada's most trusted brand in the category of nutritional supplements for 6 consecutive years since 2014, and was elected as the third reputable company in Canada in 2019.
 
Sold to a U.S. private equity firm in 2014, the brand went public in Toronto in July 2017 with good growth momentum, taking advantage of an aging population and growing disposable income. As early as 2002, it has entered China and amassed a huge user base. Due to Canadian regulations, most of the bodybuilding products are directly imported from overseas and limited to online sales, and Rao has also achieved sales of more than 100 million yuan in China in 2017.
 
Bodybuilders provide calcium supplements in tablets with different calcium sources, the most popular of which is Mega Cal Calcium D3, which has five calcium sources: calcium carbonate, calcium citrate, calcium fumarate, calcium malate and calcium succinate, with vitamin D3 absorption. Multiple sources of calcium do not improve calcium absorption as advertised, and the only inorganic calcium calcium carbonate has the highest content according to the order of ingredients on the label, so it should still be taken with a meal. Five-fold calcium contains 650mg of calcium per capsule, and the recommended dosage of up to 2 tablets per day exceeds the recommended intake in China and the United States, and it is recommended to reduce it to 1 tablet per day. 120 capsules are sold for 89 yuan, which is cost-effective in calcium carbonate, and it is cost-effective considering that it contains a small amount of organic calcium.
 
Calcium Magnesium & Vitamin D3和五重钙有相同钙源，每粒含钙330mg和镁167mg，每日最高3粒的推荐量相对合理。Calcium Magnesium & Zinc在这一基础上用葡萄糖酸锌替代维生素D，更适合成长发育期人群服用，三种矿物质比例合理，200片约169元，不算便宜。
 
健美生大部分Calcium supplements为细长片剂，形状方便吞咽但个头不小。Super Calcium & Vitamin D3是唯一一款迷你钙片，每粒重约1.72g，比同品牌片剂体积小35%。它以牡蛎提取物为钙源，就成分、钙含量而言可做五重钙的小粒替代品，但每日补钙成本是五重钙的2倍，除非是吞咽困难人群，否则不作推荐。
 
健美生也提供市场上为数不多的柠檬酸钙Calcium Citrate & Vitamin D3，每片含钙250mg，推荐用量为每日4片，正好是中国推荐成人摄入量。鉴于膳食途径也有钙摄入，更建议调整为每日3片。120片约240元，性价比不如Swisse，略优于Citracal的迷你钙片。
