Founded in 1995, By-Health is one of the first local companies to introduce dietary supplements into China, and now with the absolute advantage of market share, By-Health is undoubtedly the leading brand in China's dietary supplement industry. Unlike direct selling giants such as Infinitus and Amway, By-Health has focused on online e-commerce in recent years, and its sales channels and product lines are moving closer to the younger generation. Soon after developing the e-commerce channel, By-Health surpassed Swisse and became the No. 1 dietary supplement brand in sales on the Alibaba platform, and ranked first in 2017 and 2018 for two consecutive years.
 
The calcium amount design of Tomson Bio-Health calcium supplement products is very suitable, which is more in line with the recommended calcium intake in China and the dietary habits of Chinese people. The brand did not put too much thought into the difference in the digestion of calcium, but used different additives to distinguish the auxiliary effects of calcium, so Tomson Beijian calcium has more functions but a single calcium source. Its calcium source is calcium carbonate, which is only suitable for people with normal gastric acid secretion.
 
The most common By-Health calcium products on the market are liquid calcium softgels and calcium vitamin D and vitamin K softgels, which are liquid calcium supplements in soft capsules, which are easier to swallow and digest than other solid calcium tablets of the brand. The latter is an upgraded product of the former, which significantly increases the vitamin D content and adds vitamin K on the basis of the former's formula. Since the price of the two is similar, it is recommended to choose the upgraded new product. Calcium vitamin D vitamin K soft capsules contain 250mg of calcium, 180 IU of vitamin D per capsule, the intake of two capsules per day is relatively sufficient and not excessive, the price is about 200 capsules 100 yuan, and it is also the most cost-effective calcium supplement product of Tomson Beijian.
 
Due to their special function of maintaining joints, collagen chondroitin calcium tablets and glucosamine chondroitin calcium tablets have attracted high attention among middle-aged and elderly people. The main ingredients of the former are calcium carbonate, collagen and chondroitin sulfate, while the selling point of the latter is glucosamine and chondroitin sulfate.
 
Health products such as chondroitin sulfate and ammonia sugar are mostly used to relieve pain symptoms such as arthritis and joint pain. However, in fact, there is still academic controversy about these two substances, and their benefits are not clear, but because there are no obvious toxic side effects, patients who are willing to try it can still take it, according to the doctor's advice, it is recommended to stop taking the drug for half a year without obvious improvement, among which those who are allergic to seafood need to be cautious about taking ammonia sugar supplements. As for the collagen in collagen chondroitin calcium tablets, it is a marketing concept, and there is no conclusive evidence to support the conclusion that "collagen can maintain joint health".
 
These two special calciums do not contain vitamin D. The amount of calcium in collagen chondroitin calcium tablets is similar to that of calcium vitamin D and vitamin K soft capsules, about 80 yuan for 90 capsules. Chondroitin calcium tablets are slightly lower in calcium, about 50 yuan for 40 capsules. In general, the cost performance of the two calcium supplements is not high, especially the calcium tablets of aminoglucochondroitin, and it is not recommended for people with healthy joints to buy these two calcium supplements for calcium supplementation.
 
Tomson Beijian's calcium, iron and zinc chewable tablets are more suitable for children and adolescents because of their sweet and sour taste, but similar to the above two calcium tablets, the cost performance is low, 60 tablets are about 80 yuan, which is higher than most calcium supplements according to the amount of calcium.
