Founded in 1971, Tianweimei is a well-known vitamin and dietary supplement brand under Pharmavite in the United States, and has now been acquired by Otsuka Pharmaceutical of Japan. Tianweimei is the first vitamin brand in the United States to be recognized by the American Women's Medical Association AMWA, and has been a dietary supplement nutrition brand recommended by American pharmacists for ten consecutive years. Tianweimei has passed the United States Pharmacopeia test and certification, and is commonly found in Costco, CVS and other supermarket chains and pharmacies.
 
Tianweimei multivitamin products are rich in types, and there are corresponding products according to the user group, but it is more inclined to women, and the main multivitamins for pregnant women and postpartum people are recommended.
 
Prenatal Multivitamin Prenatal Multivitamin and Postnatal Multivitamin DHA are designed for pregnant women to supplement DHA with vitamins and minerals. DHA is beneficial to the brain development of infants and young children, and the amount of DHA in breast milk depends on the DHA intake of the nursing mother, and it is recommended that pregnant women consume no less than 200mg of DHA per day. There is little difference in fish oil content between the two vitamins during pregnancy, the main difference is that the content of vitamin A and D during pregnancy and childbirth is reduced by half, the content of vitamin A is 2567IU, vitamin D3 is 1000IU, and folic acid is increased to 800μg.
 
Pregnant women need to pay extra attention to folic acid and vitamin A, and it is recommended that women who are trying to conceive supplement 400-800μg of folic acid per day can reduce the risk of certain serious birth defects in the fetus. During pregnancy, pregnant women should also not use acne pills containing isotretinoin (an isomer of vitamin A), as their side effects will also increase the rate of teratogenicity.
 
Tianweimei also has a gummy-type multivitamin, which contains vitamins, minerals and fish oil, and also makes a distinction between people, which is also one of the features of its products, but it is not recommended to buy. The advantage of gummy vitamins is that they can be enriched with added sugars and other foods that enrich the monotonous taste of vitamin tablets, making them more like snacks. However, gummy multivitamins contain limited amounts of vitamins per capsule, and it is difficult to mix vitamins and gummies during production, making daily supplementation unstable. In the evaluation, Consumer Lab pointed out that gummies-based vitamins often do not meet the labeling value of the nutrition label, and are the most likely dietary supplement products to fail. Another disadvantage of gummy vitamins is that they are easy for children to eat as candy, which may cause vitamin overdose poisoning.
