Summary: Pregnant mothers should not only pay attention to a reasonable diet and supplement nutrition, but also use vitamins, mineral tablets and other products. Among them, multi-dimensional tablets are popular among pregnant mothers because they can supplement a variety of nutrients at the same time and are easy to use. How to supplement nutrition during pregnancy to be more healthy and effective? Pregnancy is a complex process. Mothers must not only take in nutrients to meet their own physiological needs, but also take in nutrients needed for fetal growth and development. Therefore, in addition to paying attention to a reasonable diet and nutritional supplements, many pregnant mothers also use vitamins, mineral tablets and other products. Among them, multivitamin tablets are popular among pregnant mothers because they can supplement a variety of nutrients at the same time and are easy to use. How to supplement nutrition during pregnancy to be more healthy and effective?
Nutritional supplements during pregnancy are crucial
But make it clear
Wen Jiying, chief physician of the Obstetrics Department of Guangdong Maternal and Child Health Hospital, pointed out that the \”fetal theory of adult diseases\” in the medical community believes that in addition to genetic factors, the occurrence of many adult diseases is also related to the intrauterine environment and acquired environmental factors. During critical moments of life and development, the intrauterine environment can cause permanent changes in the body\’s internal structure and function. For example, insufficient supply of nutrients to the fetus can lead to poor fetal growth and development, which in turn can cause long-term changes in body physiology and metabolism, and is the cause of chronic diseases in adulthood. Hidden dangers arise. Therefore, reasonable dietary nutrition is not only related to the health of pregnant women themselves, but also to the health of their fetuses.
Dr. Wen Jiying emphasized that you can use multivitamins and multivitamin tablets on the market, but it is more important to know which vitamins you lack and how much you need to supplement through nutritional examination and doctor\’s evaluation, just in case you take too much or take too much. Insufficient income. bring risks.
Folic acid: supplementation should be started during pregnancy
Dr. Wen Jiying said that early pregnancy is a critical period for the development of fetal neurological organs, and folic acid has been proven to be closely related to fetal neural tube defects. Therefore, pregnant mothers should supplement folic acid when preparing for pregnancy.
Dr. Wen Jiying suggests that women of childbearing age should eat more animal livers, dark green leafy vegetables such as spinach, beans and some fruits such as grapefruit, which are rich in folic acid, starting at least 3 months before pregnancy. However, since folic acid supplementation is better absorbed and utilized by the body than folic acid in food, it is recommended to start supplementing 400 grams of folic acid every day at least 3 months before pregnancy to maintain an appropriate level of folic acid in the body. level to ensure early fetal development. Folic acid has a good nutritional status and can prevent fetal neural tube and other organ malformations.
Dr. Wen Jiying emphasized that since the neural tube has already formed in the early stages of pregnancy (around 7 weeks), some pregnant mothers do not know that they are pregnant. Starting supplements too late will not have a good preventive effect, so it is best to supplement with folic acid. The time should be from 3 months before pregnancy to 3 months in the first trimester.
Calcium: Calcium requirements increase after the fifth month of pregnancy
Dr. Wen Jiying said that after 5 months of pregnancy, the baby’s bones and teeth develop rapidly.period, so the demand for calcium also increases. The recommended calcium intake for women in the first trimester is 800mg/day, and for women in the second and third trimesters, it is 1000mg/day. During this period, pregnant mothers should supplement calcium-rich foods, such as milk, soy products, eggs, fish and shrimp, bone soup, etc. If necessary, supplement calcium and vitamin D, which can effectively promote calcium absorption.
The data showed that calcium levels varied widely among the samples tested. For example, the calcium content of Suncun multivitamin soft capsules (pregnancy) and Swisse pregnancy multivitamin capsules are 0.02mg/tablet and 18.1mg/tablet respectively. The calcium content of the other 7 products ranges from 50.1mg to 328.6mg. It is recommended that pregnant women choose the appropriate dosage of products based on their own dietary records and doctor\’s guidance.
Iodine: iodine supplementation during pregnancy cannot rely solely on iodized salt
Dr. Wen Jiying said that due to the immaturity of thyroxine during pregnancy and the immature brain development of the embryo, the mother needs more thyroxine, and the content increases rapidly as the pregnancy progresses. The concentrations of T3 (triiodothyronine) and T4 (tetraiodothyronine) increase during late pregnancy and before delivery, which is needed to maintain the metabolism of pregnant women and accelerate compensation.
Among the samples tested, the iodine content of Kingsley multivitamin tablets (during pregnancy) and Suncun multivitamin mineral soft capsules (during pregnancy) was 0. Among them, Swisse multivitamin capsules for pregnancy had the highest iodine content at 190 grams per tablet.
The recommended daily intake of iodine for women in early, middle and late pregnancy is 230 grams. The recommended daily intake of iodized salt is 6 grams, and cooking provides about 120 grams of iodine. Dr. Wen Jiying said that sufficient iodine needs to be supplemented during pregnancy to meet the needs of the mother and fetus.

What is the difference between health supplement vitamins and pharmaceutical vitamins?
According to statistics from the \”Incidence and Etiology of Drug-Induced Liver Injury in Mainland China\”, health products and Chinese patent medicines have become important causative factors of drug-induced liver injury in my country, accounting for 26.81%. Along with various supplements, not only nutrients but also toxic ingredients such as heavy metals enter the human body.
The evaluation showed that 6 samples of GNC Pregnancy Multivitamins, Kingsley Multivitamin Tablets (pregnancy), Nature Pregnancy Comprehensive Nutrition Soft Capsules, Rupei Multivitamin Mineral Tablets (pregnant women), and Wyeth Maternal and Infant Multivitamin Tablets were tested. Heavy metal elements were found, including pregnancy multivitamins, Australian Jiabao pregnancy multivitamins, 4 samples with lead and arsenic content of 0.03~0.11mg/kg, 3 samples with cadmium content of 0.04~0.12mg/kg, and 6 samples with aluminum content of 25mg/kg~135mg. Sample/kg.
Heavy metals are ubiquitous in air, water and soil and can be enriched by plants and animals, so the raw materials of products may contain heavy metals. Current national standardsThe limit for lead in health foods is 2 mg/kg, and the limit for arsenic is 1 mg/kg. None of the tested samples exceeded the standards; the limits for cadmium and aluminum are not clearly marked.
Regarding nutritional supplements for pregnant mothers, Dr. Wen Jiying suggested that we should first start with natural food supplements and then consider nutritional supplements. Health vitamin products and medicinal vitamin products have different nutritional components and effects. Use under guidance. ——New Express reporter Chen Sitao and correspondent Lin Huifang
