|February 18, 2011
Summary
Evidence is insufficient to determine if vitamin D supplementation during pregnancy impacts outcomes. More research is needed to understand the effects of vitamin D on maternal and infant health.
Area of Science:
- Obstetrics and Gynecology
- Nutritional Science
- Maternal-Fetal Medicine
Background:
- Vitamin D deficiency is common in individuals with limited dietary intake or sun exposure.
- Adequate vitamin D levels are crucial for both maternal and fetal health during pregnancy.
Purpose of the Study:
- To systematically review the existing evidence on the effects of vitamin D supplementation during pregnancy.
- To assess the impact of vitamin D on various pregnancy outcomes.
Main Methods:
- Searched Cochrane Pregnancy and Childbirth Group trials register and Cochrane Controlled Trials Register.
- Included acceptably controlled trials of vitamin D supplementation in pregnant women.
- Assessed trial quality and extracted data by a single reviewer.
Main Results:
- Two trials with 232 women were analyzed.
- One trial indicated higher maternal weight gain and fewer low birthweight infants with supplementation.
- The other trial reported lower birthweights in the supplemented group.
Conclusions:
- Current evidence is insufficient to evaluate the effects of vitamin D supplementation during pregnancy.
- Further high-quality trials are necessary to establish definitive conclusions.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:22Connective Tissue Cell Types
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:18Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
