Water-soluble vitamins, which include the B-complex group and vitamin C, dissolve easily in water and are not stored in large amounts in the human body. Excess amounts are routinely filtered out by the kidneys and excreted in the urine. Because of this continuous elimination, you must ingest these nutrients on a regular basis through your daily diet to prevent depletion. During pregnancy and lactation, maternal requirements for water-soluble vitamins rise significantly to support rapid cell division, increased blood volume, and milk production. Midwives in Nigerian clinical settings frequently encounter dietary challenges, making a strong grasp of these vitamins vital for promoting healthy maternal and neonatal outcomes.
The B-complex family consists of eight distinct water-soluble micronutrients that work closely together as metabolic coenzymes. They include thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12). Each member plays a unique part in energy production, nervous system maintenance, and cellular growth. Vitamin C, also known as ascorbic acid, stands apart as a powerful antioxidant that supports immune defense and connective tissue repair. Together, these nutrients form an essential biochemical network that keeps maternal tissues resilient during the physical stress of childbearing.
Lack of water-soluble vitamins triggers distinct clinical syndromes that can threaten maternal and fetal well-being. Folate deficiency during early gestation drastically increases the risk of neural tube defects such as spina bifida. A shortage of Vitamin B12 or folate leads to megaloblastic anaemia, characterized by large, immature, poorly functioning red blood cells and profound maternal fatigue. Vitamin C deficiency results in scurvy, marked by bleeding gums, poor wound healing, and fragile capillaries. Meanwhile, thiamine deficiency can cause beri-beri, which affects the cardiovascular and nervous systems, presenting with muscle weakness and peripheral neuropathy.
Meeting vitamin needs is achievable through diverse, locally available Nigerian foods. Folate is abundant in dark green leafy vegetables like ugu (fluted pumpkin leaves), ewedu, and waterleaf, as well as legumes like cowpeas. Vitamin C is easily obtained from fresh citrus fruits like oranges and grapefruits, alongside tomatoes, pawpaw, and bell peppers (tatashe). B-complex vitamins are found in whole grains, brown rice, local millet, groundnuts, beans, and organ meats such as liver. Midwives should encourage women to consume a colorful variety of these foods daily rather than relying solely on synthetic pills.
Effective midwifery care involves educating pregnant and lactating women on how to preserve water-soluble vitamins during food preparation. Vitamins like C and the B-group are sensitive to heat, light, and prolonged boiling; overcooking vegetables or discarding cooking water strips away these vital nutrients. Midwives should also advise women on proper supplement adherence, explaining that iron and folate tablets work best when taken with clean water or citrus juice rather than tea or coffee, which can hinder absorption. Culturally sensitive dietary counseling ensures mothers make informed, practical choices using affordable local ingredients.
