No matter how much we try to normalize pregnancy, it brings about monumental changes in a woman's body. From hormones to blood pressure, blood sugar levels, and all vital organs—almost every system is affected as the body adapts to support the growth of a new life.
The Complexity of Pregnancy
Pregnancy is not merely a physical condition—it is a complex biological process that demands continuous adjustments over nine months. Hormonal shifts are among the earliest and most noticeable changes, influencing mood, energy levels, sleep, and metabolism. Many women experience thick, lustrous hair during pregnancy due to hormonal changes that prolong the growth phase of hair. Blood volume increases significantly to nourish the developing baby, causing the heart to work harder and circulation to alter. Blood pressure may fluctuate, while insulin sensitivity can become erratic, sometimes leading to gestational diabetes. The musculoskeletal system experiences strain as posture shifts and ligaments loosen in preparation for childbirth.
Despite these challenges, pregnancy is a remarkable demonstration of the body's resilience and intelligence. It constantly recalibrates itself to nurture and protect new life. While many women continue daily routines through pregnancy, it is important to recognize the immense internal work taking place and offer understanding, care, and support throughout this life-changing journey.
It is a common belief that women during pregnancy suffer primarily from iron deficiency. However, many other nutrients require attention during this delicate period. In India, iron and folic acid have long been the cornerstone of maternal supplementation. Yet the country continues to face a significant burden of maternal malnutrition, with 52% of pregnant women estimated to be anemic according to the National Family Health Survey (NFHS-5). While iron and folic acid are certainly crucial, pregnancy nutrition often requires a broader and more sustained approach. Several other micronutrients also play an important role during pregnancy and well into the first 1000 days of the baby's life.
Key Nutrient Groups for Maternal Supplementation
1. Iron and Folic Acid
Iron supports hemoglobin, which carries oxygen through the blood. During pregnancy, blood volume increases significantly, leading to higher iron requirements. Low iron levels can cause fatigue in the mother and reduced oxygen supply to the baby. Folic acid supports early cell division and development, particularly in the formation of the baby's brain and spinal cord. These two nutrients remain the foundation of antenatal care.
“Addressing iron deficiency is critical, especially in a country where anaemia remains widespread,” says Dr. Vinay Purohit, MBBS, MD (Pharmacology), LLB. “But pregnancy does not increase the body's need for iron alone. The body is creating more blood, supporting organ development, and maintaining maternal strength, all at once. If fatigue or weakness persist despite iron supplementation, it may signal the need to look at overall nutrition rather than focus on a single nutrient.”
2. Vitamin B12 and Vitamin B6
Vitamin B12 supports red blood cell formation and energy metabolism. It also plays an important role in the development of the baby's nervous system. There is a high prevalence of vitamin B12 deficiency in Indian women during pregnancy. Studies estimate it affects between 40% and 70% of expectant mothers, particularly those with predominantly vegetarian diets where natural sources are limited. Vitamin B6 supports nerve function and contributes to appetite regulation and managing nausea in early pregnancy.
Dr. Alaka Godbole, M.D. (Gynaecology & Obstetrics), FICOG, P.G.D.M.L.S., says, “Maternal nutrition requires a comprehensive and sustained approach, as nutritional needs evolve across different stages of pregnancy and lactation. Moving beyond a limited focus on iron and folic acid to a broader spectrum of essential micronutrients including calcium, which is critical for maternal bone health and fetal development, is the key to improving outcomes. Ensuring the right balance of nutrients can support healthier pregnancies and better long-term outcomes for both mother and child.”
3. Calcium, Vitamin D, and Magnesium
According to several studies, calcium supports skeletal development in the baby and helps maintain bone strength in the mother. Dietary assessment in India suggests that calcium intake during pregnancy often falls below recommended levels. Vitamin D helps the body absorb calcium effectively while supporting muscle and immune function. Low vitamin D levels are widely observed in Indian populations despite abundant sunlight, possibly due to limited outdoor exposure, higher skin pigmentation reducing vitamin D synthesis, and cultural practices limiting direct sun exposure. Magnesium supports muscle and nerve function and contributes to overall musculoskeletal balance, especially as pregnancy advances and cramps or muscular discomfort become more common.
It is advised to consume iron and calcium at separate times of the day, allowing at least a two-hour gap, because calcium can reduce iron absorption if taken together. Small practical adjustments can significantly improve both tolerance and effectiveness.
4. Zinc and Copper
Zinc supports immune function and cellular growth. Research has linked low zinc levels with adverse pregnancy outcomes such as preterm birth, low birth weight, and impaired fetal growth in certain populations. Nuts, seeds, legumes, and whole grains are rich dietary sources of zinc. Copper supports iron metabolism and tissue repair and contributes to fetal growth and development. Adequate copper levels help ensure that iron is properly utilized in the body, reinforcing its role in preventing anaemia during pregnancy. Copper is naturally present in foods such as whole grains, nuts, seeds, and shellfish.
5. Docosahexaenoic Acid (DHA)
Docosahexaenoic acid, commonly known as DHA, is an omega-3 fatty acid important for brain and eye development in the baby. In diets where fish intake is limited, DHA consumption may be lower, and dietary patterns are often assessed before supplementation is considered.
A balanced diet remains central to maternal health. However, pregnancy also places increased nutritional requirements on the body. Doctor-guided supplementation helps bridge gaps that diet alone may not fully address. Maternal nutrition works best when it is steady and informed. A holistic outlook towards micronutrients and addressing deficiencies in time supports better health for mother and child, during the first 1000 days and beyond.
