> In your second trimester, as your baby's growth accelerates, your body's protein needs increase significantly to support their rapid development.

During your second trimester, as your baby begins a period of rapid growth and development, your body's need for protein increases significantly to support both their expanding tissues and your own physiological changes. This period marks a noticeable shift from the foundational development of the first trimester, requiring a more substantial intake of this crucial macronutrient.

Evidence suggests that daily protein needs for pregnant individuals increase from approximately 46 grams to around 71 grams, representing about a 25-gram daily increase. This additional protein is essential for building new cells, tissues, and organs for your baby, as well as supporting the growth of your uterus, placenta, and increased blood volume. While protein deficiency is uncommon in high-income countries, understanding these increased needs allows you to make informed decisions about your dietary choices. Just as you might consider how other nutrients like [Biotin (B7) in the second trimester](/nutrition/biotin-b7-trimester-2) play a role in overall wellness during this time, protein forms a core part of your nutritional foundation.

When considering protein sources, both animal and plant-based options offer valuable contributions. Animal proteins, such as eggs, fish, lean meats, and dairy, are considered 'complete' proteins, providing all essential amino acids in a single food. Eggs are particularly noteworthy, offering not only protein but also choline, a nutrient often deficient in many diets, which is vital for fetal brain development. For those exploring plant-based nutrition, options like legumes, soy, quinoa, and hemp are excellent sources. It's helpful to know that the long-held belief about needing to combine specific plant proteins at every meal to achieve 'completeness' has been debunked; variety across your day is what truly matters. This approach to balanced nutrition is similar to how we might consider supporting gut health with [Probiotics in the first trimester](/nutrition/probiotics-trimester-1) to lay a strong foundation for nutrient absorption.

While meeting these increased protein needs is important, balance remains key. Research indicates that excessive protein intake, defined as more than 25% of total calories, has been associated with adverse outcomes in some studies. This highlights the importance of a well-rounded diet rather than focusing on any single macronutrient in isolation. As a birth doula, I emphasize exploring options and making choices that feel supportive for you. For example, ensuring adequate protein intake can complement other aspects of your wellness, much like considering [Probiotics in the second trimester](/nutrition/probiotics-trimester-2) for digestive comfort.
