It is well known that protein plays a key role in the growth and development of the fetus. While protein can be availed from several natural sources, some women may consider using protein powders during pregnancy to meet their additional protein needs. However, they may have some questions regarding the safety of using protein powders.
Read this post as we tell you about the recommended protein intake levels in pregnancy, the natural sources of protein for pregnant women, and whether protein powders are safe and necessary for pregnant women.
Why Do You Need Protein During Pregnancy?
Protein is considered highly important for expecting moms as it aids in building tissues for both the mother and the baby. Adequate protein helps in general growth and development through all the stages of pregnancy, and more so during the third trimester (1).
Protein also builds other tissues, muscles, antibodies, hormones, and enzymes in the baby and mother. Moreover, extra protein helps in amniotic fluid production and improves blood volume as well (2).
Pregnant women should make sure they are consuming adequate protein for a healthy outcome, as too low or too high quantity might lead to certain complications.
How Much Protein is Required When Pregnant?
Doctors recommend a daily intake of approximately 71 grams of protein during pregnancy. The limits can go up to 90 grams a day during the second and third trimesters of pregnancy. In all, the protein requirement increases by around 25 grams per day for pregnant women (3) (4).
A few good sources of protein include nuts, beans, soy, chia seeds, peas, eggs, poultry, fish, and lean meat. Vegetarians and others who are lactose intolerant may not get enough protein from these sources and may have to rely on protein powders to meet the recommended daily intake of protein during pregnancy.
Are Protein Powders Safe During Pregnancy?
No. Protein powders are usually not recommended for pregnant women because they contain several ingredients that might be harmful to the baby’s health. Protein powders come under the supplements category, and the FDA has left the evaluation of the product’s safety and labeling at the discretion of the manufacturers (5).
For instance, certain ingredients that are generally considered safe during pregnancy might not be safe when they are mixed with other compounds in the supplement. Protein powders are also not considered safe during pregnancy for other reasons that we discuss next.
Why Are Protein Powders Not Recommended During Pregnancy?
Here are some reasons why protein powders are not good for pregnant women.
- Protein powders may contain certain additives such as extra vitamins, caffeine, creatine, and fillers/flavoring agents that may not be good for pregnant women. For a safe pregnancy, you should avoid these powders.
- Most of the protein powders available in the market are milk-based and may cause gastrointestinal problems for women who are lactose intolerant or have dairy allergies (5).
- A lot of artificial sweeteners are added to protein powders. Although there is no proper evidence showing any adverse effects of sugar substitutes during pregnancy, they should be consumed in moderation. Some sweeteners you need to avoid are acesulfame potassium and thaumatin. Also, additional sugar content in protein powder may result in weight gain and increased blood sugar levels (5).(6).
- Some ingredients used in protein powders do fall under the GRAS or generally recognized as a safe category. However, when used in high amounts, these ingredients can have certain adverse effects during pregnancy (7). Hence, make sure you do your research before buying any protein powders from the market.
- Heavy metals such as arsenic, lead, and cadmium are also found in some protein powders that are available in the market. These might increase certain health risks for the baby and mother and should be avoided (8).
Before picking up protein powder that you think is safe for you, talk to your doctor and get their opinion. If the doctor thinks it is a bad idea, you can look at other sources of protein that are safer for you and the baby.
What Are The Other Ways To Get Protein During Pregnancy?
According to the USDA Food Composition Databases for Standard Reference, the following are good sources of protein (9).
Food | Protein value per 100g |
---|---|
Peanut butter | 24g (10) |
Chicken | 30.39g |
Eggs | 12.56g(11) |
Milk (dry, nonfat, regular) | 36.16 |
Fish (Salmon/Tuna) | 24-25g |
Yogurt (plain/low fat) | 5.25g |
Grains/Mixed-grain (oats/corn/granola) | 6-11g |
Tofu | 17.27g |
Frequently Asked Questions
1. What happens if I don’t eat enough protein during pregnancy?
Inadequate protein intake during pregnancy may lead to intrauterine growth restriction, pre-eclampsia, preterm labor, or excessive fat deposition in the baby (12).
2. Can too much protein cause miscarriage?
Yes, excessive protein intake may lead to fetal death or loss of pregnancy (12).
Protein is essential for both the mother and the infant in developing tissues. However, consuming protein powder during pregnancy is not considered safe since it contains chemicals and artificial sweeteners harmful to pregnant moms and newborns. However, not all protein powders are dangerous, so talk to your doctor about which ones are safe to consume during pregnancy. Alternatively, you may fulfill your protein needs by eating protein-rich foods such as nuts, beans, soy, chia seeds, peas, eggs, and other foods. It’s important not to take too much of it because it can cause complications.
