Why Protein Matters More Than Ever?

When you’re pregnant, your protein needs increase—not only for muscle repair, but for building the tissues and organs of your baby—they even create a working circulatory system and tiny fingernails! Recommended intake can be approximately 50 grams per day, but it can jump from 50g to 70 to 100 grams/day during pregnancy, depending on trimester, body weight, and activity level.

But the downside—nausea, fatigue, and changing taste buds can make whole-food protein sources challenging to find—especially satisfactory resources like meat, fish, eggs, or dairy. These factors may make protein powders very desirable for you; but are they beneficial?

What the Research Says: Protein, Pregnancy & Safety

1. Protein Needs During Pregnancy: How Much Protein Is Enough?

The Institute of Medicine states protein intake recommendations increase from 0.8 g/kg/day during pregnancy to an average estimate of 1.1 g/kg/day for the second and third trimester of pregnancy (instead of using grams for mass, it may be easier to approximate it as about 71 grams/day on average).

Many women will struggle to meet their needs of increased protein needs from food alone, especially in early pregnancy, as they may experience nausea and aversions to many food items. For some women, protein supplementation may have been required or suggested by their medical provider.

2. Supplementation: Helpful or Harmful?

Maternal & Child Nutrition published a systematic review that indicates protein-energy supplementation for undernourished pregnant women is associated with improved birth weight and a decreased risk of being small-for-gestational-age.

But, high protein intake – especially with protein supplements in women who are in an adequate protein intake-is negatively associated with fetal growth through altered nitrogen imbalance and decreased glucose availability.

Take away message? Supplementation may be good in some circumstances, but it is not one-size-fits-all. Always speak with your gynaecologist or prenatal dietitian before adding any protein powder.

How to Supplement Smartly?

If your healthcare provider okays your protein powder use for your current eating style, here are some tips to squeeze more juice from your protein powder.

• Use one serving per day unless your healthcare consultant advises otherwise.
• Mix it with whole foods like fruits, oats, nut butters, or seeds to increase nutrient density
• Do not choose 'diet' or 'slim blends', which often have appetite suppressants or laxatives
• Do not choose powders with added herbs or adaptogens unless specially recommended during pregnancy.
• Keep track of your total protein intake from all sources (food + supplements + prenatal vitamins etc) And, most importantly, don't just read the label, investigate the ingredients like a detective (for your health).
•  If you do not recognize the ingredient, or can't pronounce it, ask your healthcare provider before you supplement.

Protein powders can be an easy way to aid parents in getting proper prenatal nutrition, only when being mindful and taken under medical guidance. Remember, we aren't behind macros; it is about completely nourishing our bodies and babies.

When you are nourishing two bodies, transparency is not optional; it is essential!

Pregnancy is a time of heightened awareness; when you grab for a supplement, grab for it wisely and always with an expert involved…

Every ingredient you select is a message to your body and your baby. Choose to make it one of nourishment and not of noise…
