The Safety of Protein Powders for Pregnant Women
The safety standards of protein powders for pregnant women are very well established.
The fact that pregnancy places huge physiological stress on the body makes it necessary for women to remain nourished all throughout their term. 
The only safety concerns that arise with respect to protein powders and pregnancy are related to the additional components that may be present in a specific protein supplement. 
For instance, many protein supplements aim at performance enhancement for athletes and regular trainers, and thus, a regular post-workout protein powder will contain additional items such as important vitamins and minerals to boost muscle growth, immunity, etc.
A pregnant woman would not necessarily require such additives in the prenatal period. An unregulated intake of such supplements can be harmful to women in the course of their pregnancy.
If you are able to spot a protein powder that has undergone third-party testing especially for antenatal vitamins, unnecessary metal extracts, etc., you can surely consume that supplement to keep your body nourished and prepared for delivery.
Protein Supplement Ingredients That Pregnant Women Should Avoid
The consumption of common artificial sweeteners, like sucralose, saccharin, aspartame, etc., is usually contraindicated for most pregnant women. 
This is because artificial sweeteners are found to interfere with the functioning of the thyroid gland, which is of extreme importance during and after pregnancy.
Moreover, by altering the gut biome composition, some artificial sweeteners invariably contribute to raising the blood sugar levels rather than keeping them under control.
Plant-based powders are considered good for pregnancy, but their ingredients should always be well-researched.
A protein powder having a proprietary blend with unknown herbs in it is a certain red flag when it comes to protein powders for pregnancy. Any protein powder claiming to be 'natural and 'organic' is not always beneficial for a pregnant lady.
Therefore, to remain on the safer side, pregnant women should avoid consuming prenatal protein powders with herbs that do not have any proven benefits. 
Factors to Consider Before Buying a Protein Powder For Pregnant Women
Based on in-depth market research and responses from women who had themselves taken protein supplements at the time of pregnancy, here are some points that you should keep in mind before finalizing a protein powder.
1. The Source Is Very Important
The source of protein is important because it decides how easy or difficult it would be to digest and absorb the protein. Whey Protein powders are generally the safest option for pregnant women. 
However, if you plan to consume a plant-based protein powder, you should go for a supplement that has brown rice or pea protein. These sources are safe for pregnancy, and also provide a full range of essential amino acids.
As stated before, refrain from buying supplements with processed soy isolates.
Dairy-based proteins take a little longer to get digested. However, if you still want to go for one, you should select a 'grass-fed protein powder.
2. Good Taste and Palatable Protein Supplements
Good taste and exciting flavors are as important for pregnant women as they are for teenagers.
Like I said before, there are a whole lot of physiological changes in the body during pregnancy. Taste changes are very common in women during this period, and thus, giving them a supplement that tastes bad would not be a great idea.
Of course, you've got to take care of the fact that just for the sake of taste and flavors your supplement does not contain any added artificial sweeteners.
Some unflavored options are also quite good because their innate taste is somewhat palatable.
If you're pregnant, you must be knowing how many extra brands tend to charge just in the name of 'safe pregnancy products'.
While there is no doubt that it is better to pay for added safety than regret later, there are affordable options in the market too. You should study every option before finalizing a protein powder.
Conversely, if you're seeing a protein supplement being sold at super cheap rates, there are chances that the product quality will turn out to be dismal eventually.
The third-party testing results and other parameters to check the safety of a supplement should always be at the back of your mind.
Addressing the Controversy
The biggest controversy around protein powders for pregnancy is the lack of regulation from a competent organization like the FDA.
This way, there are chances of the unknown, and possibly harmful ingredients like mercury, BPA, etc., being present in these supplements. It is a calculated risk, but not regulation from the FDA does not mean that every brand sells unsafe protein powders.
Not having an approachable resource for understanding what is acceptable and what isn't is a problem that in a way nurtures these apprehensions.
The bottom line is that protein supplements are not unsafe for pregnant women.
However, one has to make a conscious decision of selecting a protein supplement manufactured by a reliable brand, which has a protein source that you are familiar and comfortable with. Ideally, whey protein or pea protein (plant based protein) are safe for pregnancy and can be consumed without any apprehensions.
Moreover, a supplement with a short ingredients list is always better. This means that added vitamins, minerals, caffeine, sweeteners, etc., are the real things that can harm the body during pregnancy and not protein per se.
Many doctors themselves recommend protein shakes during pregnancy, thus, you can ask your doctor for better and more reliable advice regarding supplements.
Is whey protein safe for pregnancy?
Whey protein isolates are considered the best for pregnant ladies. Ensuring that your Whey protein powder is free of any harmful additives is important for the safety of pregnant women.
Are plant based proteins beneficial during pregnancy?
Plant based proteins have lower calories and fat content than animal proteins. If taken from a healthy and reliable source, these proteins can provide excellent all-round nourishment during pregnancy.
What are some of the best protein sources for pregnant women?
Protein derived from eggs, milk, peas, brown rice, etc., is the safest for pregnant women.
So, this was my list of the best protein powders for pregnancy.
The Transparent Labs 100 % Grass-Fed Whey Protein Isolate is quite convincingly the #1 protein powder for pregnant women. It has a blend of extensively tested ingredients that are highly safe and effective.
The supplement has a short but very reliable list of ingredients, delivering an enormous amount of protein per serving with no additives at all.
Bulk Supplements Grass-Fed Whey Protein Isolate 90% is also a good option. A plain and simple powder with good amounts of protein.
