Protein Powder Tastes Bad

Why Does My Protein Powder Taste so Bad?

Protein powder often gets a bad rap for its taste.

Many people complain that it is chalky, gritty, bitter, or way too sweet.

If you want to learn why protein powder tastes the way it does, you have come to the right place.

Here are the top reasons why protein powder tastes so bad:

Protein Concentrates and Isolates

Most protein powders are made with protein concentrates and isolates, which have been stripped of everything but the protein, including the fats and carbs.

Fats and carbs are what makes food taste good, and without them protein powder tastes dry or chalky.

Insoluble Fiber

Many plant-based protein powders have a gritty texture due to their insoluble fiber content.

Insoluble fiber, because it does not dissolve in water, has a rough or sandy mouthfeel.

Artificial Sweeteners and Stevia

Many protein powders are sweetened with either artificial sweeteners (sucralose, acesulfame potassium, etc.), which activate bitter taste receptors in addition to sweet taste receptors (J Neurosci, 2004).

Stevia also activates bitter taste receptors, leading to a lingering metallic or licorice-like aftertaste.

It is worth adding that sugar substitutes are also hundreds of times sweeter than sugar, which makes it easy to overdo it.

Artificial and Natural Flavors

Many protein powders contain artificial and/or natural flavors, which do not always mimic the flavor of real food.

This can result in an unpleasant, chemical aftertaste.

How Do I Make My Protein Powder Taste Good?

Everyone who has shopped around for protein powder has found themselves stuck with a big container of protein powder they do not like.

If this is you, and you are not willing to pour fifty bucks down the drain, here are 5 ways to make your protein powder taste better:

  1. Protein powder tastes better when mixed with milk (including dairy-free milk) than when mixed with water. If you do not like how your protein shake tastes, and you mix it with water, switch to milk.
  2. If your protein shake is too gritty, make sure you are using a good blender, Electric Mixer or Shaker Bottle (with a whisk).
  3. If your protein shake is too watery, add ice cubes or a frozen banana. As long as you have a good blender, it will thicken your shake.
  4. If your protein shake is too sweet, try adding something bitter like unsweetened cocoa powder.
  5. Try adding your protein powder to oatmeal, yogurt, or other recipes to mask off-flavors.

And if despite your best efforts you simply cannot make your protein powder taste good, consider switching brands.

Frequently asked questions

Who is Drink Wholesome for?

Drink Wholesome makes minimally-processed protein powder for sensitive stomachs. Because our protein powder is additive, dairy, and gluten-free and made from a short list of simple ingredients, it’s a great option for people with lactose intolerance, IBS, GERD, and SIBO.

Why is Drink Wholesome easy to digest?

No Dairy 

Drink Wholesome is made without whey and casein, which often contain lactose, a sugar most people can’t fully digest. Some caseins also release a bioactive peptide during digestion that has been linked to digestive issues in some individuals.

No Additives

Drink Wholesome is made without food additives. Regularly eating certain emulsifiers, thickeners, and other ultra-processed additives can contribute to gut dysbiosis, which has been linked to chronic digestive issues.

Whole Food Protein

Other protein powders are made from ultra-processed protein concentrates and isolates, which have been mechanically and/or chemically stripped of non-protein components that promote digestion. Drink Wholesome, on the other hand, is made from whole food protein sources, which might be more gut-friendly.

Collagen vs egg white vs almond protein powder?

We make three types of minimally-processed Protein Powder for sensitive stomachs: Collagen Protein Powder, Egg White Protein Powder, and Vegan Almond Protein Powder. As long as you eat a balanced diet, any type of protein powder can help you meet your protein needs. So just pick the type that best suits your personal preferences.
