A Roman poet, Lucretius, once said, “one man’s meat is another man’s poison”. This quote translates perfectly in this context to mean “best” is relative. The best milk to mix with protein powder for me isn’t automatically the best for you because we may have different nutritional needs and goals. Continue reading this article to find the best drink for you to use in your protein shakes.

It should go without saying, if you do not want any additional calories, flavor, or significant cost then water is the right choice for you. If you want to add more nutritional value, and enhance the flavor, continue reading.

What is the best milk for protein shakes? Water, low fat milk, dairy or non-dairy? Read along as we talk about how you can optimize your protein shakes.

The best milk for protein shakes should be generally health promoting, and nutritionally balanced. That is, low in saturated fat, rich in vitamins and minerals, but with minimal added sugar. Moreover, the best milk/milk alternative for protein shakes can enrich your drink in taste and consistency.

How to Choose the Best Milk for Protein Shakes?

As mentioned, what’s best for one isn’t necessarily best for another. So let’s dig into what you should consider the healthiest milk for protein shakes before choosing your option.

1. Nutritional Value

As you keep reading, you’ll discover that the best milk alternative for protein shakes can have different nutritional value. For example, whole milk is high in saturated fat, moderate/high protein content, high calorie count, and numerous vitamins. On the other hand, almond milk has low fat, low calories, only monounsaturated fat, and is typically fortified with vitamins and minerals.

At first glance, almond milk may seem to be the healthier choice nutritionally, but if you are training intensely and trying to increase your muscle mass, the right choice may be whole milk. If the milk substitute you have access to is not fortified with things like calcium, then you may not get enough calcium in your diet without dairy. Your nutritional needs and preferences will determine your milk choice.

2. Calories

The calories will also differ depending on the fats, carbs, and protein present in each milk. If you’re looking for low calorie options, hemp, pea, or almond milk are the best options. If you are trying to increase or keep your calorie intake high, flavored milk alternatives, oat milk, or higher fat dairy milk can be good options.

3. Added Sugar

Many non-dairy alternatives add sugar and natural or artificial flavors to improve the taste. While this may be acceptable in some cases, just be aware that added sugars are adding additional ‘empty’ calories, meaning they do not have nutritional value. So maybe choose an unsweetened version to ensure you get all the benefits without the added calories. Or you can add fruit to your shake/smoothie to get more sugar and calories while also getting more vitamins, minerals and other nutrients.

4. Allergies and Lactose Intolerance

Over the years, more milk substitutes have been introduced for those with lactose intolerance or on vegetarian/vegan diets. If you experience issues with dairy products like gas, bloating, or cramps, consider trying a plant-based milk alternative like soy, which still has high quality protein like dairy. Soy and nuts are common allergens though, so hemp or oat milk may be the next best choice if you have other allergies or sensitivities.

5. Flavor

Most people would probably agree that using milk or milk alternatives will improve the flavor of your protein shake compared to using water. However, everyone has different taste preferences, and each milk has its own flavor profile. Dairy milk is creamy but does not have a strong flavor. Almond milk is less creamy and has a subtle but nutty flavor. Oat milk is possibly the creamiest of the plant based alternatives and is naturally slightly sweet, but pea and hemp milk have a dull, almost bitter taste.

6. Texture

Milk is thicker and creamier than water, but some plant based milks, like hemp and almond, are thinner than dairy milk. Nonetheless, you can get a creamy plant-based milk like soy milk, which can be as thick as its dairy counterparts.

7. Cost

Depending on what country you live in, the prices of different milks can be vastly different. For us Canadians, dairy can actually be quite expensive. If you are already using protein powder the higher protein content of dairy milk may not be worth the extra cost.
