How Long Does Protein Powder Last?

One question in everyone’s mind is if protein powder loses quality and potency quickly once opened?

With so many different brands and types of protein powder formulations available in the market, it can be challenging to know just how long you should keep it before it expires.

The shelf life of protein powder depends on various factors, such as the type of protein powder you have, storage conditions, and the quality of packaging.

Here’s a little detailed information on how long different protein powders can last before they get spoiled.

  • Milk-based protein powder: They tend to have a shorter shelf-life. If sealed properly, they can last around 12 months in high and 18 months in low temperatures.
  • Plant-based protein powders: They include plant products like rice, peas, soy, and hemp, that usually have a longer shelf life. When properly stored, plant-based protein should last 12-24 months.

However, almost all protein powders are low-moisture foods, so they are less prone to general bacteria growth.

Does Protein Powder Expire?

While the expiration dates on food are often associated with safety, manufacturers will generally provide expiration dates as a guideline for when the powder’s potency, taste, and texture may start to deteriorate.

In general, the ingredients of the protein powder determine its expiration date. Many preservatives in the protein powder, such as lecithin, maltodextrin, or salt, help extend their shelf life. Without any additives, the protein content of protein powder degrades with age.

Generally, the factors that can spoil the food are-

  • Moisture
  • Heat
  • Bacteria
  • Fungi
  • Oxygen

If the protein powder is correctly stored in a cool and dry place without these things affecting it, it can last for months and even beyond the expiry date.

On the contrary, if the protein powder has been stored in a warm and humid environment, it is not recommended to consume. If the color and texture of the protein powder change, it is not considered safe to drink.

Is It Safe to Take Expired Protein Powder? 

It is essential to keep in mind that the expiration or “use by” dates are usually not indicators of safety, but rather to ensure the quality. These dates do not tell when the protein powder will go rancid.

Consuming the protein powder soon after its expiration date is mostly safe if the product has been stored appropriately. However, with age, protein powders can lose protein content. If you consume protein powder after its expiration date, it might not be the best quality and you won’t be able to reap maximum benefits.

An amino acid in the protein, called lysine, that helps build muscles, can break down over time through a process known as the Maillard reaction. When the lysine breaks down, it makes the protein less effective.

An extended shelf-life test is a method to measure and estimate the stability of a product by storing it under stressful conditions like high temperature and humidity.

How to Detect an Expired Protein Powder?

If protein powder has gone wrong, it will have many signs, just like other spoiled foods, such as:

  • Clumping
  • Mold growth
  • Change in color
  • Rancid smell
  • Tastes bitter

How Do You Store Protein Powder and Maintain Its Quality for Long?

  • Protein powder should be stored in a cool, dry, and dark place. It is best stored at a temperature around 70 degrees F.
  • Avoid direct sunlight or heat exposure, as sunlight can degrade powder quality.
  • Once you open the package, store it in the fridge to increase its shelf life.
  • Keep it securely in an air-tight container after each use to prevent air and moisture from getting in.
  • Please keep it away from sources of moisture, such as the sink and dishwasher.
  • Make sure to use a dry scoop or spoon for powder, as getting water into the container can spur mold growth.

How to Use Protein Powder Before It Expires?

Protein shakes and smoothies are not the only way to consume protein powder. Protein powder also mixes well in a variety of healthy recipes.

  • Proffee, which is a mix of protein powder and coffee
  • Protein powder in oatmeal
  • Protein powder in waffle and pancakes
  • Protein powder in quinoa breakfast bowl

Sneaking a scoop of protein powder into your favorite food is an easy and nutritional way to use the protein powder before they go bad.


Protein powders are a popular supplement that comes from a variety of animals and plant-based sources. Adding protein powder to the diet is an excellent way to maintain good health and increase your protein intake. 

So, if you wonder how long protein powder lasts, ensure that with proper storage it will last for a longer period of time.
