How To Tell If Protein Powder Is Bad

Does Protein Powder Work? (Spoiler: YES, but there’s a catch)

You can tell if whey protein has gone bad by simply smelling it. Rancid whey is going to smell moldy and sour. If you open a new container of whey, give it a smell and make sure it doesnt smell like spoiled milk. If it smells off, then you should throw away any unflavored portion of your supply.

If you notice mold growing on your protein powder, do not taste test it! Throw away any large containers that have been exposed to air. While there are some safe ways to determine if your protein has gone bad , you should always be cautious when consuming powder products like these due to how quickly they go rancid once theyre exposed to air or water.

These normal conditions are defined as 70°F and 35% humidity. If a protein contains additives, that can extend the shelf life for up to two years.

Unlike whey protein or casein protein, plant proteins like hemp, pea, and soy do not contain milk or dairy. The exclusion of milk ingredients eliminates significant bacterial concerns. Vegan proteins generally keep better than whey protein, with a shelf life of two years, or 24 months.

However, nearly all protein powders from whey protein to pea protein are low-moisture foods, so theyre less prone to bacterial growth in general. As long as you consume your protein powder within a few years of purchasing and store it in a place thats cool or room temperature, you probably wont have to worry about dry products like protein powder going bad.

The Risk Of Consuming Expired Whey Protein

Body Fortress Whey Protein Reviewed in 2020

The good news is that it is improbable that your expired whey protein will make you sick.

This is because your whey protein is a supplement that is low in moisture, making it an unlikely candidate for bacterial growth.

So the only risk of consuming expired whey protein is that you will not get the benefits and nutrients you were hoping for when you originally purchased the powder.

If you consume whey protein that has gone past its best by date within months or years, it is still safe for consumption, but your whey protein has lost a lot of its quality after it passed its best by date by so long.

Avid whey protein consumers state that they still enjoy their whey protein long after the expiry date but consume a significant volume of it to make up for the drop in quality.

However, this is only the case if the whey protein still seems fine for consumption.

As soon as your whey protein shows signs of contamination, it is best not to have any more of it because, although the risk of getting sick from bacteria growth is low with whey protein, it is still present.

How To Tell If Whey Protein Has Gone Bad / How To Know If Whey Protein Is Fresh

If you notice changes in your protein powder, you should be aware that in the worst scenarios, it can attract bacteria that you should not consume. Judge your container against how it looked, smelled, and tasted the day you opened it, as each type of whey protein powder can change in different ways, depending on how they are made and what they are blended with.

Foul Odor: If it begins to smell rancid, like souring milk, it has been contaminated with moisture, and there is bound to be bacteria growing in there that might upset your stomach.

Clumps: Clumps forming in your whey protein is another sign of moisture exposure. Just a drop or two of water can form these clumps, and it is recommended the entire container be tossed. Some consumers will just scoop out the clumps, but try it at your own risk.

Color: If the powder was white when you bought it, it probably has been bleached, and will turn yellow or brown when it goes bad. Whey is naturally off-white, but if it darkens, throw it out.

Cardboard taste: Whey protein may not taste great on its own when it is fresh, but it should never taste like cardboard. When it does, you know it is time to get a new tub or bag.

9 Amazing Benefits of Whey Protein | for NON bodybuilders

You can store a bag or tub of dry powder in a cool pantry for up to two years, but what if you use that protein powder in shake? How long can you leave your protein shake out and safely still drink it?

The short answer: If you mix your protein powder with your favorite liquid, youll want to consume it right away. You can probably stick a protein shake in the fridge for a few days, but if you leave the shake out in a warm or hot environment, you are not going to want to drink the contents after a few hours. So if you made a drink, set it down, but then forgot about it for a few hours, youll want to dump it and just make a new one. Wash the shaker bottle or container, and start over with a fresh protein shake.

Expiration dates on protein powder packaging are for the dry protein powder, not a protein shake. Once you mix it with other food products especially perishables like milk or produce the expiration date of the powder no longer applies.
