- Before opening, store green powders in a cool, dark place. They can generally last around two years unopened.
- Once opened, store in the refrigerator. Sunlight and moisture can negatively impact the quality of green powders.
- It is best practice not to consume green powders after their expiration date.
Green powders can be a great addition to an already healthy diet and be added into things like smoothies, pasta sauces or casseroles.
Green powders have a variety of different benefits, including supporting the immune system, providing energy and improving sleep or recovery.
Let’s look at the best ways to store green powders to maximize their freshness, flavor and vitamin and mineral content.
How To Store Green Powders
The best way to store an unopened bottle of greens powder is to store it in a cool, dark, dry place.
One study looked at the thiamine, vitamin C, and beta-carotene content of dehydrated vegetables under cool, dark, vacuum-packed conditions. The vegetables they used in this study were garlic, carrots, potatoes, onions, and carrots. (Source)
They looked at the vitamin content at 3, 6, 9, and 12 months. They found the highest preservation of nutrients at 3 months, with about 90% retention. They found between 80-90% retention at 6 months, and around 80% or lower, even down to 40% at 12 months.
Generally, green powders can have a shelf life of around two years. It might be best practice to not purchase two years of green powders in advance, however.
If you are an avid green powder drinker, keeping a six-month supply on hand maximum at a time can help assure you have a fresher product.

How Long Do Green Powders Last In The Refrigerator?
You should refrigerate green powders once they are opened for maximum freshness and flavor. (Source)
For example, Supergreen Tonik is recommended to refrigerate after opening and consumed within 3 months after opening.
You do not need to take the green powder out of the bottle that it already came in.
Just about all of the time, the bottle will already be suitable for storing the green powder for maximum freshness and flavor.
The manufacturers and designers of the product design most containers that way to keep their product as fresh as possible for the consumers.
If for some reason the bottle does not already have an air-tight, secure-fitting container or the original one becomes damaged, it would be best to use something like a mason jar or glass container with lids that have clamps would be a good option.
Some green powders also contain probiotics, in which live probiotics need to be refrigerated as well and will not survive past 120 degrees Fahrenheit. (Source)
For whatever reason, if you cannot refrigerate your green powder, keep them in a dark container in which light cannot penetrate through.
Assuring there is no moisture in your green powder container is important too, this could speed up the spoiling process.
This makes sense because fresh vegetables and fruit like lettuce or strawberries often go bad quite quickly. They have a higher moisture content, and enzymatic reactions in fresh vegetables occur when left too long, even in the refrigerator.
Do Green Powders Expire?
Every food product has a sell-by, expiry, or best-if-used-by date. Supplements always have an expiration date or best-if-used-by date too.
A “best if used by” date indicates the last day a product will be at its maximum quality. It is not a safety date but indicates the product may not be of the highest potency or optimal flavor.
An “expiration date” indicates the last day a product is safe to consume. Consuming a product after this date would pose a health risk, and the food product or supplement should be discarded and not consumed.
All in all, yes, green powders can expire. Check the bottle for the “best if used by” date and consumers should try to use the green powder before this date.
Once you get in a groove and start to consume your green powder at an optimal time for your lifestyle, you will likely find that you have finished the greens powder much before the best if used-by date anyways.
For example, some people prefer taking green powders before or during breakfast to get their day started, just like some people choose to have a cup of coffee or tea in the morning.
Have you ever opened a bag of chips and the crunch just wasn’t right, even well before the best-by date?
Or have you taken milk out of the fridge and upon opening, found a rancid smell?
The same thing goes for green powders.
If there is any funky smell, color change or moisture in the bottle after or even before the best if used by date of an opened bottle of green powders it is best practice to throw it away and start a new bottle to assure your health and safety.
It is important to store all food products including green powders and other supplements properly to assure maximum freshness, flavor and nutrition content. Not only that, but badly spoiled fresh food can post a health risk.
Green powders can last a lot longer than fresh fruits and vegetables, so it is also a great way to get your vitamins and minerals in if you aren’t able to have access to fresh produce that day.
Oftentimes green powder users find that taking the green powders daily provides the best benefit, so there typically is no worry about using their green powders before the best-if-used-by date.
Otherwise, this article was hopefully useful to provide some insight on how to store and preserve green powders.
It is important to speak with your physician before adding any nutrition supplements into your diet and lifestyle regimen as some supplements may interact with certain pharmaceutical medications.
