Are smoothies good after being in the fridge?

Smoothies have become an increasingly popular and convenient way to get your daily dose of fruits and vegetables. Many people make large batches of smoothies and store them in the refrigerator to have ready-to-go snacks and meals throughout the week. But how long do homemade smoothies last in the fridge? And are they still healthy and safe to drink days after being made? Let’s take a closer look at how to store smoothies and how long they stay fresh and nutrient-rich.

How Long Do Smoothies Last in the Fridge?

The shelf life of smoothies depends on several factors:

  • Ingredients used – Fresh fruits and vegetables have shorter shelf lives than frozen ingredients or powders.
  • Storage container – An airtight container will keep a smoothie fresher than a container with exposure to air.
  • Acidity level – Higher acid foods like citrus fruits and berries allow smoothies to last longer.
  • Added ingredients – Dairy, protein powders, chia seeds and nut butters can shorten smoothie shelf life.

Taking these factors into account, here are some general guidelines for homemade smoothie fridge life:

Smoothie Type Fridge Life
All frozen fruit and/or veg 3-5 days
Frozen fruit/veg with fresh greens 2-3 days
All fresh fruit and veg 24 hours
Added protein powder or nut butter 24 hours
Added dairy like yogurt 24 hours

To get the most shelf life out of your smoothie, use more frozen ingredients and less fresh produce, dairy and other perishable add-ins. Store them in an airtight container or jar, and keep refrigerated at all times. With proper storage methods, most smoothies stay good for 2-3 days.

Signs Your Smoothie Has Gone Bad

How can you tell if your refrigerated smoothie has spoiled and is no longer safe to drink? Here are some signs to watch out for:

  • Change in consistency – Smoothies will thicken up and become grainy as the ingredients start to deteriorate.
  • Separation – You’ll notice the liquids separating from the solids, with a layer of juice or water at the top.
  • Mold growth – Check closely for tiny dots of mold starting to form, especially on top.
  • Strange smell – An unpleasant or rotten odor is a clear giveaway that your smoothie has gone bad.
  • Fizzy texture – Fermentation due to extended fridge time can cause smoothies to become carbonated.
  • Discoloration – Bright green smoothies will start to fade and oxidize to an unappetizing brown.

If you notice any of these changes in a refrigerated smoothie, it’s best to err on the side of caution and throw it out. The nutrients degrade over time, and consuming spoiled smoothies can potentially make you sick.

How to Store Smoothies for Maximum Freshness

Proper storage methods are key if you want your prepped smoothies to stay fresh and last longer. Here are some tips:

  • Use freezer-safe containers – Glass jars or plastic containers with tight lids work best.
  • Fill leaving 1/2 inch of room – This prevents overflow as ingredients expand.
  • Remove excess air – Minimize oxygen exposure by squeezing out air before sealing.
  • Freeze for up to 3 months – For long-term smoothie meal prep, store in the freezer.
  • Thaw in the refrigerator – Move frozen smoothies to the fridge 1-2 days before drinking.
  • Never refreeze – Only thaw what you plan to consume within 3-5 days.
  • Use fresh ripe produce – Frozen fruit and veg have a longer shelf life than fresh.
  • Add acids – Lemon, lime, pineapple and berries help preserve.
  • Avoid dairy – Milk, yogurt and cheese shorten fridge life.

Following these simple smoothie storage rules will ensure your blended creations maintain peak texture, color, nutrients and flavor for as long as possible.

Benefits of Drinking Refrigerated Smoothies

If stored properly, smoothies that have been chilling in the fridge for a few days still retain most of their nutritional value and delicious taste. Here are some benefits of drinking refrigerated smoothies:

  • Convenience – They are ready to grab-and-go for quick nutrition.
  • Lower food waste – You use up leftover prepped smoothie batches.
  • Time saving – No need to freshly prepare smoothies every day.
  • Hunger satisfaction – The fiber keeps you full and satisfied.
  • Nutrient intake – You still get vitamins, minerals and antioxidants.
  • Hydration – The liquid content keeps your body hydrated.

As long as you consume the smoothie within the recommended 3-5 day window, a refrigerated smoothie provides very comparable health perks to a freshly made one.

Potential Risks of Drinking Spoiled Smoothies

On the other hand, drinking a smoothie that has been sitting in the fridge for too long can potentially cause negative effects. Here are some risks associated with consuming spoiled smoothies:

  • Food-borne illness – Harmful bacteria like salmonella or E. coli can grow.
  • Gastrointestinal distress – Stomach pain, nausea, vomiting or diarrhea may occur.
  • Degraded nutrients – Vitamins and antioxidants break down over time.
  • Toxic mold exposure – Some molds like penicillium can cause allergic reactions.
  • Bad taste – Unpleasant smells and texture make the smoothie unpalatable.

If a smoothie has separated, changed color, developed a slimy texture or smells sour, it’s better to be safe than sorry. Drinking rotten smoothies can make you sick, so stick to your prepared batches within the recommended 3-5 day period.

Tips for Using Up Leftover Smoothies

Don’t let old smoothies go to waste! If you have prepped smoothie batches leftover that are nearing the end of their fridge life, here are some delicious ways to use them up:

  • Add to oatmeal or yogurt for a protein and fiber boost.
  • Mix into pancake, muffin or banana bread batters.
  • Blend with ice cream for a creamy treat.
  • Freeze into popsicles for cooling snacks.
  • Mix with vodka or rum for a healthy cocktail.
  • Swirl into overnight chia pudding recipes.
  • Top your waffles or French toast at breakfast.
  • Fold into protein balls or energy bites.
  • Use as the liquid in overnight oats.

With a little creativity in the kitchen, you can repurpose old smoothies instead of dumping them down the drain. Your taste buds will thank you.


When properly stored in airtight containers and kept refrigerated, most smoothies stay fresh and safe to drink for 2-3 days. Look out for changes in color, texture, smell and consistency to determine if your smoothie has spoiled. Drink refrigerated smoothies within a 3-5 day period to get the most nutritional benefits. And try creative ways to use up smoothies that are past their prime instead of wasting them. With some simple smoothie storage strategies, you can enjoy convenient ready-made smoothies all week long.
