The 4 Best Refrigerated Probiotics

Probiotics have become so popular in recent years, you'd be hard-pressed to find any wellness guru not taking them in some form or another. But finding just the right one for you can be hard, especially since there are both shelf-stable probiotics and ones that have to be refrigerated. While both can be effective if they're stored properly, the best refrigerated probiotics will reliably deliver the goods (aka healthy bacteria) — no matter what climate you live in — so that you can reap all of their health benefits.

Why Refrigerated Probiotics

Chances are, if you're reading this, you've already jumped on the probiotics bandwagon, but in case you need further convincing, studies have shown that probiotics can help improve immunity, aid weight loss, and even help reduce anxiety. But why should you choose a probiotic that needs to be refrigerated over one that's shelf stable? Patricia Bannan, MS, RDN, told Well + Good that probiotics are "naturally sensitive to heat and moisture," so if you live in a particularly warm or humid climate, opting for refrigerated probiotics is a good way to ensure that the key microorganisms inside don't perish.

What's more, non-refrigerated probiotics require that you follow the storage instructions to a tee. For example, if you remove the pills from their original packaging before you're ready to use them (i.e. put them in a pill box), they lose their effectiveness, according to Ilyse Schapiro, MS, RD, CDN, in an interview with Bustle.

Certain Probiotics Have Specific Benefits

So, now that you've decided that refrigerated probiotics are right for you, it's time to zero in on what particular benefits you want the supplement to have. That's because certain bacteria strains are particularly good for specific health issues. The probiotics in this roundup were selected because they contain the bacteria strains supported by medical studies and recommended by Schapiro, a certified dietitian/nutritionist.

With all that in mind, it's time to find the right probiotic for you. The options below are all highly rated on Amazon, with hundreds of positive reviews.

In just one month, I lost 2 pounds through the product alone. I did not exercise this past month and I have not been eating healthy - I still lost weight.

I not only have some family members taking these now but also other coworkers."
