A 14-strain, 20-billion-CFU daily probiotic — here's what it does well and what to know before you buy.

What it is

MegaFlora is a daily probiotic from MegaFood, a US brand known for whole-food-based supplements. Each capsule contains 20 billion CFUs (colony-forming units) from 14 strains, mostly from the Lactobacillus and Bifidobacterium families — the two groups most commonly studied for gut health.

What’s inside

  • 14 probiotic strains, including L. acidophilus, L. casei and several Bifidobacterium strains
  • 20 billion CFUs per capsule
  • A cellulose capsule with cellulose, silica and L-leucine as other ingredients

It’s vegan, dairy-free, gluten-free and non-GMO. The label doesn’t list how much of each individual strain is included.

What it’s for

People take MegaFlora for everyday digestive balance and general gut support, which also plays a role in immune health. A multi-strain formula like this is a sensible all-rounder rather than a targeted product for a specific issue.

How to use it

Take one capsule daily with a meal, and keep the bottle in the refrigerator.

Things to keep in mind

The capsule has no delayed-release coating, so some bacteria may not survive stomach acid. There are no prebiotics (the fiber probiotics feed on), and refrigeration makes it less travel-friendly. MegaFood doesn’t advertise a money-back guarantee, so check the retailer’s return policy.

The bottom line

A solid, affordable multi-strain probiotic from a trusted brand. If you want something shelf-stable or with a targeted delivery capsule, you may prefer an alternative — but as a simple daily probiotic, it does the job.

What I like

  • Wide range of Lactobacillus and Bifidobacterium strains
  • Simple daily dose
  • Affordable per day

Keep in mind

  • Needs to stay refrigerated
  • No delayed-release capsule
  • No prebiotics included
  • Individual strain amounts not listed

Common questions

Yes. MegaFlora should be refrigerated to keep the bacteria alive, which makes it less convenient for travel.

Some people notice mild bloating or loose stools in the first few days. This usually settles as your body adjusts.
