Overall Opinion:

Overall, at 2.5 out of 5 stars, Gaia Source Probiotic 30 Billion is just an average probiotic.

I really just wasn’t that impressed with anything this probiotic had to offer.

I do like that the capsules use a delayed release formula, which may help the cells survive in your system.

Also, their website says that this probiotic is suitable for vegetarians.

That’s a perk and I like when companies are able to do this.

But that’s basically all I really like about this probiotic.

So, now for what I don’t like…

The directions say to take 2 capsules daily, 1 in the morning and 1 in the evening.

I like it better when it’s just one and done.

Also, the capsules are a bit chunky and may be hard for some people to swallow.

The cells are only guaranteed at the time of manufacture and it says to keep them refrigerated to maintain potency.

This makes it not as stable or convenient to use since you have to worry about refrigeration and if your cells are even alive.

The capsules aren’t allergy friendly because they contain milk and rice flour.

Gaia Source Probiotic 30 Billion has 15 different strains and 30 billion cells (as the name suggests).

This makes it pretty potent and sometimes when too many cells and strains are used, they compete with each other and can lead to negative side effects.

Also, this probiotic is only meant for adults and isn’t safe for kids.

One last note is that this company and website just seemed a little off.

There wasn’t much information on the website, 25% of the links were broken, and I couldn’t find any sort of guarantee.

Overall, at 2.5 out of 5 stars, Gaia Source Probiotic 30 Billion is just an average probiotic because it’s suitable for vegetarians and uses a delayed release formula but it’s not allergy friendly, isn’t convenient, uses too many cells and strains, and isn’t safe for kids.

The Details:

Ingredients/Strain Profile

Gaia Source Probiotic 30 Billion contains 30 billion cells in 15 probiotic strains.

Of note, I like the inclusion of Lactobacillus acidophilus in the strain profile.

This strain is one of my personal favorites and is one of the most commonly used strains in probiotics.

Lactobacillus acidophilus has been studied to show potential relief from the symptoms that come along with Crohn’s disease, Irritable Bowel Syndrome (IBS), and gut dysbiosis.

This strain may also help maintain a strong immune system, prevent traveler’s diarrhea, treat yeast infections, and lower the frequency of urinary tract infections (UTIs).

Gaia Source Probiotic 30 Billion uses 2 strains that I don’t particularly like.

One is Lactobacillus casei.

This strain has been shown to be rather aggressive and can overrun the “good” bacteria.

We don’t want this!

We want to keep as many friendly bacteria as we can.

The second strain I don’t like is Bacillus coagulans.

I don’t like this strain because it can create spores in the body, which can lead to side effects in some people.

Personally, I tend to see the most noticeable negative side effects when these 2 strains are used.

Allergy Concerns

Gaia Source Probiotic 30 Billion has some allergy concerns.

The capsules contain MILK and RICE FLOUR.

Milk is a huge problem for so many people.

Also, some of those with sensitive stomachs or digestive disorders have trouble with rice.

This product also doesn’t list anything about wheat, nuts, eggs, etc.

So if you’re really allergic to any of those, maybe be careful with this one.

The other ingredients include:  vegetable cellulose, vegetable magnesium stearate, and silica.


For 60 capsules, lasting 1 month, it costs $24.99.

When you break it down, it ends up being $0.83 a day to take this probiotic.

That’s about average for a probiotic, maybe on the higher end, though.

It’s a decent value for the price but I do think there are much better products out there for your money.

Side Effects

I definitely saw some side effects when taking this probiotic.

I experienced some belly pain and bloating.

This wasn’t fun at all.

30 billion cells and 15 strains is rather potent.

Also, it contains milk and rice flour, which may lead to some additional side effects if you’re sensitive to either.


Unfortunately, I couldn’t find any sort of money back guarantee for Gaia Source Probiotic 30 Billion.

There isn’t a ton of information on the Gaia Source website in general and some of the links are broken.

That’s a let down.

You might be able to get a refund if you bought the probiotic from, which seems to be the main way that Gaia Source ships their products.
