Shipping Info

We ship Monday through Wednesday, using two day premium shipping services that includes tracking.

Organic 3 probiotics are freeze-dried, so they hold up well to warm temperatures.

When temperatures exceed 75°F, we recommend our optional Cold Pack Shipper, which adds one or more ice packs (depending on the size of the order) and insulated packaging. These ice packs are not designed to stay cold during the entire shipment process, but do provide adequate protection. The ice packs may arrive warm, or even hot. This is normal and expected, but does not reduce the potency. Our Cold Pack Shipper also works well for our other products that are kept in cold storage.

If the temperature is above 95°F in your area at the time of ordering, we recommend shipping the probiotic with our optional Dry Ice Shipper. This will provide significant protection from excessive heat.

Please note: We cannot ship dry ice to a P.O. box.

We take pride in making sure your orders are handled with the utmost care, and arrive to you in a timely manner.



Product requires refrigeration for long-term storage.


Take 1 - 2 capsules daily for systemic yeast overgrowth. May be taken prior to, during or immediately following a course of antibiotics. Yeastbiotic is most effective when taken in two to three week increments followed by a break of one to two weeks.

Therapeutic probiotics such as GutPro, Primal Gut and Primal Soil may intensify Yeastbiotic's effectiveness. If you are experiencing discomfort as a result of excessive yeast die-off lower your probiotic dose. You may also lower your Yeastbiotic dose by pulling apart the capsule and taking a portion of the powder (the powder will appear white with brown specs).

Important: The supplements we carry are premium, pure and potent. Therefore, it’s critically important to start slowly, with a lower dosage than recommended. For example, a very small dose every other day, or even once a week, until you can determine how the supplement affects your body and what dose feels right for you.

Miracle Worker

This product is an absolute miracle worker. It’s great for reflux, and unlike every other S. Boulardii product out there this has no irritating prebiotic fibers or fillers to make you sick. I also had to be on two rounds of antibiotics for a bad sinus infection recently, and as long as I took a Yeastbiotic pill morning and night I had absolutely no gastrointestinal side effects from the antibiotics. I’m now repopulating my gut with some GutPro along with continuing the Yeastbiotic. This stuff is magic, I swear. It’s a fantastic product.


Hello Lesley, Thank you so much for sharing your feedback on Yeastbiotic by Organic 3 :) We're thrilled to hear that you're loving it - and that it supported your system during your two rounds of antibiotics by preventing GI side effects associated with antibiotics. Indeed, Yeastbiotic contains only the friendly yeast probiotic strain, S. Boulardii and benign fillers for encapsulation - nothing irritating and no prebiotics :) And how wonderful that you're repopulating the good bacteria in your gut with GutPro and rounding out your Yeastbiotic. We're so happy that you're feeling better and that Yeastbiotic was part of this healing :) We appreciate your support, Leslie. And we're honored to serve you! Warm regards, The Corganic Team

Yeastbiotic great after taking antibiotics

Had to take antibiotic for bronchitis so took Yeastbiotic afterwards. Did not get a yeast infection afterwards thanks to Yeastbiotic and had no stomach upset, no GI problems. Will definitely order again even just to prevent yeast infections in future.

Superb for fungal skin issues

My daughter had seborrheic dermatitis from head to toe. I knew the only way to get rid of the fungus of her skin is s boullardi. This product doesn't have fillers like others I've seen on the market. Give it at least 2 months to notice a difference.

Every time I use antibiotics I battle a yeast infection. We ordered this product and gave it a try. This worked! Finally something that works after two rounds of Diflucan that didn't work. This is my go to now and have recommended it to my doctor. Thank you for a great product!

Love This Product!

I take two of the Yeastbiotic capsules per day along with one GutPro capsule, and my body loves these probiotics! Corganic is a very clean brand and I definitely notice what a great difference it makes. I take probiotics to help keep my gut flora happy and healthy, which aids in my digestion. When my digestive system is happy so is my skin! I’ve found this product to be helpful with skin rashes, as skin is the largest detox *****. I’m thankful for the stellar products and am happy with my positive results!
