  • The probiotic capsules can be pulled apart and the contents sprinkled onto cool food, mixed in a cool drink or swallowed whole.
  • If you are taking antibiotics, take 4 capsules daily, ideally at a different time of the day from the antibiotics. Continue taking for at least 2 weeks after completion of the antibiotic course.

Some of the positive reviews from verified purchasers said:

“This has helped, (not cured) my daughters eczema on the back of her legs, she's 11. It was a noticeable difference when we started using it within a day. It's still there, but when we use this at meals, it does help.” – 1/13/16

“Best probiotic I've ever used. Bought these for my son who has GI issues. He's been using for 3 months now and anytime he has diarrhea we up the dose and he's better by the next day. I'm a believer! Would recommend to everyone. I started taking them and giving to all other members of our family.” – 1/1/16

“Immediate results, very pleased. I take mine with a meal. Small capsules, that are easy to swallow…” – 11/25/15

“I was on 1500mg of antibiotics a day that was making me so sick. Added this, twice a day, and I was no longer sick. I cannot say enough great things about it. Highly recommend!!!” – 11/9/15

Some of the negative reviews from verified purchasers said:

“These probiotics definitely did not sit well with me, I've tried them twice now and both times they've caused stomach cramping, diarrhea, and just general queasiness…” – 12/22/15

“my skin felt itchie and the skin behind my ears cracked after using this product.” – 11/4/15

“orded this for my family, and it has been doing it's job well. However, I mostly wanted it for my three year old son. We are on the GAPS diet, working to heal his GUT from a severe casein allergy. He vomits, get's diarrhea, and terrible rashes when he has milk (even sheep and goats milk, too). We gave him very small amounts of Bio Kult to get started, but almost immediately he developed a rash on his chest and back and bottom and his stools became very loose.” – 1/24/15

“I have an overactive immune system with numerous allergies and this was recommended for this problem. It actually made my symptoms worse. A lot of itching at different places on my body and nasal membranes swelled to the point where I could not breathe through my nose. So instead of helping me it exacerbated the problem.” 12/20/14

What are the Cons of Bio-Kult Advanced Multi-Strain Formula?

The cons of this probiotic supplement as I see them are few:

  • Only the total CFU is given. You don't know how much of each species is present so it is impossible to say if this supplement contains the bacteria in amounts equal to the studied amounts and if it should perform like the supplement used in studies and trials.
  • The bacteria are grown on soy and dairy and may contain traces of those allergens (allergy alert!)
  • Compared to other multi-species probiotic supplements, this one contains a lower number of total CFU of at least 2 billion per capsule. However, the study trials were conducted with less than that.
