Bio-K+ is my go-to when I travel for making sure my immune and my gut health is in check

In 2012, Bio-K saved my life!  I had hepatitis C and had to do four months of chemotherapy... it destroyed my immune system and my bacteria.  My gastrologist recommended Bio-K and it was a godsend!

It has been our staple during these unprecedented times to keep our guts healthy and our immune system strong. I have recently discovered your peach and turmeric vegan option. You have outdone yourselves. It is by far the most delicious yet!

The first week I started taking the product, I felt an immediate improvement in my digestion and energy levels. The ashwagandha also helps me cope with stressful weeks. I will definitely buy again.

The Bio-K+ Probiotic Supplement includes 20 capsules that can be taken once per day to maintain normal bowel habits or twice per day when experiencing abdominal discomfort. The capsules are easy to swallow and help when I feel bloated.

I've been using Bio K+ Immune Health as part of my overall health and wellness plan. Given Bio K's reputation, I had high hopes, and this product definitely delivers.I've noticed an improvement in my overall well-being since incorporating these probiotics into my daily routine. The combination of probiotic strains and Wellmune seems to be a powerful duo for supporting both digestive and immune health.I appreciate that the product is vegan, making it easy to include in my plant-based lifestyle. I'll continue to use Bio K+ and would recommend it to anyone looking to boost their immune system and gut health.

I call this one All-in-One, a Probiotic that supports your digestive system, promotes better sleep along with supporting occasional stress. There’s nothing else better out there in the market. Not only my gut has been regulated, my sleep has improved and I’ve noticed lower stress levels. I would not go back to any other probiotic out there. Bio-K+ Extra has a unique formula that is clinically supported, contains 25 billion CFU and 125 mg of Sensoril Ashwagandha that is from leaf & root extract for maximum efficacy.
