I love this product very easy to use and makes you feel balanced and fresh. I feel like the price is very good for the product and I recommend this to anyone who promotes vaginal health.

I have been taking probiotics to help with my digestion, and this Bio K+ Vegan Probiotic supplement seems to work well. It is very easy to swallow and doesn't have any bad smell or taste. The fact that it has additional Immune Support in a single pill is a nice bonus.

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.
