Kristina at Optimal Health Network saved me in a situation of despair. I was in distress and found their services online by Google search. Since Optimal Health Network dont ship to the country I live in, I signed up for a WhatsApp-appointment. I was unsure about the way the payment was done and also having a consultation over the phone. Everything worked just fine, all worries set aside. The advice I got has helped me immensely. I write this review a month after my appointment. From having excruciating pain and problems with digestion I am now totally fine. It is an enormous relief. Thank you Kristina!
