There is no direct contact other than email. No in person contact via phone. Although I had been taking MB for 2 years prior to using this site, now it appears I will be paying an extra fee to a practitioner somewhere. I am mid 70’s and have studied nutrition since the 1970’s. I do not need or want any further help at this time. I will compare suppliers vs cost. One pharmacy offers sealed capsules at a bit higher dose and cost but may be more cost effective. We will see when the time comes.
