I am hypothyroid and have been taking bovine glandular extract for the last 2 months. I feel well, but my resting pulse is 94 and I find it difficult to sleep with a heart rate that high. I have the same problem when I take synthetic levothyroxine, that is why I switched to bovine extract, hoping it would be better. I divide the capsule into 4 equal doses, because if I take it all at once my heart just hammers away all day. Can anybody help.
