Be aware that most K2-mk7 is a mix of cis and trans form, where allegedly only one of them is bio-active. When LEF was questioned which theirs contains they answered, such a mix out economical reasons. So even with their mixed form, one would get a good dose of the active. Don't know what moved them to reduce it to 100 mcg again. Could just be they changed to the active only form.
With all other companies which don't disclose this important detail, one might get only 50% of actives than declared too.
