I've also read that biotin utilization may be blocked some (not 100%) by lipoic acid use.
So I am ordering it too, from Puritan's this go round. This is the longest I've used lipoic acid.... my previous attempts were brief, because it didn't work= the older version ALA.
Biotin is also blocked by uncooked egg whites, and sometimes my boiled eggs are a bit soft and runny... not good for biotin I guess?
