This study shows that candida can develop resistance to lactoferrin. So do you think lactoferrin is more valued for its iron-binding qualities and immune enhancing qualities rather than its anti-fungal qualities?
Long-term benefits are more likely going to be in the area of supporting the immune system. I've heard of one person who had great results from using it orally for thrush, in conjunction with antifungals.
Thank you for the card. That was a very kind gesture and a nice surprise to receive in the mail. Best wishes to you throughout the New Year! God bless.
