I only take Lectin Shield when I can't avoid foods containing lectins. In fairness to their survey, it's difficult to feel a difference compared to if I took it regularly. I would take it every day and probably should since it's so difficult to find lectin-free foods. Instead, my strategy in keeping within my budget, I take their Vital Reds regularly and soon will be buying their probiotics and PrebioThrive supplements and will take it regularly.
Bottom Line: Yes, I would recommend this to a friend
