That's interesting, so you've used it for 2.5 months daily and have had no diminishing effects?It seemed that way for me. I waited 3 years to take Thyroid. Glad I waited AND glad I started. I also supplement with red light in the evening a few times a week so I do not feel a need for thyroid 3 times a day. I take it 2 times a day with breakfast and lunch. Been using @LifeGivingStore’s products LOVE them
