This product is amazing. I have been using 3 drops under the tongue 3 times a day and I have NO arthritis pain at all. I am able to walk my dog over 4 km now instead of 3 blocks. I sleep very well, no longer grind my teeth at night. I can walk down stairs one at time like a normal person. Quality of life has returned… The staff are incredibly helpful and made my decision to use this product very easy. THANK YOU!!!!
