I have really been beating my kidneys up over awhile. Started to get that dull back pain letting me know they was stressed. I remember Tanner Tattered recommending these specifically and trust his judgement. He researches everything and doesn't just push products like the rest of industry... well... almost 2 weeks in and my faint kidney pain is less and less each passing day. I am very excited to see my next few blood work tests as I feel I found another staple in my daily supps. Easy to swallow, no bad after tastes or yucky burps. The price is very fair. Shipping time was ahead of schedule after order was processed. Very satisfied.
