@pcjaparis I looked this product up on the internet. People should be aware of the magnesium citrate ingredient, which can be detrimental to some health conditions, including CKD. Also, I note the medical review of the product is from an obstetrician/gynecologist with no mention of nutrition education. This, for me, is a big red flag.

Your endocrinolgist and nephrologist would be good sources to ask the questions about using SuperBeets in your own individual case, as they have the best knowledge of your situation. What may look good on the surface may not be a good fit for you. In my experience, fresh food is always best when possible.
