I'm currently taking a product called: Vibrant Health - U.T. Vibrance, Crisis Intervention Formula, which suggests to take 5 grams of this product 4 times a day, so basically 20 grams a day for about 4 days. I got some digestive issues the next day after taking this product but I thought it was just fine, just a side effect of this product. I then was doing some research to see if it was still OK to take that amount of D-mannose and surprisingly I found online that it says in many health pages that high doses of D-mannose might damage the kidneys, so then I freaked out and I was trying to do my research to see what is considered a high dose on D-mannose. Good thing I have been taking this product for 2 days only.
I would think that if this product is being sold without prescription is safe to take that amount without having any permanent damage to the kidneys, but I would like to better be safe than sorry.
I couldn't find the answer so I just decided to ask here what is the maximum amount that would be considered safe for adults before it might cause kidney damage?
NOTE: I'm not looking for an advice on my condition, all I'm looking for is what is considered a high dose of D-Mannose, which many articles talk about but fail to specify what would be considered as a high dose. It says in many articles that a safe dose is between 1 and 3 grams a day, but they don't specify what would be considered a high dose. So it could be 10, 20, 30 gms a day maybe? That's what I'm trying to find out.
