Have IGA Nephropathy. Urine And Blood Test Normal. Is It Safe To Take Ceratine?
Thanks for the query.
Your son has a proven IgA nepropathy. Such nephropathy patients should restrict protein intake from all sources to 0.8gm/kg/day especially if there is protein in urine. Taking more protein can increase the proteinuria and cause progression of kidney disease.
Therefore heavy protein intake used for body building is not recommended.
There is no way to suggest how much is safe; but the basic idea is that more protein intake will drive proteinuria which is a risk factor for kidney disease progression.
Though he has no urine protein (urinary protein is nil as you say), he can undergo urine microalbuminuria test - if that is absolutely normal, the risk of disease progression is less with protein supplements. However still heavy protein intake from any source is not recommended.
Hope this helps. Any further queries are welcome.
