Biotin 5000mcg has not been shown to directly cause kidney damage when taken as a supplement. However, if you have IgAN you should:

Tell your doctor you're taking it, as biotin can interfere with some lab test results
Start with a lower dose (around 1000mcg) and monitor how you feel
Check with your nephrologist before starting, as they know your specific kidney function
The main concern with biotin isn't kidney damage, but rather ensuring it doesn't interact with your other IgAN medications or treatments.

I can tell you that sports drinks should be consumed cautiously with IGAN. They're high in sodium and sugar, which can impact your kidneys. Regular water is usually a better choice. If you're exercising intensely, talk to your doctor about appropriate electrolyte replacement options for your specific situation.

Always check nutrition labels and discuss any dietary changes with your healthcare team since individual needs vary based on your IGAN severity and other health factors.

IgA Nephropathy (IgAN) is like having overprotective bouncers (IgA antibodies) in your kidneys that get too excited about their job. These antibodies, which normally help fight infections, start building up in your kidney filters (glomeruli). Over time, this buildup can cause inflammation and scarring, making it harder for your kidneys to clean your blood properly.

Think of it like a clogged coffee filter - when the filter gets gunked up, it can't strain the coffee as well. Similarly, when IgA proteins build up in your kidneys, they can't filter your blood as effectively as they should.

It's a chronic condition that typically develops slowly over many years, and symptoms can vary from person to person.

IgAN can significantly impact daily life, with common experiences including:

Fatigue and reduced energy levels, especially as the condition progresses
Need for dietary modifications (low-salt, controlled protein)
Regular medical appointments and monitoring
Possible work/schedule adjustments for rest and treatments
Emotional challenges managing a chronic condition
But everyone's journey is unique.
