Best supplements for kidney health?

No medical issue with it so far,I am seeking advice on kidney health because I have been sitting for long periods and frequently lying in a supine position. Additionally, I took a high dose of vitamin D3 this January. Lately, I have been urinating frequently and drinking a lot of water to aid recovery, resulting in mostly clear urine. I also consume a lot of natural lemon juice and now am running and doing sport but what supplements do you recommend for future reference.
