Oxalic acid

Oxalic acid is required in the human body but in a very trace amount. Higher levels of oxalic acid can impact the kidney. When the urine-filtering and urine-formation performance of kidneys are compromised, internal infections are bound to seep into the genito-urinary tract. Such internal inflammations are hard to diagnose but can significantly lower testosterone levels and affect the quality of sperm. Foods like spinach are recommended for your overall health but when consumed continuously over a sustained period, they can lead to an unwanted oxalic acid spike.
