It's very possible that Herbalife is playing a part in increasing creatinine levels (not a good thing!) Herbalife is an MLM - multi-level marketer - that should not be trusted. Its entire business platform depends on people referring others to the company, and it makes its money scamming people into buying their products. Furthermore, most of it's products have serious side effects. Many products contain silicon dioxide and lead, which are toxic for your kidneys, and if consumed regularly, can cause drastic health issues. People have reported getting face paralysis, anemia, kidney dysfunction, skin irritation, sleep issues, irritability, constipation, blood defficiency - a whole host of medical issues! Don't use Herbalife products, as they can cause unpredictable health problems and land you thousands of dollars in debt.
