Certain ingredients in some of the Herbalife products may cause side effects for certain people. Here are three ingredients that could possibly cause side effects:
1) CAFFEINE:- Some herbalife products contain caffeine as metabolism booster. It can cause nervousness, headaches and higher blood pressure. If you are allergic to caffeine you should avoid the products that include caffeine.
2) PROTEIN / SOY :- Some people are allergic to concentrated protein. Although the body has protein in our cells, the problem occurs when too much protein upsets the balance in the bodyâs ability to process protein.
3) SHELLFISH :- According to Herbalife certain products contain shellfish, so if you are allergic to shellfish then avoid certain products.
Diarrhea and constipation have been reported by some individuals who used Herbalife supplements, especially in the first few weeks of use. In a report published by the "Journal of Hepatology" in 2007, there has been an association between the use of Herbalife products and sudden extremely acute hepatitis.
