Hi Merhabi Thx or Using Health Care Magic Regarding Via Ananas, there r 2 types in the market the genuine one & the fake The Fake is not helping by any ways as it is just having a placebo effect About the Genuine Via Ananas : FDA believed that it contains an element of Sibutramine which was withdrawn from the US & Canada markets (was in the form of drug named Meridia) Drugs containing Sibutramine helps in losing weight but have many side effects, including: 1. Dry mouth 2. Nausea, strange taste in the mouth, upset stomach and constipation 3. Trouble sleeping, dizziness, drowsiness, headache and flushing 4. Menstrual cramps/pain 5. Joint/muscle pain 6. fast/pounding/irregular heartbeat, numbness/tingling of the hands or feet, may predispose heart attack or stroke 7. Mental/mood changes (e.g., excitement, restlessness, confusion, depression, rare thoughts of suicide) 8. Change in the amount or color of urine, easy or unusual bruising/bleeding, black stools, vomit that looks like coffee grounds, yellowing eyes or skin, unexplained fever, shaking, unusual sweating and swelling of the arms/legs 9. Rarely may cause; seizures, chest pain, weakness on one side of the body, vision changes, trouble breathing Finally , I am not recommending using Via Ananas at all Thx in advance Dr. Peter S Clinical Nutritionist
