Claiming that you can get a clinical strength formula for fast, clinical strength results, Xenadrine RFA-1 Drink Mix use a fruit punch flavored mix for quick absorption and lasting results. However, you should not exceed 3 packets in 24 hours or within 5 hours of bedtime.

Ingredients: Xenadrine RFA-1 Drink Mix ingredients include garcinia cambogia, raspberry ketones, willow bark, ginger root extract, l-tyrosine, caffeine anhydrous, green tea, theobroma cacao seed extract, wasabia japonica root, capsicum anuum fruit, cytodrine, gymnema sylvestre leaf extract, vitis vinifera seed extract, chamomile seed extract, and guarana seed.

Effectiveness: The only effective ingredients in this blend are based around caffeine, which explains why they advise staying away from it before bedtime. The bad news is that with caffeine, you get results for a short period of time accompanied by several side effects, and then it stops promoting weight loss in general terms. But that would be assuming that they even had significant amounts in the first place, which they do not.

Side effects: Xenadrine RFA-1 Drink Mix side effects include irregular heartbeat, chest pain, dizziness, headache, nausea, insomnia, mood swings, cramping, constipation, diarrhea, tension, anxiety, and high blood pressure if you are sensitive to caffeine.
