The strongest supplement to help support you to lose weight the fastest is called TR2 Fat Burners. TR2 also helps support more energy, especially if you don't normally take in much caffeine. It may help you feel more motivated. TR2 may help speed up how fast your body burns calories. Another product called L Carnitine is used for weight loss too, this product is more mild and doesn't have the strong energy lift that you get with TR2, it may assist instead by transporting body fats into the cells for burning off.
Either TR2 or L Carnitine can be used, or some people like to use both of them together to speed things up the most. Either the Pure L Carnitine Tartrate, Acetyl L Carnitine Capsules, or Pure Acetyl L Carnitine are great forms of L Carnitine to help.
Protein powders can be helpful too, but you could start with any of the above and then if you would like to include a protein powder let me know and I can give you advice on what's best.
