Vitargo is just a carbohydrate powder. The dosage used does not depend on whether you are a male or a female. It depends on your activity levels, goals, rest of your diet etc.
Vitargo is nothing magic. It's just a carb powder. In fact, it'll do more harm then good for most people since drinking your food is a lot less satiating then eating your food.
In my opinion, the only people who really benefit from carb powders are really skinny guys who struggle to eat enough. Everyone else should just eat their carbs - oatmeal, brown rice, sweet potatoes etc.
