Does Ultima have carbs?

Excuse me, could you please clarify for me whether Ultima, which I've been hearing so much about lately, contains any carbohydrates? I'm on a strict low-carb diet and need to make sure all the products I consume align with my dietary requirements. Could you also tell me what makes Ultima unique, if it indeed doesn't have carbs, and how it fits into the broader context of healthy eating and nutritional supplements?
