Although it is sold primarily as a protein powder, the formula is not only protein. Alongside the plant protein and added vegan-source BCAAs, it contains inulin from chicory root, vitamin B6 and maca.
Inulin is a prebiotic fibre, meaning it feeds beneficial bacteria in the gut. That can be a positive feature for digestive variety, but it also has practical implications. Fibre takes some getting used to, especially if your usual diet is low in it. Some people may notice bloating or gas when they first increase their fibre intake. This is common with many types of fibre, not something unique to this product, but it is a good reason to start with a smaller serving and increase only once your stomach is comfortable.
Vitamin B6 contributes to normal protein and glycogen metabolism, so it supports the way the body uses nutrients. Maca is a traditional Peruvian root commonly chosen in active lifestyle products. In this formula it adds another plant ingredient, but the product information notes that most people choose this powder first and foremost for its protein content and digestibility, not for maca alone.
If you have a sensitive stomach, the safest approach is to try a small amount first, mixed with plenty of liquid, and observe how you feel. As with all supplements, this is not a substitute for balanced food choices, and it is not intended to diagnose, treat or prevent any condition. If you are pregnant, breastfeeding or on a specific eating plan, check with a specialist before using a product with added active ingredients.
