Great product.

Powder form. There's no strong scent for this fiber mixture. Very suitable for soft drinks. I usually add one scoop inside my tea in the morning. The quality was fine and the powder was so tiny that I couldn't even feel the taste of the fiber. Pretty great for fiber supplement.

Great gut formulation

A spectrum of fiber that is great for restoring gut microbiome. Not cheap but unique formulation. I like that it is unflavored, taste is neutral.

Gentle, Effective Multi-Fiber for Digestive Health

I’ve been using Vitauthority Fiber Fix Multi-Fiber Gut Aid (unflavored, 8.46 oz/240 g) daily and I’m really happy with it. The quality feels excellent with a blend of soluble fibers that mix smoothly into water or smoothies without clumping or taste. I take one scoop with breakfast each day and have noticed smoother digestion, more regular bowel movements, and less bloating. The resealable packaging keeps the powder fresh, and it fits easily into my daily wellness routine.
