More Than a Bathroom Supplement: Inside One Scoop of Fiber+

Most people file fiber under one job. One scoop of Fiber+ carries 10 g of fiber from four sources, prebiotic FOS and two probiotic cultures, and it tastes like something you would actually choose.

By the Project AD Formulation Team Updated October 2026 3 min read
A man in a grey t-shirt pours a scoop of Fiber+ into a blender of mango and banana at his kitchen counter, the Mango Crush Fiber+ tub open beside it and a finished smoothie on the board.

Fiber has an image problem. It gets filed under one job, tolerated rather than enjoyed, and pushed to the back of the cabinet. Fiber+ was built to be the opposite: a daily scoop you actually want to drink.

One level scoop delivers 10 g of fiber from psyllium husk and three more fiber sources, plus prebiotic FOS from chicory and two probiotic cultures. The label's own words: promotes healthy digestion, supports gut flora balance. 35 calories, zero sugar, and 4.9 stars from 37 verified reviews.

No. 1

It is four fibers, not one

Psyllium husk is the name everyone knows, and it is listed first. Behind it sit Fibersol-2, green banana powder and apple pectin. Together that is the 12.9 g Ruminant Fiber Blend: 10 g of fiber per scoop, 8.25 g soluble and 1.75 g insoluble, 36% of the Daily Value.

No. 2

It feeds the gut, not just the schedule

This is the part that makes it more than a bathroom supplement. The 700 mg ProBio-Gest Blend pairs FOS, a prebiotic fiber from chicory, with two probiotic cultures: Lactobacillus acidophilus and Bifidobacterium longum. That is why the label goes past regularity: promotes healthy digestion, supports gut flora balance.

★★★★★

"This is hands down the best tasting and most versatile fiber product out there. I use it in so many ways. I make fiber pancakes with it, fiber truffles, and other things. If I don't have time to make a recipe, I just mix and drink and it is still delicious. Fiber doesn't have to just be for old people!"

"I like the mango, my husband likes the chocolate. Had to get both."

Christine F. · Verified Buyer, May 2026

One scoop a day. That is the whole routine. A daily foundation that tastes good enough to keep, in a tub that lasts a month.
