Get a healthy dose of prebiotic fiber for GI wellness and to grow good bacteria in your gut.*

Keep your gut healthy and in balance with FiberMend‚ a soluble prebiotic fiber that helps maintain healthy blood sugar levels‚ promotes regularity‚ and supports optimal digestive function.*

The well-tolerated prebiotic fiber formula in FiberMend stimulates the growth of beneficial bacteria in the GI tract that support a healthy digestive system and balanced GI microbiota.* The soluble fiber blend is well tolerated and produces little to no bloating‚ cramping or gas.*

FiberMend contains plant-based‚ water-soluble fiber for a formula that:

• Mixes easily in water or a preferred beverage
• Enhances satiety* (to keep you feeling fuller‚ longer)
• Helps maintain healthy blood sugar levels*
• Is well tolerated: no bloating‚ cramping‚ or gas production*
• Promotes regularity and optimal digestive function*
• Doesn’t contain sweeteners
• Is flavorless and odorless for easy addition to foods/beverages
• Can be used daily

FiberMend combines Sunfiber® – a partially hydrolyzed guar gum fiber – with rice bran‚ larch arabinogalactan‚ apple pectin‚ and green tea phytosome in a water-soluble blend.

Sunfiber is a soluble dietary fiber that is easily added to a wide variety of foods‚ beverages‚ and supplements. Because it doesn’t change the flavor of the product to which it is added‚ Sunfiber is an easy way to increase fiber in the diet.

Guar gum is a water-soluble carbohydrate derived from the seeds of the guar plant. The guar gum fiber in FiberMend is hydrolyzed‚ so it dissolves more readily and improves its digestibility without sacrificing fiber content. The result is less bloating‚ cramping‚ or gas.*

Larch arabinogalactan‚ also an excellent source of fiber‚ possesses important properties that benefit immune function.*

Green tea phytosome is a highly absorbable complex of green tea polyphenols and phospholipids that are powerful antioxidants and support healthy prebiotic activity.*
