Despite its importance, few Americans get the daily recommended intake of fiber through diet alone, contributing to what is called the “fiber gap” that can lead to sub-optimal intestinal and immune health. The good news is that researchers have identified three forms of fiber that together support both immune response and digestion. Life Extension’s Fiber-Immune Support contains a clinically validated dose of beta-glucans — a novel fiber derived specifically from baker’s yeast — as well as an efficacious dose of soluble fiber from the unique fruit of the African Baobab tree and psyllium fiber.
Benefits at a Glance
- Promotes beneficial gut bacteria for digestive health
- Enhances immune system modulation
- Supports immune responsiveness to foreign molecules
- Promotes healthy blood sugar and cholesterol levels already within normal range
Beta-glucans support immune health
Beta-glucans are crucial weapons in the fight for health and longevity. These molecules naturally boost the immune system by increasing its responsiveness to foreign molecules.1 While beta-glucans can be obtained from sources such as shiitake mushrooms and cereal grains, beta-glucans that come from baker’s yeast have a unique molecular structure that grabs the attention of cells in the immune system of the intestine.2-4 In addition, beta-glucans have numerous actions that help supercharge the immune system including promoting the emergence of T-cells5 and interferon-gamma (a powerful immune-modulating signaling protein),6 as well as supporting salivary levels of immunoglobulin A (IgA) which plays a critical role in your immune system’s first line of defense.7
Psyllium fiber enhances digestive health
Fiber-Immune Support also provides psyllium fiber which is obtained from the seed husk of a plantain (unrelated to the edible plantains found in many markets). When compared to the fiber in wheat bran, psyllium leads to greater production of beneficial short-chain fatty acids (specifically butyrate, propionate, and acetate) throughout the colon, perhaps because it is more rapidly fermented by colonic bacteria.8 And when used regularly, psyllium has been shown to beneficially impact cholesterol9 and blood sugar levels10 already within normal range, as well as promoting digestive health.
Baobab fruit powder: unique and novel source of fiber
The powdered, dried fruit of the Baobab tree completes this protective fiber trio. Like psyllium, it has the ability to promote gut health but Baobab fruit pulp may also have unique prebiotic properties. This was demonstrated by a study showing that a 4% solution of the fruit pulp promoted growth of the probiotic Lactobacillus rhamnosus, an organism important in human intestinal health.11 In addition, Baobab fruit is rich in antioxidants for added immune support.
Enhance your immune and digestive health by using this formula’s three sources of fiber together to help close the fiber gap and ensure your whole body health.
