GBX SeedFiber is unlike any other fiber supplement on the market. It delivers a diverse range of phytonutrients needed for the microbiome system. It’s important to take a daily product that helps the overall diversity of our gut microbiome.

It is specifically designed to optimize the communication between your gut and your brain. It also helps to support microRNA signaling (small, naturally occurring RNAs that regulate gene expression). GBX SeedFiber is actually helping to shift epigenetic patterns that express only healthy genes.

It also helps to manage feelings of tension and stress, brain to brain, gut-brain access, and microRNA signaling tension. It can help bring an unregulated microbiome back into balance (think: after constipation- or diarrhea-inducing medications).

It fortifies raw food creations and has a really high antioxidant level, as well as polyphenols.


GBX SeedFiber contains phytonutrient-rich seeds as sources of natural insoluble fibers. This blend will help you feel fuller, longer. It contains sunflower, cucumber, cranberry, black cumin, blackberry, and concord grape seed fibers. This blend supports the immune system, skin, eyes, brain, heart, and stress response.

Key Ingredients


It contains AHCC, a cultured mushroom mycelia extract. This extract is rich in alpha-glucans and effective for immune support. Alpha-glucans are the number one immune supporting ingredient that help with both innate and adaptive immunity.

AHCC also supports microRNA signaling between the microbiome and the central nervous system. This unique ingredient helps manage feelings of stress, tension, and anxiety. Studies have shown that this active hexo correlated compound can reduce the production of glucocorticoids during times of stress. This means less cortisol.

They also help to regulate dendritic cells, the cells that sense things in the immune system, to regulate the immune response. This is beneficial for gut health, reducing intestinal inflammation, and shifting the microbiome toward more bacteria and less Clostridium.

This product provides a diverse source of fiber that can be added to blended beverages and healthy baked goodies. The tasteless formula means you can add it anywhere that you want to boost fiber and phytonutrient content.

Seed Breakdown

Cold-pressed seeds are an innovative process to obtain high quality seed powder. Most companies use heat to extract all of the fiber, but this exposes the seeds to that heat and alters the thermogenic profiles and alters the profile and the quality of the seed extracts. The heat process provides more of the seed powder per seed, but it’s not as high a quantity. So there’s  more seed powder per seed, but it’s really low quality.

Cold pressed seed powder contains less per seed, but there’s a much higher quality with it.
