Prebio Complete - 100 g Powder
2 Reviews
From Our Experts
So you want to use prebiotics to best support your gut health. It's a wonderful idea, backed by actual science. Go figure!
Prebiotics, along with fluids and probiotics, help support the gut. They feed the good bacteria that help us digest things, enhance mineral absorption, and help regulate bowel movements.
While a prebiotic isn’t 100% necessary for someone who gets lots of varied dietary fiber with a healthy, normal gut, we feel the benefits of prebiotics are strong.
However, prebiotics with inulin and FOS can lead to bloating, gas, and severe pain!
This is why we recommend arabinogalactan prebiotics - they support proper immune system function and promote the growth of probiotic bacteria such as Lactobacilli and Bifidobacteria in the intestines without discomfort.
This is our top pick!
From The Manufacturer
Arabinogalactans from larch trees are water-soluble polysaccharides that support proper immune system function. They also promote the growth of probiotic bacteria such as Lactobacilli and Bifidobacteria in the intestines, which are important for GI Tract health.

Formulated By This Pharmacist, Not Just Pharmacist
Straight, Simple Answers.
Our customers are some of the most savvy supplement buyers out there. Here are some of their most common, excellent questions we've fielded over the years.
Welcome. For everyone who’s supplement-curious or supplement-overwhelmed, we recommend starting with the First5 — five core nutrients that are commonly missing from even the best diets, and that almost everyone would benefit from. Closing one or all of these gaps has a profound impact on how you feel today and on long-term health. To find your foundation, take the Woodstock Quiz — it identifies which of the First5 you actually need.
Pharmacist-formulated means every product is designed with clinical judgment — not marketing trends. We focus on evidence-based ingredients, well-researched forms, and meaningful doses, while avoiding unnecessary extras. The goal is simple: products that actually support your health and fit into real life.
Yes. All of our products are third-party tested for heavy metals like lead, cadmium, and mercury, as well as contaminants like E. coli, Salmonella, yeast, and mold. Every product we recommend must meet the Supplement Quality Standard — our internal benchmark for quality, manufacturing compliance, sourcing, and value. If a product fails any part of it, we don’t sell it.
No. The First5 are foundational nutrients that many people are missing, but your needs may vary. Some people benefit from all five; others only need one or two. Our goal is to help you focus on what your body actually needs — not take more supplements than necessary.
Most foundational nutrients work gradually. Some people notice changes in energy, sleep, or digestion within a few weeks, but meaningful benefits typically develop over 4–12 weeks of consistent use. Supplements support your body over time — consistency matters more than quick results.
Foundational supplements work best when taken consistently over time, but if a product isn’t the right fit, our team is here to help you adjust your plan. Our goal isn’t to sell more products — it’s to help you build a routine that actually supports your health.
