A declining marathon pace became Anna Sandhu’s fastest lesson: when the gut lags, life does too. After a challenging freshman year marked by frequent illness and a noticeable slowdown in her long-distance running, 15-year-old Anna sought answers, finding them in the microbiome. The search didn’t just restore her momentum; it gave her a mission: make everyday gut care simple, inclusive, and science-guided for everyone. That mission became Supplement for Gut Biome (SFGBiome), the company she founded at 17 to bring an all-in-one gut-health supplement, called The Gut Superblend, to the market and to seed a more representative future for microbiome science.
From Setback to Startup
Sport taught Anna how to pace, measure, and iterate. By 13, she had become the youngest female ever to complete the San Francisco Marathon; by high school, she was tracking splits, sleep, and school with equal precision. When recurring fatigue began to derail both classes and training, she started keeping a different kind of log—food, stress, and symptoms—and noticed how often the story traced back to digestion. The pattern pushed her from curiosity to conviction: if the gut is a hub for energy, mood, and recovery, then the solution has to be holistic and sustainable in real life.
At home, she had a front-row seat to the supplement industry. Her parents’ decades-old neutracutical company, Sandhu’s Nutrition, offered separate products you could stack: fiber here, probiotics there. Useful, yes, but complicated for busy people. Anna kept hearing the same friction from friends and teammates: “I’m overwhelmed by bottles and don’t know what to take.” SFGBiome, formulated from ingredients with published evidence and rigorous quality standards, is her answer to that problem.
One Scoop, Not Five Bottles
At the heart of SFGBiome is a first-of-its-kind daily blend, the Gut Superblend, that puts everything your gut ecosystem needs into one scoop: foundational fibers and polyphenols alongside the complete synbiotic stack; prebiotics, probiotics, and postbiotics, plus phytobiotics and plant polyphenols. If that sounds like a mouthful, Anna explains it with a gardener’s clarity. Think of fiber as the soil that holds moisture and feeds good microbes; prebiotics are the seeds; probiotics are the living plants that take root; postbiotics are the beneficial compounds those plants produce; and polyphenols/phytobiotics act like protective nutrients that keep the ecosystem resilient. Most products focus on one or two of those layers. SFGBiome combines them so users don’t have to assemble their own stack or guess at the ratios.
Equally intentional is the powder format. Capsules can cap how much fiber or diverse actives you fit in a single serving; powders make room for comprehensive dosing and easy mixing with water, smoothies, or yoghurt, making it all the more accessible for people with busy lifestyles. The team also prioritized a mild taste and fast dissolve to keep adherence high, and they’re currently launching single-serve stick packs for school, travel, and busy days. The design principle is simple: fewer decisions and more consistency for all.
Built With Guardrails
Anna is the first to say that “science-backed” has to mean more than buzzwords. Before finalizing the blend, for over a year, she consulted with industry experts with decades of expertise in formulation and manufacturing, then set two non-negotiables: quality and practicality. That translates to sourcing from reputable and award-winning suppliers, producing in-house to ensure maximum quality control, and pressure-testing the formula for stability over its shelf life. It also means being careful about language—focusing on structure/function support rather than disease claims, and encouraging customers to speak with their clinician if they have medical conditions, are pregnant, or take medications. SFGBiome is deliberately positioned as a daily support for everyday wellness, not a cure-all.
Designed for Real Life
The best plan is the one you’ll keep. SFGBiome’s routine takes about ten seconds: scoop, stir, sip. New users are encouraged to start gently and build up to a full serving as their gut adjusts. Pair the ritual with a glass of water and anchor it to their biggest meal—breakfast, a post-run lunch or dinner. The company shares simple recipes and practical tips rather than perfectionist rules; the goal is momentum, not micromanagement.
Who is it for? Busy, stressed people who want better days without managing a shelf of pills. Students who need an easy on-ramp to better habits. Athletes who care about recovery, regularity, and routine. Parents juggling school runs and late-night emails. And anyone who suspects that a calmer, more consistent gut could make the rest of life run smoother.
A Bigger Mission: Inclusion in Microbiome Science
SFGBiome is more than a blend; it is grounded in the age-old wisdom of Ayurvedic science, which emphasises the mind, body and gut form one system.
“Everything is connected,” says Anna, the founder, a principle that shaped the product’s whole eco-system design.
That very same systems view guides the company’s science. Since microbiome research has historically leaned on data from a narrow slice of the global population, Anna is building a diverse, privacy-first microbiome dataset so future insights and products don’t just mirror one demographic. Her vision is as practical as it is ambitious: give people a comprehensive, everyday tool today—and invite them (optionally) to help build the evidence base that makes tomorrow’s gut care more personalized, equitable, and effective.
The roadmap doesn’t stop there. Anna discusses developing a curated marketplace of vetted, science-aligned microbiome solutions—think educational materials, accessories, and complementary products that meet the same high standards for quality and clarity. Together, the product, the data initiative, and the marketplace aim at one north star: preventive health that’s simple, inclusive, and grounded in evidence.
What Readers Can Expect
No supplement can replace a balanced diet, sleep, and movement, but the right daily support can make those habits easier to maintain. SFGBiome encourages users to track changes that matter to them: digestion comfort and regularity, perceived energy, focus across school or workdays, and how quickly they bounce back from stress or training. Many people find it helpful to keep a one-minute note in their phone for a few weeks—what time they took the scoop, what they mixed it with, fluids, and any observations. Over time, small adjustments (taking it with breakfast vs. lunch, blending with a fiber-rich smoothie vs. plain water) help dial in what works best for their routine.
How to Join the Community

For Anna, the work began with a setback but grew into a blueprint for inside-out health. “Throughout history, it has, and always will, come back to the gut,” she likes to say. SFGBiome turns that belief into an everyday ritual—one scoop, one small promise to your future self, repeated until it becomes second nature.
