What is Suppstack?
Suppstack is a free, evidence-based supplement database that helps you build informed supplement stacks using clinical research. You can browse supplements, view evidence summaries, check dosing from peer-reviewed studies, and review safety profiles — all in one place.
How does Suppstack get its data?
Suppstack aggregates findings from randomised controlled trials (RCTs) and peer-reviewed clinical studies published in scientific journals. Each supplement page is built from this research, ensuring the information you see is grounded in actual human trial data.
Is Suppstack free to use?
Yes. Suppstack is completely free with no account or sign-up required. Our mission is to help people make informed decisions about supplements based on clinical evidence, not marketing claims.
How do I build a supplement stack?
To build a supplement stack: first, identify the functional health area you want to improve, and filter the database for supplements with evidence for that area. Then, review the research outcomes for each supplement on Suppstack. Next, check the clinically-matched dosing for the right amount, form, and timing. Finally, review the safety profile for potential side effects and interactions before starting.
What supplements does Suppstack cover?
Suppstack covers a growing database of 100+ evidence-based supplements across categories including vitamins, minerals, amino acids, herbal extracts, and specialty compounds. Popular entries include bacopa monnieri, milk thistle, alpha-GPC, garcinia cambogia, and apigenin.
Are the recommendations backed by science?
Every supplement on Suppstack is backed by published clinical research. Importantly, we show exactly what studies confirm versus what lacks evidence — so you can make decisions based on what’s actually proven, not what’s merely claimed. Where studies conflict or the data is uncertain, our team provides an editorial synthesis that weighs the evidence and offers a balanced interpretation — so you get a clear, honest picture rather than cherry-picked results.
Is supplement stacking safe?
Supplement stacking can be safe when done properly. Key considerations include: understanding each supplement’s effects, checking for known interactions between supplements, starting with lower doses, and consulting a healthcare provider if you take prescription medications.
How is Suppstack different from other supplement sites?
Unlike most supplement websites, Suppstack focuses on clinical evidence rather than marketing claims. We show exactly what each supplement has been tested for, the strength of that evidence, and what results you can realistically expect — no hype, just peer-reviewed research.
Does Suppstack only consider clinical trial data?
Suppstack focuses on clinical trials because they offer the most rigorous standard for measuring whether a supplement works and at what dose. However, we recognise that clinical trials are not the only form of evidence. Many supplements have long histories in traditional, Ayurvedic, and folk medicine, and others show promise through mechanistic or preclinical research that hasn’t yet been tested in human trials — often because of the significant cost barriers involved in running clinical studies on natural compounds that can’t be patented. Absence of trial data doesn’t necessarily mean a supplement is ineffective; it may simply mean it hasn’t been funded for study. Where relevant, Suppstack notes these gaps so you can weigh the full picture.
