For the past two years, I've spent countless hours reading and learning about supplements. I wasn't satisfied with the general knowledge that popular supplement sites offer — surface-level advice driven by affiliate commissions and brand partnerships. But I also wasn't happy with the alternative: the dense, complex act of reading and evaluating scientific studies directly from PubMed.
So I built the best of both worlds: 100% research-backed knowledge that is simplified, made visual and intuitive — giving you the right information from a quick glance, yet allowing you to dive deeper into the research whenever you want.
What started as a personal project grew into something bigger. SupStack now covers 225 supplements backed by over 8,025 studies sourced from PubMed, each one cross-checked against the claims on the site. It's still a work in progress — but every update makes the data more accurate and the coverage more complete.
SupStack is created by Baher Al Hakim — a dentist, technologist, and entrepreneur who has been building in digital health for more than 10 years, with a personal obsession into longevity research and supplements.
While SupStack is a solo project at its core, it has been shaped by a lot of input from friends, colleagues, and domain experts — physicians, researchers, and health professionals who have generously shared their knowledge and feedback along the way.
SupStack operates independently. No corporate sponsors, no investors, no affiliate links. The project is sustained by a genuine belief that everyone deserves access to honest, research-backed supplement information.
Make evidence-based supplement research accessible to everyone — free from commercial bias, marketing hype, and hidden agendas.

Every supplement gets an evidence score from 0 to 10, based on the quality and quantity of peer-reviewed research. Here's what each tier means:
8–10
Very Strong
Multiple meta-analyses and systematic reviews. Strong scientific consensus.
6–8
Strong
Several RCTs with consistent results. Good evidence base.
4–6
Moderate
Some RCTs but results may be mixed or sample sizes small.
0–4
Emerging
Preliminary data, mostly preclinical or observational studies.
For the full methodology including how scores are calculated, weighted, and validated, see the methodology page.
Each supplement gets a score based on how strong the research is. Not opinions — actual studies you can check yourself.
Pick what you're trying to improve, and SupStack shows you what's most likely to help based on the evidence.
Can't decide between two supplements? Compare them on dosage, timing, effects, and safety all in one place.
Drug interactions, side effects, and who should avoid what. The stuff that's often buried in fine print elsewhere.
Save the supplements you're taking or considering. Get a shareable link to show friends, trainers, or doctors.
Run N-of-1 experiments on yourself. Set a baseline, follow a protocol, do regular check-ins, and get a personal verdict on whether a supplement works for you.
Every supplement on SupStack goes through an automated validation pipeline that checks claims against real research. Here's what that looks like in practice:
The validation pipeline catches inconsistencies automatically — like a safety rating that's too generous given what the studies actually found, or an evidence score that doesn't match the ratio of positive to negative findings. When issues are found, the content gets updated. Read more about how this works on the methodology page.
No products, no affiliate links, no sponsored content. Just information.
Every rating links back to the research. Don't take SupStack's word for it — look at the studies yourself.
If the evidence is weak or mixed, SupStack says so. No point pretending something works when the research isn't there.
Every supplement is cross-checked against its studies automatically. Safety ratings, evidence scores, and dosage claims all get audited — and corrected when the data says otherwise.
SupStack is for informational purposes only — it's not medical advice. Always talk to a doctor before starting any supplement, especially if you have health conditions or take medications. What works in studies doesn't always work for everyone, and supplements aren't meant to replace proper medical care.
