This is a curated list of products we've read about, vetted against peer-reviewed evidence, and would feel comfortable recommending to a friend. Not a shop. Not a deal scraper. Just the small set of things worth knowing about.
Affiliate disclosure: some links below are affiliate links — if you purchase through them, we may earn a small commission at no additional cost to you. The price you pay is the same. We only list products that pass the standards described below.
Small wearable patches that track blood glucose every few minutes for two weeks. Used to belong only to people with diabetes — recent FDA approvals mean over-the-counter versions are now available for anyone curious about their own patterns.
An over-the-counter continuous glucose monitor for general wellness use.
A 15-day wearable sensor on the back of your upper arm that measures glucose every minute and pairs with a phone app. Made by Dexcom, an established medical device manufacturer with decades of CGM experience.
Continuous glucose monitoring research suggests that real-time glucose visibility is associated with improved dietary awareness in non-diabetic adults — though the long-term benefit for people without diabetes is still being studied.
Not a diagnostic tool. Not a substitute for a glucose meter or A1C test. Not a replacement for medical guidance if you have a metabolic condition.

Home blood pressure monitors are one of the few self-tracking tools that have decades of research behind them. Useful for anyone interested in cardiovascular and metabolic health, since blood pressure and blood sugar are tightly linked.
A clinically validated home blood pressure monitor with multi-user memory.
An upper-arm cuff blood pressure monitor with bluetooth syncing to a phone app. Omron is the most clinically validated home BP monitor brand, used in many hospital and research settings.
Home blood pressure monitoring is associated with better cardiovascular outcomes when used consistently — research suggests morning readings tend to be the most predictive of long-term risk.
Not a substitute for clinical evaluation if your numbers are consistently elevated. A single reading doesn't mean much; patterns over weeks do.

Pulse oximeters measure blood oxygen saturation (SpO2) and pulse rate. Useful as a general indicator of cardiopulmonary health, especially during exercise or sleep tracking.
No products listed yet — we're still doing the reading on pulse oximeters. New additions will appear here as we vet them against the standards above.
Every supplement listed here passes the same bar: peer-reviewed evidence indexed on PubMed, a clear mechanism we can explain in plain English, and a manufacturer with verifiable quality standards. If a product can't pass that bar, it's not here — regardless of how high the commission is.
A plant alkaloid with a long research history in metabolic support.
Berberine is an alkaloid extracted from several plants including barberry and goldenseal, traditionally used in Chinese and Ayurvedic medicine. It's now one of the most-studied natural compounds for metabolic health.
A 2022 meta-analysis in Frontiers in Nutrition suggests berberine may support fasting glucose and lipid profiles in adults with metabolic syndrome. Mechanisms appear to involve AMPK activation — the same pathway metformin acts on.
Not a replacement for prescribed diabetes medication. Not safe to combine with metformin without medical guidance — the additive effect can drop blood sugar too low. Always speak to a healthcare professional first.

Books we've actually read and would hand to a friend who asked where to start. No textbooks, no extreme diet manifestos.
Jessie Inchauspé's plain-English introduction to glucose stability.
A practical book by biochemist Jessie Inchauspé covering how blood sugar spikes affect energy, mood, and long-term health. Written for general readers, no scientific background required.
The book draws on existing peer-reviewed research about post-meal glucose responses and the impact of meal sequencing, walking, and food pairing on glucose stability.
Not a medical text. Not the definitive word on metabolism. Some claims are stronger than the evidence supports — read it with curiosity, not as gospel.

Software that genuinely helps with metabolic awareness — without manipulating you into anxiety. Most health apps are noise. These few are signal.
No products listed yet — we're still doing the reading on apps and tools. New additions will appear here as we vet them against the standards above.
Nothing on this page is medical advice. We're educators, not doctors. Always consult a qualified healthcare professional before making changes to your supplements, medication, or routine — especially if you have an existing condition or take prescribed medication.
