Evidence-led analysis
Honest, cited reads on the supplements people actually take. We sell no supplements, so nothing here is a sales pitch: just the evidence, and what it does and does not support.
Supplements are not tested before sale the way medicines are. What third-party certification actually covers, and what no interactions check can see.
Berberine has a real, drug-like effect on blood sugar, and that is why it interacts. The honest map of what to monitor and what to avoid.
Two things people believe about Lipitor and supplements are backwards. The CoQ10 everyone takes may not help, and red yeast rice is a statin in disguise.
Everyone knows to space calcium and iron away from Synthroid. Two other supplement interactions get missed: one moves your level, one fakes your blood test.
Ozempic barely interacts with supplements: it is not cleared by the liver enzymes that cause interactions. The real issue is what eating far less leaves out.
The warfarin advice everyone repeats, avoid leafy greens, is half wrong. The real rule is consistency, and the risky interactions are elsewhere.
The natural mood supplements sold side by side, St John's Wort, 5-HTP, SAMe, are the exact ones to check against Zoloft. Two are a hard stop. Here is why.
Autophagy is real, and the switch responds to fasting, exercise and weight, not to a capsule. What the spermidine and urolithin A evidence shows.
A 2026 genetics study in Gut linked vitamin B1 metabolism to IBS. It is a GWAS and a dietary association, not a trial showing that B1 treats IBS.
PEA is one of the few IBS supplements with real randomised trials. What they show, what they do not, and why it sits at Grade B: promising, not proven.
Ozempic, Wegovy and Mounjaro take the weight off, but some of it is muscle. The 40% headline is overstated, and protein plus resistance training are the levers.
At least 19 of England's 25 most-prescribed medicines have a common supplement that interacts with them, lined up against real NHS prescribing volumes.
Google had indexed 22 of our pages. Eight days later it was 354. Four separate pieces of work, done weeks apart, that only paid off when the last one landed.
A UK regulator told ZOE its Daily30+ ad could not say it was just real food. Both sides were right, and both missed the structural point.
Why the back of a supplement bottle tells you more than the front. Magnesium, folate, omega-3 and vitamin D: the form on the label is the dose your body sees.
How Distil grades every compound on published evidence, why the grade has to be per-form and not per-name, and why the rejection list is the real product.
A supplement report business that does not sell supplements. The reasoning behind Distil’s anti-funnel design, and the rules behind the personalisation.
