Don’t let this fruit mess with your medication.

Grapefruit blocks an enzyme in your gut that breaks down some drugs before they reach your bloodstream. With that enzyme blocked, more of the drug gets absorbed than your dose was meant to deliver, so your body ends up with levels closer to an overdose, even though you only took the normal amount.

This matters most for medications like certain statins (simvastatin and atorvastatin), some blood pressure tablets, and a handful of other prescription drugs.

If you take regular medication and enjoy grapefruit or its juice, check with your pharmacist or GP to see if it’s safe for you. Some drugs are fine, plenty aren’t.

Loads of people have on the same reflux tablets for years and years...

PPIs, like Nexium, omeprazole and lansoprazole, are brilliant for managing acid reflux and protecting against ulcers, but not everyone needs to stay on them for life.

Long term use without review can mask underlying issues.

Stopping them cold after years on them can also trigger rebound acid, where your stomach pumps out even more acid than before and symptoms come back worse for a while.

If you’ve been on the same dose for years with no check-in, it’s worth asking your pharmacist or GP whether you still need it, or whether it’s time to step the dose down instead of stopping outright.

Has anyone tried this stuff yet?? 👀

Trying to lessen the hangover this weekend? What’s in your hangover defense kit?

is a drink you take before a night out, made of 100% Korean pear juice. It’s claimed to help your body process the alcohol better so you get less of a hangover.

UPDATE: I have since tried the PrePear... will do another video on it soon.
