Garlic
Also known as: Allium sativum, allicin, garlic extract
Garlic contains sulphur compounds that form allicin when crushed. Garlic supplements may modestly lower blood pressure and cholesterol; the effect on colds is less well supported.
What it is used for
- modest blood pressure reduction – moderate evidence from meta-analyses
- modest reduction of total and LDL cholesterol – moderate evidence, the effect is small
- fewer colds – weak evidence
Forms and how they differ
dried garlic powder standardised to allicin potential
most studied for blood pressure and cholesterol
enteric-coated tablets
protect allicin from stomach acid, less odour
aged garlic extract
odourless, contains S-allylcysteine
tincture
contains alcohol, active content is harder to estimate
Pairs well with
A Mediterranean diet, exercise, less salt; possibly omega-3.
Do not combine / separate
Do not combine with blood thinners or other supplements affecting blood clotting without asking your doctor.
Watch out for
Before planned surgery (usually at least 1–2 weeks ahead), with bleeding disorders, or if you take blood thinners, HIV medicines or other medicines, consult your doctor. During pregnancy use only normal food amounts.
Safety
Do not exceed the label dose; bad breath, heartburn and bloating are common.
Practical tip
With fresh garlic, let it stand for 10 minutes after chopping – more allicin forms.
