How long does it take garlic capsules to help lower blood pressure - I am already on two types of b.p. medication and while it is much better the bottom number is still around 90 - Id like to lower it more and was hoping taking garlic capsules would help...???
Garlic capsule and cod fish oil are advocated for lowering of BP.  However, large trials have not been able to prove direct association.  Also, the individual papers achieved max 4-5 mm fall in Upper systolic and 2-3 mm fall in lower diastolic.  So if you want to take garlic capsule for over all health benefit, it's ok.  But please don't substitute it as one antihypertensive.  Also, as I said the max achieved should be borne in mind.  Regards Chat Doctor.
