I have low blood pressure. Are there any supplements I should avoid?
Certain supplements can cause decreases in blood pressure and should be used with caution if you already have low blood pressure. These are melatonin
and large doses of magnesium
. High doses of cannabidiol
(CBD) can cause a modest decrease in blood pressure. Calcium
may also cause a very small decrease in blood pressure. Preliminary studies have found black cohosh
may lower blood pressure in animals, but it is unclear whether it has this effect in people.
There are also a number of supplements that have been shown to lower blood pressure in people with hypertension (high blood pressure). These include fish oil and omega-3 fatty acids
, certain strains of probiotics
, and green coffee bean extract
. While much of the evidence for these is focused on people with high blood pressure, they could potentially lower blood pressure in others. So, if you take one of these supplements and find your low blood pressure becomes even lower, try eliminating the supplement and see if your blood pressure improves.
Note that sexual enhancement supplements with undeclared drugs, such as sildenafil (Viagra) or tadalafil (Cialis) may also lower blood pressure (see the list of Recalls and Warnings
for supplements found to contain these drugs).
