Spirulina & Blood Thinners

Spirulina & Blood ThinnersSpirulina & Blood Thinners

If you are already taking blood thinners, we advise caution if you are considering using Spirulina. At the very least, you should check with your doctor or medical professional first.

More Studies Required

Whilst there are studies (1) & (2) that suggest the use of spirulina does not affect blood clotting time, little is really known about its effects with people who are already taking blood thinners.

There is not enough clear evidence therefore for us to encourage or suggest you might use spirulina if you are already taking blood thinning medication. Our recommendation is that you should err on the side of caution and NOT (repeat Not) use spirulina if you are taking blood thinning medication.

If, however you believe your personal condition or circumstances might allow you to use spirulina, we advise you to check with your Doctor first, before taking it.

History of Spirulina (update)

Can Everybody Take Spirulina?

Most people have no difficulty, but there are a few exceptions.

It’s probably not for those taking blood thinners, unless their doctor has advised otherwise. There are some other serious preexisting medical conditions where it is best to avoid spirulina, we highlight these on our page, “What is Spirulina About?

Those who have a seafood allergy may also wish to double check with their doctor before trying Spirulina.

Most people have no difficulties. However, some do complain about the taste. For that reason, we prefer to take spirulina supplements. Another option is to add powdered spirulina to smoothies or other food.

If you have a serious existing condition we advise you to check with your Doctor before taking it.*
