Side effects of chia seeds

Discover the side effects of chia seeds.

In 99.9% of cases, they are just excellent but misused, they can cause unpleasant effects.

Potential side effects of chia seed


The chia seed is excellent for health and has exceptional nutritional characteristics.

However, in some very rare cases, often when misused, they can cause certain unwanted harmful effects, usually without major consequences, but it is best to know what these harmful effects are and when they can occur.


Before you begin, it’s important to clarify that there is no evidence that chia seeds can produce any unwanted effects or drug interactions with prescribed medications.

This is only a guess and a precaution, not a real contraindication. One study even showed that consuming 50g of chia daily for 12 weeks did not cause any negative effects.

If you stick to the recommended dosages, there will be no problem:


• For adults: 25 to 50 g per day

• For children: 5 to 10 g per day.

That said :

The anticoagulant side effect of chia seeds:

Chia seeds are rich in Omega-3, an essential fatty acid that has mild anti-coagulant properties and which liquefies the blood.

In itself, there is no danger, but an overdose of anticoagulants can cause excessive bleeding or worse, hemorrhages.

People who take anticoagulant treatments such as warfarin, aspirin, or coumadin should take this into account before consuming chia. This is often the case with people who are going to have surgery.

People with hemophilia, that is to say, those suffering from blood clotting problems, are also in this case.

We advise you to consult a doctor advice before doing a chia seed treatment.


The hypotensive side effect of chia seeds

Chia seeds have mild benefits against hypertension, ideal for helping lower diastolic blood pressure (DBP), which is beneficial for most people, which is often why they are eaten.


Indeed, a Canadian study, carried out by St. Michael’s Hospital in Toronto, shows that chia seeds are potentially able to lower diastolic blood pressure.

However, for people with low blood pressure, or under hypotensive treatment, this property should be taken into account so as not to cause harmful effects on health.

Consult the advice of a doctor or pharmacist if you find yourself in this situation.

Chia seed allergy

These are very rare cases, but there are cases of allergies to chia seeds, which are then logically contraindicated. If you are allergic to flax, sesame, or mustard seeds, then you may be allergic to chia seeds.

The reactions to this type of allergies are very varied:

• Most often benign: hives, rashes, redness, and watery eyes.

• But in very rare more serious cases: vomiting, diarrhea, difficult breathing, swelling of the tongue, anaphylactic shock.


If you have any doubts, see a doctor. Usually, people with allergies know this, so don’t overdo it.

Classic gastrointestinal problems:

Indeed, chia seeds are very rich in soluble fiber. According to organizations, eating too much fiber can lead to diarrhea and gas if you eat too much for a short period.

In addition, the seeds are very absorbent, up to 25 times their weight in water. If you consume them in large quantities without drinking enough, they absorb fluids in your stomach and may cause cramps. In this case, they can lead to general dehydration.

There is a case, a 40-year-old American, who developed intense dysphagia, that is to say, swallowing and swallowing problems, following the consumption of chia and after having drunk a glass of water to make descend the seeds into the stomach.

The seeds, on contact with water, formed chia gel which would have caused the symptom.

This is the only case in the world, and it must be said that this man is asthmatic, suffers from numerous allergies, and has already suffered from dysphagia.

If you suffer from a swallowing problem, do not eat dry chia seeds, rehydrate them first.

The high vitamin content of chia seeds

What? They are full of vitamins and is that a problem? Yes, if you take dietary supplements or vitamin supplements it can cause overdose and lead to some harm, depending on the overdosed vitamin.



To conclude this potentially anxiety-provoking article, it should be put in perspective: chia seeds are excellent for your health in the vast majority of cases, people who should not eat them are, or should, already be aware of this restriction.

We hope the article on the side effects of chia seeds has been of help to you.
