Does omega 3 thin blood?

If you’re anything like me, you’re constantly on the lookout for ways to improve your health. From kale smoothies to meditation apps, there’s always something new and trendy that promises to make you a happier, healthier person. Lately, I’ve been hearing a lot about omega-3s – those fatty acids found in fish oil and other sources that are supposed to be good for everything from brain function to heart health.

But wait…does omega 3 thin blood? This is one of the questions I’ve heard floating around lately – so I did some digging (I mean research)to find out the truth. Here’s what I discovered:

What Are Omega-3 Fatty Acids?

Before we dive into whether or not omega 3 thins your blood (spoiler alert: it does), let’s talk about what exactly these mysterious fatty acids are. Omega-3s are types of polyunsaturated fats (ooh fancy terminology), which are considered “good” fats because they can help reduce inflammation in the body and lower cholesterol levels.

There are three main types of omega 3s: ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). ALA can be found in plant-based sources like flaxseed and chia seed, while EPA and DHA come primarily from fish oil.

Omega-3s have been touted for their many potential health benefits (and there’s no shortage of companies willing to take our money). However, did you know that most people don’t get enough omega-3s in their diet (shocking but true!)?

Some Potential Benefits of Omega-3 Fatty Acids

While more research needs to be done before we definitively conclude any benefits with respect trilacyglycerol metabolism, the following have been considered:

  1. Decreased inflammation in the body, which is associated with a variety of health conditions including heart disease and arthritis.
  2. Improved brain function and reduced risk of depression.
  3. Lowered triglyceride levels
  4. Reduction in Blood pressure

Can omega 3 really offer these benefits? It’s possible – but let’s get back to that original question: does it thin your blood?

Does Omega-3 Thin Blood?

Short answer: yes.

Longer answer: There are a couple different ways to approach this question,: Statins medications such as aspirin or clopidogrel can independently fend off clotting, whereas fish oil mainly has an anti-coagulant effect that results from suppressing platelet activation thereby reducing coagulation activity (bah! Terminology Overload) .

EPA/DHA seem to provide fewer procoagulant effects than ALA In terms of deactivates PLT During activation phases however more research needs conducted on this topic before drawing definite conclusions(so we should probably hold onto our money until then).

What Is Anti-Coagulation Exactly?

In order to understand why thinning your blood could be both helpful and harmful, you need to know what anti-coagulants do within our bodies.(I struggle with even saying anti-coa-gu-lant…sounds like some seven syllable monster right out of Harry Potter!)

Simply put,Anti-Coagu-alont?????? seems to make a person bleed longer by delaying normal blood-clot formation, inhibiting formation process of fibrin-thrombin complex,thus augmenting time needed for hemorrhage peaking.

This can be beneficial if you’re at risk for blood clots (like those who experience deep vein thrombosis), as they help prevent clumpses/skeins /masses/clots from forming that can cause many adverse effects. However, risk of excessive bleeding and blood loss is more common with anticoagulation drug usage, particularly in some people or within particular contexts.

So…Should I Be Taking Omega-3 Supplements?

Here’s the deal (bracing myself for potential backlash/remorse ): As much as we are advocating a good intake/want another thing to keep us healthy (or think so anyway), there isn’t really enough definitive research on whether fish oil truly has health benefits. While some studies have shown promising results for conditions like heart disease and depression, additional research is still needed before we conclude anything noteworthy.

That being said, if you’re considering taking any omega 3 supplements (and if you can pour your money down that drain never to return…)you should talk to your doctor first . A medical professional will be able to determine what type and amount of supplement/Diet would be appropriate given your individual needs.


It’s easy to get swept up in trends designed specifically for marketing reasons but at least educating ourselfs gives us an informed basis from whicht o decide where it’s worth investing our time,money and energy. Just remember not everything that glitters(Unicorn waffles anyone?) might actually provide valuable benefits since what works well for someone might not apply precisely into your life situation(if only researchers could always give personalized advice/sigh).

While It’s unknown whether omega 3 fatty acids can thins the blood,in practice differentiating their impact on hemostatic profile profiles remains important such that clinical decisions rely upon realistically incorporating latest industry findings/discussion when assessing benefit-risk tradeoffs by each person who wants incorporate those into their lives.(well done YOU!)
