Omega-3—by now, almost everyone knows that it is “somehow important.” Many take it daily. And yet, I keep hearing the exact same sentence:
“I take Omega-3, but it gives me unpleasant burps and I don’t really notice a difference.”
And this is precisely where it pays to take a closer look. Because when it comes to Omega-3, it is not just about taking it – it is primarily about the quality you are getting.
Who is Omega-3 Actually Useful For?
To be completely honest:
For most people.
The reason lies in our modern diet. We have a distinct imbalance between Omega-6 and Omega-3 fatty acids:
- A vast amount of Omega-6 from vegetable oils and processed foods.
- Simultaneously very little Omega-3.
In the long run, this imbalance can impact many processes in the body.
In my experience, the following people benefit the most:
- People under high levels of stress or experiencing exhaustion
- People with inflammatory processes in the body
- People with concentration problems or inner restlessness
- People with a sensitive nervous system
And most importantly:
Our body cannot produce Omega-3 on its own. We are entirely dependent on dietary intake. However, nowadays we rarely eat fatty saltwater fish anymore (which I actually consider very sensible due to heavy metal contamination).
What Happens in the Body Through Omega-3?
Omega-3 is not a classic dietary supplement in the sense of being just “nice to have.” It is a central building block of your cells..
Concretely, this means:
- Omega-3 is incorporated into your cell membranes.
- It influences the flexibility and communication of your cells.
- It plays a vital role in the brain and nervous system.
Furthermore, Omega-3 helps the body maintain a healthy balance of inflammatory processes.
Many people report the following effects when taking the medication regularly:
- Better concentration
- More stable mood
- A calmer nervous system
DHA and EPA – The Crucial Difference
A point that is frequently overlooked: Not all Omega-3 is the same.
The two most important forms are:
- DHA (Docosahexaenoic acid)
- EPA (Eicosapentaenoic acid)
DHA – The Structural Component
DHA is a core component of your brain:
- Important for the structure of your nerve cells
- Crucial for signal transmission
- Relevant for concentration and mental performance
You could say:
DHA forms the foundation of your neuronal structure..
EPA – The Regulatory Component
EPA has a stronger effect on regulatory processes in the body:
- Involved in mechanisms that influence inflammatory responses
- Plays a role in mood and stress processing
EPA is therefore more of the balancing and regulatory component..
Why Both Are Important
Your body needs both.
Many products contain Omega-3, but not necessarily in a sensible composition of these two forms.
Why Plant-Based Omega-3 is Often Not Enough
A common misconception is:
“But I take flaxseed oil, surely that’s enough.”
Plant-based omega-3 (ALA) must first be converted into EPA and DHA in the body.
And this is precisely where the problem lies:
- The conversion is highly inefficient.
- It varies significantly from person to person.
- It is often extremely low.
That means:
Many people consume Omega-3 – but their bodies get enough insufficient EPA and DHA.
The crucial point: quality
Now we come to the part that makes the biggest difference.
Many people take Omega-3 – but in a quality that cannot have the desired effect on the body.
Freshness is crucial
Omega-3 fatty acids are very sensitive.
They react quickly with oxygen.
The fresher the oil, the better.
Poorly stored or older oil may already be oxidized – and that is precisely the problem.
What does oxidation mean?
Oxidation means that the oil reacts with oxygen, producing breakdown products.
You might know this from:
- rancid fat
- old oils that smell unpleasant
And you definitely don’t want these altered fatty acids in your body.
The Totox value – an underestimated quality indicator
The so-called Totox value is a laboratory value that indicates how strongly an oil has already oxidized.
- low value = fresh, high-quality oil
- high value = already damaged oil
A good Omega-3 product should have the lowest possible values here.
Your most important self-test: Taste
A simple but very effective tip:
Trust your sense of taste.
A high-quality Omega-3 oil:
- tastes mild
- is neutral or slightly fresh
- It doesn’t taste strongly fishy.
If an oil has a distinctly fishy or pungent taste, this is often an indication of oxidation.
A very quick processing of the fish is important in the production process in order to keep the oil fresh.
Omega 3: Capsules or liquid oil?
This is one of the most frequently asked questions.
My clear recommendation:
I advise against capsule products.
Why?
Because you have no control.
You can’t:
- smell
- taste good
- assess whether the oil is still good
That means:
You don’t notice when the oil has already gone rancid.
It’s different with a liquid oil:
- You can check it directly.
- you have transparency
- and therefore security
Heavy metals
Heavy metals are unfortunately common in fatty fish. Therefore, Omega 3 oil should be purified of heavy metals and tested for them by an independent laboratory.
Omega-3 for histamine intolerance
One point that is often underestimated:
People with histamine intolerance sometimes react sensitively to omega-3 oils.
Here it can be helpful to pay attention to products that:
- are particularly fresh
- Contains no unnecessary additives
- and are stabilized by antioxidants
One example of this is astaxanthin, which, as a strong antioxidant, can support the stability of the oil.
Quality over quantity
If you take away only one thing from this article, let it be this:
With Omega-3, it’s not the quantity that matters – it’s the quality.
- Freshness is crucial
- Oxidation is a real problem.
- Your body needs intact, undamaged fatty acids.
Therefore, it’s really worth taking a close look here.
