No, they are not the same thing. Omega-3 supplements provide EPA and DHA, the fatty acids your body uses to produce Specialized Pro-Resolving Mediators (SPM). However, converting omega-3 into these specialised molecules is a complex, tightly regulated biological process, so increasing your omega-3 intake does not necessarily translate into greater SPM production. Lipinova® supplies SPM directly, providing the bioactive molecules involved in the natural process of inflammation resolution.

If you have ever looked into how to care for your joints, you will have come across both of these terms. They sound similar, they appear on the same labels and plenty of people use them interchangeably. They are not the same, and understanding why can save you months of trying products that do not do what you expected.

One note before we start: SPM here stands for Specialized Pro-resolving Mediators. In Spanish the acronym happens to be shared with premenstrual syndrome; the two have nothing to do with each other.

The difference, in one sentence

Omega-3 is like the ingredients of a recipe. SPM are the finished dish. Having the ingredients in the cupboard matters, but it does not mean the dish is going to cook itself.

Your body has to transform omega-3 into SPM through a complex, tightly regulated biological process. That is why consuming more omega-3 does not guarantee greater SPM production. Lipinova® SPM supplies SPM directly, giving the body the bioactive molecules involved in the natural resolution of inflammation without depending on that conversion step.

What omega-3 is and what it does in your body

Omega-3s are a type of essential fat. “Essential” literally means your body cannot make them and has to get them from outside — from oily fish, certain algae or a supplement.

EPA and DHA: the two fatty acids that matter here

Within the omega-3 family the two main players are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), found above all in oily fish. They are what your body uses to make SPM.

There is a third one, ALA, which is plant-based and found in flaxseed, chia and walnuts. Your body can convert it into EPA and DHA, but it does so with very low efficiency. That is why, when omega-3 and inflammatory processes come up, the conversation almost always revolves around EPA and DHA.

Why taking more omega-3 does not mean producing more SPM

A conventional fish oil provides EPA and DHA in unconverted form. It is a good source of omega-3 with recognised benefits, particularly for the maintenance of heart and brain function. But for those fatty acids to take part in the resolution of inflammation, the body has to convert them into SPM, and that conversion is a complex, tightly regulated process.

And it is not always efficient. Ageing, stress, an unbalanced diet, lifestyle or a sustained inflammatory background can all reduce the body’s capacity to produce SPM. So even with a high omega-3 intake, production of these molecules can fall short (Calder, 2020; Chiang et al., 2020).

Lipinova® SPM works differently: it supplies SPM directly, in the required dose, without depending on the body having to produce them from omega-3.

What SPM are and why everyone is talking about them

SPM (Specialized Pro-resolving Mediators) are molecules your body produces. They were first described just over two decades ago at Harvard University, in the work of Professor Charles N. Serhan, and they overturned an idea everyone had taken for granted: that inflammation simply faded away on its own, by exhaustion.

It turns out it does not. Inflammation is not switched off, it is resolved — and that resolution is an active process with its own signals and its own messengers. SPM are those messengers.

Resolvins, protectins, maresins and lipoxins

Under the “SPM” umbrella there are four large families of molecules, each with its own role:

  • Resolvins: involved in the “mission accomplished” signal that slows the arrival of further inflammatory cells.
  • Protectins: studied above all in nerve tissue and in cell-protection processes.
  • Maresins: take part in the clean-up phase and in tissue regeneration.
  • Lipoxins: the first to be described, they act as a braking signal on the inflammatory process itself.

What “resolving” an inflammatory process actually means

It is worth pausing on this word, because it explains everything. A classic anti-inflammatory works like a switch: it turns the signal down. Resolution is something else. It is the clean-up crew that comes in when the building work is finished, clears away the rubble and leaves the site ready to be used again. Interrupting something is not the same as resolving it, and SPM take the second route.

What slows the conversion of omega-3 into SPM

This is the crux of the whole matter. The pathway that converts EPA and DHA into SPM does not work the same in everyone, or at every stage of life.

The factors research has identified

  • Age, which reduces the activity of the enzymes involved.
  • Accumulated physical wear and repeated loads of effort.
  • Sustained stress and lack of rest.
  • A diet high in omega-6 and low in omega-3, which competes for the same enzymes.
  • Situations where the inflammatory process drags on and exhausts the capacity to respond.

In other words: the amount of omega-3 you take is only part of the equation, and not the part that decides the outcome (Calder, 2020; Chiang et al., 2020).

Why some people take omega-3 and notice no change

It is a story that repeats itself. Someone takes omega-3 capsules for months, sticks to the dose and notices very little in their joints. The usual conclusion is “omega-3 does nothing for me”.

The explanation may be a different one. The supply was there; what never completed was the conversion. You had the ingredients, but the recipe was left half-made.

What all this has to do with your joints

Joint discomfort that lingers over time tends to go hand in hand with inflammatory processes that never quite resolve. It is not just that “there is inflammation”: it is that the final phase, the one that should clean up the area and leave it ready to repair, stalls halfway.

It happens to people carrying years of wear and tear, and also to people who put their joints through demanding training loads. Seen that way, if what you want is to support that final stretch directly, it makes sense to supply ready-formed SPM rather than relying solely on your body to manufacture them.

It is the difference between having a full cupboard and having the dish made.

Lipinova® SPM: the ingredient that supplies SPM directly

Lipinova® SPM is a patented marine-derived SPM ingredient, developed by Solutex GC in collaboration with Dr Charles N. Serhan, who discovered the Specialized Pro-Resolving Mediators. Behind it lie more than twenty years of research into bioactive lipids.

Unlike conventional omega-3 ingredients, Lipinova® SPM supplies SPM and their direct precursors, without the body having to handle the conversion.

What the published research has observed

Lipinova® SPM does not stop at theory. It is the only SPM ingredient with pre-clinical and human clinical studies published in peer-reviewed scientific journals, in which an increase in blood SPM concentration has been observed after its consumption, together with shifts in the immune response profile towards resolution.

One thing is worth pointing out. SPM are not equivalent to conventional omega-3 supplements: although they derive from EPA and DHA, they act as bioactive mediators with a distinct role, so the clinical evidence for the two types of intervention is not directly comparable. That very difference is what places Lipinova® SPM in a category of its own.

How to find your bearings

There is no single answer, but there are signals that help.

  • If you have been taking omega-3 for a while and are not noticing the effect you expected in your joints, it is worth asking whether the bottleneck is in the conversion.
  • If you are at a stage or in a situation where that capacity may be reduced (age, sustained stress, demanding training loads), the direct supply of SPM makes more sense.
  • If you want to act on the resolution phase without depending on a metabolic process you do not control, ready-formed SPM are the shortest route.

And if you have any doubt about what suits you, especially if you take medication regularly, talk it over with your doctor or pharmacist. It is the best way to get it right.

What to remember

  • Omega-3 (EPA and DHA): the precursor. Necessary, but on its own it does not guarantee that SPM will be produced.
  • SPM: the molecules that give the resolution signal of the inflammatory process.
  • The conversion from one to the other is complex and loses efficiency with age, wear and stress. Taking more omega-3 does not compensate for it.
  • Lipinova® SPM: supplies ready-formed SPM, in the required dose, without depending on that conversion.

Frequently asked questions

Are SPM the same as omega-3?

No. Omega-3 (EPA and DHA) is an essential fatty acid you get from your diet or a supplement. SPM are molecules your body makes naturally from those fatty acids, through a conversion process that is not always efficient.

What exactly does SPM stand for?

SPM stands for Specialized Pro-resolving Mediators. They were first described at Harvard University in the early 2000s. In Spanish the acronym happens to coincide with premenstrual syndrome; the two are unrelated.

Will taking more omega-3 make me produce more SPM?

Not necessarily. Converting EPA and DHA into SPM is a complex, tightly regulated biological process influenced by age, stress, diet and lifestyle. Raising your omega-3 dose does not guarantee more SPM will be produced.

Can I get SPM from diet alone?

Your body makes them from the EPA and DHA in oily fish, so a fish-rich diet provides the starting fatty acids. What diet cannot guarantee is that the conversion happens efficiently.

Can omega-3 and SPM be taken together?

Yes — they are not incompatible, because they cover different functions. If you already take an omega-3 for cardiovascular or general reasons, you can keep it up. For any doubt about combinations or doses, check with your doctor or pharmacist.

How long until the effects are noticeable?

It depends a great deal on each person and their starting point. As a general rule, food supplements need consistent intake over several weeks before it makes sense to judge the result. Regularity matters more than any single dose.

Do SPM have side effects?

SPM are molecules your own body produces naturally. In the published clinical studies with Lipinova® SPM no relevant adverse effects were recorded. Even so, if you take anticoagulants or any medication regularly, check with a healthcare professional first.

What exactly is Lipinova®?

Lipinova® is a patented marine-derived SPM ingredient, developed by Solutex GC in collaboration with Dr Charles N. Serhan, who discovered the Specialized Pro-Resolving Mediators (SPM). Unlike conventional omega-3 ingredients, Lipinova® supplies SPM and their direct precursors. It is also the only SPM ingredient with human clinical studies published in peer-reviewed scientific journals.

Is collagen or SPM better for joints?

They act on different things. Collagen is a structural component of the tissue, while SPM are involved in the signalling of the inflammatory process.

Is a supplement with Lipinova® SPM a medicine?

No. Supplements formulated with Lipinova® SPM are food supplements. They are not a substitute for a varied, balanced diet or a healthy lifestyle, and they are not intended to prevent, treat or cure any disease.
