Your retina builds a fatty acid that almost nothing else in your body makes. It packs that fatty acid into the exact place where light gets caught. You will not find it in a meal, because your body was never set up to get it from one. It builds it on site. And it builds less of it as you get older. That last part is why this company exists.
Key takeaways
- Your retina builds its own supply of a rare fatty acid rather than pulling it from food.
- These are VLC-PUFAs, the very long chain fatty acids the retina concentrates in its photoreceptors.
- They are long enough to reach across both halves of a cell membrane, which ordinary fatty acids cannot do.
- Two enzymes build them and only the first one slows with age, which makes it the gatekeeper for the whole line. That same gene is among the most reliable age markers in the human genome.
- In normal systems these are not eaten, they are made. Until recently there was no supply you could buy, and that gap is what vision lipids was built to fill.
Start with what your eye is doing right now
Light enters your eye and reaches a layer of specialized cells at the back of the retina called photoreceptors. Inside each photoreceptor is a tightly packed stack of membranes, folded repeatedly like a deck of cards. This is where light is converted into electrical signals that are sent to your brain and interpreted as vision.
Membranes are built out of fat. Not fat the way we use the word at dinner, but fat as a construction material. That stack has to stay flexible enough to bend and stable enough to hold its shape, all day, for decades. The fatty acids sitting in it are what decide whether it can. So the makeup of those membranes is not a footnote. It is the machinery.
Some fats you eat. Some your body builds.
You’re probably familiar with the common ones. ALA is found in foods like flaxseeds and walnuts, while EPA and DHA come primarily from fish and fish oil. These are the omega-3s you see listed on supplement labels, and they play an important role in overall health.
The ones the retina concentrates are not on that list. They are longer, and your body treats them differently. Instead of absorbing them from a meal, it takes shorter omega-3s and elongates them, adding carbons two at a time, until they reach a length that almost nothing else in the body uses. It runs that assembly line inside the tissue that needs the product, which is a strange and expensive thing for a body to do.
For most of the history of this field, that was the end of the story. There was no supply to buy. Researchers who wanted to test these molecules in animals had to make them chemically, because nothing existed that you could put in a capsule and evaluate. In normal systems, these are not eaten. They are made.
A marine oil manufacturer in Norway now produces a concentrate rich in these very long chains, which means that for the first time they can be put in a bottle and taken by mouth. Your body still builds its own. This is about what happens when that assembly line slows down.
Why the extra length matters
A membrane has two halves, back to back, like two rows of bristles on a brush pressed together. An ordinary fatty acid sits in one row and stays there.
These are long enough to cross over.
That is the part researchers keep coming back to. The leading idea is that by reaching across both halves, these fatty acids help the membrane hold a tight curve, which is exactly what a stack of folded discs has to do. The word the researchers use is believe, not proved, and I will use their word. But the shape of the argument is easy to follow. A rare molecule, built on site, placed in the one structure in your body that has to bend that sharply and keep working.
What changes as you get older
The elongation line has two workers, and only one of them slows down. An enzyme called ELOVL2 does the early steps, taking a fatty acid out to 24 carbons. Then ELOVL4 takes over inside the photoreceptor and runs it the rest of the way, out to 32 and 34. Which makes ELOVL2 the gatekeeper, as ELOVL4 can only work on what ELOVL2 hands it.
In aged mouse retina, ELOVL4 keeps working at the same rate. ELOVL2 does not. The first half of the line slows and the second half is left waiting.
ELOVL2 is also the gene this brand is named after, for a second reason.
ELOVL2 is interesting well beyond the eye. The control region of that gene picks up chemical marks as you get older, and it does it so predictably that scientists use it as one of the most reliable single markers of age in the entire human genome. Not a rough estimate. One of the best clocks biology has.
Those same marks come with less of the enzyme being made, and less enzyme means less handed downstream. In aged mouse retina, researchers stripped those marks off using a drug delivered into the eye, and expression came back up along with age-related visual function. That is a mouse and I will say so. What it tells you is that the pathway does what it looks like it does.
So where does fish oil fit?
Right where it always did. EPA and DHA are well studied, they matter, and nothing here says otherwise.
Fish oil does contain the longer chains too. It contains very little of them, which is the whole reason a concentrate exists. Standard fish oil is built, processed and measured for EPA and DHA, and it does that well, but nobody was optimizing for what sits above them because until recently nobody had a reason to.
Concentration is only half of it. These are long chains carrying a lot of double bonds, which makes them among the most oxidation-prone molecules in any marine oil. How the oil is made and handled directly impacts the product inside the capsule.
None of which is a reason to stop taking fish oil. If you take it, keep taking it. This is the next step up the same pathway.
What we make
Vision lipids is a daily softgel built around this one class of molecule. It supplies the part of the chain ELOVL2 has stopped handing over, so the retina can finish the job itself. The ingredient is named on the label at a disclosed dose rather than hidden in a proprietary blend, so you can look it up and check it against anything written here. The label directs two softgels daily.
That is the product. The evidence around it is what we are building next. Our partners are working on clinical trials, and we are dedicated to building validated science around what is in the bottle.
