Borrowed Light

A June Strawberry Moon Reflection

Aloha Seatopians,

On the 29th of June 2026, the Strawberry Moon will rise full over the water, and like every full moon, it will look like it's shining.

It isn't.

The moon makes no light of its own. The light reaching your eyes began at the sun, traveled roughly ninety-three million miles, struck a silent grey rock, and returned to us as reflection. What we call moonlight is borrowed light — sunlight, handed down one more time before it reaches us.

I've been thinking about that, because the ocean does the same thing. Only slower, and with more care.

Sunlight falls on the surface of the sea, and the smallest things alive — microalgae, drifting in the upper few meters — catch it. They were among the first life on Earth to learn the trick, billions of years ago: take light, and fold it into something living. One of the things they fold it into is a molecule called DHA, a long-chain omega-3 fat. A small fish eats the algae. A larger fish eats the small one. And somewhere down that line, the light the algae caught becomes the structure of a retina, a nerve, the architecture of a brain.

Your eyes are, in a real and literal sense, built from borrowed light. So is a good part of the wiring behind them.

I think this is the quiet thing the moon has to teach us this month. Light alone doesn't nourish anything. It has to be caught, carried, transformed, and handed down into a form a body can actually use. A label can promise milligrams of omega-3, but your bloodstream asks a more specific question: did the EPA and DHA arrive in a form your body recognizes? 

The science here is more precise than "fish is healthy," and I find the precision beautiful. Plant sources — flax, chia, walnuts — are real foods, but they hand your body a precursor, a starting material it has to convert into DHA, and it does that conversion poorly. The marine food web does that work before it reaches your plate — microalgae make the DHA, fish concentrate it, and it arrives preformed, in natural lipid forms your gut is built to digest and absorb. The difference isn't fish versus plants. It's finished versus unfinished. Light that arrived ready to use, versus light still asking to be assembled.

And whole seafood carries more than the omega-3s. It arrives as a whole meal — complete protein, selenium, B12, vitamin D — a package no capsule reproduces. There's one more thing it has that a supplement doesn't: you actually look forward to it. A pill you forget on the counter delivers nothing. A dinner you can't wait for delivers every time. It's okay for your supplement stack to be your favorite meal.

Here's what borrowed light looks like on a plate.

One 6 oz portion of our Bakkafrost Atlantic Salmon delivers 1,964 mg of EPA + DHA — verified by third-party wet-chemistry lab testing across six production samples, not estimated, not a database average. That's the better part of the ~2,000 mg of daily intake that peer-reviewed research models for reaching an Omega-3 Index of 8% or higher — in one dinner, in the natural form, already made. (That figure is the modeled intake to move a deficient person toward the 8% target; maintenance is likely lower, and individual response varies.)

And because we'd rather you measure than take our word for it: the honest way to know any omega-3 routine is working is to test your Omega-3 Index before, and again after. Not just a meal. A metric. The whole point of verified marine nutrition is that you never have to take the light on faith — you can watch it become part of you.

The moon will be full on the 29th June, reflecting a sun it will never touch. The sea has been doing the same thing far longer, and far more generously — catching the light, and handing it to us in a form we can live on.

Our job is to choose food that honors that lineage. And then, if we're being rigorous about it, to measure what it does.

Know your number. Feed it well.

With gratitude,
