'Cats serving on RMN vessels before the war probably weren't away for long enough for deficiencies to be serious.
But once the 'cats started emigrating to other worlds, and especially raising kittens there (who, as they're still growing and developing the capabilities, probably need the compound more acutely than adults do) it would be critical to ensure they have access to that compound.
I don't know if the Manties could have gene-engineered some plant to create it directly, or if they'd have simply gone for working out industrial manufacturing of it by pharmaceutical companies (making it into, say, a supplement pill) -- but either way the information that a specific compound was needed for the long term health of 'cats would become far more widespread. And spreading its production and/or availability to more worlds would make it easier to acquire samples, or even the existing production instructions.
But given how Honor was discussing it, I don't think it's been treated as a state secret. The level of intelligence and the fact that they are truly telepathic, yes. But that they were good at empathy wasn't and that this particular nutrient was important in their diet.
It would be obvious to any biologist or geneticist that a species need certain nutrients found usually on the planet where they've evolved. No Alignment lab would make the mistake of lacking of Sphinxian native food, including that of other species that treecats would usually prey upon, like chipmunks. Honor's house on Grayson had some for the treecats there.
I aldo don't think the treecats aboard RMN ships lacked for the nutrients they needed. For one thing, the RMN would have proper food for them: the institutional knowledge was there. Honor as a cadet on her snotty cruise was able to feed Nimitz properly and her captain (Bachman) invited Nimitz to join them the Captain's table whenever he invited her. Moreover, I think it's not even difficult for the RMN, because their food is obtained from the same source: the MBS. Celery was an import and so must have a lot of others, but the Manticore population probably eats locally-evolved food too (with human-required nutrients fixed in).
I'd think it could be difficult to identify every significant trace nutrient or vitamin that the animal needed from their environment - especially ones that take a long time for symptoms to appear. (Just an example, deprive a human of vitamin C and it'll take about 3 months before symptoms of scurvy appear)
That was so tricky that the Royal Navy ended up making changes to their antiscorbutics in the 1800s that rendered them utterly ineffective[1], and it took decades for them to notice. (Basically until their Arctic and Antarctic expedition's started coming down with scurvy) Because, coincidentally, the changes that ruined their effectiveness coincided with improvements to ship design and propulsion that meant it was no longer common for ships to be a sea for months between port calls. So while their onboard diet was nearly free of vitamin C their ships almost always reached port (and fresh foods containing vitamin c) before scurvy could become apparent.
So I wouldn't be surprised if it took quite a while to work out that purple thorn (or Sphinxian celery) was critical for the 'cats -- much less to isolate the specific compound within it that was; so you could ensure that food or supplements with the necessary levels of that compound were provided.
And it's unlikely that you'd be able to recreate their entire habitat and ecosystem just to ensure you didn't accidently miss a critical trace compound in their diet.

[1] The RN did at least a couple things that ruined their previously effective lime juice based antiscorbutic (though not all of them at the same time, or on all ships). They started storing the juice in large copper containers, which reacted with the acidic juice to break down the vitamin c. And they started canning and boiling the juice, to preserve it for long endurance missions, and it turns out boiling destroys much of the vitamin c.
Of course all of this was before vitamin c was isolated and identified; much less when it was identified as the thing that prevented scurvy -- so that makes it harder to test to see if the changes ruined the effectiveness. They'd have had to do a series of 3+ month long comparison tests, with participants cut off from fresh food, to determine whether a given preparation or storage method harmed the antiscorbutic property.[/quote]
Actually it was the Spanish who first noticed scurvy. With their long voyages in the early to mid 16th century. Captain Cook was one of the first to understand and combat scurvy by using sauerkraut. When he first tried using it his crew would not eat it. So he used subterfuge. He had the barrels of sauerkraut stamped OFFICERS SUPPLIES and let pilferage take care of things.
