NADH Powder Color Consistency

Hi ND Team!
Just some quick questions that I haven't seen already answered: What color is the NADH powder supposed to be? Is there any natural variation in that color between batches? If there is, then given that this is a single-substance powder, what accounts for that variation? Is it oxidation, and if so, does that impact efficacy of the product? Is there any known potential for danger or harm in any variation that could be present in NADH? Are there any concerns about drops in potency over time? (I keep mine in the fridge to have a cool, dry place, as a general best practice.)
I ask because the first time I ordered NADH powder (5g, during the June 2023 summer sale), it was a vibrant, bright yellow, perhaps not that far off of berberine. It stood out starkly when I added it to a stack of white NR, for example. A couple of weeks ago, I started up with the second jar of NADH powder that I've bought (5g again, acquired during the 2023 Black Friday / Cyber Monday sale), and I was surprised to see that it is primarily white-ish, with only a slight yellow tint. If I were presented samples of these two powders without reference to what they are, I would have even guessed that the…

I posted a few photos of the jar I ordered in November 2023, taken within the last twenty minutes, here: https://imgur.com/a/ddzZQVu . Sorry about the quality--I'm clearly not very good at getting the lighting right, but hopefully it's good enough for comparison purposes.
If I had to approximate what the earlier jar looked like from last year's summer sale, it was a little bit less bright than this (https://v4-upload.digoodcms.com/898/image\_1706583646\_S-NAD.jpg), and a little bit brighter than this (https://nmpharmtech.en.made-in-china.com/product/WdptGfXoOuYR/China-Fast-Delivery-Nadh-CAS-No-606-68-8.html). The texture of earlier my ND jar was less "cakey" or "flour-ey" than these two, which I just came across through Google Images, and it had a number of small clumpy shards with a crystalline appearance. Did you guys have multiple sources of the stuff that you stocked for last year's summer sale, or was it all the same? Just wondering if the samples lined up.

It's been the same supplier the whole time. No changes there.
