I think my grip strength has improved recently, just as my back pain seems to be diminishing. I started static stretching in the morning, which has helped me with back pain in the past (sciatica).
A couple of years ago I noticed that when I drink home-made kefir my strength overall seems improved. I can't say for sure if my grip strength has improved - it just seems easier to crush empty milk cartons before putting them into the recycle bin.
I discarded my kefir grains before I moved and have only recently found a store-bought brand (Rolling Meadow) I could tolerate. All other dairy causes painful swallowing. Unfortunately it is not always in stock, so I tried making kefir using Yogourmet starter and Rolling Meadow milk, which is grass-fed. It turned out to be better tasting and cheaper, and also I wasn't getting a noticeable effect on strength from the RM kefir - so I'll keep making the Yogourmet plus RM milk kefir.
I wondered if any studies had been done on grip strength and kefir consumption and I found this:

Here's a review on why grip strength is important:
