M&S embraces mushrooms with new ‘YAY! Mushrooms’ range

This really caught my eye in my local M&S - it has taken a while for the power of mushrooms to be fully embraced by most of the UK (I've been writing about mushroom coffee and other supplements that contain mushrooms for a while), but seeing this mushroom range in M&S is surely a sign that these super mushrooms are finally going mainstream.
The range is called 'YAY! Mushrooms' (great name), and focuses on products containing Lion's Mane and Reishi. Most of the products in the range contain Lions Mane, with only a few containing Reishi from what I can see. According to the M&S website, the supermarket worked with scientists at Royal Botanic Gardens, Kew to develop the range, which is interesting.
The products which really caught my eye from this range include these AM shots, which are made with ginger (I love ginger shots already so I'll be giving these a shot for sure):

This vanilla latte in a can, also with Lion's Mane:

And the PM shots made with Reishi. After a quick online search, it seems that some studies have shown that Reishi (Ganoderma) can help with sleep, so it makes sense that the Reishi shots would be intended to consume in the evening.
My only gripe with these products is the lack of information about how much of each mushroom is in them. There's nothing on the M&S website about how much of each mushroom they contain, which is really disappointing. I was recently speaking to my brother about how the new range of TRIP drinks don't contain very much Lion's Mane, only around 100mg per can. Studies showing the benefits of Lion's Mane have had participants consuming as much as 1800mg of Lion's Mane per day, so I hope the M&S drinks don't have these mushrooms in super low doses like the TRIP Drinks.
Anyway, I'll still definitely be giving these a shot.
