I'm so glad you find it helpful! I buy Eden or Kevala brands, Eden preferred as it has slightly more calcium then Kevala (2 Tblsp at 35% as compared to 31%). I think they are unsalted. They do have a very strong flavor but as I said, I take it like a spoon full of medicine so it doesn't bother me. If you need to sweeten it, you can use the blackstrap molasses which also adds some calcium. But that's another strong flavor not to everyone's liking. You can also drizzle it over some non-dairy yogurt and berries to mask the taste if you need to. I stock up on the molasses and tahini from Vitacost when they have their 15% off sales.
Some other non-dairy calcium sources I use a lot are almonds, white beans, chia seeds (I make crackers), figs (spread with black tahini 🙂 ), oranges, carrots, other dark greens like broccoli, kale and bok choy though collards pack the most punch so I make sure to have those at the start of every day.
