Kiera,
Lotioncrafters has by far the best L-ascorbic acid UltraFine. It dissolves instantly. Also the vit E oil they have is nice for using since it also preserves the serum. Covi-Ox T 50 - Lotioncrafter LLC
Skinactives has the SeaKelpBioferment and the ferulic acid. Fast Shopping
You only need the small size of SKB. No need to go overboard until you see if you will like it.
Hope this helps!
