David usually does his own recipes so we do not have the exact measurements. I'd follow him on the video and use the same amount that he demonstrates. For seeds, typically we suggest 1 Tbsp. The superfoods are a bit unique so I'd see what he suggests on the video.
David doesn't say on his video or at least I don't hear it. If you can, please let me know https://www.youtube.com/watch?v=r_Ms36yh_Xo I don't see the recipe on your webpage or his. I don't want to overdo or underdo the amounts.
