Compressed alfalfa tablets may be better than baking soda by: Joe Wheeler
Elsewhere on your site you mention Alfalfa as helpful; I think it may be more helpful than baking soda, since it is one of the most potent blood-alkalinizing agents available.
Easiest way to take it is up to a dozen compressed alfalfa tablets at first twinges of a gout attack; it has worked for me for years. I use Shiff Luzerne alfalfa. Don't chew, just swallow with liquid.
And, you don't get all that extra sodium that is in baking soda (sodium bicarbonate).
