Question about Potassium Nitrate
Hi, I am interested in buying Potassium Nitrate as a dietary supplement. The most popular product is of course Nutriguard's. The problem is, I live in Australia and shipping costs are quite expensive (I haven't received a reply from the company but I estimate that its at least $20). So I am just wondering, can I use Potassium Nitrate that is available in bulk as an explosive and curing meat instead? (Yes I do realize that consuming something that is usually used to make rocket bombs is rather odd and hilarious)
For any Aussies in here, are you aware of a supplier which sells food grade Potassium Nitrate? Most suppliers here sell Potassium Nitrate as fertilizers.....
