Tasty Trim Sweetener

Does anyone use this?  My husband brought a few packets back from a gambling junket he took to Coushatta in Louisiana last week.  It is very sweet.  I seem to taste the saccharine in just one packet.  Ingredients:  Dextrose, Calcium Saccharine, Cream of Tartar, Calcium Silicate.  All nutrition info. zeros.  No protein, carbs, fat or calories.  Need an opinion as to whether I should try to find and buy this.  Only 1/2 packet is needed for a mug of coffee so I will use lots less.  Just wondering if it is a known bad product.

It looks like a niche product; I couldn't find much about it through a quick Internet search.  However, I see no reason to avoid it from a bariatric perspective if you like the flavor.

Thanks. So glad you responded. I really value your opinion.  You have a lot of experience and are so logical dead on.  I cannot find it unflavored. I found the hazelnut, chocolate, vanilla etc. but I just want a plain old coffee sweetener.  No flavorings.  I will look again now that I know it is alright to use.
