I have been using this brand for my tooth powder for about 5 years now. I have had no issues with the order or product. I mix essential oils into my tooth powder and it mixes very well! There is no taste in my opinion after mixing and the powder is of great quality. Get you some!

PROS:* Mixes easily.* Works great as a flocculant. It definitely removes a lot of suspended particles in the water and will help deliver extra clear water for those with such an issue. Removing the suspended particles (proteins/foods) also means that water is cleaner from a nutrient perspective.CONS:* I hate the bag container. Hard to scoop out stuff without making a mess or using a funnel, but not a deal breaker. Good value.USE:I recommend the use of this as a flocculant for saltwater aquariums. It is hard to overdose.Here are excerpt instructions from a thread on water clarity and cyanobacteria treatment in a saltwater aquarium on a popular reefing site (I don't know if I can include links in reviews):"Select a clean container, one that is resealable and able to be shaken. I use an old creatine bottle.(Yes, I am on the GAIN TRAIN)For 500ML of solution, add 10 level tablespoons of powder to roughly 425-450ML of RO/DI water.Shake the bottle up, and let it sit for two hours. After which, it will be ready to use.Now, I don’t believe that you can overdose with this product, but a good recommended dose is 5ml per 50gl of aquarium volume.Be sure to shake up the bottle prior to each use as the powder can settle.The best time to add the solution to you aquarium is after conducting maintenance such as blowing off the rocks, cleaning the glass, siphoning the sand or conducting a water change. Ideally, you should be doing all of the aforementioned maintenance items during a water change, but that discussion is for another time."

Haven’t used it yet, but the powder looks fine. Packaging has a seal which is nice.

I've been using this in the recipe of a tooth powder for brushing our teeth. It's been working really well! Usually, during dental cleanings we are told we have staining that they work to remove, but since I stopped using OTC toothpaste and making our own, our hygienist isn't struggling with staining. Go figure. This product has a super fine powder consistency that works well for my application. Big thumbs up!

Good stuff, bag was already leaking a bit when it got here but was contained in another plastic bag, so messy, but not till you opened it lol. Overall a good buy though

I use this to make my coffee "cowboy style". Use this instead of egg shells to settle grounds and reduce acidity of coffee.

Why why WHY do all TUMS products have a buttload of sugar in them??? I almost always experience my heartburn at night, after I have brushed my teeth. Who the heck wants to have to brush your teeth again just because you had to chew up 4 sugar filled TUMS? It's so stupid! Some TUMS chews might as well be CANDY they're so sweet. Is this the point we've reached as a society? That people hate chalky tastes so much that heartburn chews have to taste like Laffy Taffy???I'm off TUMS for good! No more late night sugar. No more artificial flavors and colors.Now I just take a rounded teaspoon of this calcium powder and stir it into a small glass of water. It dissolves instantly and has almost no taste. It's a bit gritty, but still - NO sugar, NO artificial flavors or colors!Ten minutes later, I burp a few times and my heartburn is taken care of, completely NATURALLY. No worries about tooth decay, no need to brush my teeth again at 2am.

I really can't comment on things like flavor (there isn't any), absorbency (I don't swallow it) or value (I've no point of comparison), but it works great for making my own toothpaste. I mix it with equal parts of baking soda, use organic coconut oil for the base, add xylitol for sweetness and a bit of peppermint oil for flavor. My teeth feel clean brushing with this; I like that I know what I'm brushing them with; and it's WAY cheaper and greener than buying toothpaste.
