Freeda Calcium Phosphate Powder – Kosher Mineral Supplement for Bone & Joint Health in Men, Women, Dogs & Cats – Bone Strength Powder with Calcium and Phosphorus – No Vitamin D – Made in USA, 16oz

This is a valuable dietary supplement that provides both calcium and phosphorus, which are essential for building and maintaining healthy bones and teeth. I am using it for a remineralizing toothpaste I have made. It is unflavored and mixes easily into food or drinks and safe for people and pets. Made in the USA

I fell down on the floor, and my right hip was damaged a bit. After consuming this powder, my right hip healed quickly. I also needed to supplement vitamins and other minerals to actually put calcium and phosphorus in my bones.

What can I say about this powder that hasn't been said for 7000 years. It is special. If the second movement of Mozart's piano concerto #21 has never made sense to you, if you puzzle over some of the aesthetic decisions in Bartok's MIkrocosmos, if you still can't compute the wave function you are in, all will be made cleared by having some of this powder on a Friday night. Or a Tuesday afternoon if you are a shift worker

I find this effective for these two minerals.

Review for 'Freeda Calcium Phosphate Powder - Kosher Calcium Supplement for Men & Women, Animal Bone Health & Joint Support for Dogs & Cats - Calcium and Phosphorus Supplement - Calcium Without Vitamin D, 16oz' in 2023. When you're on keto you lose your electrolytes super fast. In addition, you're restricted diet makes it hard to get all the nutrients you need. Calcium and phosphorous are two of the major electrolytes and this product supplies nearly 100% of both in a single tsp serving. Easy! Also made in USA with our tighter guidelines so I feel comfortable that it's safe to ingest. Note that the powder is SUPER FINE and will absolutely go everywhere if you breathe on it or drop your scoop, but that does make it so it mixes very easily into your food/drink so this is a positive for me.

The label and supplemental facts for the Freeda Pure Calcium Phosphate Powder product have changed and, to me at least, they seem incorrect or, if not, at least inadequate. At the time of my purchase (8/14/2019) the listing of this item only had 1 seller image which was the front view of the bottle and that did not include the supplemental facts. So I had to rely on the customer images that prior customers had posted. I believe the latest customer image (before mine) which showed the supplemental facts was January 29, 2019 which was a lot which expires in June 2021. This shows a serving size of 2.8 grams (which is the same as 2800 mg). This also showed that the calcium phosphate in this case is dibasic calcium phosphate. And it shows that the 2.8 gram serving has 825 mg of calcium and 637 mg of phosphorus. However, it did not specify which form of dibasic calcium phosphate that it is—for example, it could be anhydrous dibasic calcium phosphate, dibasic calcium phosphate dihydrate, or another form. However, we can deduce that it was the anhydrous dibasic calcium phosphate as follows. Anhydrous basic calcium phosphate is CaHPO4 and has a molecular weight of 136.057302 grams/mole. Calcium’s molecular weight is 40.078 so calcium is 0.294567064103623 of anhydrous dibasic calcium phosphate. Phosphorus’s molecular weight is 30.9737620 so phosphorus is 0.2276523313684406 of anhydrous dibasic calcium phosphate. Note that 825/2800 = 0.2946428571428571 and 637/2800 = 0.2275. So essentially such is essentially a perfect match for anhydrous dibasic calcium phosphate and I bought the product thinking mine would be this same product and I was happy knowing what the chemical was that I would be consuming and being confident in the amount of calcium and phosphorus I would be consuming. However, the product I received was different. See my customer images. The container is now different but that is not important (except that it makes it less surprising that there might be some type of change in the product otherwise as well). Note that serving size is now 5.44 grams (5440 mg). It indicates that there is 1414 mg of calcium per serving and 1088 mg of phosphorus per serving. It still indicates that the calcium phosphate in this case is dibasic calcium phosphate but again it does not specify which exact form. Of course one would assume that it is still anhydrous dibasic calcium phosphate since that is what they were using before and that they have merely increased the serving size. The problem is that 1414/5440 = 0.2599264705882353 and 1088/5440 = 0.2. This is no longer a match of anhydrous dibasic calcium phosphate. Perhaps they made a math mistake (or perhaps I made a math mistake—if I am wrong I apologize and someone please comment on my comment and show the explanation and/or alternative math—but even in that case it is still true that Freeda should have indicated which exact form of dibasic calcium phosphate that they are using) or perhaps they are using a different form such as dibasic calcium phosphate dihydrate. Of course, if they specified the form then we would not have to be speculating. The other problem is that dibasic calcium phosphate dihydrate is CaHPO4•2H2O aka CaH5O6P2 (same as the anhydrous except 2 water molecules are added). The molecular weight of dibasic calcium phosphate dihydrate is 172.09. 40.078/172.09 = 0.2328897669823929 and 30.9737620/172.09 = 0.1799858329943634. Therefore the amount of calcium and phosphorus per serving on the new Freeda label would not match dibasic calcium phosphate dihydrate either. In other words I do not have confidence in knowing what I am really consuming in this case. Note that, by contrast, and I am not at all endorsing their product because I have not significantly researched it nor have I tried it, another Amazon listed product, BulkSupplements Dicalcium Phosphate (DCP) Powder, shows in their supplemental information that their product is specifically dicalcium phosphate dihydrate (which is another name for dibasic calcium phosphate dihydrate). Their serving size is 2000 mg and they show that such supplies 466 mg of calcium and 360 mg of phosphorus. Note that 466/2000 = 0.233 and 360/2000 = 0.18. That is essentially an exact match for dibasic calcium phosphate dihydrate. My suggestion for the Freeda product is that Freeda discontinues its current label and instead produces a new label which has supplemental information which indicates the exact form of dibasic calcium phosphate that they are using and then make sure that the supplemental information’s math is correct for the amount of calcium as well as for phosphorus per whatever serving size they elect to list.

Too gritty to use with my toothbrush so not really usable by me but the product seeds good for other uses.

I purchase the Freeda Calcium Phosphate Powder to use as a supplement. I liked that is just calcium phosphate and claims to be free of many other ingredients. As a person with many allergies, I am always hesitant to try something new. The calcium phosphate powder is very fine, the texture feels like cornstarch and this texture makes it easy to incorporate to any food: beans, salads, desserts, rice, anything that I can think of to be able to include it in my diet. I don’t feel any flavor added and I don’t feel any grainy texture. So far is working and I am glad I found it.
