  • A pure source of phosphorus for dental health and more

  • The second most prevalent mineral in the body, essential for healthy bones and teeth

  • Pure, food-grade monosodium phosphate powder with no added ingredients

Monosodium Phosphate (MSP) is a source of phosphorous, which is the second most prevalent mineral in the human body next to calcium. Phosphorus is essential for strong bones, healthy teeth and much more. While MSP can be found as an ingredient in some toothpastes, it is becoming popular on its own thanks to the support of some pioneering dental practitioners who believe that low phosphorous intake can negatively impact dental health. Swanson Premium Brand® Monosodium Phosphate provides a pure, food-grade powder.

Rated 5 out of 5 by from Wonderful for mineral soaks I've been adding this to my epsom salt soaks, and it's been helping me feel more in balance and a sense of joy. Hope this stays available in free form and Swanson offers more BOGO's on it!

Rated 5 out of 5 by from CONVENIENT AND COST EFFECTIVE! I have ongoing problems with low phosphorous levels and dietary changes are not helping enough, so I need to take supplements. Phosphorous supplements are not easy to find, especially in the concentrations I need. Your Monosodium Phosphate Granules are convenient and I can easily adjust the amount I need to supplement my diet. They are also very cost effective, 50-75% less than the few other supplements that have been available to me. I also like the easy refill and fast delivery. Thank You Very Much!

Rated 5 out of 5 by from Great product Probably the best source of phosphates I've found. Very pure and the gram scoop is a really nice feature.

Rated 5 out of 5 by from Sweet Xylitol Good stuff; brushing teeth, swishing in mouth for oral health. In a glass of water after breakfast but mainly I do use for oral uses. As everyone cautions, keep away from your dogs -- they are sweet enough (toxic to them).

Rated 5 out of 5 by from Great deal For years my husband and I have been using monosodium phosphate purchased from another vendor at a much, much higher cost...imagine how pleased I was when I discovered Swanson was carrying the same product at a much lower price! Yes, this product does have a strong, salty taste but it works wonderfully. I've noticed that since I'm started taking this supplement in conjunction with calcium that my bone density has improved substantially. Will definitely order from again!

Rated 5 out of 5 by from Works well Figured I'd write this since I gave it a shot, was the best value for phosphorus supplement I found and used it for a month, and is exactly what I expected, some powdered phosphorus to supplement with. And of course don't take it straight or it won't taste good like the other person mentioned, I mix it with a protein shake and don't even taste it.

Rated 3 out of 5 by from bad taste Wanted something for my bones-- I trust the quality, but I can't judge it, it tastes so baaaad. sour bad. It's asmall amount ,and I'm not that fussy, but, can't do it!
