+Testing using US Parmacopeia 24 Dissolution Method 711 determined the absorption availability of the minerals in JF14. Absorption availability refers to the quality of a mineral that is available to be absorbed by the body. The absorption availability of calcium is 23 mg and the total content is 29 mg. The absorption availability of iron is 1.2 mg and the total content is 97 mg. JF14 is not a significant source of iron, and is not sufficient to treat iron deficiency.

  • All-natural mineral powder supports joint health

  • Vegetarian, gluten free
Joint Formula 14 from SierraSil helps promote healthy joint function so you can maintain your active lifestyle. Joint Formula 14 is designed to help make a difference in 14 days or less. The formula uses a pure, all-natural mineral powder with essential minerals including calcium, iron and other trace minerals such as silicon, potassium, magnesium, manganese, copper and zinc. Research shows these nutrients are necessary for proper joint health maintenance. And this is not a one size fits all joint health supplement. The serving size depends on your own personal body weight, providing a more customized joint health supplementation program.

Great product!
A protocall in a bottle, be sure to follow instructions, don't mix with food or it has a decent chance to not go well for you, and a small chance to make you uncomfortable for longer than a few days. I"m not going into details but you just follow instructions which call for you to sit with an empty stomach for an hour before eating anything.

Birds need minerals, too!
For all my fellow exotic bird-lovers, this mineral supplement is a hit! Some of my African Greys, Senegals, and Conures especially seem to crave them. (One of my conures REFUSES to go to bed without her favorite "nut"!) Just give them the capsule, and they'll know what to do with it!
