Composition
SierraSil Joint Formula14™ is comprised of SierraSil®. SierraSil® is a pure, all natural mineral powder with essential minerals including; silicon, calcium, potassium, magnesium, iron, manganese, copper and zinc. Research shows SierraSil Joint Formula14™ eases joint and muscle aches, reduces stiffness and helps prevent cartilage breakdown associated with exercise and movement*. SierraSil® has strong health promoting and detoxifying properties due to its rich clay mineral structure. SierraSil® attracts and binds positively charged toxins, harmful bacteria and viruses as well as heavy metals, pesticides and other common chemical toxins, facilitating their safe removal from the body. Clinical results available in the Research section.

*SierraSil® is a natural substance that also contains non-significant quantities of other naturally occurring minerals commonly found in nature.
Due to its clay structure, a large percentage of the total content of SierraSil® passes through the body unabsorbed. The values in this table represent the quantities available for absorption by the body in an average recommended daily dosage of SierraSil® (2 g = 3 capsules), as per the dissolution test described in US Pharmacopeia 24 Dissolution Method 711.

Important Notes about this Table
Essential Minerals in SierraSil®: Calcium, Potassium, Sodium, Phosphorus, Magnesium, Iron, Manganese, Copper, Zinc (see back table for specific health functions)
+ The Recommended Daily Intake of Sodium is 1500 mg. Diets containing no more than 1500 mg of sodium are recommended for the maintenance of healthy blood pressure.
* The Aluminum content of SierraSil® is lower than normally present in the environment as well as many commonly consumed foods, including baked goods and tap water. The Upper Limit is 70 mg/day per Joint FAO/WHO Expert Committee on Food Additives (1998). The Upper Limit is the maximum dose likely to be safe in nearly all individuals.
** The Recommended Daily Intake for Iron is 18 mg/day.
++ Silicon is a source of dietary Silica. Silica is required for healthy tissue and bone development and maintenance. Currently, there is no recommended dosage for dietary Silica, but research suggests the body needs from 20 – 200 mg/day.
ˆ Barium is a naturally occurring mineral found in tap water, air, soil and commonly consumed foods such as seaweed, fish and Brazil nuts. There is currently no maximum dosage for Barium in foods or supplements. The maximum allowable level of Barium in drinking water is 2 ppm (2 mg/L).
ˆ ˆ Cobalt is a component of vitamin B12 that helps to form red blood cells and metabolize carbohydrates, fats and proteins. The recommended dosage for Cobalt alone is 0.004 - 44 mcg/day. The maximum combined dosage of Cobalt and Vitamin B12 should not exceed 1000 mcg (1 mg) Vitamin B12 per day (Recommended dosage for Vitamin B12 is 0.14 – 1000 mcg/day).
SierraSil®’s rich clay mineral structure has strong health promoting and detoxifying properties. Due to its charged and porous structure, SierraSil® attracts and binds positively charged toxins, harmful bacteria and viruses as well as heavy metals, pesticides and other common chemical toxins, facilitating their safe removal from the body (Johns & Duquette, 1991)
