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 serving 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 2,400 mg. Diets containing no more than 2,400 mg of sodium are recommended for good health.

* 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 supporting healthy tissue and bone health*. Currently, there is no recommended intake 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 serving size 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 support red blood cells and metabolize carbohydrates, fats and proteins*. The recommended Serving for Cobalt alone is 0.004 – 44 mcg/day. The maximum combined serving of Cobalt and Vitamin B12 should not exceed 1000 mcg (1 mg) Vitamin B12 per day (Recommended serving for Vitamin B12 is 6 mcg/day).

SierraSil®’s rich clay mineral structure has strong health promoting properties and supports gentle detoxification*.
