Many supplements claim they can relieve aches and pains, improve overall joint health, build cartilage, and more. SierraSil is one such supplement. When looking for a supplement, you should try and read the labels. First, you must understand the ingredients present in the supplement, how you should take it, and what you should expect after taking it for a defined period of time.

Many brand name joint supplements contain glucosamine, chondroitin, MSM, or SAM-e or combinations of those active ingredients. SierraSil is an all-natural mineral complex that does not contain any of these four ingredients.

What Is SierraSil?

SierraSil is available as SierraSil Joint Formula14, which comes in a bottle containing 90 capsules and claims it can promote joint health and mobility. The manufacturer claims that it provides joint pain relief and that SierraSil has a clay mineral structure, which, aside from promoting better joint health, has detoxifying properties.

Ingredients

According to the website, SierraSil is a "pure, all natural" mineral powder. SierraSil contains the following mineral amounts in three capsules:

Calcium 23 mg
Potassium 20 mg
Sodium 12 mg
Aluminum 6 mg
Phosphorus 3.1 mg
Magnesium 2.2 mg
Iron 1.2 mg
Silicon 1.0 mg
Manganese 0.15 mg

Recommended Dosage

The manufacturer recommends taking SierraSil Joint Formula14 capsules with water only. They suggest taking all capsules for the day together. Food or other beverages (coffee, tea, milk, or juice) should be taken 30 minutes after or two hours before SierraSil Joint Formula14. Other medications or supplements should be taken at least four hours before or after the supplement. It is also recommended that you drink at least eight glasses of water throughout the day to help with the detoxifying aspect of SierraSil Joint Formula14.

The recommended daily dosage is based on your body weight. For people weighing up to 180 pounds, three capsules are recommended. Four capsules are recommended for those over 180 pounds.

Study Results

It's wise to question the validity of any product claims and marketing ploys. Patients know that there should be scientific testing that backs up any claims made. In the case of SierraSil, the manufacturer's website says that "SierraSil has been subjected to a rigorous level of testing and analysis."

One study published in the Journal of Inflammation concluded that SierraSil alone and in combination with Cat's claw provided relief of osteoarthritis symptoms. The benefits of SierraSil were evident within a week and the safety profile for the supplement was excellent. This study involved 107 participants with mild to moderate knee osteoarthritis. They were assigned to one of four groups: high dose SierraSil (3 grams/day), low-dose SierraSil (2 grams/day), low-dose SierraSil (2 grams/day) plus extract of Cat's claw (100 milligrams/day), or placebo.

Another study investigated how SierraSil worked on human cartilage in the laboratory. The authors concluded that SierraSil can significantly reduce processes associated with cartilage breakdown.
