Silica Collagen Builder
Dr. Mercola
Overview
This Dr. Mercola Silica Collagen Builder supplies 10mg of silica per capsule, recommended twice daily for a total of 20mg. While silica is a recognized trace element involved in collagen synthesis and connective tissue health, the dosage provided is significantly lower than what has been studied and shown to be effective in clinical research for benefits related to skin elasticity, hair strength, nail health, or bone mineral density. Furthermore, the product does not specify the form of silica used, which is critical as bioavailability varies greatly among different silica compounds. The claim "To help rebuild collagen" may therefore be an overstatement given the likely underdosing and unspecified form.
The Good
Generally Recognized as Safe (GRAS) Ingredient: Silica is a naturally occurring mineral and considered safe for consumption.
Minimal Side Effects: Given the very low dosage and inert nature, side effects are highly unlikely.
Simple Formulation: Contains only one primary active ingredient, reducing the complexity of potential interactions.
The Bad
Low Dose of Silica: The product provides 10mg of silica per serving (20mg daily), which is significantly lower than doses typically investigated in studies showing benefits for skin, hair, and nail health, which often range from 10-20 mg of elemental silicon (which is approximately 25-50 mg of silica) to hundreds of milligrams of silica.
Lack of Specific Silica Form: The label simply states "Silica" without specifying the form (e.g., orthosilicic acid, colloidal silica, bamboo extract), which can impact bioavailability and efficacy. Living Silica is mentioned as a trademark, implying a specific form, but this is not clarified in the supplement facts.
Limited Evidence for Collagen Building: While silica is involved in collagen formation, the claim "To help rebuild collagen" at this dose and without a specified bioavailable form might be an overstatement of the product's direct effect, especially for rebuilding existing collagen in adults.
Is it for you?
Best For: Individuals seeking to support skin elasticity, hair strength, nail health, and overall connective tissue integrity.
