Silica Complex
A trace mineral that supports collagen production for healthy skin, hair, and nails.
Also known as: Silicon Dioxide • Orthosilicic Acid
Overview
Silica is a compound made of silicon and oxygen. It is the third most abundant trace element in the human body and is essential for the synthesis of collagen and elastin. Collagen provides strength and structure to skin, while elastin allows it to be flexible. As we age, silica levels decline, which can contribute to signs of aging. Supplementing with a bioavailable form of silica, like that from bamboo or horsetail extract, can support skin elasticity, hair strength, and nail health.
Key Benefits
Enhances Skin Elasticity
Silica is crucial for activating the enzymes that hydroxylate collagen, improving skin strength and elasticity.
Strengthens Hair
It delivers essential nutrients to the hair follicles and may help reduce hair thinning.
Improves Nail Quality
Silica can strengthen brittle nails and reduce splitting.
Dosage & How to Take
Doses are typically based on the elemental silicon content, ranging from 10-30 mg per day.
| Purpose | Dose | Notes |
|---|---|---|
| Skin, Hair, and Nails | 10-30 mg/day of silicon | Look for standardized extracts of bamboo or horsetail. |
Best Time to Take
Can be taken anytime.
With or Without Food
Not necessary.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Bamboo Extract | Good | High silica content | A rich natural source, often standardized to 70% silica. |
| Horsetail (Equisetum arvense) | Moderate | Traditional use | Contains about 7% silica. |
| Choline-Stabilized Orthosilicic Acid (ch-OSA) | Very High | Clinically proven benefits | A highly bioavailable and effective form. |
Side Effects & Safety
Common
- Generally well-tolerated.
Rare
- Long-term use of horsetail may lead to thiamine (Vitamin B1) deficiency due to the enzyme thiaminase. Look for thiaminase-free products.
Contraindications
- Individuals with kidney disorders should consult a doctor before supplementing with silica.
Interactions
