How it is used: Commonly used in beauty, bone, joint, and urinary wellness supplements, horsetail is often chosen for promoting tissue resilience and supporting fluid balance.
Natural sources and supplement forms: Horsetail grows in moist soils throughout the Northern Hemisphere. Supplements use the dried above-ground parts in powders, capsules, tinctures, or concentrated extracts standardized for silica content.
Why it appears in supplement formulas: Its natural plant-based silica and trace minerals make horsetail a popular choice for those wanting to support connective tissues, strengthen hair and nails, and promote urinary tract health.
What to know before use: Horsetail contains thiaminase, an enzyme that can reduce vitamin B1 (thiamine) if used long-term or at high doses; seek medical guidance before prolonged use or combining with medications.
Horsetail: A Living Fossil Still Used Today
Horsetail, also known as Equisetum, is a unique plant that has existed for over 100 million years, earning it the nickname 'living fossil.' It is rich in natural silica, a mineral found in very few plants, which makes horsetail a popular choice in supplements for those seeking plant-based sources of this element in modern formulations.
