Who should take Horsetail?

Individuals with brittle nails or weak hair seeking traditional herbal support. Those interested in natural diuretics

The typical dose is 300–900 mg dried horsetail herb daily. Daily for 2–3 months to assess nail/hair benefits

Always consult your doctor before starting any new supplement, particularly if you are on prescription medication or have an existing health condition.

Buying guide for India

When shopping on Amazon.in, prioritise products that clearly state:

• The standardised active compound percentage
• Third-party testing (NSF, USP, or Informed Sport)
• The form of Horsetail (extract vs whole herb vs isolate)
• Vegetarian capsule certification if that matters to you

Generic “natural” or “herbal” labels without standardisation information are a red flag. The price difference between a well-made and a poorly-made Horsetail supplement is often small — the difference in efficacy is not.

Bottom line

Horsetail has Key citations: PMID 28085277 (Mimica-Dukic 2008, silica bone study), PMID 12596850 (Dressler 2016, h for hair-loss. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
