Analysis

The substantial horsetail amount provides a focused botanical source of naturally occurring silica. A capsule format keeps the formula simple and easy to use.

The main limitation is disclosure rather than quantity. Without a named species, plant part, or measured silica yield, the listed herb weight cannot confirm how much active silicon is delivered.

It fits shoppers who want an inexpensive, single-ingredient horsetail product for hair or nail structure. Those seeking a predictable silicon dose or broader nutrient support should choose a standardized formula.

Who is it for
  • Adults seeking a simple horsetail supplement
  • People focused on hair-shaft or nail structure
  • Budget-conscious users comfortable with an unstandardized herb
Best for
  • Single-ingredient supplementation
  • Low ongoing serving cost
  • Simple capsule use

Pros

  • Substantial horsetail amount
  • Focused one-ingredient formula
  • Low serving cost

Cons

  • Silica yield is not stated
  • Species and plant part are not identified
  • Does not cover other hair or nail nutrients

Warnings

  • Horsetail may increase urination, so use cautiously with diuretics or when dehydrated
  • Long-term use of unstandardized horsetail may affect thiamine status
  • People with kidney or electrolyte problems should confirm suitability before use

Nutrient quality

76 High impact

A substantial raw-herb amount provides a plausible horsetail foundation. Missing species, plant-part, and silica-yield details keep active quality uncertain.

.

Ingredient transparency

74 High impact

Active amounts are clearly listed and no proprietary blend hides the supplied doses. Missing daily directions, excipients, and some form or potency details keep disclosure incomplete.

.

Customer satisfaction

69 High impact

A strong supplied average is backed by a substantial review base. Specific review comments were not provided, so repeated complaints and purpose-specific experiences cannot be assessed.

.

Value for money

91 Highest impact

A substantial raw-herb serving and very favorable cost create good practical value. Unknown silica yield prevents a precise comparison with standardized products.

Horsetail · 450 mg

Horsetail may support nail plate integrity through naturally occurring silica, and the 450 mg raw-herb amount is clearly stated. Actual silica or elemental silicon delivery cannot be determined from the label.

Species, plant part, extract strength, and standardization are missing, which limits confidence in both quality and evidence. The focused capsule avoids filler actives but does not cover biotin, structural protein, or amino acid pathways.

F Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyA+ Value

The substantial raw horsetail amount is clearly disclosed, but the label gives no extract concentration or active silica yield. A capsule should release the plant powder efficiently, while absent species and plant-part details limit confidence in source quality. The low serving cost creates good value for raw herb, although the actual mineral contribution cannot be verified.

Horsetail 400 mg

Solaray
<p>A 400 mg aerial extract plus 100 mg of additional horsetail provides a more concentrated and better-described herbal base. Compared with the original 450 mg raw-horsetail capsule, the more specific extract or broader active profile provides a stronger basis for silica, hair, or nail support. The species and actual silica yield are still absent, so the improvement is meaningful but not fully quantified.</p>
82 Performance

Horsetail Extract Alcohol-Free

Nature's Answer
<p>A 560 mg Equisetum arvense aerial-parts extract gives clearer species and plant-part disclosure in a focused liquid. Compared with the original 450 mg raw-horsetail capsule, the more specific extract or broader active profile provides a stronger basis for silica, hair, or nail support. The label does not state silica yield, leaving the delivered active amount uncertain.</p>
80 Performance

Bone-Sil

Terry Naturally
<p>An 800 mg Equisetum arvense aerial extract provides the strongest species-identified horsetail amount among the focused options. Compared with the original 450 mg raw-horsetail capsule, the more specific extract or broader active profile provides a stronger basis for silica, hair, or nail support. Silica yield is not quantified, and the lightly dosed vitamin D adds limited support.</p>
79 Budget

Horsetail 500 mg

Swanson
<p>A focused 500 mg horsetail-herb serving offers substantial raw herb in a very economical format. Compared with the original 450 mg raw-horsetail capsule, it offers a lower-cost or similarly economical way to obtain a more substantial horsetail-focused serving. Species, plant part, and silica yield are still missing, so active strength remains uncertain.</p>
80 Budget

Silica Complex

NOW
<p>A 575 mg horsetail extract adds calcium, chelated zinc, manganese, and boron while maintaining excellent serving value. Compared with the original 450 mg raw-horsetail capsule, it stays near the low-cost end while adding formulation depth that may improve practical value. The horsetail species, plant part, and silica yield remain undisclosed, so the main extract cannot be fully compared.</p>
74 Budget

Super Silica Complex

Futurebiotics
<p>A 286 mg horsetail leaf extract is paired with calcium, magnesium, zinc, and boron in a cost-conscious mineral formula. Compared with the original 450 mg raw-horsetail capsule, it stays near the low-cost end while adding formulation depth that may improve practical value. No silica yield is stated, and the mixed mineral forms make the central silica benefit less precise.</p>
82 Value

Target-Mins Magnesium Caps With Silica 300 mg

Country Life
<p>A clearly listed 43 mg horsetail-derived silica amount adds useful active detail alongside several magnesium forms. Compared with the original 450 mg raw-horsetail capsule, the combination of ingredient depth and serving economics creates a more balanced quality-to-value trade-off. The blend includes magnesium oxide and does not show how the magnesium total is divided among forms.</p>
79 Value

Silica

Alta Health Products
<p>A very large 1,500 mg horsetail extract amount offers substantial herbal material with favorable serving value. Compared with the original 450 mg raw-horsetail capsule, the combination of ingredient depth and serving economics creates a more balanced quality-to-value trade-off. Species, plant part, extract concentration, and silica yield are missing, so the large label amount does not establish active potency.</p>
81 Value

Super Silica Plus

KAL
<p>A 600 mg horsetail aerial extract plus 20 mg colloidal silica, MSM, and biotin broadens support for hair and nails. Compared with the original 450 mg raw-horsetail capsule, the combination of ingredient depth and serving economics creates a more balanced quality-to-value trade-off. The horsetail is not standardized and the silica source lacks absorption detail, which tempers confidence.</p>
