Analysis

The combined horsetail amount is substantial, and identifying an aerial extract provides some useful source information. The capsule remains focused on one structural-support pathway without unrelated additions.

The label references silica but does not state a percentage or elemental silicon amount. Species and extract concentration are also missing, so the larger botanical weight does not guarantee greater active delivery.

It may fit users who want more horsetail material than a basic raw-herb capsule provides. Shoppers comparing potency should favor products that quantify silica rather than relying on extract weight alone.

Who is it for
  • Adults seeking a higher-weight horsetail formula
  • People focused on hair-shaft or nail structure
  • Users who prefer capsules
Best for
  • Combined extract and raw herb
  • Focused botanical use
  • Moderate-cost daily supplementation

Pros

  • Large combined horsetail amount
  • Aerial extract is identified
  • No unrelated active ingredients

Cons

  • Actual silica yield is unknown
  • Latin species is not identified
  • Moderate value for an unstandardized formula

Warnings

  • Horsetail may increase urination and can compound diuretic medicines
  • Long-term use of unstandardized horsetail may affect thiamine status
  • People with kidney or electrolyte problems should seek individual guidance

Nutrient quality

84 Highest impact

A large combined horsetail amount and identified aerial extract support meaningful use. Missing species and silica-yield information limit precise potency assessment.

.

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

68 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

83 Highest impact

A substantial, focused horsetail serving supports good value. Unquantified silica prevents a stronger potency comparison.

Horsetail · 100 mg

Horsetail offers a silica-related pathway that may improve nail strength. The substantial botanical amount is disclosed, but actual silica yield and extract standardization are unclear.

No biotin, collagen, MSM, zinc, or amino acid broadens structural support. The focused formula avoids unrelated ingredients but leaves functional potency uncertain.

C- Goal FitC- Strength of SupportF CoverageC Formula Quality

Horsetail may support hair-shaft strength through its natural silica content, making the formula more relevant to brittleness than to shedding. Direct evidence for improved hair growth is limited.

The combined herb amount is substantial, but the label does not identify the Latin species or quantify the silica yield. Those omissions make the active dose and practical bioavailability difficult to judge.

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 combined aerial-extract and raw-horsetail formula, 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>

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 combined aerial-extract and raw-horsetail formula, 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>

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 combined aerial-extract and raw-horsetail formula, the more specific extract or broader active profile provides a stronger basis for silica, hair, or nail support. The horsetail is not standardized and the silica source lacks absorption detail, which tempers confidence.</p>

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 combined aerial-extract and raw-horsetail formula, 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>

Horsetail Grass 450 mg

Nature's Answer
<p>A focused 450 mg horsetail serving supplies a substantial amount of raw herb with favorable serving value. Compared with the original combined aerial-extract and raw-horsetail formula, it offers a lower-cost or similarly economical way to obtain a more substantial horsetail-focused serving. Species, plant part, and silica yield are not identified, which limits potency comparison.</p>

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 combined aerial-extract and raw-horsetail formula, it offers a lower-cost or similarly economical way to obtain a more substantial horsetail-focused serving. The horsetail species, plant part, and silica yield remain undisclosed, so the main extract cannot be fully compared.</p>

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 combined aerial-extract and raw-horsetail formula, 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>

<p>A very large 1,500 mg horsetail extract amount offers substantial herbal material with favorable serving value. Compared with the original combined aerial-extract and raw-horsetail formula, 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>

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 combined aerial-extract and raw-horsetail formula, the combination of ingredient depth and serving economics creates a more balanced quality-to-value trade-off. No silica yield is stated, and the mixed mineral forms make the central silica benefit less precise.</p>
