Analysis

The clearly stated horsetail amount gives users a substantial raw-herb serving in a straightforward capsule. Its lean design and low serving cost are the strongest practical advantages.

The label does not identify the species, plant part, extract strength, or silica yield. Raw herb weight therefore cannot show how much elemental silicon reaches the user.

It may suit people seeking inexpensive support for nail plate or hair-shaft structure. Users prioritizing reliable potency should look for measured silica or a standardized extract.

Who is it for
  • Budget-conscious horsetail users
  • Adults focused on nail or hair structure
  • People who prefer a simple capsule
Best for
  • Low-cost daily use
  • Single-ingredient supplementation
  • Users comfortable with raw herb

Pros

  • Substantial listed herb amount
  • Simple capsule format
  • Low serving cost

Cons

  • No quantified silica yield
  • Species and plant part are missing
  • Limited to one structural pathway

Warnings

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

Nutrient quality

76 High impact

A substantial raw-herb amount gives the formula a simple, plausible foundation. Absent species, plant-part, and silica 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

72 High impact

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

.

Value for money

94 Highest impact

A substantial raw-herb amount and very low serving cost create strong value. Unknown silica yield remains the main uncertainty in category comparison.

Horsetail · 500 mg

Horsetail may contribute silica for nail plate integrity, and the 500 mg raw-herb amount is clearly listed. No silica percentage or elemental silicon yield is supplied, so active dosing remains unknown.

Missing species, plant part, extract strength, and standardization weaken confidence in ingredient quality. The focused capsule avoids unrelated actives but leaves biotin, structural protein, and amino acid pathways uncovered.

The substantial raw-herb dose offers a straightforward horsetail serving in an easy-release capsule. Missing silica standardization, mineral yield, Latin species, and plant-part details limit confidence in active quality. Its exact herb weight and low serving cost still make it economically attractive for users comfortable with an unstandardized product.

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 500 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 500 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 500 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>
77 Budget

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 500 mg raw-horsetail capsule, the supplied data do not establish a lower cost, but the ingredient design adds useful value near the low-cost end of the candidate set. Species, plant part, and silica yield are not identified, which limits potency comparison.</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 500 mg raw-horsetail capsule, the supplied data do not establish a lower cost, but the ingredient design adds useful value near the low-cost end of the candidate set. The horsetail species, plant part, and silica yield remain undisclosed, so the main extract cannot be fully compared.</p>
73 Budget

Horsetail Grass 440 mg

Nature's Way
<p>A simple 440 mg horsetail serving keeps the formula focused and the ongoing cost low. Compared with the original 500 mg raw-horsetail capsule, the supplied data do not establish a lower cost, but the ingredient design adds useful value near the low-cost end of the candidate set. The source and silica yield are not disclosed, so the label cannot confirm active silica exposure.</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 500 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 500 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 500 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>
