Analysis

Four capsules provide 1,000 mg calcium, 500 mg magnesium, vitamin D3, 50 mcg vitamin K2, and 3 mg boron. The label lists calcium carbonate plus citrate malate and magnesium citrate plus oxide, though it does not separate the contribution from each form.

These minerals and vitamins cover core bone-maintenance pathways better than the 100 mg lysine and 100 mg horsetail additions. Horsetail lacks species, plant-part, and silica-yield detail, while lysine is far below a focused supplemental amount.

Sixty servings are useful, but four capsules and a high daily cost create a substantial routine burden. The large calcium and magnesium amounts also require users to account for diet, kidney function, and medicine timing.

Who is it for
  • Adults seeking a bone-support capsules
  • Users whose needs match the disclosed ingredient amounts
  • People who can screen ingredient-specific medication and tolerance concerns
Best for
  • Comparing form, dose, and practical value
  • Goal-aligned supplement selection
  • Users who prefer a bone-support capsules

Pros

  • Provides substantial calcium and magnesium
  • Includes vitamin D3 and K2
  • Adds 3 mg boron
  • Sixty-serving supply

Cons

  • Requires four capsules
  • Contains magnesium oxide and calcium carbonate
  • Only 100 mg lysine
  • Horsetail has no silica standardization
  • High serving cost

Warnings

  • Vitamin K2 can interfere with warfarin dose management
  • The 500 mg magnesium amount may cause diarrhea and requires caution with impaired kidney function
  • Calcium and magnesium can reduce absorption of levothyroxine, tetracycline or quinolone antibiotics, and bisphosphonates when taken too close together
  • The 1,000 mg supplemental calcium amount should be considered alongside dietary calcium to avoid excessive total intake

Nutrient quality

75 High impact

Citrate malate, citrate, vitamin D3, vitamin K2, and boron citrate are form strengths. Repeated high mineral entries and small horsetail and lysine amounts create dose imbalance and uncertainty.

Ingredient transparency

74 High impact

Listed active ingredients have specific weights and no proprietary blend hides their doses. Complete use directions and a full other-ingredients list are not included in the supplied facts.

Customer satisfaction

58 Moderate impact

The supplied average rating is strong, and the small review sample limits confidence. No detailed comments are provided to assess repeated complaints or whether experiences match the intended use.

Value for money

56 Moderate impact

Weak dose efficiency or high recurring cost limits practical value. Incomplete form, activity, or use details remain the main value trade-off.

Report overview
Lysine · 100 mg OverallScore44
B- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

Lysine hydrochloride is a stable, well-absorbed form, but the 100 mg amount is much too low for a focused lysine supplement. Reaching a useful amount would require several capsules, and the label data provides no purity grade or sourcing claim. Substantial bone-support nutrients add some formula value, while vitamin K2 requires special attention for people using warfarin.

Horsetail · 100 mg OverallScore32
F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The 100 mg horsetail powder is fully disclosed but provides no silica yield or extract standardization. Its species and plant part are also missing, which limits confidence in botanical identity. Capsule delivery is practical, while the high serving cost weakens value for this small raw-herb amount.

L-Lysine 1000 mg

Solgar
A clearly identified lysine hydrochloride amount provides ten times the original's lysine for a focused lysine goal. The single-active formula is easier to assess, though it does not replace the original's calcium, magnesium, vitamins D and K, or boron.
78 Performance

Target-Mins Magnesium Caps With Silica 300 mg

Country Life
Magnesium paired with 43 mg of horsetail-derived silica offers a more coherent mineral-and-silica focus than the original's low horsetail amount. The split among magnesium forms and horsetail standardization remain unclear, and the formula lacks the original's calcium and bone-support vitamins.
71 Performance

Super Silica Plus

KAL
A substantial horsetail amount, added silica, MSM, and biotin create a more deliberate silica-focused formula than the original's 100 mg horsetail powder. Neither the horsetail nor silica has strong standardization detail, so active quality remains uncertain.
79 Budget

Target-Mins Magnesium Caps With Silica 300 mg

Country Life
Broader mineral support comes at a much lower recurring cost, combining several magnesium forms with 43 mg of horsetail-derived silica. It omits the original's calcium, vitamins D and K, and boron, so it is a more focused magnesium-and-silica choice rather than a complete bone formula.
86 Budget

L-Lysine 1000 mg

AN Amazing Nutrition Amazing Formulas
Focused lysine supplementation costs much less per serving and raises lysine from the original's 100 mg to 1000 mg. It drops the calcium, magnesium, vitamins D and K, and boron, so it fits a lysine priority rather than broad bone support.
79 Budget

Horsetail 500 mg

Swanson
Focused horsetail support comes at a much lower recurring cost and provides 500 mg instead of the original's 100 mg powder. Species, plant-part, and silica-yield details are missing, so the formula is narrower and less informative for bone support.
84 Value

L-Lysine 600 mg

21st Century
A meaningful lysine hydrochloride amount offers a stronger lysine focus and markedly better serving value than the original. The small calcium amount does not make it a full bone-support substitute, but the short formula is easier to assess.
77 Value

Horsetail Grass 450 mg

Nature's Answer
A larger horsetail amount gives substantially more direct collection coverage at a lower recurring cost. Missing species, plant-part, and silica-yield details limit confidence, and the product does not cover the original's wider bone-nutrient profile.
86 Value

L-Lysine 500 mg

Source Naturals
The focused capsule supplies five times the original's lysine amount while offering much stronger serving value. It is a practical choice when lysine is the priority, but it omits the original's mineral and vitamin framework.
