Analysis

Three capsules provide 400 mg calcium from citrate and malate, vitamin D3, vitamin K1, MK-7, and several trace minerals. Ipriflavone adds a distinct bone-oriented compound, reinforcing that the formula is not primarily designed for hair or nails.

Magnesium is only 49 mg, boron remains below 1 mg, and 9 mg bamboo silica is not standardized for elemental silicon. Repeated vitamin D and calcium entries can also make shared totals look larger than they are.

Seventy servings give a moderate supply, but the three-capsule routine is costly. A simpler targeted silicon product would better match hair and nail goals, while a bone user must consider vitamin K and ipriflavone context.

Who is it for
  • Adults seeking a bone formula with ipriflavone
  • Users who need calcium plus vitamins D and K
  • People whose prescriber has reviewed vitamin K use
Best for
  • Bone-mineral support
  • Calcium citrate-malate intake
  • Vitamin K1 and K2 coverage

Pros

  • 400 mg calcium from useful forms
  • Includes vitamin D3, K1, and MK-7
  • Zinc picolinate and copper glycinate
  • 70 servings

Cons

  • Three capsules per serving
  • Only 49 mg magnesium
  • Bamboo silica is not standardized
  • Weak fit for hair and nail goals

Warnings

  • Vitamin K1 and K2 can interfere with warfarin dose control
  • The calcium serving warrants review for kidney-stone risk or medically restricted calcium intake
  • Ipriflavone is a pharmacologically active isoflavone and should be reviewed alongside prescription medicines

Nutrient quality

73 High impact

The formula offers partial support but has a dose or purpose-alignment limitation. Form uncertainty or weak secondary amounts reduce confidence in its practical contribution.

Ingredient transparency

81 Highest impact

Most active amounts are shown, but duplicated form entries make dose allocation less clear. Full use directions and a complete inactive-ingredient list are also not supplied.

Customer satisfaction

60 Moderate impact

The aggregate satisfaction signal is strong and the supplied volume is limited. No specific experience details are supplied to assess repeated complaints or purpose-related outcomes.

Value for money

51 Moderate impact

The core actives provide some quality, but serving value is only modest or weak. Limited targeting, uncertain forms, or a heavy serving reduce competitiveness.

Silicon · 9 mg

Bamboo silica and zinc provide a modest link to nail structure and growth. The formula is primarily designed for bone health and lacks biotin, collagen, or sulfur amino acids.

Silica supplies only a maintenance amount of elemental silicon, while zinc picolinate is well absorbed. Vitamin K can oppose warfarin and related vitamin K antagonists, so users of those medicines need consistent intake and clinical guidance.

Bamboo-derived silica is a useful botanical source but lacks stated high-silica standardization. Nine milligrams of silica provides about 4.2 mg of elemental silicon in the maintenance range. The serving cost is poor for a maintenance dose without standardized source quality.

Beauty - Bones - Joints

BioSil
<p>A more capable ingredient profile provides 5 mg of silicon as choline-stabilized orthosilicic acid. Compared with the original’s bone-focused blend with 9 mg bamboo silica, it uses a clearly identified, stabilized silicon form with strong alignment to hair and nail goals.</p>

Living Silica Mineral Based Collagen Booster

Orgono
<p>A more capable ingredient profile provides 22.5 mg of silicon as monomethylsilanetriol. Compared with the original’s bone-focused blend with 9 mg bamboo silica, it provides a meaningful amount of a well-defined, absorbable silicon form in a focused formula.</p>

Gelatin & Silicon

Swanson Premium Brand
<p>A lower serving cost still provides 20 mg of silicon aminoate with 1.08 g of gelatin. Compared with the original’s bone-focused blend with 9 mg bamboo silica, this option keeps a meaningful silicon amount and adds gelatin for structural protein support.</p>
