Analysis

Boron as aspartate, citrate, and glycinate provides a varied mineral complex for focused boron supplementation. The listed 3 mg amount is practical if it represents the total serving amount.

Using three forms is thoughtful, and all named ingredients are disclosed. Repeated 3 mg entries make the total boron amount ambiguous, while 25 mg of riboflavin adds little to the focused purpose.

It fits adults seeking a modest boron supplement who can confirm the label total. Users wanting a single clearly stated boron dose should verify the serving information first.

Who is it for
  • adults seeking a modest boron supplement who can confirm the label total
  • Adults seeking the product’s stated nutrient profile
Best for
  • The listed 3 mg amount is practical if it represents the total serving amount
  • Users wanting a single clearly stated boron dose should verify the serving information first

Pros

  • Uses three boron forms
  • Focused mineral formula
  • Includes riboflavin
  • Capsule format is simple

Cons

  • Repeated boron entries create dose ambiguity
  • Riboflavin amount is unrelated to the main purpose
  • Not a broad bone-mineral formula
  • Requires label verification

Warnings

  • Confirm whether the repeated 3 mg entries describe one total dose or separate amounts before use.
  • Boron should be reviewed carefully during pregnancy or breastfeeding because supplemental safety data are limited.
  • People with significant kidney impairment should seek individual guidance before concentrated mineral supplementation.

Nutrient quality

66 High impact

The boron forms are favorable and the intended amount appears practical. Ambiguous cumulative dosing and unrelated high riboflavin weaken precision.

.

Ingredient transparency

73 High impact

Most active amounts are listed, but duplicated form entries make some totals difficult to interpret. Complete directions and non-active ingredients are not supplied.

.

Customer satisfaction

71 High impact

The supplied average is strong, and the rating count is very large. Specific firsthand feedback is absent, so repeated complaints and purpose fit cannot be assessed.

.

Value for money

90 Highest impact

The very low serving cost creates strong value for the disclosed core formula. Minor dosing or form limitations do not outweigh the affordability.

Boron · 3 mg

Boron supports mineral metabolism and may contribute to bone and joint foundations, while riboflavin supports energy metabolism. The formula is relevant to general wellness but narrower and less established than core vitamin or mineral combinations.

The 3 mg boron amount is well aligned for ongoing use. Three named organic forms improve confidence, although the label data do not clearly state how the amount is divided among them.

Boron · 3 mg

Boron may support free testosterone by influencing SHBG and related hormone markers. Small human trials are encouraging, although the evidence base remains narrower than for correcting vitamin or mineral deficiencies.

The 3 mg amount is well aligned with common long-term supplemental use. Aspartate, citrate, and glycinate forms are named clearly, though their individual contributions are not separated.

Report overview
B- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyA+ Value

A triple complex of aspartate, citrate, and glycinate provides clearly named organic forms. The stated 3 mg serving fits the preferred long-term range, although the extracted form entries leave their individual contributions unclear. Boron-specific cost efficiency is excellent.

D- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyA+ Value

The 25 mg serving reaches the moderate-support range at very good value. Standard riboflavin requires conversion before use, while the capsule should dissolve efficiently. The label data show no artificial colors, flavors, or synthetic sweeteners.
