HEIGHT+ / THE SCIENCE OF BONE NUTRITION

The science behind HEIGHT+: BonePep® and K2VITAL®

From the remarkable 21-day journey of a developing chick to modern research on BonePep® and K2VITAL®, discover the science and thoughtful nutrition behind HEIGHT+—created to support healthy growing bones.

01 / BONEPEP® · 100 MG PER TABLET

Why was BonePep® developed?

Developed by Japan’s Pharma Foods International, BonePep® was inspired by chick development: a chick develops its skeleton during roughly 21 days of incubation. Researchers then investigated egg-yolk proteins and derived peptides in bone-related biology.

Inspired by a chick’s remarkable development over approximately 21 days, Japanese researchers explored egg-yolk proteins and developed BonePep® using a specialized hydrolysis process. Each HEIGHT+ tablet provides 100 mg of this patented egg-yolk-derived peptide ingredient.
FROM EGG YOLK TO PATENTED PEPTIDES

The egg-yolk story is about specialized extraction

BonePep® starts with egg yolk, then undergoes specialized processing and hydrolysis to create a distinct peptide ingredient—not simply powdered egg yolk. Each HEIGHT+ tablet contains 100 mg BonePep®. The value comes from its specialized peptide processing, not a claim of being nutritionally identical to multiple egg yolks.

Food sources: what does 30 mcg of MK-7 mean?

One cup of 2% milk (~240 mL)~1 mcgMK-4
HEIGHT+ / tablet30 mcgK2VITAL® MK-7

By microgram weight of K2, this is approximately the amount found in 30 cups of milk. MK-4 and MK-7 are different forms; it does not imply equal absorption or effect. Natto is a rich natural source of MK-7; some fermented cheeses contain variable amounts.

A human comparison study still detected MK-7 48 hours after intake, whereas circulating exposure to MK-4 was lower under the study conditions. Detection time does not establish duration of effect.

BONEPEP® / FOOD & SCIENCE

Why not simply eat eggs?

Eggs are nutritious everyday foods, supplying protein and other nutrients. BonePep® starts with egg-yolk protein but is made through specialized hydrolysis into a defined peptide ingredient with its own bone-health research. Eating eggs and choosing a precisely labeled 100 mg serving of BonePep® are different nutritional choices, each with a place.

100 MG / THE RESEARCHED INGREDIENT

What makes 100 mg BonePep® special?

From osteoblast activity and growing-animal skeletal research to bone-turnover and density measures in adult women, studies have explored the potential of egg-yolk-derived peptides. HEIGHT+ provides a clearly labeled 100 mg of branded BonePep® per tablet.

IN VITRO / CELL STUDIES

Cell research: bone formation and resorption

Studies in cultured bone cells reported changes in osteoblast-related activity, ALP, mineralization markers and osteoclast formation. These findings help researchers explore pathways involved in bone formation and renewal.

Young mice: longitudinal bone growth

The manufacturer describes a short four-day study in growing mice reporting changes in tibial longitudinal growth. These findings offer a promising direction for understanding skeletal development.

HUMAN / ADULT STUDY

65 women: six-month bone study

A six-month study involving 65 middle-aged women examined egg-yolk-derived material and bone density/metabolism markers, with positive results on selected measures. The results contribute human clinical data on egg-yolk-derived ingredients and adult bone health.

BonePep® research spans cell mechanisms, growing-animal models, and adult bone-health outcomes—each adding a different perspective on skeletal biology.

2025 CHILDHOOD HEIGHT RESEARCH / VITAMIN K2

New research links vitamin K2 status with children's height

Growing bones need more than calcium. Two observational studies published in 2025, involving 730 and 689 children respectively, found a statistical association between low vitamin K2 status and short stature—highlighting K2 as a nutrient worth understanding during the growing years.

32.4%Normal-stature groupK2 deficiency prevalence in the same study

Both studies were cross-sectional: they found an association, not proof that low K2 causes short stature or that supplementation increases height. They assessed vitamin K2 status, not HEIGHT+ itself.

02 / K2VITAL® · MK-7 · 30 MCG PER TABLET

K2VITAL®: beyond calcium absorption

K2VITAL® is a branded MK-7 vitamin K2 ingredient developed by Kappa Bioscience for a consistent and traceable source. Vitamin D aids intestinal calcium absorption; vitamin K supports osteocalcin carboxylation, which helps osteocalcin bind calcium in bone mineralization. Together, these mechanisms explain the complementary roles of calcium, vitamin D3, and K2 in bone nutrition.

MK-7 is relatively uncommon in typical diets: natto is a notable source. Some aged cheeses contain vitamin K2 in varying forms and amounts; milk and eggs are not major MK-7 sources.
K2VITAL® / EVERYDAY DIET

Why learn about MK-7 even if you eat eggs and drink milk?

Natto is a notable natural source of MK-7, while some aged cheeses contain vitamin K2 in varying forms and amounts. Milk and eggs offer valuable nutrients but are not major MK-7 sources. For families who rarely eat natto, each HEIGHT+ tablet provides a clearly stated 30 mcg of K2VITAL® MK-7.

CALCIUM / D3 / K2

Absorption and use: different roles

Calcium is a key bone mineral; vitamin D3 supports calcium absorption; K2 participates in normal osteocalcin activation and bone mineralization. HEIGHT+ brings these nutrients together with BonePep® as a thoughtful bone-nutrition option for growing years.

ADULT / BIOAVAILABILITY

Human bioavailability and vitamin-K activity

Randomized studies compared synthetic and fermentation-derived MK-7 and reported comparable exposure, with osteocalcin marker changes at studied doses. HEIGHT+ provides a clearly labeled 30 mcg of K2VITAL® MK-7 per tablet.

CHILDREN / 8 WEEKS

55 healthy children: osteocalcin trial

A randomized placebo-controlled study of 55 healthy prepubertal children used 45 mcg MK-7 daily for eight weeks and found improved osteocalcin carboxylation markers. The findings help explain the role of MK-7 in osteocalcin activation during childhood.

CHILDREN / SPECIAL POPULATION

Pediatric bone density: special clinical population

Another study evaluated MK-7 with vitamin D in children receiving leukemia treatment. This study adds another clinical perspective on vitamin K2 and bone-related measures in children.

Solmaz et al. (2021) ↗

Research focus: MK-7 supports osteocalcin activation, an important process in bone metabolism. Each HEIGHT+ tablet contains 30 mcg K2VITAL® MK-7.
