Marine nutrients. Advanced delivery. Daily support.

A comprehensive marine-based formula combining fucoidan from Okinawan Mozuku, Ascophyllan from North Atlantic algae, lactoferrin, and four nutrient-rich Japanese seaweeds — nori, hijiki, wakame and kombu.

Fucoidan and Ascophyllan are bioactive marine polysaccharides studied for their immune-modulating, antioxidant and anti-inflammatory properties, while the seaweed blend provides naturally occurring minerals, antioxidants, fiber and polysaccharides.

The formula uses liposomal nanoencapsulation technology to improve the stability and bioavailability of fucoidan and help protect it from degradation during digestion.

Japanese marine tradition combined with modern liposomal technology.

Looking to improve your skin, joint, and bone health? Collagen tripeptide might just be the supplement for you. This unique form of collagen supplement is composed of a short chain of three specific amino acids that are crucial for the formation and upkeep of connective tissues in the body.

What sets collagen tripeptide apart from traditional collagen supplements is its unique structure, which allows for better absorption and utilization by the body. Its small molecular size enables it to be absorbed directly by the intestinal tract, delivering its benefits more effectively to the body’s collagen-affiliated organs and tissues.

Studies have consistently shown that collagen tripeptide offers numerous benefits, including improved skin health, joint health, and bone health.

In fact, one study published in the Journal of Cosmetic Dermatology found that after just 12 weeks of supplementation, participants who consumed collagen tripeptide had significantly higher skin elasticity levels compared to those who consumed a placebo.

Another study published in the Journal of Agricultural and Food Chemistry found that collagen tripeptide was absorbed 18 times faster than traditional collagen supplements. And a study published in the Journal of Nutrition and Metabolism found that participants who consumed collagen tripeptide had significantly higher levels of type I collagen in their skin compared to those who consumed a placebo.

So if you’re looking for a reliable way to boost your collagen levels and improve your overall health and well-being, collagen tripeptide may be the answer.
With numerous studies supporting its effectiveness, it’s a supplement you can trust.

Liposomal iron supplement for daily iron support

Yotsuba Japan updated iron formula now uses next-generation liposomal iron — a microencapsulated form of iron enclosed within a phospholipid structure.

This delivery format is designed to support better stability, controlled release and improved absorption efficiency, while being gentler on the stomach and helping reduce the typical metallic odor of iron.

For people looking for a gentle iron supplement, liposomal iron, high bioavailability iron, ferritin support or daily iron support - this formula was created for comfortable, consistent intake.

Healthy-looking skin depends not only on surface care, but also on how cells exchange biological signals, maintain energy and support renewal over time.

Exosomes are extracellular vesicles involved in cell-to-cell communication. They carry proteins, lipids and nucleic acids, helping cells transfer information and coordinate their activity.

The formula uses PUA Exosome® technology with bioactives derived from placenta, umbilical cord and amnion.

Its key feature is concentration: 218 billion exosomes per gram.

Three biological sources work together in the formula:

Placenta — rich in amino acids, enzymes, vitamins and growth-factor related components.

Umbilical Cord — naturally high in moisture-supporting compounds such as hyaluronic acid and chondroitin sulfate.

Amnion — a source of cytokines and growth factors, including EGF, FGF and GDF-11.

Together, these components are designed to support the biological processes behind:

Hydration & Skin Comfort
for smoother, more supple-looking skin.

Firmness & Elasticity
for skin structure, resilience and a firmer-looking appearance.

Cellular Energy
to support inner vitality and skin renewal.
