World's First
Sustainable Lactoferrin

Benefits of Lactoferrin

Lactoferrin boosts immunity and regulates an appropriate immune response. Lactoferrin activates immune cells to increase natural immune response and promotes protective immune signals.

Benefits of Lactoferrin

Lactoferrin boosts immunity and regulates an appropriate immune response. Lactoferrin activates immune cells to increase natural immune response and promotes protective immune signals.

Lactoferrin helps regulate iron absorption, distribution, and metabolism throughout the body, ensuring its availability and supporting overall iron balance and health.

Lactoferrin promotes gut health and the microbiome by aiding nutrient absorption and strengthening the intestinal barrier

Lactoferrin modulates inflammation by influencing immune cell activation, reducing pro-inflammatory cytokine production, and supporting balanced immune signaling to prevent excessive inflammatory responses.

Milk's most valuable protein

Milk is full of valuable proteins that pack a nutritional and functional punch. Yet, there is one protein that rises to the top: lactoferrin. Known by TurtleTree as Pink Gold^™, this one-of-a-kind ingredient provides numerous health benefits.

A limited supply

While lactoferrin is already used in supplements and infant formulas today, one big problem remains: the scarce amounts naturally obtainable from milk cannot satisfy the demand as 1 liter contains only 100 mg of lactoferrin.

Precision fermentation technology

For that reason, we've developed LF⁺, the world's first sustainably produced lactoferrin. Compared to traditional lactoferrin, LF⁺ can ultimately be produced more affordably and at a far greater scale, ensuring supply for everybody, everywhere.

The future of nutrition

We envision LF⁺ playing a central role in shaping a new era of functional nutrition, catering to diverse consumer needs, contributing to the well-being of people worldwide, and reducing our footprint on the planet.

LF+® is Perfect For

Vitamins & Supplements

Lactoferrin has been clinically shown to outperform traditional iron supplementation in women with iron deficiency, with fewer gastrointestinal side effects. LF⁺ can be put into many supplement formats like powders, capsules, tablets, and gummies.

Functional Beverages

Functional beverages are meant to go beyond taste. Their goal is to provide the benefits needed to succeed each day. Lactoferrin can provide immunity, gut health, and iron regulation benefits in drinks. LF⁺ remains thermostable, limiting denaturing during production when added to functional beverages to enhance nutritional benefits.

Sports Nutrition

LF⁺ is the perfect way to upgrade sports nutrition. By keeping iron levels elevated, lactoferrin improves muscle recovery, minimizes lactic acid build-up in muscles, reduces exercise-induced fatigue, and supports immunity and gut health.

Skincare and Cosmetics

There's a powerful connection between your body's iron regulation and the health of your skin.

Plant-Based Food & Beverages

Lactoferrin bridges the functional gap between conventional and plant-based products. LF⁺ is an animal-free and vegetarian-certified lactoferrin, making it a perfect addition to plant-based products for functional benefits.

The Science

Why LF+® Works for Your Product

Only rbLF with FDA "No Questions" GRAS

LF+ has achieved FDA GRAS status — the gold standard for food ingredient safety in the U.S. This means it has been rigorously reviewed and recognized as safe for use in food and beverage products.

Commercial Scale

Our precision fermentation platform enables consistent, large-scale production of LF+, ensuring reliable supply for global food and nutrition brands.

Maintains Ferritin Levels Better Than bLf

Clinical studies show that LF+ maintains serum ferritin levels more effectively than bovine lactoferrin, supporting better long-term iron storage and bioavailability.

Improved Digestion Kinetics

LF+ demonstrates enhanced gastric digestion behavior compared to bovine lactoferrin, resulting in better nutrient absorption and gastrointestinal compatibility.

Enhanced Thermal and pH Stability

LF+ retains its structural integrity and bioactivity across a wider range of temperatures and pH levels — ideal for processed foods, beverages, and supplements.

Vegan Certified

Produced through precision fermentation without any animal-derived inputs, LF+ is fully vegan-certified — making it suitable for plant-based and clean-label products.
