Under the guidance of the "Healthy China" strategy, the health industry has entered a golden era of vigorous development. As consumers' demands for health management become increasingly sophisticated, the functional food market is expanding at an astonishing speed. From safeguarding the brain health of the elderly to meeting the antioxidant needs of young people, and from cardiovascular care to overall body function regulation, a health revolution centered around "super ingredients" is quietly unfolding. This article will explore the star ingredients reshaping the functional food landscape, uncovering the scientific mysteries and market potential behind them.
I. The Protective Roles of PQQ and
Phosphatidylserine
In today's high-pressure lifestyle, brain health has become a major concern for people of all ages. Whether it's office workers burning the midnight oil or middle-aged and elderly individuals aiming to maintain cognitive function, everyone is seeking effective ways to protect their brains.
(1) PQQ: The "Youth Guardian" of Mitochondria
Pyrroloquinoline quinone disodium salt (PQQ), known as the "mitochondrial optimizer," is revolutionizing our understanding of brain aging with its unique biological properties. This active substance, commonly found in foods such as natto and green tea, not only acts directly on key mitochondrial enzymes to enhance energy metabolism efficiency but also functions as a "cellular scavenger." It can catalyze 20,000 cycles of antioxidant reactions, which is 5,000 times more effective than vitamin C, repairing damaged mitochondria and promoting the generation of new ones.
Scientific Evidence: Long-term oral intake of PQQ by the elderly has been shown to significantly slow down cognitive decline. Studies indicate that it can improve attention and working memory by 23%. Currently, PQQ has been approved as a new food ingredient in China, the United States, the European Union, and other regions. It is widely used in brain health supplements, functional beverages, and special medical foods, emerging as a rising star in the field of anti-brain-aging.

Phosphatidylserine: The "Wisdom Nutrient" of Cell Membranes
Phosphatidylserine (PS), although not a well-known component, is a core constituent of brain nerve cell membranes. Fifty percent of the dry weight of human brain tissue consists of phospholipids, and PS accounts for 22% of brain nerve cells. As a "brain nutrient" extracted from natural soybeans, PS safeguards brain health through three main mechanisms:
- Cognitive Improvement: It helps improve age-related cognitive decline, enhancing mental agility.
- Memory Enhancement: PS strengthens the activity of nerve growth factors, contributing to the consolidation of long-term memory.
- Stress Relief: By regulating neurotransmitter balance, it alleviates anxiety and improves psychological resilience.
In terms of regulations, China listed PS as a new food ingredient as early as 2010, with a daily intake limit of ≤ 600mg. Its application in senior milk powder and cognitive health supplements has formed a mature market, expanding from the "silver economy" to the "workplace health" sector.
II. The Heart-Protecting Functions of Vitamin K2 and Natto Lyophilized Powder
Data from the China Cardiovascular Health and Disease Report is concerning: cardiovascular disease ranks first among causes of death in both urban and rural areas. With the aging of the population, the market for cardiovascular health ingredients is experiencing explosive growth.
(1) Vitamin K2: The "Precision Navigator" of Calcium Metabolism
Vitamin K2 is not a single component; its family members MK-4 and MK-7 are particularly important. MK-4 mainly comes from animal livers, while MK-7 is abundant in natto. As a "vascular calcification terminator," it protects the cardiovascular system through two mechanisms:
- Correcting Calcium Distribution: It guides calcium to deposit in bones, reducing the formation of calcium plaque in blood vessels.
- Vascular Purification: Vitamin K2 activates matrix GLA protein, which can absorb excess calcium in blood vessels, curbing the root cause of atherosclerosis.
Notably, vitamin K2 also plays an important role in bone health. By promoting osteocalcin carboxylation, it enhances bone mineralization efficiency and reduces the fracture risk by 35% in postmenopausal women. Currently, approved as a nutritional fortifier in China, the U.S., the EU, and other regions, it is mainly used in functional dairy products and bone health supplements.
(2) Natto Lyophilized Powder: The "Biological Missile" Against Thrombi
Natto lyophilized powder, processed through -40°C vacuum freeze-drying, preserves the activity of nattokinase. This serine protease, known as the "vascular scavenger," acts like a biological missile, precisely identifying and decomposing fibrin thrombi while activating the body's own fibrinolytic system to improve blood circulation.
Application Scenarios: In South Korea, nattokinase has obtained FDA functional food certification, with a maximum daily intake of 100mg. In China, it is used as an ingredient in health products such as solid beverages and capsules. With the rise of preventive medicine, natto lyophilized powder is transitioning from professional health care to daily dietary supplementation.
III. The Anti-Aging Properties of Lycopene and Sodium Hyaluronate
The deep integration of the beauty economy and health management has stimulated diverse demands for antioxidant ingredients. From achieving beauty from within to full-body cellular anti-aging, this "golden pair" is redefining the consumption scenarios of functional foods.
(1) Lycopene: The "King of Antioxidants" in the Plant Kingdom
As the "antioxidant champion" of the carotenoid family, lycopene quenches singlet oxygen 3.2 times more effectively than β-carotene and 100 times more than vitamin E. This natural red pigment not only gives tomatoes their vibrant color but also serves as a "cellular bodyguard" in humans:
- Prostate Protection: Clinical studies show that a daily intake of 15mg of lycopene can reduce the risk of prostate cancer by 21%.
- Vascular Shield: It inhibits the oxidation of low-density lipoprotein, reducing the incidence of atherosclerosis.
- Skin Anti-Aging: Lycopene reduces UV-induced skin damage by scavenging free radicals.
From ketchup to soft capsules, and from food colorants to nutritional supplements, lycopene has become a favorite in the global food industry due to its comprehensive health benefits.
(2) Sodium Hyaluronate: The Age-Defying "Hydration Code"
As hyaluronic acid expands from the field of medical aesthetics to food, sodium hyaluronate (HA) has launched a new era of oral beauty. This glycosaminoglycan, naturally present in joint synovial fluid and the skin's dermis layer, has a remarkable "thousand-fold water-locking" ability:
- Skin Hydration Magic: Oral intake of HA increases dermal water content, improving skin dryness and flakiness, and enhancing skin radiance by 40%.
- Joint Lubrication Expert: It acts as a natural shock absorber for articular cartilage, relieving joint discomfort caused by exercise-induced wear.
- Gut Microbiome Regulator: By enhancing the intestinal mucosal barrier function and regulating gut flora, it protects digestive health.
After China approved HA for general food use in 2021, innovative products such as hyaluronic acid drinking water and beauty oral liquids quickly emerged, making "internal nourishment and external care" a new health consumption trend.
IV. Future Trends in Functional Food Ingredients: Precision, Complexity, and Contextualization
From single components to complex formulations, and from preventive medicine to precision nutrition, the research and development of functional food ingredients are evolving in three main directions:
- Targeted Precision: Combinations like PQQ and PS for brain health, or vitamin K2 and calcium for bone health, aim to achieve more precise health effects.
- Contextual Segmentation: Customized solutions, such as "anti-fatigue & anti-aging packs" for night owls or "joint repair combos" for athletes, cater to the specific needs of different consumer groups.
- Cutting-Edge Technology: Advanced techniques such as microbial fermentation and supercritical extraction will be increasingly used to improve the quality and functionality of ingredients.
