The key ingredient of fucoidan extract is a nutritional polysaccharide derived from various species of brown seaweeds and some marine mollusks. This extract has different types based on its source and concentration.
They include:
Fucus vesiculosus
Commonly referred to as bladderwrack, this seaweed has been used since ancient times. This source is one of the most popular sources of fucoidan owing to its wide availability. It contains fucoidan in variable concentrations in its fronds.
Ascophyllum nodosum
This seaweed is commonly found along the coasts of the North Atlantic Ocean. It is also known as rockweed or slippery weed. Ascophyllum nodosum has been known to contain high concentrations of fucoidan.
Saccharina japonica
This type of brown seaweed is widely known as kombu. In Japanese cuisine, it is used to make dashi (broth). It is a traditional source of fucoidan.
Undaria pinnatifida
This seaweed is commonly known as wakame and is used in miso soup and salads. Undaria pinnatifida is a rich source of fucoidan supplements.
Laminaria kelp
These are large brown seaweeds that are part of the family Laminariaceae. They are also known as kelp and are a common source of fucoidan due to their high content.
Sphaerococcus tessellatus
This is a lesser-known seaweed that grows in rocky intertidal zones. It is known to contain fucoidan but is commonly extracted for its fucoidan content.
Fucus spiralis
Commonly called spiral wrack, this is a species of brown seaweed in the family Fucaceae. It grows in rocky intertidal zones of the North Atlantic. It contains fucoidan powder in its fronds and is often overlooked compared to bladderwrack.
Fucoidan extract is a versatile compound that can be incorporated into wellness products. This is largely because of its numerous benefits. Below are some common uses of the fucoidan extract:
Nutritional supplements
Fucoidan is often combined with other beneficial supplements like collagen and spirulina. The aim is to create a synergistic effect that promotes overall health. Collagen and fucoidan together can help boost skin elasticity, hydration, and regeneration. This can help defer aging and help keep the skin in tip top condition.
Immune support
Fucoidan is known to stimulate immune cell activity. People who want to boost their immunity or reduce the risk of getting sick normally use supplements containing fucoidan.
Weight management
Fucoidan is sometimes included in weight loss products. This is because it helps the body feel fuller for longer. Additionally, when combined with other supplements like green tea extract, fucoidan may enhance fat oxidation and metabolism.
Detoxifying effects
Fucoidan’s potential ability to support liver function and promote the elimination of toxins makes it a common ingredient in detox supplements. Manufacturers normally add fucoidan to detox shakes and capsules for its combined effects with other ingredients like milk thistle and dandelion root.
Gut health
Fucoidan can promote a healthy gut lining and support the growth of beneficial gut bacteria. It is therefore included in probiotic supplements for enhanced digestive health.
Antioxidant and anti-inflammatory support
Fucoidan’s rich antioxidant content and its potential anti-inflammatory effects are useful for individuals looking to combat oxidative stress. This makes it popular in combination with other antioxidants like vitamin C and elderberry.
Skin care products
Fucoidan is included in creams and serums that aim to provide hydration, reduce redness, and promote skin healing. Its anti-aging properties also make it useful in products targeting mature skin.
Post-workout recovery
Fucoidan’s potential to reduce inflammation and muscle soreness after intensive workouts makes it a key ingredient in post-workout supplements. Athletes and fitness enthusiasts who are looking to enhance recovery often use shakes with fucoidan and other recovery-supporting ingredients like branched-chain amino acids (BCAAs). This helps reduce muscle soreness and fatigue.
Fucoidan extract offers numerous health benefits. They are prided in its rich content of polysaccharides, vitamins, and minerals. Some of the key benefits of fucoidan extract include:
Immune system support
Fucoidan is known to stimulate the activity of immune cells such as natural killer (NK) cells and macrophages. These cells are responsible for identifying and destroying pathogens and diseased cells. This boost in immune activity helps the body defend itself against infections and illnesses more effectively than it normally does.
Anti-cancer properties
Extensive research has shown that fucoidan may inhibit the growth of cancer cells. It does this by inducing apoptosis (programmed cell death) in tumor cells while leaving healthy cells unharmed. Fucoidan also slows down tumor progression and metastasis. It does this by blocking the formation of new blood vessels that feed tumors.
Anti-inflammatory effects
Fucoidan’s ability to reduce inflammation throughout the body makes it beneficial for people with chronic inflammatory conditions. It reduces inflammation by inhibiting pro-inflammatory cytokines and mediators.
Antiviral and antibacterial properties
Fucoidan has been found to possess antiviral properties by preventing viruses from entering and infecting healthy cells. It may be particularly effective against certain viruses such as the herpes virus and influenza. Its polysaccharide-rich composition creates a viscous environment that inhibits viral entry and shedding. Fucoidan also demonstrates antibacterial activity by disrupting the cell walls of harmful bacteria. This leads to their death.
Gut health and digestive support
Fucoidan’s ability to promote the growth of beneficial gut bacteria and its potential to help heal and protect the gut lining makes it useful for digestive health. It can alleviate conditions like irritable bowel syndrome (IBS) and promote a healthy microbiome.
Blood sugar regulation
Fucoidan may help moderate blood sugar levels and improve insulin sensitivity. This makes it potentially beneficial for people at risk of diabetes. This property together with its effects on gut health could help in managing blood sugar levels and reducing sugar spikes. This is particularly useful for diabetic or pre-diabetic individuals.
Rich in antioxidants
Fucoidan contains numerous antioxidants that scavenge free radicals in the body. These are unstable molecules that cause oxidative stress and damage to cells. By neutralizing them, fucoidan helps protect against age-related diseases, supports overall cellular health, and may lower the risk of chronic conditions like cardiovascular disease.
Store in a cool, dry place
Fucoidan is sensitive to heat and moisture. Avoid storing it in places like the kitchen or bathroom where temperature and humidity levels fluctuate frequently. Instead keep it in a cool, dry place with a more stable temperature. Room temperature is generally suitable unless specified otherwise by the manufacturer.
Airtight container
Exposure to air can lead to oxidation, which may degrade the quality of the extract over time. Keep fucoidan in an airtight container to minimize its contact with oxygen. This helps maintain its potency. If the fucoidan was purchased in bulk and comes in a larger container, consider transferring a smaller quantity into an airtight bottle or jar for daily use while keeping the bulk supply sealed.
Keep away from light
Light degradation can affect the active compounds in fucoidan. Store it in a dark or opaque container if possible, or keep it in a drawer or cupboard away from direct sunlight. Avoid clear containers unless they are UV-protected.
Label appropriately
When storing fucoidan in a separate container, ensure that the container is labeled with the date of storage and the type of product. This helps avoid confusion when storing multiple products.
Refrigeration, if advised
If the fucoidan extract is liquid or if the manufacturer advises refrigeration for powdered fucoidan, then store it in the refrigerator. Maintain a consistent temperature in the refrigerator to avoid condensation forming on the product.
Keep away from strong odors
Avoid storing fucoidan near strong-smelling substances like cleaning supplies, spices, or certain foods. Fucoidan can easily absorb nearby odors and that will affect its smell and quality.
Watch the expiry date
Storage conditions play a significant role in the longevity of fucoidan extract. Always check the expiry date on the package and make sure to use the product before that date for optimal efficacy. If the fucoidan extract doesn’t have an expiry date, consult with the supplier for advice on how long the product will maintain its potency under proper storage conditions.
