Product Details

What is Kaempferol?

Kaempferol is a flavonol—a subclass of polyphenolic flavonoids found in many plants, fruits, and vegetables. Individuals consume approximately 20-50mg of flavonols per day, with an average of 23mg/day. Kaempferol accounts for about 17% of the total flavonol intake. Cruciferous vegetables like broccoli are rich kaempferol sources, and it’s one of the primary bioactive flavonoids found in ginkgo biloba. It shares a structural similarity with quercetin, as removing one of the hydroxy groups from quercetin creates kaempferol. It has antioxidant, anti-inflammatory, and neuroprotective properties.

What are Flavonoids?

Approximately 60% of all polyphenols are flavonoids. The term flavonoid comes from flavus, the Latin word for yellow, and reflects its naturally occurring distinctive color. It is critical for producing many plant pigments. Flavanols are a subclass of flavonoids also known as anthoxanthins. Like all flavonols, kaempferol is a product of the phenylpropanoid pathway unique to plants. To synthesize kaempferol, plants use the Shikimate pathway to form the aromatic amino acids phenylalanine. They then use the phenylpropanoid pathway to convert the phenylalanine into kaempferol.

What are Flavonoid Foods?

Many foods are rich in flavonoids. These include blueberries, bananas, citrus fruits, dark chocolate with at least 70% cocoa, red wine, and various teas. Numerous foods contain kaempferol specifically, but the best sources with the highest kaempferol levels include capers, saffron, arugula, kale, mustard greens, ginger, and beans. Kaempferol is a component of several plants, too. These include aloe vera, St. John’s Wort, soybeans, rosemary, and elderberry. PureBulk sources kaempferol extract from the fruit of the Styphnolobium japonicum tree.

Potential Kaempferol Flavonoid Benefits

Kaempferol as an Antioxidant and Anti-Inflammatory

Flavonoid Supplements

PureBulk carriers several other flavonoid supplements, including:

Kaempferol, like most flavonoids, has antioxidant properties. It can suppress the proliferation of malignant cells by inducing apoptosis (death). Kaempferol achieves this by increasing the internal oxidative stress within the malignant cell, a process known as redox perturbation. Kaempferol also protects cells from inflammation by blocking proinflammatory cytokines. Inflammation is a normal part of the immune response, but chronic inflammation caused by these cytokines increases the risk of carcinogenesis, promotes DNA oxidative damage, and contributes to the formation or worsening of many health conditions. Kaempferol also has antiviral properties that inhibit virus replication in animal studies. Researchers have also noted kaempferol exerts neuroprotective effects and may support a healthy central nervous system (CNS).

Kaempferol and Weight Loss

Kaempferol may improve weight loss efforts. Studies show kaempferol reduces fat absorption, visceral fat accumulation, weight gain, and cholesterol content. It inhibits enzymes that synthesize fatty acids from glucose for fat storage. Kaempferol also encourages the body to form bone tissue rather than fat storage cells (adipocytes).

Potential Kaempferol Side Effects

Most individuals can take kaempferol extract without experiencing adverse effects, as it is a naturally occurring compound in many foods. Kaempferol may reduce iron absorption, as flavonoids can chelate redox-active metal ions. However, this effect is much less notable in kaempferol than in other flavonoid compounds.
