Flavonoids are essential phytochemical constituents with numerous beneficial properties for health improvement. Some of the most common natural flavonoids found in dietary supplements are myricetin, quercetin, luteolin, and apigenin.
Among these flavonoids, apigenin has gained increased attention due to its relatively low intrinsic toxicity, complemented by its beneficial bioactivities.
From reducing anxiety to improving sleep, enhancing testosterone synthesis to preventing chronic diseases, apigenin has much to offer. In this article, we'll review the top eight benefits of apigenin based on scientific evidence.
What is apigenin?
Apigenin is a naturally occurring flavonoid, most notably found in chamomile and many vegetables, fruits, and medicinal plants. It is known for its numerous health benefits, including anti-inflammatory, antioxidant, and anticancer properties.
Studies have shown that apigenin may also have antianxiety, antidepressant, and sleep-promoting effects, as well as supporting immune function and improving cognitive function. Because of its potential therapeutic benefits, apigenin is an active area of research in natural medicine and functional medicine.
Pure Apigenin is a single ingredient formulation, sourced to purity levels exceeding 98.7%.
An overview of apigenin benefits
Apigenin is one of the most renowned phenolic compounds with many beneficial properties, and it is available in nutraceutical formulations and dietary supplements.
Here are some of the most notable benefits of apigenin:
1. Supports heart health
Apigenin has been demonstrated to alleviate cardiovascular conditions by preserving the vascular lining in the aorta. It also induced the direct reduction of blood pressure by inhibiting of the activity of the angiotensin-converting enzyme, preventing blood vessel constriction.
According to studies, the habitual intake of flavonoids and a diet rich in apigenin leads to decreased incidence of hypertension, resulting in the reduction of cardiovascular diseases. Additionally, apigenin-rich olive extracts can improve endothelial dysfunction, suggesting a cardio protective effect of apigenin.
2. Boosts brain function
Several natural bioactive compounds have been implicated in improving learning and memory. Various clinical trials have shown the therapeutic potential of apigenin as a neuroprotective agent.
Apigenin is a promising candidate for treating and preventing different neurological disorders, such as Alzheimer’s disease and Parkinson’s disease due to its antioxidant and anti-inflammatory properties, as well as its ability to reduce oxidative stress and improve cognitive function.
3. Relieves depression
Apigenin also possesses antidepressant and antianxiety effects by selectively inhibiting the brain's monoamine oxidases (MAOs), enzymes that break down neurotransmitters such as serotonin, dopamine, and norepinephrine. Increased brain MAO activity is associated with several psychiatric/neurological disorders, such as depression and anxiety. By inhibiting MAOs, apigenin may exert an anti-depression effect.
A clinical trial has shown administering apigenin-rich chamomile extracts to individuals with depression and anxiety resulted in a significantly higher reduction in total Hamilton Depression Rating Scale (HDRS) score, which assesses the severity of depression symptoms in individuals.
4. Aids sleep
Insomnia is a troublesome sleep disorder that can negatively impact one’s overall health and well-being. Apigenin has a well-documented sedative effect, and may induce a positive and restorative activity against insomnia. It may also enhance GABA activity, a neurotransmitter that has calming effects in the brain, and promote the release of melatonin, a hormone that regulates the sleep-wake cycle.
In one clinical trial involving the elderly, apigenin successfully exhibited sleep-potentiating effects. Upon administration of apigenin-rich chamomile extract, the participants' sleep quality significantly improved.
5. May increase testosterone
Testosterone is a hormone primarily generated in males’ testes. Low testosterone can affect sleep, mood, bone mass, and the size of testicles. It can also reduce sex drive and may lead to erectile dysfunction.
Apigenin can potentially improve testosterone production and may even delay lowering testosterone levels due to aging. Experimental studies have previously demonstrated increased testosterone production from apigenin treatment. Further, the apigenin-induced increase in testosterone levels can also help promote muscle mass gain.
6. Prevents cancer
Apigenin has striking effects against cancerous cells while remaining non-toxic to normal cells. Apigenin is a potentially effective therapy against different types of cancer.
One study showed apigenin could effectively suppress prostate cancer progression by targeting a carcinogenesis-required signaling pathway. Regular apigenin intake is also implicated in having protective roles in the context of lung and ovarian cancer. Experts suggest apigenin can be used as a chemotherapeutic agent in combination with immunotherapy.
7. Increases insulin secretion
Apigenin also possesses anti-diabetic properties due to its capacity to lower blood glucose levels and increase insulin secretion.
In addition, apigenin can inhibit α-glucosidase activity. The α-glucosidase enzyme catalyzes the conversion of the big carbohydrate molecules from food into small glucose units, raising the blood sugar level. Since apigenin can inhibit it, it can help delay the digestion of carbohydrates, preventing high blood sugar levels.
8. Strengthens bones
Apigenin may also be useful in treating and preventing several bone loss disorders, such as osteoarthritis and osteoporosis, through its ability to accelerate bone fracture healing, new bone formation, and increase bone mineral density.
In patients with knee osteoarthritis, molecular evidence indicates apigenin can inhibit the molecules that degrade the components of the cartilage extracellular matrix, conferring a protective effect.
What foods contain apigenin?
Apigenin is most commonly associated with chamomile, but is also ubiquitous and abundant in other food products. Apigenin is present in at least 506 food components, where fresh parsley can contain the highest average amount.
Other food products that are rich in apigenin include:
| Parsley | This herb is one of the richest sources of apigenin and can provide up to 215 mg per 100 grams. |

Taking apigenin in supplements
The recommended dietary intake value for apigenin is not established. According to reports, apigenin intake from a regular daily diet doesn't reach the therapeutic doses used in clinical trials.
A typical formulation for apigenin supplements is prepared in 50 mg capsules with standardized apigenin content of about 20%. Intake of one to two capsules is recommended per day, one before sleep and one with breakfast, and may be adjusted based on the advice of a medical practitioner.
Apigenin, mainly in the form of standardized chamomile extract, may also be combined with other dietary supplements, such as NMN, quercetin, magnesium, or threanine, for better results. For example, the recently gone-viral Huberman’s sleep cocktail is a concoction of magnesium-threonate, apigenin, and theanine taken 30–60 minutes before bedtime.
To choose an apigenin supplement, consider these factors in picking the right product for you: quality, dosage, form, other ingredients, reviews, and price.

Beneficial dosages extend to at least 500mg/day where the two important benefits have been shown to be its anti inflammatory properties that greatly reduce prostate BPH and most importantly, reducing the enzyme CD38 that leaks from senescent cells. CD38 devours NAD+ a vital molecule required for over 200 biochemical reactions. Lack of NAD+ ( which is almost universal i people over 50) is profoundly linked to almost every disease of aging including possibly cancer. I suggest that you do your own homework on this. I promise that you will be impressed.
Apigenin must be refrigerated because heat destroys it. Thus, hot brewed camomile tea is worthless. Apigenin has low bioavailability because it is insoluble in water and must be taken with a source of fat. Best to find a liposomal version for maximum effectiveness.
