Apigenin

Flavonoid Apigenin Is an Inhibitor of the NAD+ase CD38

Introduction

Apigenin is a natural compound known as a flavone, a class of flavonoids. It’s recognized for its promising bioactive properties, notably its potential role in promoting longevity and overall health, by virtue of its influence on cellular functions and its antioxidant, anti-inflammatory, and anti-cancer properties.

Brief Overview of Apigenin

Apigenin is found abundantly in various plant foods, such as parsley, celery, and chamomile tea. It’s a subject of increasing research interest due to its diverse biological activities and its potential benefits in preventing and managing a range of health conditions, from metabolic disorders to age-related diseases.

Role in Longevity and Health

Research on apigenin in the context of longevity focuses primarily on its ability to modulate several cellular pathways related to aging. Apigenin is studied for its potential to inhibit CD38, an enzyme that consumes NAD+, a vital coenzyme in cellular energy metabolism and repair processes. By potentially maintaining or elevating NAD+ levels, apigenin could play a role in delaying the aging process and mitigating age-related declines in cellular function. Additionally, its antioxidative and anti-inflammatory properties contribute to its role in promoting cellular health and longevity.

Sources of Apigenin

Apigenin is predominantly found in a variety of plant foods, contributing to the beneficial effects of a plant-rich diet. It is also available in supplement form, offering a concentrated source for those seeking to leverage its potential health and longevity benefits.

Common Foods

Apigenin is ubiquitously present in many fruits, vegetables, and herbs. Some of the rich dietary sources include:

• Parsley: A highly concentrated source of Apigenin.
• Celery: Provides a substantial amount of Apigenin.
• Chamomile Tea: A popular herbal tea rich in Apigenin.
• Oranges: Contains moderate levels of Apigenin.
• Oregano: A commonly used herb with considerable amounts of Apigenin.

Incorporating a variety of these foods into the diet can help ensure a steady intake of Apigenin, contributing to overall well-being and potentially supporting longevity.

Supplements

For those seeking higher, more concentrated doses of Apigenin, supplements are available, usually in capsule or powder form. However, it's crucial to approach Apigenin supplementation with caution and ideally under professional guidance, considering the optimal dosage, purity, and potential interactions with medications or other supplements have not been fully established. Users are advised to opt for high-quality, tested products to minimize the risk of contaminants and to adhere to recommended dosages to avoid potential adverse effects.

Benefits and Mechanisms of Action

Apigenin is not just a mere component of our diet; research has elucidated its diverse biological activities, depicting its significant role in promoting health and potentially extending lifespan through various mechanisms.

Antioxidant Properties

• Oxidative Stress Reduction: Apigenin has potent antioxidant properties, helping neutralize free radicals and reducing oxidative stress, a key contributor to aging and many chronic diseases.
• DNA Protection: By minimizing oxidative damage, Apigenin helps in maintaining the integrity of DNA, crucial for cellular function and longevity.

Anti-Inflammatory Effects

• Inflammation Modulation: Apigenin can modulate inflammatory pathways, reducing the production of pro-inflammatory cytokines and potentially mitigating inflammation-related conditions and aging processes.

Cellular Pathways and Longevity

• NAD+ Maintenance: Apigenin may inhibit CD38, potentially maintaining or elevating levels of NAD+, vital for cellular energy metabolism and repair processes, and associated with longevity.
• Sirtuin Activation: Through its potential impact on NAD+ levels, Apigenin might indirectly activate sirtuins, a family of proteins associated with lifespan extension and improved healthspan.

Cancer Prevention

• Cancer Cell Inhibition: Several studies have indicated that Apigenin can inhibit the growth of cancer cells and induce apoptosis, showing promise in cancer prevention and therapy.

Neuroprotective Effects

• Neurological Health: Apigenin may have neuroprotective properties, protecting brain cells from damage and potentially reducing the risk of neurodegenerative diseases.

Cardiovascular Health

• Cardiovascular Protection: The anti-inflammatory and antioxidative properties of Apigenin are beneficial for cardiovascular health, potentially reducing the risk of cardiovascular diseases.

Considerations and Future Research

While the benefits of Apigenin are promising, it is crucial to acknowledge that many studies are in the preliminary stages, predominantly in vitro or animal-based. More comprehensive human clinical trials are needed to validate these findings, determine optimal dosages, and understand the long-term impacts and potential side effects of Apigenin intake. Additionally, further exploration is required to elucidate the full spectrum of Apigenin’s mechanisms of action and its role in health and longevity.

Safety and Dosage

While Apigenin is generally recognized as safe due to its presence in common fruits and vegetables, considerations around its safety and dosage are paramount when contemplating supplemental use or concentrated intake.

General Safety

• Natural Sources: Apigenin is found in many fruits, vegetables, and herbs, and consuming it from these natural sources is generally considered safe.
• Side Effects: In supplemental or high doses, potential side effects include gastrointestinal discomfort, allergic reactions, or interactions with medications.

Recommended Dosage

• Dietary Intake: No formal recommendations exist for dietary intake, but consuming a diet rich in fruits and vegetables containing Apigenin is encouraged.
• Supplemental Dosage: There is no established recommended dosage for Apigenin supplements, and any supplemental use should be approached with caution and preferably under medical guidance.

Drug Interactions

• Medication Interaction: Apigenin may interact with certain medications, altering their efficacy and metabolism. Consultation with healthcare providers is essential before supplementing, especially for those on medication.

Pregnant and Breastfeeding Women

• Pregnancy and Lactation: Limited information is available on the safety of high Apigenin intake during pregnancy or breastfeeding; therefore, caution is advised, and any concerns should be discussed with a healthcare professional.

Research Limitations

• The majority of the safety and efficacy data on Apigenin come from in vitro and animal studies, necessitating further human studies to confirm its safety profile and establish appropriate dosages for therapeutic uses.
