Black Garlic Bulb Extract

Also known as: Black garlic, Fermented garlic, Aged garlic extract, Black Garlic Bulb Extract

Overview

Black garlic is a fermented variant of garlic produced through a controlled aging process that utilizes high temperatures and humidity. This unique fermentation process significantly enhances its chemical profile, notably increasing concentrations of antioxidants, such as polyphenols and flavonoids, compared to fresh garlic. Research has highlighted its therapeutic potential, particularly in improving cardiovascular health, aiding in blood glucose regulation, and enhancing antioxidant activity. Black garlic is commonly available in forms such as capsules and extracts. The fermentation not only boosts the levels of bioactive compounds but also improves their bioavailability, leading to better absorption and efficacy. Due to these properties, black garlic has become a popular choice among health practitioners and consumers seeking to enhance their wellness.

Benefits

Black garlic has been shown to offer several evidence-backed health benefits: (1) **Blood Glucose and Lipid Control**: A systematic review indicates that black garlic can significantly reduce fasting blood glucose levels by -7.01 mg/dL and HbA1c levels by -0.66%, making it beneficial for individuals with type 2 diabetes. (2) **Blood Pressure Regulation**: Research demonstrates that black garlic, particularly when combined with pomegranate extracts, can improve both systolic and diastolic blood pressures, indicating potential cardiovascular benefits. (3) **Antioxidant and Anti-inflammatory Properties**: The high levels of antioxidants in black garlic contribute to reduced inflammation and oxidative stress, benefiting individuals with hyperlipidemia and diabetes by improving blood lipid profiles.

How it works

The bioactive compounds in black garlic, primarily allicin and its derivatives, modulate critical biological processes. They inhibit the enzyme HMG-CoA reductase, which is essential for cholesterol synthesis, consequently reducing cholesterol levels. Additionally, these compounds enhance insulin sensitivity and glucose uptake by promoting cellular activity. The fermentation process enhances the bioavailability and absorption efficiency of these beneficial compounds, facilitating effective management of glucose and lipid profiles.

Side effects

Black garlic is generally recognized as safe for most individuals when consumed within recommended dosages. However, some may experience mild gastrointestinal issues, including discomfort, nausea, and bloating. Rarely, allergic reactions such as skin rashes can occur. Caution is advised for individuals on anticoagulant or diabetic medications due to potential pharmacological interactions. Contraindications include individuals with severe gastrointestinal conditions, pregnant or breastfeeding women, and those preparing for surgery. It is essential to consult with healthcare professionals to ensure safe intake and to manage any related risks, particularly for patients with diabetes or hypertension.

Dosage

While a definitive minimum effective dose for black garlic extract has not been established, research suggests typical dosages ranging from 140 mg to 1,200 mg daily. An optimal effective dosage is often noted between 600 mg and 1,200 mg, best taken in divided doses throughout the day. Although explicit upper limits are not thoroughly defined, taking more than 1,200 mg daily lacks extensive studies. The extract can be ingested at any time, though it is recommended to take it with meals to reduce gastrointestinal discomfort. Utilizing standardized forms like capsules or tablets can ensure consistent intake of active compounds, while maintaining hydration and a balanced diet can enhance its beneficial effects.
