Black garlic is a special variety of garlic that is aged for several weeks at high temperatures and high humidity levels. Black garlic extract is a dietary supplement made from black garlic. The garlic cloves undergo a transition because of this ageing process; they go from being white or off-white to a deep brown and then completely black. As the garlic ages, amino acids and reducing sugars undergo chemical changes that lead to the Maillard reaction, which is principally responsible for the colour shift.

The flavour and texture of black garlic are distinct from those of raw garlic, in addition to differences in colour. Compared to the strong, harsh flavour of raw garlic, it has a softer taste. Black garlic is unique in culinary and dietary uses because of its more delicate, sticky, and syrupy consistency, which is a result of the ageing process.

In addition, black garlic is highly regarded for its possible health advantages, which are thought to outweigh those of raw garlic. These benefits related to garlic’s ageing and transformation have drawn a lot of interest from complementary medicine and dietary supplement sectors.


Here are some of the alleged Black Garlic benefits:

  • Rich in Antioxidants: When compared to raw garlic, the ageing process that produces black garlic greatly increases its antioxidant content. Allicin, the substance that gives raw garlic its strong smell when crushed, changes into antioxidants like flavonoids and alkaloids as it ages. Antioxidants are essential for shielding cells against oxidative damage, which is linked to a number of illnesses. Because black garlic has a higher content of antioxidants, it offers better protection for cells. According to a 2014 study, black garlic’s overall antioxidant activity rises noticeably with age, peaking at about 21 days.
  • Blood Sugar regulation: Blood sugar regulation has been demonstrated to be aided by black garlic. In experiments conducted on animals, the ingestion of black garlic extract resulted in improvements to metabolism, such as decreased inflammation, cholesterol, and improved regulation of hunger. Aged black garlic showed stronger antioxidant activity than fresh garlic in an earlier study conducted in diabetic rats, indicating that it may be useful in reducing problems connected to diabetes. A different study using high-fat mice showed that eating black garlic decreased insulin and blood glucose levels. Even though these results are encouraging, more investigation is required to fully comprehend how black garlic affects human blood sugar management.

  • Cardiovascular health: Black garlic may lower heart disease risk factors, according to research on animals. It has been demonstrated to raise HDL (good) cholesterol while lowering triglycerides, total cholesterol, and LDL (bad) cholesterol. Furthermore, studies on black garlic extract have shown that it can shield the heart from harm caused by ischemia, or decreased blood flow. Consuming black garlic extract raised antioxidant levels and enhanced heart health indicators in research involving participants with coronary heart disease. However, inconsistent results from human studies on black garlic’s effects on heart disease risk factors have made further research necessary to confirm these potential benefits in human populations.

Although the initial results on black garlic’s health benefits are encouraging, it’s crucial to remember that additional thorough human research are needed to completely comprehend and validate these benefits. Furthermore, each person’s reaction may differ, so consulting a healthcare provider before adding black garlic extract to a diet is advised—especially for individuals with health issues or concerns.


There are several possible processes via which black garlic interacts with the human body after ingestion, all of which may contribute to its potential health advantages. The most notable of them is its increased antioxidant content, which is a consequence of the Maillard reaction that occurs during the ageing process.

Through this process, antioxidant chemicals including alkaloids and flavonoids are created from allicin, the molecule that gives raw garlic its pungent smell. Because they neutralise free radicals, which are known to harm cells and play a role in ageing and a number of diseases, antioxidants are essential in the body’s defence against oxidative stress. Black garlic’s higher antioxidant content provides better cellular defence, which may lessen the likelihood of oxidative damage-related disorders.

Additionally, black garlic appears to have potential in controlling blood sugar levels. Even though a lot of the research is conducted on animals, the results point to the potential benefits of black garlic extract for metabolic markers. It has shown promise in reducing inflammation, decreasing cholesterol, and affecting the control of hunger. Its antioxidant qualities might potentially help to avoid diabetes-related problems. Research suggests that black garlic, particularly in animal models, may lower insulin and blood glucose levels. However, more studies using human participants are required to fully comprehend the scope of these blood sugar-regulating abilities.


The appropriate dosage of black garlic extract to take for each person can differ depending on a number of variables, such as their general health, particular medical issues, and personal reactions. As of right now, there isn’t a single, widely accepted daily dosage for black garlic extract. While the amounts found in studies can provide some information, it’s crucial to proceed with caution when thinking about higher doses.

Various dosages have been used in studies and research on black garlic extract; the best dose may vary depending on the health condition. Studies have investigated the benefits of taking 600–1,500 mg of black garlic extract daily for specific medical conditions. It’s important to note that each person may react differently, and there is now insufficient evidence to determine whether using more or longer amounts of black garlic extract is safe. Before beginning a black garlic extract regimen, like with any dietary supplement, it is best to speak with a healthcare provider, especially if you have any underlying medical issues, take medication, or have specific health concerns.
