What is Black Garlic Extract Powder?
Maybe you are know something about it or you have hear about it before. And black garlic extract powder is derived from fermented black garlic. And where we could get the black garlic ? here i would give an answer.
It is a products from fresh garlic undergoing a 60~90days controlled fermentation process under high humidity and temperature . This process transforms garlic’s pungent compounds (e.g., allicin) into milder, sweet-tasting derivatives like S-allyl cysteine (SAC).
while boosting antioxidant content. The extract is typically concentrated into a brown powder via water or alcohol extraction, retaining key bioactive components such as polyphenols, flavonoids, and organosulfur compounds.

Health Benefits of Black Garlic Extract
Antioxidant & Anti-inflammatory:
The black garlic it contain 5 to 10 more antioxidants than raw garlic,and it could neutralizing free radicals , and reduce the oxidative stress, besides them ,it also could lower the risk of chronic diseases. For example cancer, cardiovascular disease and so on.
Cardiovascular Support: Clinical studies show daily intake (20g) can reduce total cholesterol by 10–15% and LDL cholesterol by 8–12%, while improving blood vessel elasticity.
Blood Sugar Regulation: Enhances insulin sensitivity and inhibits enzymes (e.g., G-6-Pase) that raise blood glucose, aiding diabetes management.
Immune Boost: Rich in vitamins B6 and C, it strengthens immune response and reduces inflammation.
Digestive Health: Acts as a prebiotic, promoting beneficial gut bacteria and easing constipation.

What are the side effects of black garlic?
Digestive Issues: High sulfur content may cause bloating, diarrhea, or heartburn if consumed excessively (>20g/day).
Blood Thinning: Organosulfur compounds may interact with anticoagulants (e.g., warfarin), increasing bleeding risk.
Allergic Reactions: Rare cases of skin rashes or headaches have been reported. Blood Sugar Fluctuations: Diabetics should monitor levels closely due to its hypoglycemic effects.

Is black garlic good for the kidneys?
Black garlic is generally safe for kidneys and may offer benefits:
Antioxidant Protection: Reduces oxidative stress in kidney cells, potentially slowing progression of conditions like chronic kidney disease (CKD). Blood Pressure Control: Lowers hypertension, a major risk factor for kidney damage.
Anti-inflammatory Effects: Mitigates inflammation linked to kidney dysfunction. However, those with advanced CKD or on dialysis should consult a doctor before use, as high potassium content (930mg/100g) may require dietary restrictions.
