How long does it take for garlic to work in your body?

its a very important problem for who want to buy and eat black garlic,in common if you eat black garlic after two hours will be a reaction, the most common is the increase in gas, black garlic begins to regulate the intestines

Immediate Effects (Minutes to Hours):
- Digestion: Garlic starts being digested in your stomach within minutes.
- Allicin Formation: When garlic is crushed or chopped, the enzyme alliinase converts alliin into allicin (the main bioactive compound) within seconds to minutes.
- Absorption into Bloodstream: Allicin and its breakdown products (like allicin-derived organosulfur compounds) are absorbed relatively quickly. Significant levels can be detected in the blood within 1-2 hours after eating raw garlic.
- Antibacterial Effects (Local): In the mouth and gut, some antibacterial effects might begin almost immediately upon contact.
Short-Term Effects (Hours to Days):
- Circulatory Effects: Garlic is known to have mild vasodilatory effects (relaxing blood vessels) and may slightly lower blood pressure temporarily. These effects might be noticeable within a few hours.
- Immune System Stimulation: Garlic components can interact with immune cells quickly. While you won’t feel your immune system working, the biochemical processes start within hours. For fighting a common cold, some people report benefits within 1-2 days of starting high intake (like raw garlic or aged extract supplements), but evidence is mixed and individual.
- Antioxidant Activity: The antioxidant compounds in garlic enter your bloodstream within hours and start neutralizing free radicals.
Long-Term/Cumulative Effects (Weeks to Months):
- Cardiovascular Benefits (Cholesterol, Blood Pressure): This is where garlic (especially aged garlic extract or consistent high intake of raw garlic) is most studied. Significant reductions in LDL (“bad”) cholesterol (around 10-15%) and modest reductions in blood pressure generally require consistent daily intake for at least 4 to 12 weeks.
- Anti-inflammatory Effects: Chronic inflammation reduction builds up over time with regular consumption, likely taking weeks to months.
- Long-Term Disease Risk Reduction: Potential benefits for reducing the risk of certain cancers, cardiovascular disease, or cognitive decline are associated with regular, long-term consumption (months to years), not a single dose.

Key Factors Influencing Timing:

Form & Preparation: Raw, crushed garlic provides the most allicin. Cooking significantly reduces allicin (but creates other beneficial compounds). Aged garlic extract (common in supplements) provides stable, bioavailable compounds (like S-allyl cysteine) absorbed efficiently but may take longer for cumulative effects than raw allicin.
Dosage: Higher doses (like several raw cloves daily or standardized supplements) will generally lead to faster and more pronounced effects than a small amount.
Frequency: Consistent daily intake is crucial for the long-term benefits.
Individual Factors: Your metabolism, gut health, overall diet, genetics, and the specific health condition you’re targeting all influence how quickly and effectively you respond.

In Summary:

Compounds enter your blood: Within 1-2 hours (especially from raw garlic).
Immediate physiological changes (like vasodilation): Can start within hours.
Potential immune support/acute symptom relief: Might be noticeable within 1-3 days for some people (e.g., colds).
Significant cardiovascular benefits (cholesterol/BP): Require consistent daily intake for 1-3 months.
Long-term preventive effects: Require regular consumption over months to years.
