There is rarely a meal I cook that doesn’t involve the use of garlic in some way. My favorite thing to cook recently is this Honey Garlic Chicken recipe from Family Food on the Table. The health benefits found in garlic can drastically change depending on the way you prepare it. Whether you eat it raw, cook it, or use aged garlic extract, you’re getting different compounds that affect your body in unique ways.
Let’s break garlic health benefits so you can make the most of this powerhouse ingredient.
Why Garlic Is Good for You
Garlic’s reputation as a health booster comes from its organosulfur compounds — especially allicin.
- Allicin only forms when garlic is crushed, chopped, or chewed which activates the enzyme alliinase, converting alliin into allicin.
- Once formed allicin is unstable and quickly breaks down into other beneficial compounds like diallyl disulfide and ajoene.
- Each compound has different immune and heart health benefits.
Harvard Health notes that garlic may help lower blood pressure, cholesterol, and support immune function.
Raw Garlic: The Allicin Powerhouse
Raw garlic is your best bet for getting the most allicin — but it’s intense.
- Crush or mince garlic and let it sit for 10 minutes before eating.
- This waiting period maximizes allicin formation.
- Mix minced raw garlic into honey, lemon juice, or olive oil for a less harsh taste.
- Great for short-term immune boosts (like when you feel a cold coming on).
Pro tip: The “10-minute rule” is key — don’t rush it, or you’ll miss the allicin benefits.
Cooked Garlic: Gentle and Digestible
Cooking reduces allicin but creates other beneficial compounds that support health in different ways.
- Lightly sautéed garlic preserves more nutrients while making it easier to digest.
- Roasting garlic makes it sweet and mild, encouraging you to eat more of it.
- Slow cooking in soups and stews distributes garlic’s benefits throughout the dish.
Cooked garlic is perfect for daily, long-term immune support without the intensity (or garlic breath) of raw cloves.
Aged Garlic: The Research Favorite
Aged garlic — especially black garlic or garlic supplements — is loaded with stable, easy-to-absorb compounds.
- Black garlic is made by fermenting garlic at low heat, creating a sweet, molasses-like flavor.
- It’s rich in S-allylcysteine, which is well-studied for immune and cardiovascular benefits.
- Aged garlic extract (found in supplements) may help reduce cold severity and boost overall immunity.
See this NIH review for evidence on aged garlic’s role in reducing cold and flu symptoms.
Garlic Breath & Social Survival
Worried about smelling like garlic all day?
- Eat parsley, mint, or fennel seeds afterward.
- Dairy (milk, yogurt) binds to odor-causing sulfur compounds.
- Use cooked or aged garlic when you have a busy social day — it’s far less pungent.
Quick Garlic Prep Tips
- ✅ Always chop or crush garlic — swallowing whole cloves won’t trigger allicin formation.
- ⏳ Let chopped garlic sit 10–15 minutes before cooking or eating.
- 🧄 Store whole bulbs in a cool, dry place. Avoid refrigeration unless pre-chopped.
- 🆕 Buy fresh garlic regularly — sprouted or soft garlic loses potency.
Final Thoughts
There’s no single “best” way to use garlic — it depends on your health goals and taste preferences.
- Raw garlic → Best for quick immune boosts.
- Cooked garlic → Perfect for daily, sustainable use.
- Aged garlic → Mild, convenient, and research-backed.
The most powerful approach? Mix it up. Use raw garlic occasionally, cook with it daily, and try black garlic or aged garlic extract for an extra layer of health support.
