Garlic Water Benefits: What It Does and Doesn't Do

Garlic water supports hydration, while possible cholesterol and blood pressure benefits are based on studies of garlic supplements, not garlic water. This guide separates what is known about garlic water from what remains unproven.

What are the 3 possible benefits of garlic water?

For another way to plan an infusion, try the ai infused water generator.

The three benefits to consider are hydration, possible cholesterol effects and possible blood pressure effects. Hydration comes from the water itself and is well established. The other two are promising areas of garlic research, but there is not enough evidence to say that a homemade infusion produces the same effects as the supplements studied.

Crushing garlic forms sulfur compounds, including allicin, that researchers have investigated for health effects. The amount that ends up in a glass of garlic water is not established and will vary with how it is prepared.

Does garlic water help you stay hydrated?

1. Hydration

How it may work: The water in garlic water contributes to your fluid intake. Your body needs water for functions including temperature regulation, circulation and the removal of waste through urine.

Garlic does not make water uniquely hydrating. The practical advantage is that some people may find its savory flavor makes water more appealing, although others may prefer plain water.

How to use it: Have a glass with a meal or when you would normally drink water. It can be one option in your usual fluid routine; there is no need to force yourself to drink it or consume large amounts.

Strength of evidence: Water’s role in hydration is well established. The effect comes from drinking water, not from a demonstrated special property of garlic water. If a clinician has advised you to limit fluids, count garlic water toward that limit.

Can garlic water improve cholesterol?

2. Possible cholesterol support

How it may work: Garlic contains sulfur compounds that have been studied for potential effects on blood lipids. The mechanisms are still being investigated, and the compounds and quantities in a supplement are not necessarily the same as those in garlic water.

How to use it: If you enjoy garlic water, drink it as a beverage alongside your usual food choices. Do not use a homemade infusion as a substitute for a cholesterol treatment or assume it will change a blood test result.

Strength of evidence: A 2024 review of supplement research reported that garlic supplements were among the products associated with lower cholesterol in studies of people with high cholesterol. Its findings concern supplements, not garlic steeped in water.

A 2021 randomized trial also found improvements in several blood lipid measures in people with metabolic syndrome who took garlic powder. That result supports further research, but it does not establish an effective recipe or dose for garlic water. Your response to food or drink cannot be predicted from a supplement trial.

Can garlic water lower blood pressure?

3. Possible blood pressure support

How it may work: Researchers have investigated whether garlic preparations affect blood vessels and blood pressure. Those effects depend on the preparation studied, and the mechanism and effect of a homemade infusion are uncertain.

How to use it: Treat garlic water as a drink, not a way to manage high blood pressure. If you monitor your blood pressure or take medication for it, continue to follow your clinician’s plan rather than relying on how you feel after drinking garlic water.

Strength of evidence: The 2021 randomized trial of garlic powder found lower blood pressure in the supplement group than in the placebo group among participants with metabolic syndrome. A small 2022 randomized trial of aged garlic extract also found a short-term improvement in a measure of small-vessel function in older adults at cardiovascular risk.

These trials used different garlic preparations, and neither tested garlic water. An earlier review of garlic’s health effects noted that blood pressure reductions had not been consistent across studies. There is no established amount of garlic water to drink for a blood pressure effect.

What does garlic water not do?

Garlic water does not detox the body or cleanse the blood. The liver and kidneys do most of the body’s detoxification, while the lungs and gut help eliminate waste; sweat removes only trace amounts. Drinking water supports normal hydration, but adding garlic does not turn it into a detox treatment.

Garlic water has not been shown to burn fat, cure an infection or replace treatment for high cholesterol or high blood pressure. Changes observed in a supplement trial should not be assumed to occur when a clove is steeped in water.

Nor is stronger flavor proof of a greater health effect. A more concentrated drink may be less comfortable to consume without providing a measurable benefit.

How should you make and drink garlic water?

A mild infusion is a practical starting point. This is a flavor recipe, not a medically tested dose.

Ingredients

• 1 liter water (about 4¼ US cups)
• 1 teaspoon minced garlic (about 3 g)

Method

1. Wash your hands and use a clean pitcher, knife and cutting board.
2. Peel the garlic and mince enough to measure 1 teaspoon.
3. Add the garlic to the water in the pitcher and cover it.
4. Refrigerate for 2–4 hours to let the flavor develop.
5. Strain out the garlic if preferred, then pour a serving.

Keep the garlic water refrigerated and drink it within 24 hours for the best flavor. Discard it after 2–3 days, or sooner if it becomes cloudy, slimy or sour-smelling. Do not leave it at room temperature for more than a few hours.

Start with a small serving to see whether you like the taste and tolerate it comfortably. There is no proven best time of day to drink garlic water and no established schedule for gaining the proposed cardiovascular benefits.

Who should be careful?

Garlic can cause digestive discomfort or bad breath. If it upsets your stomach, stop drinking it; seek medical advice if symptoms are severe or persist. Get urgent medical help for trouble breathing or swelling of the lips or throat after consuming it.

Garlic has antiplatelet activity, and concentrated garlic products may increase bleeding risk. If you take an anticoagulant or antiplatelet medication, have a bleeding disorder, or have a procedure or surgery planned, ask your clinician about regular garlic water use and any garlic supplements. Do not stop prescribed medication on your own.

If you are pregnant, preparing garlic water for a child, or considering it alongside blood pressure medication, ask a clinician about regular use. Food amounts of garlic are different from concentrated supplements, and the strength of homemade garlic water is not standardized.

Sources

The evidence for cholesterol and blood pressure comes from garlic preparations rather than garlic water. The studies linked above include a review of cholesterol supplements, a randomized trial of garlic powder, a small randomized trial of aged garlic extract, and a review of garlic’s health effects. They are useful for understanding the research, but they do not establish benefits or a treatment dose for this recipe.
