Lemon Water Benefits

Let’s talk about the several health benefits that lemon water can provide to your body, backed by science.

1. It is a rich source of vitamin C

Lemon is a citrus fruit, and as citrus fruits go, it is rich in vitamin C – the primary antioxidant that helps protect our cells from the damaging effect of free radicals and powers our immune system (1,2)

More than that, vitamin C also helps our body absorb iron, synthesize collagen and produce hormones (3).

Vitamin C is an important ally in preventing infections, dry skin, fatigue, insomnia, or the loosening of teeth.

So, by drinking water lemon every day, you get most of the benefits of lemon. Squeezing a lemon into a glass of water will get you approximately 20% of the DV of vitamin C.

Summary:Lemon is a citrus fruit rich in vitamin C. Vitamin C plays several roles including being an antioxidant, aiding our immune system, and assisting with absorbing nutrients like iron

2. It helps with your digestion

You’ve probably heard already that drinking lemon water can help relieve constipation, especially if you use lukewarm water to make it and drink it every morning. But is it true? Let’s see what the studies say!

As part of a 2021 study, participants drank 300 mL of lemon water before every meal for 4 weeks. The researchers examined stool samples from the participants to analyze how their intestinal microbiota evolved during the test period. The results were promising, showing that a pre-meal intake of lemon water can boost peristalsis and help move food through the digestive tract more efficiently (4).

Moreover, lemons are rich in pectin – a soluble form of fiber that can have multiple benefits on your health, improving your gut health and slowing the digestion of sugars and other starches (5).


While the results so far are promising, more studies are needed to say for sure that lemon water aids digestion.

What you can do is drink one glass of lemon water every morning for 3-4 weeks and analyze how you feel. If you feel considerable benefits, keep doing it.

Summary:Some studies have suggested that drinking lemon water may help improve digestion, and some show that consuming lemon water before a meal may help boost peristalsis.

Do a little experiment. Rub a lemon in your hands, and you will see how it neutralizes any odor (6). Lemons do have this fantastic property of removing foul smells. (7)

You can apply the same principle to keep a fresh breath at all times. So, make sure you drink a glass of lemon water before you go on your next romantic date. It might increase your chances of success.

Now, seriously, you can try having a glass of lemon water after a meal rich in onions, garlic or fish. It will help you feel better.

But is there a scientific fact behind this? Well, lemons can stimulate the production of saliva, preventing a dry mouth (8). What is more, the citric acid in the fruit can help break down the bacteria that induce bad breath (9).

4. It helps maintain the mineral balance in the body

Although lemons are acidic, lemon water is an alkaline solution that you can drink to balance the effects of the acid-forming foods you eat (10).

When metabolized, lemon juice becomes alkaline, and it helps rehydrate the body.

Lemon water is a highly hydrating drink you can use to replenish your body, especially if you spend lots of time in the gym and lose essential minerals through perspiration.

It is believed that lemon water is a more efficient hydration drink than plain water. Plus, you also get the benefit of rebalancing the minerals in the body.

5. Rich in antioxidants and flavonoids

Lemons are rich in vitamin C, one of the mightiest antioxidants out there (11). But that’s not all that lemons can do. Besides vitamin C, they also contain flavonoids – plant compounds with potent anti-inflammatory and antioxidant effects (12).

Antioxidants and free radicals should keep a fair balance in the body. Too many free radicals can lead to cell damage which can cause a series of serious conditions, such as cardiovascular disease, diabetes, obesity and even cancer.

Various studies have found a correlation between increased inflammation markers, oxidative stress caused by free radicals and conditions such as arthritis, diabetes, autoimmune diseases or even cancer (13).

In a scientific review from 2019, the antioxidants and flavonoids from citrus fruits were found to improve heart health and other conditions such as insulin sensitivity, glucose tolerance or fat metabolism (14).

Did You Know?:In addition to antioxidants like vitamin C, lemons are rich in flavonoids. Flavonoids can help to improve inflammation and reduce the amounts of free radicals in the body.

6. May prevent kidney stones

Kidney stones are an accumulation of minerals that build up in the kidneys. One of the most common forms of treatment is made of a compound called citrate. This compound can stop calcium from binding with other minerals and form kidney stones.

Preliminary research suggests that lemon water can help treat kidney stones. A study review from 2015 has shown that citrus fruits can increase the citrate levels in the urine and may help prevent kidney stones.

In case you are already struggling with this condition, water and lemon water can help break up and flush out small kidney stones. But don’t stop there.

You know you need to keep your body hydrated at all times to prevent any other complications further down the road, including kidney stones. If you get rid of them once, it doesn’t mean they won’t come back. If you drink enough water and lemon water daily, you will also flush out all the toxic waste in the body, keeping it healthy and clean.

Due to the vitamin C content in lemons, drinking lemon water may also boost collagen production (15).

Collagen is the main structural protein that helps strengthen the skin and prevent any damage from the effect of free radicals. It may make your skin more elastic and shinier, so you can glow with joy and confidence.

A large-scale study review concluded that vitamin C deficiency could lead to a higher risk of death from cardiovascular disease (21). The actual studies are not enough to prove that the widespread use of vitamin C could drastically reduce cardiovascular risk, but they offer an optimistic assumption.
