18.6 milligrams (mg) of vitamin C, or 21% of the Daily value (DV)
9.6 micrograms (mcg) of folate, or 2% of the DV
49.4 mg of potassium, or 1% of the DV
0.038 mg of iron, or < 1% of the DV
0.01 mg of vitamin B-1, or 1% of the DV
0.01 mg of vitamin B-2, or 1% of the DV
0.06 mg of vitamin B-5, or 1% of the DV

Citrus fruits like lemons contain vitamin C, a primary antioxidant that helps protect cells from damaging free radicals.
On top of that, vitamin C also plays a role in helping your body synthesize collagen, absorb iron, and produce hormones.
Additionally, not consuming enough vitamin C may cause symptoms, like:
increased susceptibility to infections

May support weight loss
Drinking lemon water may help you increase your water intake, which is often recommendedTrusted Source as a weight-loss strategy. However, there’s limited evidence to justify this.
In a 2018 studyTrusted Source, researchers found that participants who were instructed to drink water before eating a test meal ate less food than when they were instructed to eat the test meal without “pre-loading” with water.
When participants drank water before eating a test meal, they did not feel significantly less satiated, despite eating less food.
The study’s authors concluded that pre-meal water consumption may be an effective weight-loss strategy, although the mechanism of action is unknown.
Easy alternative to sugary drinks

In a 2021 study, participants drank 300 mL of either water or lemon water prior to eating meals for 4 weeks. The researchers collected stool samples before and after the test period and participants’ intestinal microbiota were analyzed.
The study’s authors found that pre-meal intake of lemon water appeared to promote digestion and peristalsis, or the wave-like contractionsTrusted Source that help move food through the digestive tract. However, more large-scale studies are needed to fully understand the effects of lemon water on digestion.
