Lemon is a citrus fruit and a vital vitamin C source. It is known for its refreshing flavor and scent. Due to the benefits of lemon for babies, parents consider adding it as a supplementary component while preparing their drinks or foods, but some doubt whether it is safe enough to do so.

Lemon contains high quantities of bioactive compounds and is considered a healthy option in several home remedies. Including lemon in your regular diet could boost your immune system, make your skin healthy, and enhance iron absorption.

This post shares some details about the health benefits, safety, and appropriate ways to include lemon in your baby’s diet.

When Can Babies Have Lemons?

It is generally recommended to introduce citrus fruits to babies after about six months of age (1) (2). You may consider adding lemons after the age of eight months, which is when other citrus fruits, such as oranges, are included in a baby’s diet (3).

Some parents consider waiting up to the age of 12 months due to the high acidity of citrus fruits (4).  You may consult a pediatrician to know the best age to introduce lemons to your little one.

Though rare, allergy to lemons exists (5). However, according to the American Academy of Pediatrics, there is no reason to delay feeding foods considered allergens (6). These foods can be added to the baby’s diet with other non-allergenic foods. But if your baby tends to display an allergic reaction or intolerance to new foods, is allergic to other citrus fruits, or has a family history of allergies, then do not introduce lemons without consulting a doctor.

Nutritional Value Of Lemon

Lemons provide several essential nutrients, such as vitamin C, minerals, dietary fibers, and phytochemicals, such as carotenoids and phenolic acids (7) (8).

One fluid ounce (31g) of freshly squeezed, 100 percent lemon juice offers the following nutrients in comparison to the daily recommended intake for each nutrient (9) (10) (11) (12).

Name Amount RDA (7-12months)
Water 28.6g
Carbohydrate, by difference 2.14g
Fiber, total dietary 0.093g
Magnesium, Mg 1.86mg 60
Phosphorus, P 2.48mg 275 (AI)*
Potassium, K 31.9mg 700
Vitamin C, total ascorbic acid 12mg 35
Folate, total 6.2µg 80 (AI)*

*AI = Adequate intake – nutrient level considered to ensure nutritional adequacy

Possible Health Benefits Of Lemon For Babies And Toddlers

Here are some significant health benefits of lemon juice a baby could reap over time.

  1. Provides hydration: One fluid ounce of fresh lemon juice can give 28.6g of water with essential vitamins and minerals, thus having hydrating effects (13). You can give diluted lemon juice in small quantities to your baby/ toddler.
  1. Boosts immunity: Lemon juice is rich in vitamin C, citric acid, and bioactive compounds, such as eriocitrin, that are considered good for immunity (14). Besides, it possesses antimicrobial and anti-inflammatory properties that can benefit the immune system (13).
  1. Enhances digestion: When consumed in small amounts, D-limonene found in lemon juice could increase gastric motility, neutralize stomach acids, and reduce indigestion symptoms, such as nausea and gastric reflux (13). There are several home remedies where diluted lemon juice is used to boost a baby or toddler’s digestion.
  1. Increases iron absorption: Adding vitamin C-rich lemon juice to non-heme foods, like spinach and pulses, can enhance iron bioavailability (15). Babies on a solid diet need adequate iron to boost neurological development and a healthy circulatory system (16) (17).
  1. Relieves cold and flu: Research indicates that lemon has antiviral properties and could reduce mucus and phlegm. A cup of warm water with lemon juice may help alleviate cold and flu symptoms (13) (18).

Possible Side Effects Of Lemon For Babies And Toddlers

Avoid feeding undiluted lemon juice to babies and toddlers. Lemon may not have any side effects in a healthy child if taken in small quantities diluted in water, or in some recipes. Otherwise, below are some potential side effects of lemon consumption among babies and toddlers.

  1. Gastrointestinal disturbances: Lemon juice is acidic and may aggravate gastrointestinal issues, such as gastroesophageal reflux, in sensitive babies and toddlers. Therefore, feed only diluted lemon juice to babies as part of some recipe. If the baby seems uncomfortable, discontinue its use and try after some weeks.
  1. Tooth decay: Frequent and prolonged exposure to citric acid can cause enamel erosion making teeth susceptible to decay in the long run (19) (20). Rinse your toddler’s mouth with plain water every time they consume diluted lemon juice.

  1. Citrus allergy: Although rare, citrus allergy is possible. Babies with a family history of pollen and grass allergies may have a risk of developing citrus allergies (21) (22). A baby with such an allergy can display an allergic reaction on the consumption of lemon juice or on the touch of a lemon peel.

Some babies may display mild oral rash or gastric disturbances on the first consumption of lemons. These are not signs of allergy. Once the body adapts to the new food, these disturbances will be gone. However, if the baby displays signs of severe intolerance or allergy, then stop feeding lemons and consult a pediatrician.

Useful Tips To Buy And Store Lemons

Here are some tips for the proper selection and storage of lemon.

Selection tips

  1. Pick medium-sized, plump lemons with clean, smooth, firm, and shiny skin. Plump lemons are juicier.
  1. Discard lemons that look squishy and spongy and have green, black, or white molds.
  1. Do not pick lemons with wrinkled skin as they are likely to be aged and have less juice.

Storage tips

  1. As you get lemons home, clean them under cold, running water to remove soil, dust, and dirt.
