Alfalfa Leaves Side Effects

Alfalfa leaves are generally considered safe for most people when consumed in moderate amounts as part of a balanced diet. However, some individuals may experience side effects or adverse reactions, particularly when consumed in large quantities or as a supplement. Here are some potential side effects and considerations associated with alfalfa leaves:


Alfalfa contains compounds called psoralens that can make the skin more sensitive to sunlight. Excessive consumption of alfalfa or high doses of alfalfa supplements may increase the risk of sunburn or skin rashes when exposed to sunlight.

Digestive Issues

Some individuals may experience gastrointestinal discomfort, such as gas, bloating, or diarrhea, when consuming large quantities of alfalfa leaves or supplements. This is often due to the fiber content in alfalfa.

Hormonal Effects

Alfalfa is a source of phytoestrogens, which are plant compounds that can mimic the hormone estrogen in the body. While this can be beneficial for some individuals, excessive consumption of alfalfa may have hormonal effects and could potentially interfere with hormone-sensitive conditions or medications.

Allergic Reactions

Allergic reactions to alfalfa are rare but can occur in some individuals. Symptoms may include itching, skin rashes, swelling, or difficulty breathing. If you suspect an allergy to alfalfa, discontinue use and seek medical attention.

Medication Interactions

Alfalfa may interact with certain medications, including blood-thinning medications (anticoagulants) like warfarin. It could potentially affect the way these medications work, so it’s important to consult with a healthcare provider if you are taking medication and plan to consume alfalfa in larger quantities or as a supplement.

Autoimmune Conditions

Some individuals with autoimmune conditions, such as lupus, may want to exercise caution when consuming alfalfa, as its immune-stimulating properties could potentially exacerbate symptoms.

Pregnancy and Nursing

Pregnant or nursing women should use caution when considering alfalfa supplements because of its potential phytoestrogen content. Consult with a healthcare professional before use.

Thyroid Function

Alfalfa contains compounds called goitrogens, which can interfere with thyroid function in large amounts. If you have a thyroid condition or are taking thyroid medication, consult with your healthcare provider before adding alfalfa to your diet.

Kidney Stones

Some individuals with a history of kidney stones may want to limit their alfalfa intake, as it contains oxalates, which can contribute to the formation of kidney stones in susceptible individuals.

It’s important to consume alfalfa in moderation and be aware of any potential interactions with your health condition or medications. If you’re considering using alfalfa supplements for specific health purposes or have concerns about its safety, it’s advisable to consult with a healthcare provider or a registered dietitian who can provide personalized guidance based on your individual health and dietary needs.
