People eat alfalfa fresh in the form ofsprouts.
It has a sweet, bitter, grassy flavor.

In plants, they exist to protect them from infection and from getting destroyed by insects.
Anti-nutrients can also offer health benefits.
Whether it can achieve the same effect in humans is uncertain.
As such, alfalfa may be supportive fordiabetesorprediabetes.
There has been some evidence of this in animal studies.
Treatment groups were given an extract of alfalfa.
Therefore, it is unclear whether it can achieve the same benefits in humans.
Further research is needed.
Free radicals trigger oxidative stress, which can increase disease and aging in our cells.
Antioxidants, like those found in alfalfa, help prevent free radicals from harming the body’s cells.
May Relieve Menopausal Symptoms
Alfalfa contains a group of molecules calledisoflavones.
These are a bang out ofphytoestrogen, a plant-based hormone that mimics the action of the hormoneestrogen.
The participants took the extracts of these plants for three months.
Another study looked at the effects of botanical supplements on hormonal symptoms in 788 participants with breast cancer.
Participants answered a survey about their symptoms.
Those who used alfalfa were less likely to report disturbed sleep than those who did not use alfalfa.
However, this was an exploratory study and did not include controls or comparisons.
Alfalfa was the most commonly used herb, followed by black seed and fenugreek.
