Natural betaine is a universal substance made by your own body. There are several functions. Your body's natural production of betaine can be helped by eating betaine-rich foods.
Beets are high in betaine, and you get more betaine from eating beets than you get from ingesting betaine, which is synthetically made.
Drinking beetroot juice can have a positive effect on high blood pressure and help with cardiovascular problems.
In general, if you drink 500 milliliters of beetroot juice, your blood pressure will drop for an hour. It will continue to decrease over the next few hours and remain less after 24 hours.
Other natural sources of betaine include spinach, broccoli, shellfish, grapes, whole grains, beets, spinach, and various whole grains. Many red wines contain small amounts of betaine, as beets are often used to increase the alcohol content.
Here are some foods that are naturally high in betaine: rye flour and other whole grain flours, pasta — especially whole grain or vegetable-based foods, quinoa and other grains and cereals, beets and spinach — raw, cooked, or canned.
These are just a few natural ways that can help increase your body's need for betaine. People who experience a lot of stress may find that their bodies don't naturally produce enough betaine to cope.
You can buy betaine anhydrous and betaine hydrochloride (HCL) in the form of a beneficial powder that can be mixed with any liquid or food.
