The thyroid is a gland about the size of a walnut that sits in the front of the neck. It releases hormones that are key to metabolism, temperature regulation and energy production. When thyroid function is low, it is called hypothyroidism and produces symptoms such as lethargy, weight gain and constipation. Conventional medications are commonly used to treat low thyroid function, but it can also be treated naturally.
Step 1
Avoid certain foods. There are various foods that can have a negative effect on the thyroid, and they should be avoided. They are called goitrogenic foods, and some examples of these are rutabaga, cabbage, Brussels sprouts, cauliflower, soy beans and kale.
Step 2
Increase your iodine intake. Iodine is a nutrient that is important for thyroid health and function. It can be found in foods such as seafood, potatoes, oatmeal, sea vegetables, yogurt and parsley.
Step 3
Take some natural supplements. There are several supplements and amino acids that can help improve the function of the thyroid. Some of these include bladderwrack, tyrosine, selenium and thyroid glandular.
Step 4
Try some herbal formulas. Kelp and Irish moss are herbal remedies that can be used together. They can help the body detox, increase circulation, improve metabolism and increase the activity of the thyroid.
Step 5
Get some exercise. Exercise is already known for its many benefits to the body, and it can also benefit the thyroid. Aim for 30 to 45 minutes of exercise five or more days a week. Some examples are weight training, running, biking, swimming and walking.
