Evidence-Based Protocol

Supplement stack ranked by research quality

Limited Evidence

Primary Stack (Tier 1)

2-4g daily in divided doses

May help counteract some hyperthyroid symptoms; studied in Graves' disease

5 studies | 200 participants
200mcg daily

Supports thyroid function; studied in Graves' disease and thyroid eye disease

8 studies | 400 participants

Supporting Stack (Tier 2)

2000-4000 IU daily

Often deficient in autoimmune thyroid disease; supports bone health

6 studies | 300 participants
1000-1200mg calcium daily

Bone loss accelerated in hyperthyroidism; supports bone density

6 studies | 300 participants
300-400mg daily

Depletion common in hyperthyroidism; supports muscle and nerve function

4 studies | 150 participants

How It Works

Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, speeding up the body's metabolism.

COMMON CAUSES:

Graves' disease (autoimmune - most common)
Toxic nodular goiter
Thyroiditis
Excessive iodine intake
Overmedication with thyroid hormone

SYMPTOMS:

Rapid heartbeat, palpitations
Weight loss despite increased appetite
Nervousness, anxiety, irritability
Tremor
Increased sweating
Heat intolerance
More frequent bowel movements
Fatigue, muscle weakness
Sleep problems
Thin skin, fine hair
Menstrual changes
Eye problems (Graves' disease)

CRITICAL: Hyperthyroidism requires medical treatment.

MEDICAL TREATMENTS:

Antithyroid drugs (methimazole, PTU)
Radioactive iodine (destroys thyroid tissue)
Surgery (thyroidectomy)
Beta blockers (symptom control)

COMPLICATIONS IF UNTREATED:

Heart problems (atrial fibrillation, heart failure)
Bone loss (osteoporosis)
Thyroid storm (life-threatening)
Eye problems

* L-carnitine may help with some symptoms.

* Selenium supports thyroid health.

* Medical treatment is essential.

Expected timeline: Antithyroid medications work over weeks to months. Supplements provide supportive benefit during treatment.

Weight Loss & Maintenance

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.

Type 2 Diabetes

1 shared supplement · 868 outcomes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

Type 1 Diabetes
