Primary Stack (Tier 1)

300-600mg daily (standardized root extract)

Stimulates thyroid hormone production by enhancing T4 to T3 conversion and directly supporting thyroid gland function through adaptogenic mechanisms

1 studies | 50 participants
2-4g daily in divided doses

Improves cellular energy metabolism, reduces fatigue symptoms, and may help normalize thyroid hormone action at the cellular level

How It Works

Hypothyroidism occurs when your thyroid gland doesn't produce enough thyroid hormones (T3 and T4). These hormones control your metabolism—the process by which your body converts food into energy. When thyroid hormones are low, everything slows down: you feel tired, gain weight easily, feel cold, and may experience depression, brain fog, and dry skin.

•Ashwagandha is an adaptogenic herb that has shown promise for supporting thyroid function. In a study of people with subclinical hypothyroidism (mildly low thyroid function), ashwagandha significantly increased levels of both T3 and T4 hormones while normalizing TSH (thyroid-stimulating hormone). It appears to work by reducing stress hormones like cortisol that can suppress thyroid function, and by directly stimulating the thyroid gland.
•L-Carnitine helps your cells produce energy more efficiently. Many people with hypothyroidism experience profound fatigue because their cells can't generate energy properly. L-carnitine helps transport fatty acids into mitochondria for energy production. Studies show it can improve fatigue, body composition, and metabolic markers in hypothyroid patients.

Expected timeline: Ashwagandha typically shows effects on thyroid hormones within 8 weeks of consistent use. L-carnitine's energy-boosting effects may be noticed within 2-4 weeks.

Important notes: These supplements are meant to support—not replace—thyroid medication if you've been prescribed it. Always work with your healthcare provider to monitor thyroid function with blood tests. Selenium and iodine are also important for thyroid health but should be used cautiously based on individual needs.

Weight Loss & Maintenance

2 shared supplements · 433 outcomes

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

2 shared supplements · 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.

Running Performance

This goal refers to outcomes specifically related to running, such as running speed and endurance. Related faculties are muscular endurance, cardiovascular and pulmonary health, and conditioning.

Overweight

2 shared supplements · 379 outcomes

Overweight is characterized as having a body mass index (BMI) of 25 to 29.9. Having overweight is associated with increased risk of conditions such as cardiovascular disease. However, this may not be the case in people with increased lean mass (e.g., athletes or weight lifters).

Osteoarthritis (OA)

2 shared supplements · 116 outcomes

Osteoarthritis (OA) is a joint disease involving cartilage degradation. It’s not clear what exactly causes OA, but some risk factors include joint injury, overweight or obesity, aging, misaligned joints, and family history. Lots of supplements have been studied in people with OA, as have lifestyle interventions including weight loss and exercise.

Oligospermia

Oligospermia is a condition of male infertility characterized by a low sperm count. A sperm count below 15 million sperm per milliliter of semen is considered as oligospermia.

Obesity

2 shared supplements · 525 outcomes

Obesity is a condition of excessive body fat that increases the risk for other conditions such as diabetes and heart disease. Fat is how the body stores extra calories that were eaten but not used. Obesity treatment usually involves restricting the calories eaten or creating a negative calorie balance.
