One of coffee's many benefits is its high nutrient profile of riboflavin (vitamin B2), niacin (vitamin B3), magnesium, potassium, and various phenolic compounds (or antioxidants).
Some of our favorite benefits from consuming high-quality coffee are:
Thyroid + Metabolic Support - the thyroid is the butterfly-shaped gland located in your neck that drives the metabolism. B1 or thiamine is a crucial cofactor for several enzymes involved in the conversion of carbohydrates into energy through glycolysis and the citric acid cycle (also known as the Krebs cycle). It also plays a role in the function of the mitochondria, the cellular structures responsible for energy production.
When the body is deficient in thiamine, it may lead to disruptions in these metabolic processes, potentially affecting overall energy levels and cellular function. Thiamine deficiency can be a cause of thyroid dysfunction.
Coffee has a thermogenic effect, meaning it increases the production of heat in the body. This effect contributes to the increase in metabolic rate. A well functioning metabolism is all about the heat!
“Coffee drinkers have a lower incidence of thyroid disease, including cancer, than non-drinkers.” - Dr. Ray Peat
“Coffee provides very significant quantities of magnesium, as well as other nutrients including vitamin B1” - Dr. Ray Peat

Liver Support - Coffee consumption has been linked to a reduced risk of liver diseases, such as fatty liver, cirrhosis, and liver cancer. It appears to have a protective effect on the liver, likely due to its antioxidant properties.
“Caffeine protects the liver from alcohol and other toxins” - Dr. Ray Peat
The liver has hundreds of important functions in the body, the most important being that it's the organ responsible for detoxification. Contrary to popular opinion, the liver is not a “filter”. Instead, it is the organ that supports healthy detoxification processes in the body. If the liver is not functioning properly, proper detoxification will not occur. Our liver needs to be in primary condition in order to support healthy detoxification of toxins and estrogen.
“Caffeine protects against cancer caused by radiation, chemical carcinogens, viruses, and estrogens.” - Dr. Ray Peat
“Caffeine synergizes with progesterone, and increases its concentration in blood and tissues.” - Dr. Ray Peat
“Cystic breast disease is not caused by caffeine, in fact caffeine’s effects are likely to be protective; a variety of studies show that coffee, tea, and caffeine are protective against breast cancer.” - Dr. Ray Peat
“Its niacin and magnesium are clearly important, but it is also a rich source of antioxidants, and it helps to maintain normal thyroid and progesterone production.” - Dr. Ray Peat
Blood sugar balance - The antioxidants and polyphenols found in coffee such as chlorogenic acid have protective effects on cells. Antioxidants help neutralize harmful free radicals in the body, which are implicated in various diseases, including diabetes. Polyphenols have a positive effect on glucose metabolism and insulin sensitivity. Chronic low-grade inflammation contributes to the development of insulin resistance and type 2 diabetes. Some studies suggest that the anti-inflammatory properties of coffee may help mitigate this risk. Coffee improves insulin sensitivity and research indicates that coffee consumption may enhance insulin sensitivity, making it easier for the body to use insulin effectively and regulate blood sugar levels.
“Drinking coffee seems to be very protective against developing diabetes.” - Dr. Ray Peat
Of course, we do not believe that coffee alone can replace a poor diet. However, we do believe that a very high-quality, nutrient-dense diet, paired with the consumption of high-quality coffee can be extremely beneficial.
