Thyroid Health  –  Energy Production  –  Immune System Support  –  Vegan Friendly


Thiamin (Vitamin B1) (as Thiamin HCI) – 100mg

Thiamin, also known as Vitamin B1 is a critical energy nutrient involved in the conversion of food to energy, particularly carbohydrates. Thiamin also plays a key role in nerve, muscle, and heart function and is also essential for the body to metabolize glucose.

Severe B1 deficiency is called Beriberi and can impair heart function, although severe deficiency is rare. Moderate deficiency can be been linked to chronic fatigue, gut issues, neuro and muscular degeneration, heart muscle damage, edema, and problems with eye health.

Thiamin deficiency can also cause various symptoms including depression, irritability, abdominal pain, weakness, and fatigue. Some of the foods that are high in Thiamin include pork, fish, asparagus, and brown rice.

Riboflavin-5-Phosphate (Vitamin B2) – 75mg

Riboflavin-5-Phosphate is the most bio-available form of Vitamin B2. This vitamin is a powerful antioxidant which increases blood flow, protects the digestive tract, and is an important co-factor when taken with other B-Vitamins.

Vitamin B2 also helps with the Thyroid by aiding the production of the Thyroid Hormone T4. It also helps the Adrenal gland secrete hormones making it a critical component of overall health.

B2 is all about energy, it is used in our bodies for metabolism of fats, carbohydrates, and proteins, as well as for DNA and RNA metabolism. B2 maintains energy and is linked to healthy hair & skin. It also promotes the growth of organs, connective tissue, eyes, mucus membrane, and supports the immune system.

Niacin (Vitamin B3) (as Niacinamide) – 100mg

Niacin, also known as Vitamin B3 is used by your body to turn food into energy. It helps keep your nervous system, digestive system and skin health.

Niacin also helps with energy production as Niacinamide is a precursor of nicotinamide adenine dinucleotide (NAD), which is essential for oxidation reduction reactions, nutrient metabolism and ATP synthesis.

Important for health circulation, Niacin also supports the metabolism of carbohydrates, fats, and proteins. Some of the foods which are high in Niacin include Tuna, chicken, pork, avocados and brown rice.

Vitamin B6 (as Pyridoxine-5-Phosphate) – 10mg

Vitamin B6 works with iodine and helps with thyroid hormones production. It is known as a balancing vitamin which is important when it comes to energy, vitality, and mood.

Vitamin B6 also works as a co-factor involved in the synthesis of neurotransmitters like Serotonin, Dopamine, Epinephrine, Norepinephrine, and Gamma-AminoButyric Acid (GABA) which is why it is so important for mood and mental wellbeing. Meat, bananas, and dark chocolate can be great food sources of Vitamin B6.

Folate (as L-5-Methyltetrahydrofolate) – 400mcg

Folate (also known as Vitamin B9) is an essential nutrient, but especially when it comes to growth, the nervous system, and brain development. Folate is commonly found in prenatal vitamins due to the important for fetal development.

Folate also protects the heart by removing homocysteine, one of the causes of heart attacks. It is also involved in the control of cholesterol. One of the signs of folate deficiency is anemia which indicates how important it is.

Folate can be naturally found in foods such as spinach, beef liver, asparagus, leafy greens, and avocado.* The form of folate used in Pro-Throid™ (L-5-Methyltetrahydrofolate) is also more easily absorbed than folic acid.

Vitamin B12 (as Methylcobalamin) – 500mcg

Vitamin B12 is crucial to health, especially in the areas of metabolic and cellular processes, red cell blood production, nerve, and neurological function.

Although you don’t need much, Vitamin B12 deficiencies are surprisingly common, especially for people following plant-based diets as B12 is primarily found in meat, fish and dairy.

Vitamin B12 deficiencies generally happen one of two ways. Either a person is not getting enough B12 in their diet, or they are simply not metabolizing the B12 they are taking in.

Absorption issues can result from inadequate intrinsic factor (aka I.F, a protein secreted in the stomach which works with B12), digestive enzyme issues, or organ damage from chronic illness like Crohn’s Disease and Celiac Disease among others.

Symptoms of deficiency vary depending on severity. The most common include fatigue, constipation, decreased appetite, tingling in the hands and feet, impaired memory, depression, and soreness of the tongue.

Biotin – 1000 mcg

Biotin (named after the Greek word for life (biotos), is an essential micronutrient which allows us to break down other nutrients for the body to use. Your body needs biotin to regulate blood sugar, and to maintain a healthy metabolism.

It also plays an important role working with your thyroid to stabilize hormone production, and helps your body metabolize fats and carbohydrates. Common sources of Biotin are: meat, eggs, yeast, and avocados are all sources of biotin.

Pantothenic acid (as Calcium Pantothenate) – 60mg

Pantothenic Acid, also known as Vitamin B5 is a water soluble B-vitamin that plays a role in energy production, metabolism, and blood-sugar control. Pantothenic Acid helps to synthesize fat, carbs, and hormones like thyroid. adrenals, and sex hormones.

Pantothenic Acid is also a great immune system booster as it healps with gut health and the absorption of other nutrients. Pantothenic Acid is commonly found in foods like beef, chicken, beans, milk, and eggs.


Potassium Iodide – 150mcg and Iodine – 100mcg

Iodine & Potassium Iodide. When it comes to thyroid health, iodine is probably the most important nutrient as without iodine, the thyroid could not effectively produce thyroid hormones, however as the body does not make iodine, it must come from our food, or through supplementation.

When someone is iodine deficient, they will often grow a goiter, which is the enlargement of the thyroid as it reaches out trying to grab any iodine from the body it can.


Selenium (as L-selenomethionine) – 50mcg

Selenium comes from good quality soil and is a trace mineral, but is very important when it comes to thyroid health.

Selenium works with iodine to help the thyroid convert the inactive Thyroid hormone T4 to the active thyroid hormone T3, so it’s vitally important to have adequate levels in your body. Selenium is also important in helping the thyroid avoid producing excessive amounts of Reverse T3.

Selenium is also critical to Metabolism, is a powerful antioxidant, and immune booster, It helps with fertility, and even improves blood flow. Brazil nuts, eggs, tuna, cod, and liver are all known to be great sources of selenium.
