Why Our Hair + Energy Formula Actually Works

Our Hair + Energy formula contains a therapeutic dose of Iodine:

Why have we chosen to include iodine?

Iodine is a nutrient responsible for the production of T3 and T4 thyroid hormones which contribute to regulating the function of our thyroid. These thyroid hormones impact pathways that regulate energy balance through controlling energy storage and use. Iodine also helps to support a healthy metabolism and is required for healthy brain development. 

 

We don't want an Iodine deficiency

Iodine deficiency doesn’t just cause one single disease, instead it results in many disorders such as hypothyroidism (a low production of thyroid hormones), birth complications, a goiter (abnormal enlargement of the thyroid) or slow growth and development in children. 

 

How it's metabolized in the body:

Iodine is cleared from circulation predominantly by the kidney, thyroid and renal clearance. The thyroid retains approximately 60 μg of iodine per day to regulate iodine loss and maintain the synthesis of thyroid hormones. A healthy adult has 10-20 mg of iodine and 70-80% of that lies in the thyroid. 

 

Where Iodine comes from:

The geographic availability of iodine is due to the impacts of flooding, glaciation and soil, so iodine is found mainly in coastal areas, which is why the highest sources of dietary iodine are found in seafood. One of the richest sources being Kelp, which is why we chose to add this into our vitamin. 

 

And There's Zinc

Why have we chosen to include Zinc? 

Zinc is an essential trace element, meaning the body cannot produce it on its own. So we as humans require it through diet or supplementation. Zinc is powerful for facilitating the recovery of hair follicles and is necessary for growth. Alopecia is one of the main signs of zinc deficiency with regrowth appearing after supplementation. 

 

What happens when we don't take enough Zinc

Zinc deficiency is more common in areas of low animal food intake. The diet may not actually be low in zinc, but individual bio-availability plays a role in absorption. Phytic acid (found in many plant seeds such as beans, grains, nuts and seeds) is a known inhibitor of zinc absorption. Groups most at risk of zinc deficiency include infants and young children, pregnant and lactating women. 

 

How is Zinc metabolised in the body?

Zinc is absorbed in our small intestine and our level of zinc may impact how well we absorb it. Those more deficient in zinc, absorb it with more success than those who consume an adequate amount of zinc through their diet. 


Where else can I find Zinc?

Some of the highest sources of zinc include oysters, beef, fortified breakfast cereals, beans, pumpkin seeds, nuts and chickpeas.
