Vitamin D3

The “Sunshine Vitamin” has an enormous impact on our overall health. Vitamin D is a prohormone (a vitamin that converts into a hormone) that travels through your blood and tissues like a Wi-Fi signal. Once inside your cells, it enters the nucleus, turning on over 900 genes. Some affect bone metabolism, others suppress tumor formation, others reduce inflammation, and others are essential for creating and maintaining brain synapses. With our modern lifestyle, this vitamin is as essential as it is neglected: an estimated 1 billion people worldwide are deficient. 

Vitamin B12

Vitamin B12 is an essential vitamin involved in the metabolism of every cell in the human body. It works hand in hand with methylfolate to help repair your DNA and regenerate brain cells. Vitamin B12 is also a common deficiency. Since B-12 plays such a pivotal role in brain function, it comes as no surprise that dementia is considered a B-12 deficiency related disease.  While both folate and B12 are essential, getting too much of one can suppress levels of the other, so it’s best to take them together in the correct form and dose. Enter: Astreas.

Lion's Mane Mushroom

The Lion’s Mane Mushroom is king of the nootropic jungle. It’s been featured in a number of Alzheimer’s trials because of its ability to increase nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), proteins that stimulate production of new brain cells and strengthen existing ones. High levels of BDNF are also tied to a lower risk of cognitive decline. Now that’s a mushroom on a mission.


Choline: the reason grandma kept pushing liver onto your plate. Choline is a micronutrient critical for cognitive health. It’s a precursor of a neurotransmitter essential for memory, shown to optimize brain function and support memory in individuals with age-related memory impairment. While our bodies can produce choline on their own, they can’t produce enough for optimal cognitive health – unless you have a stable diet of liver and egg yolks. Grandma knows best after all.  

Vitamin K

Vitamin K may be best known for its role in blood clotting and the calcification of bones, but more recent evidence suggests there’s much more than meets the eye. Increasing your vitamin K intake is one of the most sensible things you can do to lower risk of age-related chronic disease and extend your lifespan. What’s more, Vitamin K works synergistically with Vitamin D - each function more effectively in the presence of the other. The perfect pairing.


In today’s modern world, zinc deficiency affects almost all of us. An estimated 2 billion people are deficient. Zinc is found in high concentrations in only a few foods, like oysters and red meat. Your body does not store it, so consumption is vital for your health. Astreas empowers your health by giving your body the zinc it needs and deserves.
