What is CBD?

CBD is everywhere. You may have seen it in gas stations and even at your local coffee shop.

But what is it exactly?

CBD stands for cannabidiol, the most well-known of 100+ phytocannabinoids in the hemp plant.

Hemp is a type of cannabis, a plant used for medicinal and other purposes for thousands of years.

Phytocannabinoids are plant-derived compounds that interact with cannabinoid receptors in your body’s endocannabinoid system (ECS). So, yes, your body is set up to receive cannabinoids, like CBD!

Phytocannabinoids are also found in other plants, like black pepper, oregano, and cocoa bean, though not in significant amounts.1

You might not have heard of it before… But, your endocannabinoid system helps bring balance to your body.

Scientists only discovered it in the early 1990s, while researching the cannabis plant and how it interacts with the brain.  

This system plays a significant role in how your body responds to stress — and regulates important functions, like immunity, sleep, mood, digestion, inflammation, pain, and memory.2

CBD is non-intoxicating, so it promotes wellness without getting you high.

Ultimate Serum uses the highest quality CBD for all its products.

What is hemp?

Hemp is a type of cannabis plant, like marijuana. But each plant has a different chemical makeup.

Hemp is cultivated to be high in CBD and low in THC (less than 0.3%), while marijuana is bred to have higher levels of THC.

Humans have used the hemp plant for thousands of years.

Hemp stalk and seeds can be used to make paper, clothing, construction material, and more.

Hemp oil, which you might see at the grocery store, comes from the seeds. It offers nutritional benefits, but doesn’t have phytocannabinoids, which interact with your body’s endocannabinoid system for balance and wellness.

Hemp CBD oil comes from the flowers, or buds, of the plant.

Ultimate Serum always gets its CBD from organically grown hemp plants. You can enjoy benefits without the high.

How Is CBD Oil Made?

CBD can be extracted from hemp plants (flowers) in multiple ways.

Unlike many CBD companies who use cheaper solvents (which may leave impurities in the final product), Ultimate Serum uses the gold standard method in the industry, CO2 extraction.

Carbon dioxide, CO2, is naturally occurring. Even your body produces it!

The process is clean, kills harmful bacteria, and ensures more beneficial cannabinoids and terpenes end up in the CBD oil. It’s safer for the environment, too.

You have many choices for CBD products, and not all hemp CBD is created the same. For the highest quality for your health, choose Ultimate Serum.

What Science Says

How does CBD work in your body?

It interacts with your endocannabinoid system (ECS). 

You probably haven’t heard about the ECS. Your doctor might not even know about it. 

Scientists only discovered it in the early 1990s, while researching the cannabis plant and its effects on the brain. 

You have ECS receptors almost everywhere — from your brain to your skin, immune cells, bone tissue, fat tissue, liver, pancreas, skeletal muscle, heart, blood vessels, kidneys, and GI tract. 3

So, it makes sense that your endocannabinoid system is involved in many major functions of your body, such as:4 

  • Mood and emotion 
  • Stress response
  • Immune function
  • Inflammation
  • Digestion
  • And memory

When your body becomes unbalanced — due to poor diet, lack of exercise, and other factors — and the ECS is unable to bring it back to “just right”... diseases and other health challenges may happen. 

That’s where the power of CBD comes in. 

CBD interacts perfectly with your ECS to bring balance to your body and mind.

Science shows that imbalance in the endocannabinoid system is connected to nearly all diseases affecting humans.

So, your ECS defines your health and well-being — it’s that important!

High-quality CBD products influence your health in a clean, non-toxic way. Choose Ultimate Serum for the ultimate CBD experience.
