Understand What Powers C2K
At C2K, we believe that knowledge is the first step to lasting wellness.
Here, you can explore the science behind our ingredients — how they work, why they matter, and what makes C2K different.
Fucoidan is a natural compound extracted from brown seaweed, celebrated for its immune-boosting and cell-regenerating properties. It supports the body’s ability to protect against inflammation, promote cellular repair, and maintain overall vitality.
C2K Fucoidan is formulated with high-purity extract standardized for potency and produced under FDA, GMP, and NSF standards in the USA.
Nicotinamide Mononucleotide (NMN) is a vital precursor to NAD⁺ — a molecule essential for energy metabolism and DNA repair. As we age, NAD⁺ levels decline, leading to fatigue and slower cellular recovery.
C2K NAD⁺ supports natural energy production, promotes healthy aging, and helps the body maintain optimal vitality.
Health Starts from the Ground Up
Your feet are the foundation of your body, supporting movement, balance, and overall wellness. The PEMF Foot Care Device uses pulsed electromagnetic fields (PEMF) to stimulate circulation, reduce tension, and promote natural cellular repair from the ground up.
Who should use this device?
This device is ideal for individuals experiencing foot pain, heel pain, numbness, cold feet, or poor circulation. It's also beneficial for those with gout, arthritis, joint inflammation, stress, or insomnia. Seniors, sedentary individuals, and those who spend prolonged periods standing or wearing high heels can also benefit from this device.
Ideal for:
✔ Foot pain, heel pain
✔ Numbness, cold feet, poor circulation
✔ Gout, arthritis, joint inflammation
✔ Stress, insomnia
✔ Seniors
✔ Sedentary individuals, prolonged standing, high heels
Do NOT use if:
❌ You have a pacemaker
❌ You are pregnant
❌ You have acute high fever
FUNCTIONS OF THE PEMF DEVICE (Foot Therapy)
PEMF (Pulsed Electromagnetic Field) uses low-frequency electromagnetic waves to gently stimulate cells, helping to:
- Activate the body’s electromagnetic field and increase cellular energy
- Improve circulation and increase oxygen supply
- Relax muscles, reduce fatigue, inflammation, and joint discomfort
- Support the body’s natural recovery process
PEMF: Helps repair cells, reduce pain, and improve blood circulation.
THz (Terahertz): Deep heat waves promote vasodilation, enhance metabolism, and strengthen immunity.
Bluetooth: Allows connection to mobile devices or remote-control applications.
20 Levels (L1–L20): Adjustable intensity from mild to strong depending on user needs.
30-Minute Default: Optimal duration for one therapy session.
Terahertz (THz) is a high-frequency electromagnetic wave located between microwaves and infrared rays, ranging from 0.1 to 10 THz with wavelengths from 30 µm to 3 mm.
THz FUNCTION
Terahertz waves are considered “cellular energy waves” because their frequency matches the natural vibration frequency of water molecules and proteins in the human body.
When THz waves are applied to the body, they can activate water molecule movement, increase cellular vibration, and stimulate metabolic processes.
