How to increase your blood oxygen naturally?

The consumption of Tetraselmis Chuii (in Living Buddha®) for 1 month obtained similar or higher results in Haemoglobin and Oxygen consumption when compared to a high-altitude or high-intensity training for at least three months.

That means:

1 Month Has The Effect Of 3 Months
Of Training At 3.000 M Altitude!

This is the conclusion of a clinical trial in Spain*.

Hemoglobin is a protein found in red blood cells. These cells are responsible for carrying oxygen around the body. Higher oxygen uptake means fuel to muscles, which translates to improved performance and endurance.
