Ultra K Supplement: Vitamin K, Vitamin D & Astaxanthin's Role in Muscle Recruitment
Muscle recruitment is the neurological process of activating additional motor units to generate more force inside a muscle. When your nervous system signals a muscle to contract, it relies heavily on precise electrolyte firing, neurochemical signaling, and instant cellular energy. By combining Vitamin K, Vitamin D, and Astaxanthin, you are significantly enhancing motor unit firing efficiency and muscle fiber responsiveness — through distinct biological mechanisms.

Muscles generate the force that creates speed during exercise. Muscles benefit from nutrients that complement their biochemistry.
