Benefits of L-Lysine
being a small amino acid, L-lysine provides some significant benefits
to your body and overall health.
works to boost your immune system by up-regulating its performance.
This amino acid controls specific antibodies known as IgG. The levels
of these antibodies in the blood increases in the presence of
l-lysine. With more antibodies in the blood to identify and
neutralize pathogens, your immunity is stronger.

and bacteria. This is important support for your immune system. Poor
lifestyle choices, unhealthy diets, chronic stress, and antibiotics
can all weaken your immune system. When weakened, it is unable to
protect you from infection and disease. L-lysine supports immune
strength, by keeping your body clear of invading pathogens.

is activated at injury sites and can speed up the repair process by
producing collagen. It serves as a binding agent, bringing more cells
to the wound area and promoting the formation of new blood vessels.
combined with another amino acid arginine, studies found the healing
process of bone fractures is improved. Wound healing requires several
vitamins and minerals, but without l-lysine, the healing process
would be impaired.
sores are fluid-filled blisters that develop around the mouth.
They’re caused by the HSV-1 (herpes simplex virus type 1)
