The 11 Body Systems – The Muscular System

Posted on |

Why is the muscular system important?

The muscular system allows the body to move. It works by providing for the contractions that move bone ends closer to one another (the ‘closing’ of joints) which enables picking things up, moving things, and all forms of mobility. The contractions of the muscular system also aid the movement of food through the gut, provides a muscular ‘pump’ for the movement of lymph (waste and by-products of metabolism) back to circulation, and micro-contractions also aid the vascular system to properly distribute blood and help to control body temperature.

What is it made up of?

The muscular system is made up of the over 600 muscles of the human body.

How can I support the health of the muscular system?

Protein

Protein is the king of nutrients for supporting the muscular system and few people get enough protein to support muscle loss as they age, (3) or to support optimal body composition (the fat-to-muscle ratio). Although ‘food comes first’ many people do not get sufficient protein from diet alone (and, there is only a small amount in Good Green Stuff). The benefits of additional protein includes greater lean mass and less fat mass, (4-8) increased strength and power, (4) and improved lipid profiles, increased immunity and reduce infections. (11-13)

Note: To boost protein intake, take Nuzest Clean Lean Protein.

Vitamin B1 – Thiamin

Thiamin is critical to the body’s ability to liberate energy from carbohydrate and to utilize protein for muscle building.  Around 20% of people do not meet their B1 requirements from diet alone. (9)

Vitamin D

Reviews of the available research have suggested that vitamin D (at dosages > 600iu per day) improves muscular strength. (68, 69)

Magnesium

than 300 enzymes require magnesium ions for their actions, including all enzymes using or synthesizing adenosine triphosphate (ATP), the most basic fuel for all functions of the body, including muscle contraction and ATP is found in muscle as magnesium-ATP. Research suggests that almost half of the population do not consume the required daily amount of magnesium from food. (122) Magnesium supplementation is likely to improve strength in those with low dietary intakes and poor magnesium status. (130)

Potassium

Potassium is an electrolyte and the major cation in the intracellular fluid that is essential for normal cell, nerve, and muscular function.

Zinc

Zinc is an essential mineral that is required for the function of hundreds of enzymes and thousands of transcription factors in the body. Zinc supplementation might improve body composition (the ratio of muscle-mass vs fat mass). (157)

Lecithin

Lecithin contains phospholipids such as phosphatidylserine, phosphatidylcholine, and phosphatidylinositol (PI), substances that help form the cell-membrane and provide choline, a precursor of acetylcholine, the major neurotransmitter used for communication between the brain and central nervous system and muscle cells.

Shiitake

Shiitake is a medicinal mushroom with a long history of use in Asia for a range of conditions. Recent research has suggested that shiitake might aid muscle function by improving glycogen (stored carbohydrate) reserves. (280)
