5 muscular functions & how vitamins and minerals are related

The Role of Vitamins and Minerals in Muscle Health

We can credit our body’s ability to move to the muscles that surround and connect to our bones, joints, organs, and blood vessels. Without muscular movement, we would not be able to walk, hold things, talk or even breathe! It's thanks to our highly advanced muscular skeletal system that we are able to do the everyday things we often take for granted - such as talking, running, hugging, blinking, laughing and more. What are the exact functions of our muscles though? And exactly how do our muscles stay in tip top condition? Read on to understand more about different types of muscles, such as skeletal muscles and smooth muscles, the muscular system and muscle function, as well as what role vitamins and minerals play in healthy muscular function.

Types of Muscles

There are 3 types of muscles: cardiac muscles, skeletal muscles and smooth muscles. Each type of muscle has their own necessary function in the human body.

Cardiac muscle: Specifically related to the heart and functioning of the heart, these muscles contract at a regular rate to keep blood flowing to the heart.

Skeletal muscle: This muscle type attaches bones by tendons and are responsible for movement of body parts.

Smooth muscle: These muscles help regulate the flow of blood through the arteries, and helps food through the digestive system.

Importance of Muscle Health

The muscles in the human body have various jobs which assist the body to function as it should, and allow us to live healthy and well-rounded lives. Healthy bones and healthy muscles are part of the key to a long and happy life. Each muscle or muscle group performs certain activities in order for us to walk, breathe, talk, and so on. There are, in general, five important functions for muscles to perform, which we will take a look at now.


The skeletal muscle is the largest organ in our body and is referred to as a voluntary muscle, the function is contraction which results in movement, posture, and stability.


The organs in our body would not be able to function if it weren't for muscles that support them. These muscles allow the organs to perform the functions they need to in order for us to live. Think of the lungs - we wouldn't be able to breathe if it weren't the diaphragm and the muscles between the ribs, contracting and relaxing, causing the lungs to expand and contract and give our body air.


The muscular system consists of many different muscles with various jobs to perform. Some muscles in our body, such as our abdominal muscles, hold organs in place to support your body during movement.

Blood Circulation

We wouldn't be able to function if it weren't for the heart, which contracts at a regular rate to keep blood flowing to the heart.

The Essential Vitamins

Vitamins play crucial roles in maintaining overall health, and certain ones are particularly important for muscle health.

Vitamin D, often referred to as the "sunshine vitamin," is essential for calcium absorption and bone health. Adequate levels of Vitamin D contribute to muscle strength and function, preventing conditions like muscle weakness and pain.

Vitamin Cknown for its antioxidant properties, is vital for collagen synthesis, a protein that provides structure to muscles, tendons, and ligaments. Additionally, Vitamin C supports the immune system, helping to protect muscles from inflammation and oxidative stress that may occur during intense physical activity.

Vitamin E, another potent antioxidant, plays a role in protecting cell membranes from damage caused by free radicals generated during exercise. This vitamin aids in maintaining optimal muscle function by reducing oxidative stress, which can contribute to muscle fatigue and injury.

How Vitamins Contribute to Muscle Strength, Flexibility & Recovery

Vitamins D, C, and E collectively contribute to muscle strength, flexibility, and recovery through their distinct roles in various physiological processes. Vitamin D aids in the absorption of calcium, crucial for bone health and muscle contraction. Adequate levels of Vitamin D can enhance muscle strength by promoting optimal calcium utilization, reducing the risk of muscle weakness and fatigue.

Vitamin C, with its role in collagen synthesis, supports the structure of muscles, tendons, and ligaments. This not only enhances flexibility but also helps prevent injuries by maintaining the integrity of connective tissues. Furthermore, Vitamin C's antioxidant properties combat oxidative stress, reducing inflammation and promoting a faster recovery process after strenuous physical activities.

Vitamin E, being a potent antioxidant, protects cell membranes from oxidative damage during exercise, contributing to muscle recovery. By mitigating the effects of free radicals generated during intense physical exertion, Vitamin E supports overall muscle health and aids in minimizing post-exercise soreness.

In summary, Vitamin D supports muscle strength, Vitamin C contributes to collagen formation and immune function, while Vitamin E helps protect muscles from oxidative damage, collectively promoting overall muscle health and performance. It's important to maintain a well-balanced diet to ensure an adequate intake of these vitamins for optimal muscle function and recovery.

Minerals and Muscle Function

Essential minerals such as calcium, magnesium, and potassium play crucial roles in the intricate processes of muscle contraction and relaxation. Calcium is a key player in muscle contraction; it binds to proteins within muscle cells, triggering a series of events that lead to the shortening of muscle fibers. This process is fundamental for various physiological functions, including movement and strength.

Conversely, magnesium acts as a natural muscle relaxant by counteracting the effects of calcium. It competes with calcium for binding sites on proteins within muscle cells, helping to regulate muscle contractions and prevent excessive tightness. Magnesium deficiency may contribute to muscle cramps and spasms due to an imbalance in the calcium-magnesium ratio.

Potassium, on the other hand, is essential for maintaining the resting membrane potential of muscle cells. It plays a crucial role in repolarization after a muscle contraction, allowing the muscle to relax. Adequate potassium levels support smooth and coordinated muscle function, preventing issues such as muscle weakness or prolonged contractions.

How Mineral Deficiencies Can Impact Muscle

Mineral deficiencies can significantly impact muscle performance and give rise to issues such as cramps and fatigue. A lack of calcium, a key mineral in muscle contraction, may result in compromised muscle strength and coordination, leading to increased susceptibility to cramps and spasms. Inadequate magnesium levels can disrupt the delicate balance with calcium, potentially causing muscle tightness, cramps, and prolonged contractions.

Potassium deficiency can impair the proper repolarization of muscle cells after contraction, contributing to muscle weakness and increased fatigue. Insufficient potassium levels may also hinder the muscles' ability to recover, prolonging the duration of fatigue after physical activity.

These mineral imbalances disrupt the intricate processes of muscle contraction and relaxation, compromising overall muscle function. As a consequence, individuals with mineral deficiencies may experience decreased exercise performance, increased susceptibility to muscle cramps, and persistent feelings of fatigue. Maintaining a well-balanced diet that includes these essential minerals is crucial for supporting optimal muscle health and preventing performance-related issues.

How Food Contributes to Muscle Health

The body gains energy from food, and this in turn is generally what allows us to function normally. As we know, the body is a living organ that needs minerals in order to survive and function well. Food that is rich in nutrients is recommended for muscles to function properly. This means including foods that have vitamins and minerals.
