Muscle tightness is caused by short, involuntary contractions of the muscles typically due to exercise. Vitamins work together with the other nutrients of the body to improve absorption, circulation and overall function of the muscles, organs and tissues. A deficiency in any number of vitamins due to inadequate nutrient intake or an unbalanced diet may be part of the cause for poor functioning and tightness of the muscles.

Online-ambulance.com explains that while the direct cause is unknown, deficiencies in B vitamins like thiamine, pantothenic acid and pyroxidine have been linked to muscle cramping and tightness. B vitamins are important in the body because they increases the efficiency of oxygen utilization in the muscles. Fortified cereals, poultry, red meat and fish are good food sources for B vitamin consumption.
Vitamin C increases the absorption of minerals in the body that are used for muscle contraction including calcium, iron and magnesium. A deficiency in vitamin C, therefore, can inhibit proper muscle function and cause muscle tightness or cramping. You can obtain vitamin C from citrus fruit, broccoli, brussel sprouts, strawberries, cabbage and spinach.
A common deficiency found in older people, Vitamin D can help discomfort and aching in the muscles. Vitamin D also helps in the absorption and utilization of calcium in the blood, which is required to soften and relax the muscles when they begin to cramp or tighten. The main source for vitamin D is from direct sunlight. You should get at least 15 minutes of direct sunlight each day, as vitamin D is synthesized in the skin from ultraviolet B-rays from the sun. Food sources rich in vitamin D include tuna and salmon.
Vitamin E is commonly known for its antioxidant value. Vitamin E protects the tissues in the body from damage done by toxins. Vitamin E also protects muscle strength, and one symptom of vitamin E deficiency is muscle cramping. Vitamin E can be found in vegetable oils like olive oil, nuts and dried fruits, fresh fruit, vegetables and some meats.
