Abstract
Due to their active and stressful life, military personnel needs special nutrition. Nutritional supplements are meant to complement a healthy diet that includes vitamins, minerals, medicinal plants, amino acids, enzymes, and macronutrients. The depletion of muscle and liver glycogen reserves leads to a decrease in concentration, fatigue, and a decrease in physical and mental performance. Moderate to vigorous physical activity, one to three hours per day, requires 6 to 10 grams of carbohydrates per kilogram of body weight. It has been shown that the consumption of fat, including a high dose of conjugated linoleic acid (CLA) and omega-3, is effective in testosterone production, an issue that can be important for active people such as military forces due to the anabolic effects of testosterone. In people with vigorous physical activity, it is recommended to receive 1.4 to 2 grams of protein per kilogram of body weight, which is higher than in general people. Also, branched-chain amino acids (BCAA) compete with tryptophan in crossing the blood-brain barrier, delaying the feeling of fatigue. Excessive amounts of antioxidants in the form of supplements in people with vigorous physical activity disrupt the adaptation to physical activity and are not recommended. Vitamin D, iron, and zinc are involved in many natural functions of the body, and due to the special conditions of the military forces, there is a possibility of a lack of these nutrients in these people. This deficiency can endanger a person's physical performance and even health. Therefore, special attention should be paid to their adequate intake in the diet. Caffeine, nitrate, and creatine are among the substances that are effective in delaying the feeling of fatigue and have attracted the attention of people with vigorous physical activity. These nutrients can help military personnel during operations and increase their efficiency. In general, getting enough nutrients is very important for military personnel. Due to the special conditions during military operations, it is not possible to receive meals that can provide all the necessary nutrients. On the other hand, due to vigorous physical activities, the rate of metabolism, as well as the loss of nutrients in these people, is more than in general people, which increases the amount of need. Therefore, in order for the military forces to be able to have their maximum efficiency and also to prevent injuries and diseases that can have great costs and consequences for a country, the use of nutritional supplements to improve the nutritional status of these people can be considered.

Abstract
Intermittent fasting in Islam, particularly periodic fasting, has demonstrated significant positive effects on metabolism, immune function, and physical health that may prove particularly valuable for ship crews undertaking extended maritime missions. The caloric restriction and altered feeding schedules characteristic of intermittent fasting have been shown to enhance immune function, increase longevity, reduce risk of autoimmune disorders, and inhibit cancer development. The World Health Organization recognizes the importance of spirituality in health, and intermittent fasting may serve as both a spiritual practice and health strategy. The fasting process stimulates innate and adaptive immunity through autophagy and stem cell activation, promoting production of new immune cells and improved immune responses. This mechanism holds particular relevance for ship crews exposed to harsh environmental conditions and mission-related stressors. By modulating glucose and lipid metabolism, fasting activates autophagy to clear abnormal cells while enhancing stem cell regeneration and immune system renewal. Studies indicate fasting reduces pro-inflammatory cytokines and suppresses cytokine storms, leading to decreased inflammation, improved immune health, and reduced risk of metabolic and cardiovascular diseases- benefits that may help maintain crew health and performance during prolonged missions. As a low-cost, accessible intervention, intermittent fasting offers broad potential for health optimization and disease prevention in maritime personnel.
