Anemia symptoms can negatively affect your exercise routine such as fatigue, shortness of breath, muscle weakness, feeling fatigued during exercise, nausea, diarrhea, dizziness, difficulty keeping up. balance and irregular heartbeat.

People who are most likely to have a vitamin B deficiency:

  • In the elderly, because the body produces less internal factors such as protein for the digestive system to absorb vitamin B12.
  • Women who are and are about to become pregnant need a higher than normal amount of vitamin B9, to support the developing fetus.
  • People who take antacids, using these drugs for a long time will deplete vitamins B9 and B12.
  • People with stomach complications such as celiac disease … make the body not absorb the necessary nutrients.
  • Those who are vegetarian or have an unbalanced diet, are less likely to supplement with foods rich in B vitamins.

People with stomach problems often find it difficult to absorb food and therefore lack some essential nutrients such as vitamin B

Foods rich in vitamin B9 for exercisers:

  • Dark green vegetables (broccoli, spinach, spinach, etc.)
  • Internal organs (liver, kidney, etc.)
  • Whole grains (rice, barley, wheat germ, etc.)
  • Fruits and juices (especially oranges and orange juice)
  • Nuts (sunflower seeds, cashews, flax seeds, etc.)

  • Eggs, milk and dairy products
  • Shellfish (oysters, clams, scallops, etc.)
  • Whole grains (brown rice, buckwheat, wheat…)
  • Meats, fish (beef, tuna, salmon…)

With the exception of mushrooms and grains, most foods rich in vitamin B12 are of animal origin. That’s why vegetarians are more likely to be deficient in this vitamin. However, if the vegetarian diet is still balanced with nutrition and sufficient nutrients, it will not affect the exercise.

Adults need about 400mcg vitamin B9 and 2.4mcg vitamin B12 per day.

This does not necessarily mean that vegetarians cannot exercise. The American Council on Exercise explains that vegetarian diets may be safe to promote physical activity, but those who are following them need to monitor their diets carefully.
