The main causes of fatigue and lethargy are lack of iron, alkali and vitamins.

The following is a detailed introduction:

● Iron deficiency fatigue: manifested as drowsiness, fear of cold, decreased attention and resistance, etc. Girls who want to go on a diet because of slimming are often "caught" because they refuse to eat meat and staple food.

● Alkaline fatigue: manifested as memory loss, backache and leg pain, dizziness, insomnia, etc. This is all caused by acidic constitution. Irregular living habits will gradually turn the constitution into acidity. Exercise and sweating can take away a lot of acidic substances in the body!

● Vitamin deficiency fatigue: the most obvious manifestation is weakness of limbs, even if you do housework, you will be extremely tired. Appropriate supplementation of B vitamins can immediately improve this annoying situation.
