Everybody seems to be busy with something these days, so it’s not surprising to feel fatigued and tired at the end of the day. However, if that sluggish feeling doesn’t seem to go away with rest and becomes a daily occurrence, it could mean that you are lacking in certain vitamins and minerals.

Feeling tired all the time is not only physically dragging, but it can also affect how to deal with other people and your surroundings. Here are some of the vitamins that may be deficient in your body, contributing to that constant feeling of tiredness.

Magnesium

Magnesium is a popular supplement for those who want to fight fatigue, tiredness and poor sleep. Look for magnesium bisglycinate in particular because it is absorbed by the body faster.

Zinc

Zinc works best with magnesium and vitamin B6 to help the body relax. The recommended dose of zinc for adults is 30 mg per day.

Tryptophan

This essential amino acid does not naturally occur in the body, so we have to get it through supplementation and diet. Tryptophan is a precursor of vitamin B3, serotonin and melatonin, all of which assist the body in recovering from stress and fatigue.

Vitamin B-Complex

This combo helps the body power through tiredness and stress. It includes vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine hydrochloride), and B8 (inositol).

Iron

Iron is what keeps the blood pumping and is, thus, important to keep your energy levels high. Look for ferrous bisglycinate over ferrous oxide because the former has 24 percent iron content and is absorbed faster and better by the body.

Vitamin B12

This vitamin plays an important role in boosting energy levels in your body, and one of the telltale signs of a deficiency is lack of energy and fatigue. The typical daily requirement for Vitamin B12 is 1.8 mcg for older kids and 2.4 mcg for adults. Pregnant and breastfeeding women need more at 2.8 mcg and 2.6 mcg, respectively.
