Vitamin B5 · 50 mgRiboflavin · 50 mgThiamin · 50 mgVitamin B12 · 50 mcg
Riboflavin, niacin, B6, B12, folate and pantothenic acid can help reduce tiredness caused by low intake or deficiency. Their normal metabolic roles do not establish an extra energy boost when nutrition is adequate. B12's 50 mcg serving was not included in the saved findings despite its known nutritional role. The remaining included vitamins provide substantial amount coverage without proving extra energy from higher intake.
