Vitamin B1 and B2: Potential Benefits

Not all nutrients have the same degree of popularity. For every rockstar like vitamin D there’s a lesser known nutrient which hasn’t had its moment in the spotlight. Two such nutrients are vitamins B1 and B2 and today I will attempt to touch on some of the reasons you may want to consider your intake of these vitamins.

Vitamin B1 (thiamine)

In a study on 20 young women a daily 50mg thiamine supplement for 2 months increased reaction time (1). An older study from the 1940’s on children in an orphanage found that children given a 2mg thiamine supplement, compared to children given a placebo, had greater improvements in a number of markers of intelligence and memory (2).

Very high dose thiamine supplements have also been shown to improve blood sugar control in type 2 diabetics (3-5).

Vitamin B2 (riboflavin)

Some evidence suggests riboflavin (vitamin B2) prevents migraines (6-10). One randomized study lasting 3 month reported a reduced rate of migraines due to a daily 400mg riboflavin supplement compared to a placebo (10). However a randomized trial on 48 children reported no benefit from riboflavin on migraine risk (11). A similar study on children also found no benefit on migraines from riboflavin, but did observe reduction in tension headaches (12).

Finally, a study in over 2000 people in the Hebei province of China found that riboflavin supplemented salt, compared to un-supplemented salt, reduced the risk of esophageal squamous cell cancer and non-significantly reduced the risk of all esophageal cancers (13).
