Depends where you go, definitely ask a doctor but I know that the one by me uses a product that's purely a DHA protein so I'm assuming its not bad but I'm gonna ask my doc too cuz I'm a pasty mofo, but you can go in a tanning bed, if you go 3 times a week for no longer then 8 min your fine ( depending on the bed), if stick with the lower beds that produce more UVB rays ( the burning rays) because they produce more vitamin d which is essential for the baby, the only danger factor
