See below: Vit a is important in bone growth, but too much vit a can actually cause bone loss (by increasing the osteoclasts which help with remodeling and breakdown). Retinol is the form, which if overconsumed, can lead to bone loss. This is found in anti-acne meds, psoriasis meds and others. Generally, stay below 10, 000 iu of retinol. Beta-carotene, another form of vit a, is considered safe for the bone.
