Those alternatives either work poorly (vitamin D supplementation) or have other side-effects (hypertension drugs). And, as noted in the article, sun exposure is a complex reaction with several benefits - it would take many drugs to reproduce that effect.

Dermatologists are focused on skin health and more likely to overlook or ignore those other benefits.
