”Dr. Holick’s ties to the tanning industry also have drawn scrutiny. Although Dr. Holick said he doesn’t advocate tanning, he has described tanning beds as a “recommended source” of vitamin D “when used in moderation.” Dr. Holick has acknowledged accepting research money from the UV Foundation — a nonprofit arm of the now-defunct Indoor Tanning Association — which gave $150,000 to Boston University from 2004 to 2006, earmarked for Dr. Holick’s research.

The database includes only payments made since 2013, but Dr. Holick’s record of being compensated by drug companies started before that."
