A 12-week study on 71 women using GHK-Cu cream showed progressive improvement in collagen, with 70% of participants responding positively compared to 50% with vitamin C and 40% with retinoic acid (Pickart et al., 2015)
However, in a subanalysis of participants with low vitamin B 12 status at baseline (n= 101), the B-vitamin supplementation slowed the decline in bone mineral density (total hip and femoral neck but not lumbar spine) (116)
A study tracking patients on semaglutide for 12 months found mean vitamin B12 levels dropped from 567 to 494 micrograms per deciliter, a significant decline that happened quietly while patients focused on their shrinking waistlines
Mild adverse events were similar between treatment and placebo groups, including headache, fatigue, and gastrointestinal symptoms
Requires 24 weeks of consistent dosing to produce measurable changes in memory or learning tasks
