Known as intranasal peptide sprays, this method alters the delivery and absorption of peptides
The same is true of B vitamin complex supplements, which deliver 50 to 500 micrograms (i.e., 20 to 200% of the RDA), as well as for most supplements containing only vitamin B12, which deliver up to 1,000 micrograms (about 400% of the RDA)
Stacked alongside other supplementssuch as NAD+ boosters, magnesium glycinate, or adaptogensit adds another dimension to a daily protocol that supports the body from the inside out
Risk assessment should therefore focus on route, allergy history, skin conditions, wound status, immune status, medications, pregnancy, breastfeeding, and whether the product is cosmetic, compounded, or investigational [7], [8], [11]
