What the Scientific Literature Says
NAD+ declines with age; this is well-established. Precursor supplementation (NMN, NR) shows mixed clinical results. IV NAD+ has minimal controlled trial data. A 2023 meta-analysis of NMN found modest metabolic benefits. Long-term effects of supraphysiologic NAD+ levels unknown.

Spent $4k on NAD+ IVs over 6 months — honest review
Week-by-week journal + itemized cost. TL;DR: noticeable 2-3 day energy bump after each infusion, nothing durable. No biomarker changes I can point to. Would not repeat at this price.

Claims (grey reversal, presbyopia reversal) have no mechanistic or clinical basis.

Community Reports (2 displayed of 28)
Add yours3-month NAD+ IV protocol showed initial energy improvements during weekly loading phase that attenuated with monthly maintenance. Significant discomfort during infusions. Low confidence due to placebo-prone subjective outcomes and addition of NMN mid-protocol.
8-week sublingual NAD+ showed minimal subjective improvement in energy levels. User found the cost-benefit ratio unfavorable compared to claims. No objective data to supplement subjective assessment.
