Lemon Zest liquid format distinguishes Liquid Liposomal NAD+ for Cellular Health – 100 MG – Lemon Zest (4 fl. oz./30 Servings) from capsule products discussed under cellular-health themes. The title states a four-fluid-ounce bottle and thirty servings. Read the exact ingredient panel and measuring instructions rather than treating bottle volume as the amount of NAD+ supplied. Cellular Health is product positioning, not evidence that the formula extends lifespan or produces a predictable personal effect.
