RGENR8 vs Renue by Science NMN
RGENR8 is a UK brand that ships from the UK. Renue by Science is US-based and ships to the UK. Here's how the two compare on dose, formats, delivery, returns and total cost to a UK customer.
Quick answer
RGENR8 and Renue by Science are unrelated companies in different countries. RGENR8 Pure NMN is a single-ingredient 500mg capsule, independently tested, shipped free from a UK warehouse in 1 to 2 days for £27.99 for 90 capsules on the first 3-month order, then £34.99 every 3 months (single bottle £24.95). Renue by Science is a US-based brand respected in the longevity research community, offering multiple NMN delivery formats (standard powder, sublingual powder, enteric-coated capsules and liposomal capsules), shipped from the US (UK customs and longer transit may apply).
