Nusava B12 Liquid Drops Review 2026: Legit or Overhyped?
Read before you buy. — Overhyped
-
"Maximum Strength, potent bioavailable B12 formula"
The page lists no mg or mcg dose anywhere, so the 'maximum strength' claim can't be checked.
-
"Boosts energy and mental clarity"
B12 only raises energy or clarity in people who are actually deficient, per Examine.com's review of the evidence.
Examine.com vitamin B12 overview -
"Sublingual drops absorb better"
A controlled trial found sublingual B12 absorbs about the same as swallowing it, not meaningfully better.
PubMed: Sharabi et al. 2003 -
"Save 53% off $239.96"
The 'regular price' used for the discount math is set by the seller, not an independent market price, so the savings figure is likely exaggerated.
Consumer advice
If you have a confirmed B12 or B-vitamin deficiency (common in vegans, older adults, or people on metformin), this type of liquid B-complex can help, but check the Supplement Facts panel on the actual bottle for mcg/mg amounts before buying - don't rely on marketing copy. Compare the per-dose price to a basic drugstore B12 liquid first; B vitamins are cheap commodity ingredients and you're likely paying a large markup for flavoring and bundling psychology. Ignore the "regular price" anchor - that $239.96 "regular" figure for 4 bottles looks inflated specifically to make the $112 sale price seem like a bigger deal than it is.
