NOW Foods sells chewable Vitamin B12 lozenges across multiple listings and formulations — the brand’s own product pages describe a 1,000 mcg chewable lozenge aimed at maintaining nervous system health and energy production, while some retailers list a 2,000 mcg, 100‑lozenge option. The lozenges are presented as vegetarian/vegan‑friendly and flavored (strawberry/fruit punch on some Canadian listings), packaged for daily sublingual/chewable dosing rather than injections.
This review synthesizes customer feedback from an iHerb listing and user comments, NOW Foods product pages (U.S. and Canada), an Amazon product listing, aggregated user reviews on WebMD, and a Verywell Health article summarizing rare B12 side effects. I focused on reported effects, formulation details visible on product pages, and recurring complaints such as moisture sensitivity and isolated adverse reactions.
High level: NOW B12 lozenges reliably deliver high nominal doses (commonly 1,000 mcg, with a 2,000 mcg retail variant) and are widely reported to increase energy and support nervous‑system symptoms for many users; they’re small, pleasant‑tasting, and chewable. The main drawbacks are packaging/stability in humid conditions (users report lozenges absorbing moisture and clumping) and the small but real chance of uncommon side effects (allergic reactions, skin flare‑ups, and in high‑dose therapeutic contexts, possible low potassium).
Does it actually support energy and nerves?
Multiple customer reports (iHerb and WebMD user comments) note a noticeable increase in energy and improvements in nervous‑system complaints after taking NOW B12 lozenges; NOW’s product descriptions also list energy production and nervous system maintenance as intended benefits. The product is offered in 1,000 mcg lozenges on NOW’s site and a 2,000 mcg, 100‑lozenge SKU appears on some retailer pages, so daily dosing can be adjusted by dose and frequency.
That said, individual response varies: WebMD user reports include both strong benefit and cases where users saw no improvement or experienced adverse effects. People with documented malabsorption (who require injections) were reported to use injections rather than oral lozenges, indicating lozenges are most useful for users with adequate absorption.
Are the lozenges pleasant and easy to use?
Customer feedback highlights pleasant flavor, small size, and easy chewability — descriptors found repeatedly on retailer pages. NOW’s product pages list fruit‑flavored chewables and position them as easy daily supplements for vegetarians/vegans, which matches the reported user experience of straightforward oral dosing.
Because they’re chewable/lozenges rather than tablets or injections, they’re convenient for people who prefer not to swallow pills; the 100‑lozenge count on some retailer listings provides roughly three months’ supply at a typical once‑daily dose for the 1000 mcg formulation, or less if using higher dosing schedules.
How well do they store and ship?
A recurring complaint in buyer comments is moisture sensitivity: users reported the lozenges can absorb moisture in humid environments, causing them to become sticky or clumped together. That indicates storage in a dry, cool place and attention to bottle seals are important for product integrity.
NOW’s product pages do not emphasize special humidity‑resistant packaging, so buyers in humid climates should expect to transfer lozenges to an airtight container with a desiccant packet or keep them in climate‑controlled storage to avoid clumping.
What are the known risks and interactions?
Vitamin B12 is generally safe, but sources in the brief note rare reactions like allergies or skin flare‑ups and the potential for low potassium during high‑dose treatment; WebMD user reports include isolated accounts of extreme tiredness or mood changes after taking B12 lozenges. NOW’s formulations use cyanocobalamin on at least one Canadian product page, which is a commonly used, generally well‑tolerated form.
If you take medications that affect B12 status or have an absorption disorder, consult a healthcare provider — some people with true absorption issues require intramuscular injections rather than oral supplementation. Stop and seek medical advice if you experience allergic symptoms or unexplained extreme fatigue after starting a supplement.
How does NOW B12 stack up against alternatives?
NOW provides straightforward, high‑dose cyanocobalamin lozenges that many users find effective, and the brand’s multiple listings include common strengths (1,000 mcg and a 2,000 mcg retailer variant). Competitors offer different active forms (methylcobalamin vs cyanocobalamin) and delivery choices (lozenges, fast‑dissolve tablets, sprays), so formulation choice should reflect personal preference and any clinician guidance.
The practical differences are: NOW is widely available in chewable lozenge form and suits vegetarians; alternatives may offer methylated B12 (preferred by some users) or different packaging that mitigates humidity risk. See the competitors section below for direct product alternatives.

How It Compares to the Competition
- Jarrow Formulas Methyl B-12 1,000 mcg — Offers methylcobalamin (the methylated form) rather than cyanocobalamin, preferred by some users for direct use in methylation pathways.
- Nature's Bounty B-12 Fast Dissolve 1,000 mcg — Fast‑dissolve format similar to lozenges; widely available and comparable dose options but differs by brand formulation and flavoring.
- Solgar Methylcobalamin 1,000 mcg Lozenges — Solgar provides methylcobalamin lozenges for users seeking the methylated form in a chewable delivery; packaging and flavor profiles differ from NOW.

Who Should Buy This & Who Should Skip It
Buy it if: Buy if you want a chewable, vegetarian‑friendly high‑dose B12 option (NOW lists 1,000 mcg; some retailers show a 2,000 mcg, 100‑lozenge variant), if you prefer a flavored lozenge to swallowing pills, or if you’re supplementing for general energy and nervous‑system support and have no known absorption issues.
Skip it if: Skip if you have documented B12 malabsorption or pernicious anemia and require intramuscular B12 injections, or if you live in a humid environment and cannot store supplements in a dry, airtight container. Also consult a clinician before starting high‑dose B12 if you have allergies or are on medications that affect B12 status.
