Rated 5 out of 5 by Great value I love this product. Works great for me. Gives me a nice boost when needed. November 3, 2015
Rated 5 out of 5 by Great product! This product is very effective! Fast acting! I would recommend this to any who need B12. I noticed a difference in my mood in a matter of days. Very thankful. December 27, 2014
Rated 5 out of 5 by great product This is a very convenient and highly concentrated form of B12. We use it daily, cannot comment on the bursts of energy felt by many other reviewers, we haven't noticed any increase in energy. It is easy to use, dissolves well in matter of minutes under the tongue. Taste is pleasant. We will have our levels rechecked and will see. July 13, 2014
Rated 5 out of 5 by Gives me Extra Energy I'm a 62 year old guy that likes working out with weights. I have tried many other brands of b12 that were so so, but 21st Century's really gave me the boost I had been looking for. Take one under the tongue 25-30 minutes before exertion. It gives you a little get up and go May 4, 2014
Rated 5 out of 5 by Great deal Best price for a quality sublingual version of B-12. Bought several brands in the past - Rexall, Kroger, Walmart yet this is the best price for the quantity & strength I have found. January 13, 2014
Rated 5 out of 5 by great for extra energy helps with extra energy without any gitters December 10, 2013
Rated 3 out of 5 by Waiting to See Always buy the methlycobalamin micrlozenges form of B12. This was such an excellent price thought I would simply give this Cyanocobalalamin form a chance to work as I liked the price for number of lozenges and the 5000 mcg. Will have to try it and compare to what I normally order. B12 has done wonders for me at age 67. Think everyone over 50 should take it. December 9, 2013
Rated 5 out of 5 by Does great job - for great price I have sensed much more energy taking the 5,000 mg tablets than lesser amounts before discovering this potency of tablet. The price is great, also! I highly recommend it! November 9, 2013
Rated 5 out of 5 by Great Product This is a great energy booster. I take two first thing in the morning and two at noon. It helps me get through the day. October 28, 2013
Rated 5 out of 5 by Used by all family members. I have used this Vitamin B-12 for the past 2 years and find it very easy to take. let it melt in your mouth and it has a very nice taste. September 23, 2013
Rated 4 out of 5 by Just OK This product is a bit chalking and doesn't dissolve all the way through. The taste is alright and the price is good but quality is lacking. September 20, 2013
Rated 5 out of 5 by Way to start the day This is one thing I don't want to run out of. Me and my husband take one every morning. We're very busy people, up too early, go to bed too late. I'm allergic to caffeine so I need some help to get going in the morning. Love em' August 31, 2013
Rated 5 out of 5 by Great Product This product helps with my overall energy level and, therefore, helps me stay with my new diet and exercise life. Fantastic energy when I'm 64. I feel 34!. Thanks Swansons August 29, 2013

Rated 5 out of 5 by B-12 should be taken sublingually and this is a great product for that purpose. It dissolves nicely and tastes good. Not to mention that it gives a little energy boost and helps with sleep interruption. May 30, 2013
Rated 5 out of 5 by Hi-potency B12 sublingual Excellent results according to blood work. I cannot absorb via gastric tract, dissolves immediately under tongue. Definitely recommend! May 16, 2013
Rated 5 out of 5 by Sublingual vitamin B-12 I have used this product for awhile and it couldn't be easier to take. It's the first thing I do every morning. I am not a coffee drinker and this really wakes me up and gives me the energy to get through my day. May 12, 2013

Rated 5 out of 5 by B-12 Keeps Me Moving For me B-12 seems essential, just seems to keep me going during the day. March 30, 2013
Rated 5 out of 5 by I like the sweet cherry taste and the energy! Definitely very convenient and I enjoy the taste. It takes a few minutes to dissolve under your tongue, but who cares! It works! High concentration is also nice, to ensure absorption of a good dose. Price is also great. If I sleep 4 or 5 hours, I pop one pill and feel remarkably recovered and ready to start the day. Will buy this again! January 28, 2013
