Jarrow Formulas Extra Strength Methyl B-12 1000 mcg - Dietary Supplement - 100 Lemon Flavored Chewable Tablets - Bioactive Vitamin B-12 - Supports Cellular Energy Production, Sleep & Brain Health

My doctor told me to start taking b12 because it was low and I decided to try this one. It’s affordable and tastes good and it works! My b12 in November 2020 was 246 and it went up to 559 in January 2021 while I was taking these pills

I started taking B-12 shortly after going vegan 6 months ago. I don’t think I’ve ever been B-12 deficient and likely havent been vegan long enough to tell. I don’t feel any different after taking these so I can’t vouch for their absorbency. But I know that as a vegan, it is a supplement I need to take. I first bought these in the tropical flavor which I liked a lot. When I ran out, I purchased the lemon ones because they are more economical but much much much prefer the tropical flavor. When this one runs out, I’ll repurchase tropical.

1000 mg made me jittery after a few days. I cut it d own to once every 3 days and now I can tolerate it. I can tell you this works and it works WELL. My MD told me to only buy Jarrow Methyl B-12, I dont know why. But it works very fast and will zing you out, so watch for it and reduce dose if needed.

I wanted to really like this product as it has high reviews and was referred by a Facebook for low b12 levels. I took one 1,000mg every other day, too strong. Cut it down to 250mg everyday then every other day and still too strong. It gave me heart palpitations even days after I stopped taking them. Couldn’t sleep easily either. I already have good energy with my vitamin d and magnesium so the energy this gave was too much. Gave me the sensation like I drank several energy drinks. It’s been days and still haven’t fully gotten rid of the sensation on my chest.

And oddly enough, I sleep better on the days I remember to supplement with this product. I tend to have nights of insomnia, but noticed that it never seems to happen when I take this particular B. I also take another B supplement that has other types of B12 in it, but that also has a lot of other things that tend to keep me awake if I take it too late in the day. I like having B12 I can take when I forget the other. I had pernicious anemia so seriously 11 years ago I was on daily injections for almost a year. Must take a sublingual. Also, my daughter and husband who both have celiac disease MUST supplement with B12 and it makes a difference in their energy levels. B12 is absorbed in the area of the small intestine that is destroyed by gluten, so anyone with celiac disease must take the various forms of 12 (there are four--this is the most absorbable and most important one to take if you chose just one--most companies use the cheapest one in formulas but its not very absorbable, especially in the gut-- I cant remember the exact name--). Update: I just posted this but then read the other reviews. A comment on those who say it does not dissolve well: Drink a glass of water PRIOR to taking the pill. Also, move your jaw in a chewing motion to activate the salivary glands for better absorption. This is good to do when drinking a chia drink, juicing, or whenever taking a sublingual.

For two years I suffered horrible esophageal spasms and indigestion, daily, that would go on for hours. I tried everything I could think of and nothing worked. (antacids, etc.) Then one of my friends sent me an article that said one of the symptoms of a B-12 deficiency is digestive problems. A B-12 deficiency seemed a likely possibility since I have had my gallbladder removed and am taking omeprazole. After I had my gallbladder out the indigestion began and eventually got so bad the esophageal spasms started up. Horrible. It would radiate from my stomach up my chest and into my lower jaw, over and over for hours on end. I spent many nights fighting nausea and standing over a sink drooling heavily. I had no idea such misery was possible until it happened to me. I didnt hold much hope that this would work, because nothing else did, but I figured Id try it and if it didnt work Id only be out a few dollars. Within days I was about 80% better. It gets a little better every day. My doctor poo-poohs this but my take on it is: after two years of sheer torture/agony it worked. I dont understand how it worked or why it worked only that it did--and that is good enough for me.

I read in a mindset book that our brains are coated with some white-fluid-stuff (sorry I cant remember the technical term). Anyway, when Einstein died and scientists looked at his brain, it was dripping with this white-fluid-stuff (the more to make synaptic connections?). This white-fluid-stuff in our brains thrive on Methyl B-12. After reading the book, I have taken Methyl B-12 ever since. This brand is chewable and tastes good.

The benefits from this vitamin is difficult to maintain in seniors. I read that sublingual tablets were the way to go, taking them like you would any supplement or medicine that you chew. I can not say enough about the benefits of this sublingual tablet. My 80+ year old husband no longer sleeps away his day in a recliner. I do also give him additional (2) drinkable tablets. I began these subliqual tablets along with the supplemental and my lab test measured B12 off the charts. So I cut back on the other tablets, actually to 1/2 a day. I guess I have to find out how to take just the sublingual.

These are 1000 mcg pills. These are Lozenges which means that they can be chewed or dissolved in the mouth. I felt they are little too big for me to keep under the tongue, so I keep it in the mouth and it gets dissolved just fine. These have a lemon flavour, which is sweet and not bitter. I did not feel any after-effects or discomfort from the tablets. VITAMIN B12 DEFICIENCY Vitamin B12 is important for functioning of brain and nervous system. It plays vital roles in fat and protein metabolism, hemoglobin and red blood cell production, DNA synthesis and nerve maintenance and repair. Some of the symptoms of vitamin B12 deficiency include fatigue, lethargy, depression, poor memory, breathlessness, headaches, and pale skin. If ignored for too long, Vitamin B12 deficiency can cause severe and permanent damage. Since Vitamin B12 effects the brain function it can also effect the mood and low levels of vitamin B12 is also linked to depression and paranoia. DOSAGE Recommended Dietary allowance for Vitamin B12 varies with age, whether person is pregnant, or nursing, if there is a condition that needs to be treated or if a person is healthy. Usually for healthy adults the dosage is considered to be 2.4-4.0 mcg per day irrespective of which type of B12 (cobalamin) is being taken. However, for people having vitamin B-12 deficiency the doctor may prescribe higher doses. Since Vitamin B12 is water soluble, so excess Vitamin B12 is removed by the body (and doses upto 500-1000 mcg wont cause side-effects). There are no Upper intake levels suggested, however, if a person ends up in taking extremely high amounts of B-12 body will start using more water to purge the excess B12 out of body and may start showing the symptoms of overdose such as flushing of the skin, increased thirst, excessive urination and diarrhea. ARE THESE PILLS VEGAN The information on the bottle says that these are vegan and does not contain wheat, glutten, soybeans, dairy, egg, fish/shellfish, peanuts/tree nuts. Usually Vitamin B-12 is synthesized by bacteria found in animals, so B-12 is found in sources such as seafood, beef, poultry, eggs and milk or other dairy products. For people following strictly vegetarian diet, they might have Vitamin b12 deficiency and these pills seems to be a good fit for them. Also, while reading up on these pills I came across some interesting information on several web-sites about these vitamins and why are they named so. WHY IS VITAMIN B NAMED SO Vitamin B has an interesting history. In the 19th and early 20th century scientists were looking into a disease called beriberi (whose symptoms included weakness and loss of feeling in the feet and legs, edema of the trunk, difficulty in breathing etc.) Several researchers had observed that this disease was related to rice diet. It wasnt until Adolphe Vorderman (a medical inspector for prison) noticed that prisoners who had a diet of mostly brown rice had significantly less cases of beriberi than the prisoners who had diet of mostly white rice. After this several scientists were trying to separate the compound in brown rice that was responsible for preventing beriberi. A polish scientist named Casimir Funk claimed to have separated that compound and named it vitamine by combining vital amines (because it contained an amino group.) Though it was realized later that he was not completely successful in isolating the active compound from rice.It was American biochemist Elmer McCollum who was successful in doing that. Since they did not understood the complete chemical composition of the compound yet, so compound was give a generic name factor B. He had also named another compound he had discovered as factor A. However, scientific community needed a batter names than water soluble factor B (or fat-soluble factor A) so they adapted Funks nomenclature and naming them as Vitamin A, Vitamin B. The e at the end of vitamine was removed because not all compound contained animo groups and one of the rules of nomenclature mentioned naming a neutral substance of undefined composition ending in in. So the name Vitamin was adopted by scientific community and most of the new compounds were named similarly e.g. Vitamin C, Vitamin D until their complete chemical composition could be determined (some exception exists such as Vitamin K which was derived from German word Koagulation (coagulation) since this compound was a prerequisite for blood coagulation) Though even after determining the complete chemical composition of Vitamins, we still call them as Vitamin because it is easier to remember them instead of the chemical term. WHY IS VITAMIN B12 NAMED SO After further research it was found that what was earlier thought to be single vitamin was in-fact chemically distinct compounds that occurred in the food together. All these compounds were given numbers e.g. Vitamin B9 is folic acid. Vitamin B12 is a compound that contains the essential mineral cobalt. There were several Vitamin B discovered, however it was late found that only few of the Vitamin Bs are actual vital: Vitamin B1, B2, B3, B5, B6, B7, B9, and B12. Supplements that contain all these are sold as Vitamin B complex. WHAT IS METHYL B12 Vitamin B12 is also called cobalamin, which refers to compound that have cobal ion in the middle. Depending upon to which component cobalt is attached to it is named differently (Cyanocobalamin, Hydroxocobalamin, Adenosylcobalamin, and Methylcobalamin) Methylcobalamin contains cobalt joined with Methyl IS METHYL B12 SPECIAL The bottle mentions that Methyl B12 is superior form of B12. I am not sure of if the body gets more benefits from this form of B12, but Adenosylcobalamin, and Methylcobalamin are the forms of B12 that naturally occur in the body. So the body doesnt have to covert this form of vitamin B12 and can be absorbed easily.

I took the first lemon flavored 500 mcg tablet today. It only took about 15 minutes to melt under my tongue. I have high hopes for this product... Hopefully it will work for me. The size of the tablet was not bad, a little larger than a pencil eraser. From some of the other reviews I thought it was going to be huge. Its not. I am giving it a 5 to start out, because of the size of the tablet, ease in melting, and packaging. I will update after I have taken it longer. I am looking forward to having more energy, sleeping better and building stronger bones! I am 68 and I am feeling my age. I am hoping this product helps me get some energy back.
