I was going to get the Jarrow Formula Methyl B12 (5000 mg) at the local health store but while at Costco I ran across the supplement aisle and I was surprised to find that now Kirkland Signature sells : B-12 Methyl (5,000 mcg) sublingual tabs (300 count). That's almost a years supply.

I know Jarrow is a very reputable brand but this Kirkland brand states that it is "USP Verified" for potency and ingredients.

Has anyone tried the Kirkland brand and would they be on-par with the quality & potency of Jarrow?

Wow... Thanks for this new information. Previously they only had Cyanocobalamin form! This is wonderful news for us, since hubby and I both take it.

All of Kirkland's products seem very good. Consumer reports, magazine, rated their Centrum Senior generic highest in its category for quality and price.

We are going tomorrow, so I'll pick up some there. (only 30 left to go until our next Puritan's order was due).

Thanks for sharing that here for us! That makes 2 wonderful new products in local stores this week, (Morton's Epsom Lotion too at WalMart!)

You're welcome!

I tried the Kirkland B12 and it was actually good tasting. I let the tablet dissolve under my tongue and it took about 40-50 seconds and it was gone, I washed it down with water afterwards.

The price can't be beat. It comes out to .06 cents per tablet. 5,000mg of methyl B12 is the good and potent kind.

Yes, this is very good for us.

But it is also a very good sign that
demand for this is increasing. It means that more and more people are learning about this, and perhaps some doctors are
joining in finally.

The same thing happened for the Kefir we use. Costco started carrying that too.

And I agree, it is a very good price. I can recall when iherb was just about the only source online for it too.

Not all B12 are created equal.

I have no idea about this specific B12 you mention but I do know tests have been done on effectiveness of B12 and some are at the bottom of the list while others, like jarrow, at the top.

Tests have to be done continuous to keep on top of it but I know if I am going to spend money, I would just as well spend a little more if it means better absorbtion/quality.

Even jarrow wont stay at the top of the list , always new and better product coming out.

But quality is important. So many supplments out there that just come out the other end with no value to our body.

There is a patent on making methyl B12.... so I would suspect
most of the raw material is from one source (or very few). This is common in the supplement industry. At one time a high % of all our vitamins came originally from Roche... who made them in Europe.
But that has changed, by now I would think.

Kirkland has an excellent quality control, so I don't expect any
problems with it. In fact hubby just called from Costco, as he did find it there this morning. We are just about out of our Puritan's here.

I did test out Puritan's when they began to offer it 2 yrs ago. I tested at 1999 after 3 months. My doctor insisted that oral would not work, and she was stunned at my test results.

Take all methylB12 on an empty stomach. I chew them up and follow with water first thing in the morning.

I called and was directed to the USP website which states:

Products that meet the program's stringent criteria are awarded the distinctive USP Verified Mark for use on labels, packaging, and promotional materials. The Mark makes it easy for customers, healthcare practitioners, and retailers to identify USP Verified products. Seeing the USP Verified Mark on a label indicates that the dietary supplement product inside:

Contains the ingredients listed on the label, in the declared potency and amounts.
Does not contain harmful levels of specified contaminants.
Will break down and release into the body within a specified amount of time.
Has been made according to FDA current Good Manufacturing Practices using sanitary and well-controlled procedures.

USP conducts a rigorous process of tests and reviews before awarding the USP Verified Mark to a dietary supplement that a manufacturer voluntarily submits for verification. The process includes the following steps:

Experienced USP scientists test supplement products to ensure that they meet USP standards for quality, purity, and potency. This includes testing dietary supplement products and their ingredients against dietary supplement standards found in The United States Pharmacopeia and The National Formulary (USP–NF).
USP conducts a thorough manufacturing and quality control/product document review.
USP performs an on-site manufacturing facility audit for compliance with USP standards and FDA current Good Manufacturing Practices (21 CFR Part 111).
After a product is verified, USP performs random, off-the-shelf testing to confirm that it continues to meet USP's strict standards.


Now with all that being said. I am confident that the Kirkland B12 Methyl is pure and potent.

The above is the link for the info.

Do you have the link for that? I'd appreciate it if you posted it here. You can edit your post within 24 hrs. It would be best to put it in there if you can. Otherwise just make a new post with the link.

Thanks so much for doing that and helping here.
