Jarrow Methyl B12 500mcg
Verified purchase
I really like the taste of the Jarrow B12s. This fruit flavor is good, but I prefer the lemon. This isn't a thin chewable, it's more a small round tablet. I think the quality of these are good. This one is a lower dose than I would normally use.

Great
Verified purchase
Great if you need a high dose of methylated B12. I only need about half as much per dose so I cut them in half.

take 1st thing in the morning
Verified purchase
A good product to take 1st thing in the morning, on an empty stomach. Perfect for me to supports nerve regeneration (i have neuropathy), brain function (common for women like me who's post menopausal and gets brain fog), and energy production (i feel energized and strong to do my morning walk)

No complaints!

Good quality and the taste is just fine. They're a little pricey but as a vegan I want to make sure I'm covering my bases. Well packaged and gets the job done!

Methyl B-12, Cherry , 500 mcg
Verified purchase
I’ve been taking Methyl B-12, Cherry, 500 mcg for several weeks, and it’s become a convenient and effective part of my daily routine. This supplement provides methylcobalamin, the active and highly bioavailable form of B12, which supports energy production, nervous system health, and cognitive function. Since starting it, I’ve noticed increased mental clarity, sustained energy, and reduced fatigue, making it easier to get through busy days.

Great quality and taste
Verified purchase
I think Jarrow makes high-quality supplements, and I've been using their B-12 for quite a while. It has a sweetness that tastes natural, and it has a nice texture. It is also great that their is a variety of choices, from lower to higher potency. To sum up: Great taste, great ingredients, great quality. Highly recommended.

Excellent B-12 Supplement in a Tasty Chewable Form
Verified purchase
’ve been taking Jarrow Formulas Methyl B-12 for a while now, and I’m really impressed with the quality. The cherry flavor is pleasant, slightly sweet but not overly sugary, which makes it easy to take daily without feeling like medicine. The chewable tablets dissolve well and don’t leave any chalky aftertaste. this is the methylated form of B-12 (methylcobalamin), which is known to be better absorbed and more bioavailable compared to the standard cyanocobalamin form. I’ve noticed a real difference in my energy levels, mental clarity, and overall mood since incorporating it into my routine. If you’re looking for a reliable B-12 supplement that’s easy to take and actually enjoyable, I highly recommend this one from Jarrow Formulas.

This is the perfect form of Vitamin B-12 for anyone who can't handle the taste or smell of B-12 tablets. Jarrrow's Methyl B-12 chewable tablets are very pleasant tasting, easy to chew, and I've found no negative effects from taking them. This item comes in a small bottle so you may want to get two ... just incase. Highly recommend.
