It's the cheapest route to adenosylcobalamin, which is the draw. The catch is the added synthetic folic acid — a real drawback for anyone specifically avoiding folic acid or managing MTHFR concerns, and it takes the clean single-ingredient option off the table. If you want adenosyl B12 without the folic acid, Seeking Health is the cleaner (pricier) choice.

Read the complete Vitamin B12 guide →Adenosylcobalamin (dibencozide) is a valid active coenzyme form, but the added synthetic folic acid removes the clean single-ingredient option and is a drawback for many buyers — pulling the form score below the pure adenosyl pick.
3,000 mcg B12 is above true repletion need, and the added folic acid means you're taking a second nutrient you may not want alongside it.
Certified gluten-free and non-GMO per label, but no independent USP or NSF seal — the weakest testing credentials in the set.
At about $0.28/serving it's the cheapest entry into the adenosyl form — its main selling point — though not cheap in absolute terms for a 60-count.
A sublingual lozenge held under the tongue, easy for pill-averse users, though the added folic acid means it's no longer a clean single-nutrient product.
“The added folic acid is a benefit”
Folate does pair with B12 in homocysteine metabolism, but the synthetic folic acid form is a drawback for anyone avoiding folic acid or managing MTHFR concerns, and it removes the clean single-ingredient option.
“Adenosyl form boosts energy”
The adenosyl form is mechanistically tied to mitochondrial energy, but clinical evidence it out-performs cheaper forms for energy is thin (Paul & Brady 2017; Tardy 2020).
“3,000 mcg is needed for repletion”
It's above true repletion need; around 1,000 mcg already corrects a deficiency, and the excess is largely excreted (Stabler 2013).
“Cheapest entry into the adenosyl form”
At about $0.28/serving it's the lowest-cost adenosylcobalamin option in this set.
It's the lowest-cost way into the dibencozide form — but the added folic acid is the string that keeps it from being a clean pick.
Synthetic folic acid is a genuine drawback for anyone avoiding it or managing MTHFR concerns, and it takes the single-ingredient option off the table.
At 3,000 mcg B12 it exceeds true repletion need; most of the excess is simply excreted.
If you want adenosyl B12 without folic acid, Seeking Health's methyl-free lozenge is the cleaner, if pricier, choice.

See it on the list →Adenosylcobalamin is a valid active form, but evidence that it out-performs cheaper forms for general repletion or energy is limited.
Around 1,000 mcg of oral cobalamin corrects deficiency; higher doses like 3,000 mcg are largely excreted.
B12 and folate support energy metabolism, but supplementation boosts energy only when it corrects an underlying deficiency.
