Pure Encapsulations Methylcobalamin 1,000 mcg - 180 Capsules Review
8.6/10SAC Product Score™
You're buying allergen-purity, not more B12. Pure Encapsulations is a physician-channel brand built around obsessive 'free-from' formulations, and this is the same active methylcobalamin at the same sensible 1,000 mcg dose you'll find far cheaper — with a hypoallergenic build made for people who react to everything. For someone with multiple sensitivities, that's worth real money. For everyone else, the premium doesn't buy efficacy.

Form & Bioavailability20%9.2/10
Active methylcobalamin in a vegetarian capsule — bioavailability is identical to the cheaper methyl picks. The form is a real plus for the methylation-impaired minority, neutral for everyone else.
Dose vs Clinical Range20%9.5/10
1,000 mcg is the sensible oral repletion dose, matching what the evidence supports for correcting deficiency.
Third-Party Testing & Purity25%8.3/10
Made in a GMP facility with a hypoallergenic, non-GMO, gluten-free 'free-from' formulation that's a genuine purity edge for sensitive users. It loses points for carrying no independent USP or NSF seal despite premium positioning.
Value Per Serving15%6.5/10
At ~$0.23/serving the cost per capsule matches Thorne, but the bottle runs roughly 2-3x the price of an identical methyl product. You pay a real premium for the allergen-free formulation, not for more B12.
GI Tolerance & Format Suitability20%9.3/10
This is where it earns its keep — a deliberately hypoallergenic vegetarian capsule engineered to be tolerated by people who react to fillers, dyes, and common allergens.

Marketing claims vs. reality
False
“The premium price buys more or better B12”
It's the same 1,000 mcg methylcobalamin available for roughly a third of the price; the premium buys allergen-purity, not efficacy or a higher-quality active.
Partial
“Physician-grade quality”
It's a physician-channel brand made under GMP, but it carries no independent USP or NSF seal despite the premium positioning.
Verified
“1,000 mcg corrects deficiency”
The sensible oral repletion dose normalizes B12 status in most people (Stabler 2013; Wang Cochrane 2018).
What our test actually found
01You're paying for what's left out
The value here is the absence of allergens and fillers, not any extra B12. That's a real product for the right buyer and a waste for everyone else.
02Identical active, triple the price
The 1,000 mcg methylcobalamin is the same molecule as a $16 bottle. If you have no sensitivities, the premium buys you nothing.
03Premium positioning, no premium seal
For the price you might expect USP or NSF verification; you don't get it. You're trusting the brand's GMP reputation instead.
04Genuinely the sensitive-stomach pick
For people who react to dyes, fillers, or common allergens, the hypoallergenic build is worth seeking out — that's exactly who this is for.
Pros & cons, no sugar-coating
Pros
- Hypoallergenic 'free-from' formula built for sensitive users
- Physician-channel brand made in a GMP facility
- Sensible 1,000 mcg repletion dose
- 180-count is a ~6-month supply
Cons
- Roughly 2-3x the price of an identical methyl bottle
- No USP or NSF seal despite the premium positioning
- The premium buys allergen-purity, not more or better B12
Allergen-purity, not efficacy
You're buying allergen-purity, not more B12. For someone with multiple sensitivities — or a physician who insists on the Pure brand — the hypoallergenic formulation is worth something real. For everyone else, it's the same 1,000 mcg methylcobalamin available for a third of the price; the premium doesn't buy efficacy.
