Natural Factors - B12 Methylcobalamin (5000mcg) - 60 chewables

High-Potency B12 in the Most Bioactive Form

Natural Factors B12 Methylcobalamin delivers 5,000 mcg of methylcobalamin—the active, coenzyme form of vitamin B12 that's immediately ready for your body to use. Unlike cyanocobalamin (the synthetic form found in many supplements), methylcobalamin doesn't require conversion and is better retained in tissues, making it the superior choice for supporting energy production, nervous system health, cognitive function, and red blood cell formation. These delicious cherry-flavored chewable tablets dissolve quickly for fast absorption.

Why Methylcobalamin?

Vitamin B12 exists in several forms, but methylcobalamin is the active coenzyme form that your body uses directly—no conversion required. This makes it more bioavailable and better retained in your liver, brain, and nervous system compared to cyanocobalamin, the synthetic form commonly found in supplements and fortified foods. Methylcobalamin is particularly important for neurological health because it's the primary form of B12 stored in the central nervous system and plays a direct role in myelin synthesis and nerve regeneration.

Who Needs B12?

Vitamin B12 deficiency is surprisingly common, affecting up to 15% of the general population and even higher percentages among certain groups. You may be at increased risk if you're over 50 (stomach acid production decreases with age), follow a vegetarian or vegan diet (B12 is found primarily in animal products), take certain medications (including metformin and proton pump inhibitors), or have digestive conditions that impair nutrient absorption. Even mild B12 deficiency can cause fatigue, weakness, memory problems, and mood changes.

Who It's For

B12 Methylcobalamin is ideal for adults seeking to boost energy levels, support cognitive function and memory, maintain nervous system health, or address B12 deficiency. It's particularly beneficial for vegetarians and vegans, older adults, those taking medications that deplete B12, individuals with digestive issues, or anyone experiencing fatigue, brain fog, or low mood.

Suggested Use

Chew 1 tablet daily or as directed by a healthcare practitioner. For best absorption, allow tablet to dissolve completely in the mouth before swallowing. Can be taken with or without food.
