FAQs
How many capsules are in one jar of Vitals Vitamin B12 1000 µg?
One jar contains 100 vegetarian capsules.
How long will one jar last with daily use?
100 days when taking 1 capsule per day, or 50 days when taking 2 capsules per day, in accordance with the recommended dosage on the label.
What is the difference between methylcobalamin and adenosylcobalamin?
Methylcobalamin and adenosylcobalamin are the two biologically active coenzyme forms of vitamin B12. Methylcobalamin is active in blood plasma and cytoplasm; adenosylcobalamin (dibencozide) is active in the mitochondria of tissues. Together, they cover the two main roles of vitamin B12 in the body.
Why not cyanocobalamin?
Cyanocobalamin is a synthetic form that the body must first convert into the active coenzyme forms before it can be used. By directly supplying methyl- and adenosylcobalamin, this conversion step is bypassed.
Can I open the capsule and sprinkle the powder under my tongue?
Yes — the capsule can be opened and the powder can be taken sublingually (under the tongue). Taking the whole capsule with water is equally effective and not strictly necessary.
Is this product suitable for vegans?
Yes — Vitals Vitamin B12 1000 µg is 100% vegan. The plant-based pullulan capsule is derived from fermented starch.
Does this product contain allergens?
No — no allergens are listed on the label.
Can I use B12 long-term?
Yes, vitamin B12 is water-soluble and suitable for long-term use at this dosage; an excess is largely excreted through urine. With long-term high use, periodic evaluation of B12 status is advisable.
Can I combine this product with other supplements?
Yes — Vitals Vitamin B12 1000 µg combines well with a complete B-complex or a multi containing folate and B6. If taking medication (e.g. anticoagulants, metformin, or antacids): consult a doctor or pharmacist beforehand.
