What It Is

Bulletproof Methyl B-12 is a daily vitamin B12 supplement in chewable lozenge form. Each lozenge supplies 5,000 micrograms (5mg) of methylcobalamin — one of the two biologically active forms of vitamin B12 (the other being adenosylcobalamin).

The lozenge is designed to be chewed or allowed to dissolve in the mouth. The natural cool-spearmint flavour is supplied by spearmint extract, with no artificial flavourings.

Vitamin B12 is one of the few vitamins not naturally found in plant foods in bioavailable quantities. Vegans and vegetarians often choose to include a B12 supplement in their daily routine. This product is suitable for both vegans and vegetarians.

Nutrient Information

Vitamin B12 is recognised for the following contributions:

✓Vitamin B12 – contributes to normal red blood cell formation
✓Vitamin B12 – contributes to normal nervous system function
✓Vitamin B12 – contributes to the reduction of tiredness and fatigue
✓Vitamin B12 – contributes to normal energy-yielding metabolism
✓Vitamin B12 – contributes to normal homocysteine metabolism

Methylcobalamin vs Cyanocobalamin

Vitamin B12 exists in multiple chemical forms. The two most relevant for supplementation are:

Cyanocobalamin

A synthetic form of vitamin B12 commonly used in supplements. Cyanocobalamin contains a cyanide group attached to the cobalamin molecule. It has a different chemical structure to methylcobalamin and is metabolised via different biochemical pathways.

Methylcobalamin (this product)

One of the two forms of vitamin B12 found naturally in animal foods, alongside adenosylcobalamin. It has a different chemical structure to cyanocobalamin, with a methyl group attached to the cobalamin molecule.

Why a Chewable Lozenge?

Vitamin B12 in lozenge form is designed to dissolve in the mouth rather than being swallowed whole. Some users prefer this format because it doesn’t require water and offers a different consumption experience to traditional capsules or tablets.

The lozenge can be chewed or allowed to dissolve. The natural cool-spearmint flavour is supplied by spearmint flavour, with no artificial sweeteners or colourings. The lozenge base is sweetened with mannitol, a sugar alcohol that does not contribute to dental caries and has a low glycaemic impact.

Good to Know

Why do vegans often choose B12 supplements?

Vitamin B12 is naturally found almost exclusively in animal foods (meat, fish, eggs, dairy). Plant foods do not reliably provide B12 in bioavailable quantities. Many vegans and vegetarians choose to include a B12 supplement in their daily routine for this reason.

Why such a high dose (5,000mcg)?

Vitamin B12 has a unique absorption mechanism. The intrinsic-factor pathway (the body’s primary B12 absorption mechanism) has a limited capacity per dose. Higher-dose B12 supplements are common in the market because B12 has a wide safety margin — no upper intake limit has been established by major regulatory bodies, since excess B12 is excreted in urine rather than accumulating in the body.

Should I take it with food or on an empty stomach?

Either is fine. Many users take it first thing in the morning for convenience, but timing is flexible — consistency at the same time each day is more important than the specific time chosen.

What is mannitol?

Mannitol is a naturally-occurring sugar alcohol found in many fruits and vegetables (small amounts naturally occur in pumpkins, celery, olives and seaweeds). It provides sweetness without contributing significantly to blood sugar and is widely used in sugar-free lozenges, chewing gums and pharmaceutical applications. Some people may experience digestive sensitivity to sugar alcohols at higher doses.

Why not just take it as a regular tablet?

Lozenge and chewable formats allow the product to dissolve in the mouth rather than being swallowed whole. Some users prefer this format because it doesn’t require water and offers a different consumption experience to traditional capsules or tablets.

Important Information

Adult use only. Always read the label and follow the directions for use. Keep out of reach of children. Contains mannitol — some people may experience digestive sensitivity to sugar alcohols.

If pregnant, breastfeeding, taking prescription medication, or have any medical condition, consult a qualified healthcare practitioner before use.
