Nutricology B12 Adenosylcobalamin 3000 mcg - Active Vitamin B12 Lozenges - Mitochondrial Energy & Nerve Support - Vegetarian - 60 Lozenges

Key Benefits of Vitamin B12

Vitamin B12 contributes to normal energy-yielding metabolism, normal nervous system function, normal homocysteine metabolism, normal psychological function, and normal red blood cell formation. These EFSA-authorised claims highlight the importance of maintaining adequate B12 levels for overall wellbeing. Our Nutricology B12 Adenosylcobalamin lozenges provide 3000 mcg of the active coenzyme form, directly supporting these essential processes.*

• Energy Production: B12 helps convert food into glucose, which the body uses for energy. By supporting mitochondrial energy metabolism, it aids in reducing fatigue and promoting vitality.*
• Nerve Health: B12 is vital for maintaining the myelin sheath that protects nerve fibres, thereby supporting normal nervous system function.*
• Brain Support: This vitamin supports cognitive function, including memory and concentration, by aiding neurotransmitter synthesis.*
• Red Blood Cell Formation: B12 is necessary for the production of healthy red blood cells, which transport oxygen throughout the body.*
• Heart Health: Along with other B vitamins, B12 helps regulate homocysteine levels, an amino acid linked to cardiovascular health.*

These benefits are backed by decades of research, making B12 a cornerstone of daily wellness regimens.

Who Should Take a Vitamin B12 Supplement?

Certain groups are at higher risk for low B12 levels. Vegans and vegetarians often lack dietary sources of B12, as it is not naturally present in plant foods. Older adults may experience reduced stomach acid production, which impairs B12 absorption from food. Individuals with digestive conditions like Crohn’s disease or those who have undergone gastric surgery may also struggle to absorb B12 effectively. Additionally, people taking certain medications such as metformin or proton pump inhibitors may benefit from supplementation.

Even if you do not fall into these categories, maintaining optimal B12 levels supports overall wellness, especially energy and cognitive function. This supplement is suitable for anyone looking to fill dietary gaps or support healthy nerve function.*

How to Choose the Best B12 Supplement

Not all B12 supplements are created equal. The form of B12 matters significantly for absorption and efficacy. Nutricology B12 Adenosylcobalamin contains the active coenzyme form that is directly usable by the body, particularly by the mitochondria—the energy powerhouses of your cells. This is distinct from cyanocobalamin, a synthetic form that must be converted in the body before it can be utilised.

Dosage is also key. With 3000 mcg per lozenge, this supplement provides a high-dose option that ensures saturating levels, especially beneficial for those with absorption challenges. The lozenge delivery allows for sublingual absorption, bypassing the digestive system for potentially better uptake. Additionally, this product is made without common allergens: it is free from gluten, dairy, soya, nuts, eggs, shellfish, fish, and sesame, making it suitable for individuals with sensitivities.

When choosing a B12 supplement, look for a trusted brand with a history of quality. Allergy Research Group has been a leader in the supplement industry for over 45 years, backed by science and a commitment to purity.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is an essential water-soluble vitamin that plays a critical role in red blood cell formation, DNA synthesis, and neurological function. Unlike many other vitamins, B12 is naturally found almost exclusively in animal products, making supplementation important for those following plant-based diets. The body requires B12 to convert food into usable energy—specifically, it supports the metabolism of every cell in your body. Without adequate B12, you may experience fatigue, weakness, and other health concerns.

Nutricology B12 Adenosylcobalamin delivers 3000 mcg of the active coenzyme form of vitamin B12 in a convenient lozenge. This high-potency formula is designed to support mitochondrial function and overall vitality.*

Recommended Dosage and How to Take B12

Take one lozenge daily. Place it in your mouth and allow it to dissolve slowly—preferably under the tongue for optimal absorption. The 3000 mcg dose is well above the daily recommended intake, but because B12 is water-soluble and excess is excreted in urine, it is generally considered safe even at high doses. However, it is always wise to consult with a health care professional before starting any new supplement, especially if you have a medical condition or are pregnant or nursing.

Frequently Asked Questions

Can you take too much B12?

Vitamin B12 is water-soluble, meaning your body flushes out any excess through urine. High doses up to 5000 mcg per day are generally considered safe. However, if you have specific health concerns, speak with your doctor.

What is the difference between adenosylcobalamin and methylcobalamin?

Adenosylcobalamin and methylcobalamin are both active coenzyme forms of B12. Adenosylcobalamin is primarily involved in mitochondrial energy production, while methylcobalamin supports methylation processes and nerve health. Some supplements combine both, but for targeted mitochondrial support, adenosylcobalamin is ideal.

Why choose a lozenge over capsules?

Lozenges dissolve in the mouth and can be absorbed sublingually, bypassing the digestive tract. This may benefit individuals with poor stomach absorption due to age or digestive conditions.
