Advanced B-12 Complex, 5 mg - 30 Lozenges

How to Take Advanced B-12 Complex

For best results, allow one lozenge to dissolve slowly in your mouth, ideally between meals. Sublingual absorption can help bypass the digestive system and deliver vitamin B12 directly into the bloodstream. Do not swallow the lozenge whole. Take one lozenge per day, or as advised by your health care professional. Since B12 is water-soluble, any excess is excreted, making it generally well tolerated. This supplement can be taken alongside other products, but consult a doctor if you are on medications such as metformin or proton pump inhibitors, which may interfere with B12 absorption.

Key Ingredients & Forms of B12

This supplement contains three specialised forms of vitamin B12: Methylcobalamin is the predominant form in the bloodstream, essential for neurological function and methylation. Adenosylcobalamin works inside mitochondria to support cellular energy metabolism. Hydroxocobalamin acts as a transport form, moving B12 through the body to tissues. Each lozenge delivers 5 mg (5,000 mcg) of total B12, a potent dose that benefits older adults, vegans, and those with digestive conditions. The combination of bioactive forms ensures maximum bioavailability.

Benefits of Advanced B-12 Complex

Vitamin B12 contributes to normal energy-yielding metabolism, helping to combat fatigue and maintain vitality. It also supports normal functioning of the nervous system and normal red blood cell formation. Additionally, B12 contributes to normal homocysteine metabolism, which is important for cardiovascular health. The lozenge format allows sublingual absorption, bypassing the digestive tract for those with absorption issues. This formula is suitable for vegetarians and free from common allergens such as gluten, dairy, soya, and eggs. It contains no preservatives or artificial colours, flavours, or fragrances.

What Makes Advanced B-12 Complex Unique?

The Advanced B-12 Complex from Source Naturals stands out because it delivers three distinct bioactive forms of vitamin B12 in one convenient lozenge. Most B12 supplements contain only cyanocobalamin, a synthetic form that requires conversion in the body. This formula provides methylcobalamin, adenosylcobalamin (also called dibencozide), and hydroxocobalamin – all of which are ready for immediate uses. Methylcobalamin and adenosylcobalamin are coenzymated, meaning they are already in the active form. Hydroxocobalamin serves as a transport form that moves through your bloodstream to tissues. Together, these three forms offer comprehensive B12 support.

How to Choose the Right B12 Supplement

When selecting a B12 supplement, consider the form used. Active forms like methylcobalamin and adenosylcobalamin are better absorbed than cyanocobalamin, especially for people with MTHFR gene variants. Dosage is another factor: 5 mg is a high-dose suitable for correcting deficiencies or supporting high energy demands. Also check for allergens and dietary preferences. This product is vegetarian and free of yeast, dairy, egg, gluten, soya, and wheat. The lozenge format offers convenience and enhanced absorption through the oral mucosa. Finally, choose a reputable brand that tests for purity and potency.

Frequently Asked Questions

What is the difference between methylcobalamin and cyanocobalamin? Methylcobalamin is the active form of B12 used by the body, while cyanocobalamin is synthetic and requires conversion. Methylcobalamin is preferred for neurological support and for those with methylation issues.

Is this product vegan? The product is labelled as suitable for vegetarians, but it may not be vegan as the source of B12 is not specified. Check the label or contact the manufacturer for vegan certification.

Can I take this if I have a B12 deficiency? This supplement can help address a deficiency, but consult a health care provider for proper diagnosis and dosage.

How long does one bottle last? With 30 lozenges per bottle and a recommended serving of one lozenge per day, each bottle provides a one-month supply.

Why does it support normal homocysteine metabolism? Vitamin B12 is a cofactor in the conversion of homocysteine to methionine, a process that requires folate. Adequate B12 ensures this cycle runs smoothly, supporting normal homocysteine levels.

Side Effects and Interactions

Vitamin B12 is considered safe and non-toxic, even at high doses. Some individuals may experience mild side effects like itching or a feeling of swelling, but these are rare. B12 can interact with certain medications, including neomycin, colchicine, and anti-seizure drugs, potentially reducing absorption. If you are undergoing medical treatment, discuss this supplement with your doctor. There are no known severe interactions, but always inform your health care provider about all supplements you take. Discontinue uses if any adverse reaction occurs. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, or taking medication, consult your doctor before uses.
