21st Century B-12 1000 mcg Prolonged Release Tablets, 110 Tablets (Pack of 6)

Key Benefits of Vitamin B12

Discover 21St Century B-12 — Vitamin B12 is an essential nutrient that plays a vital role in many bodily processes. According to established European Food Safety Authority (EFSA) approvals, vitamin B12 contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal red blood cell formation, and normal homocysteine metabolism. It also contributes to the reduction of tiredness and fatigue. These well-recognized benefits make B12 a popular choice for those looking to support their overall wellbeing.

Who Should Take a Vitamin B12 Supplement?

While B12 is naturally found in animal products like meat, eggs, and dairy, certain groups are at higher risk of deficiency. Vegans and vegetarians often have limited dietary sources, as plant foods contain little to no B12. Older adults, especially those over 50, may experience reduced stomach acid production, which impairs absorption from food. Individuals with digestive disorders such as Crohn's disease, coeliac disease, or atrophic gastritis, as well as those who have undergone weight loss surgery, may require supplementation. Others who might benefit include people taking long-term medications like metformin or proton pump inhibitors, those with pernicious anaemia, and anyone looking to support their energy levels and cognitive function. Even if you don't fall into these categories, a B12 supplement can help maintain optimal levels, particularly if you experience chronic stress or have high physical demands.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is essential for several key bodily functions. It is necessary for the formation of red blood cells, proper neurological function, and DNA synthesis. Without adequate B12, the body cannot efficiently produce healthy red blood cells or maintain the protective myelin sheath that surrounds nerve fibres. A deficiency can lead to fatigue, weakness, cognitive difficulties, and nerve damage. The recommended daily intake for most adults is 2.4 mcg, but many people benefit from higher doses due to absorption issues or dietary restrictions. Since the body stores B12 in the liver, symptoms of deficiency may take years to appear, making consistent supplementation especially important for at-risk groups.

What Makes 21st Century B-12 Prolonged Release Special?

Not all B12 supplements are created equal. The 21st Century B-12 formula features a prolonged release design, which means the 1000 mcg of vitamin B12 is released gradually throughout the day. This slow delivery mimics the natural absorption process and helps maintain steady blood levels of B12, which can be especially beneficial for those with ongoing needs rather than an immediate peak. The supplement uses cyanocobalamin, a stable form of B12 that is widely studied and highly effective at raising B12 levels. Each tablet is Gluten-free, non-GM, and suitable for vegan and vegetarian lifestyles, making it accessible for a broad range of dietary preferences. With 110 tablets per bottle and six bottles included, this pack offers a convenient and cost-effective way to support your daily nutritional needs. The easy-to-swallow tablets are designed for once-daily uses with a meal, integrating seamlessly into any routine.

How to Take This Supplement

For best results, take one tablet daily with a meal or as directed by your health care provider. The prolonged release formula is optimised for once-daily uses; do not exceed the recommended dosage. If you have difficulty swallowing tablets, you may consider cutting the tablet in half, but do not crush or chew to preserve the extended-release properties. Store in a cool, dry place away from direct sunlight. As with any dietary supplement, it is wise to consult your health care professional before starting a new regimen, especially if you are pregnant, nursing, taking medications, or have a medical condition. Remember that supplements are intended to complement a balanced diet, not replace it.

Frequently Asked Questions

Can B12 be taken on an empty stomach?
B12 is water soluble and can be taken on an empty stomach, but taking it with food may help reduce any potential stomach discomfort. Consistency in timing is most important for maintaining routine.

Is 1000 mcg of B12 too much?
Vitamin B12 is considered safe even at high doses because excess is excreted in urine. The body only absorbs a small percentage of large oral doses, so 1000 mcg is a common and well tolerated supplementary amount for addressing deficiencies or absorption concerns.

How long does it take to notice benefits?
Results vary depending on your baseline levels and absorption. Some people report improved energy within a few weeks, while others may need several months of consistent uses to notice changes, particularly if addressing a long-standing deficiency.
