21st Century B-50 Complex Prolonged Release Tablets, 60 Tablets (Pack of 2)

What is B-Complex?

B vitamins are a group of eight water-soluble nutrients that work together to keep your body's energy production ticking over and your nervous system in good shape. The B-50 Complex provides these nutrients in a balanced ratio, with each B vitamin present at 50 mg or 50 mcg (except biotin and folic acid). This particular formulation from 21st Century employs prolonged release technology, which delivers the nutrients slowly to help maintain steady levels throughout the day. Whether you're looking to support your daily energy or maintain a healthy nervous system, a B-complex supplement can be a convenient addition to your routine.

Key Ingredients & Forms

Each tablet of 21st Century B-50 Complex contains the following B vitamins in their standard, well-researched forms:

• Thiamine (B1) – 50 mg: Supports energy metabolism and nerve function.
• Riboflavin (B2) – 50 mg: Helps with red blood cell production and energy release.
• Niacin (B3) – 50 mg: Aids in converting food to energy and maintaining healthy skin.
• Pantothenic Acid (B5) – 50 mg: Plays a role in hormone production and energy metabolism.
• Pyridoxine (B6) – 50 mg: Essential for amino acid metabolism and brain health.
• Biotin (B7) – 50 mcg: Supports healthy hair, skin, and nails.
• Folic Acid (B9) – 400 mcg: Important for DNA synthesis and cell division.
• Cyanocobalamin (B12) – 50 mcg: Supports nerve tissue health and red blood cell formation.

These are the standard forms commonly used in supplements. While methylated forms (such as methylfolate and methylcobalamin) are available for individuals with MTHFR gene variations, the forms in this product are effective for most people and have a long history of safe use.

Benefits of B-Complex

B vitamins play a critical role in converting the food you eat into usable energy. They help your body metabolise carbohydrates, fats, and proteins, making them essential for anyone with an active lifestyle or those who feel fatigued. Additionally, B vitamins support the nervous system by contributing to the maintenance of healthy nerve cells and neurotransmitter function. This B-50 Complex also includes prolonged release, which means the vitamins are released slowly over several hours, providing sustained energy support without the spikes and crashes associated with immediate-release Formulae.

How to Take B-Complex

For best results, take one prolonged release tablet daily with food and a full glass of water. Because B vitamins can be energising, it is recommended to take them in the morning or early afternoon to avoid potential interference with sleep. The prolonged release formulation allows for once-daily dosing, making it easy to incorporate into your routine. As with any supplement, store in a cool, dry place.

How to Choose the Right B-Complex

When selecting a B-complex supplement, consider factors such as the form of B vitamins (standard vs. methylated), dosage, and any special dietary needs. 21st Century B-50 Complex is gluten-free and contains no sugar, salt, yeast, preservatives, or artificial flavours or colours—making it a clean option for those with sensitivities. The prolonged release feature is ideal for individuals who want steady energy throughout the day without having to remember multiple doses. If you have specific genetic considerations like MTHFR mutations, you might prefer a methylated formula, but for general wellness this product offers excellent value and quality.

Potential Side Effects and Interactions

B-complex supplements are generally well-tolerated. One common and harmless side effect is bright yellow urine, which is due to excess riboflavin being excreted. Some individuals may experience mild nausea or digestive upset, especially on an empty stomach. If you have a medical condition or are taking medications, consult your doctor before starting any new supplement. This product is not known to interact with most medications, but always check with your GP.

Frequently Asked Questions

Is B-50 the same as B-100?

B-50 and B-100 refer to the dosage level of each B vitamin. B-100 typically contains 100 mg (or mcg) of most B vitamins, while B-50 contains half that amount. B-50 is suitable for general maintenance, while B-100 may be preferred for higher energy demands or as directed by a health care practitioner.

Can I take this on an empty stomach?

It is best to take with food to minimise any potential stomach discomfort. The prolonged release coating also works well with food.

How long does one bottle last?

Each bottle contains 60 tablets, which is a 60-day supply at the recommended serving of one tablet per day. The pack includes two bottles, providing a 120-day supply.
