NOW Foods Supplements, Vitamin B-100, Sustained Release, Energy Production*, Nervous System Health*, 100 Capsules

Key Ingredients and Forms

This B-100 formula contains a balanced blend of all eight B vitamins in their standard, well-absorbed forms. Thiamine (B1) supports carbohydrate metabolism and nerve function. Riboflavin (B2) is essential for energy production and antioxidant protection. Niacin (B3) supports energy metabolism and skin health; it is provided as niacinamide, which causes less flushing. Vitamin B6 is involved in amino acid metabolism and neurotransmitter synthesis. Folic acid is the synthetic form of folate, converted into active folate in the body. Vitamin B12 is provided as cyanocobalamin, a stable and common form. Biotin supports hair, skin, and nails. Pantothenic acid is a component of coenzyme A, critical for fatty acid metabolism. Choline supports liver and brain health, and inositol participates in cell signalling and mood regulation.

The sustained release matrix ensures that these nutrients are released gradually, improving absorption and reducing gastrointestinal upset.

Benefits of B-Complex

The B vitamins are fundamental to energy metabolism. They help convert carbohydrates, fats, and proteins into usable energy, making them crucial for anyone leading an active lifestyle or combating daily fatigue. Many users report feeling more alert and mentally clear when supplementing with a B-Complex.

• Energy Production: B vitamins act as coenzymes in metabolic pathways that generate ATP, the body's energy currency. Consistent energy support can help you stay productive and engaged throughout the day.
• Nervous System Health: These vitamins are vital for nerve cell function and neurotransmitter synthesis. Adequate levels of vitamin B6, B12, and folate are particularly linked to cognitive health and mood balance.
• Homocysteine Metabolism: Vitamin B6, B12, and folate help regulate homocysteine, an amino acid that, when elevated, is associated with cardiovascular risk. By maintaining healthy homocysteine levels, B-Complex supports heart health.
• Red Blood Cell Formation: B12 and folate are essential for producing healthy red blood cells, which carry oxygen throughout the body. This supports overall vitality and endurance.
• Skin, Hair, and Nail Health: Biotin (B7) is well-known for promoting strong nails and healthy hair, while niacin (B3) supports skin integrity.

How to Take B-Complex

For best results, take one capsule daily with a meal. Food can enhance absorption and reduce the chance of mild stomach discomfort. The sustained release formulation means you do not need to split doses; one capsule provides benefits throughout the day.

B-Complex supplements are often taken in the morning to align with the body's natural energy rhythms. Avoid taking them too close to bedtime, as some individuals may experience alertness that could interfere with sleep.

This supplement can be combined with other vitamins and minerals, but it is always wise to consult a health care professional before starting any new regimen, especially if you are taking medications or have existing health conditions.

Side Effects and Interactions

B vitamins are water-soluble, meaning excess amounts are excreted in urine. This often leads to a harmless but noticeable bright yellow coloration, which is normal and temporary. Some individuals may experience mild nausea or digestive upset, particularly when taking high doses on an empty stomach. Sustained release formulations like this one can help minimise such issues.

High doses of vitamin B6 (above 100 mg daily) over long periods may cause neuropathy in susceptible individuals. The amount in this product is within the tolerable upper intake level for adults, but prolonged uses of high-dose B6 should be monitored.

If you are taking medications for Parkinson's disease, seizures, or certain antibiotics, consult your doctor before starting B-Complex, as vitamins can interact with drug metabolism.

As always, pregnant or nursing women should seek medical advice before supplementing with high-dose vitamins.

How to Choose the Right B-Complex

When selecting a B-Complex supplement, consider your specific needs and preferences. This product stands out for several reasons:

• Sustained Release: Ideal for those who prefer once-daily dosage and want steady nutrient levels without multiple capsules.
• Certifications: It is Non-GMO, Vegan, Kosher, and free from gluten, soya, nuts, dairy, and eggs. This makes it suitable for individuals with dietary restrictions.
• Brand Reputation: NOW Foods has been a trusted manufacturer since 1968. They follow Good Manufacturing Practices (GMP) and have third-party certification for quality assurance.
• Dosage: B-100 provides a higher dose than many standard B-Complexes. This is beneficial for those with increased needs, such as vegetarians/vegans, older adults, or individuals under chronic stress.

If you are new to B-Complex supplementation, starting with a lower dose (like B-50) may be advisable. However, for those seeking robust support, B-100 sustained release is an excellent choice.

What is B-Complex?

B-Complex supplements deliver a complete spectrum of eight essential B vitamins that work synergistically to support overall wellness. Each B vitamin plays a unique role, from converting food into energy to supporting brain function and red blood cell formation. The term 'B-100' indicates that this formula contains approximately 100 mg of most B vitamins (except folate and B12, which are measured in micrograms), providing a robust dose for those seeking comprehensive support.

This particular B-Complex from NOW Foods features sustained release technology. Instead of releg all nutrients at once, the capsule gradually dissolves over several hours, allowing for steady absorption and lasting benefits throughout the day. This makes it an excellent choice for individuals who want consistent energy without the peaks and crashes associated with immediate-release formulae.

In addition to the eight B vitamins, this formula includes choline and inositol—nutrients often classified as part of the B-complex family. Choline supports liver function and brain health, while inositol is involved in cell signalling and mood regulation. Together, these ingredients create a comprehensive blend that addresses multiple aspects of metabolic and neurological health.

Frequently Asked Questions

Can I take B-100 if I am on a vegan diet? Yes, this supplement is vegan. Vitamin B12 is produced via fermentation, making it suitable for those avoiding animal products.

Will this product give me a burst of energy? B vitamins support energy metabolism, but they do not provide a stimulant effect like caffeine. Users often notice improved stamina and reduced fatigue over time.

Is sustained release better than immediate release? Sustained release offers convenience and steady blood levels, which can be preferable for maintaining consistent energy. Absorption may be slightly less than immediate release, but the difference is usually negligible.

Does this contain folic acid or methylfolate? It contains folic acid, which is the synthetic form of folate. If you have MTHFR genetic variations, you may prefer a methylfolate-based product, but for most people, folic acid is effective.

How long until the bottle lasts? With 100 capsules and a serving size of one per day, the bottle provides a 100-day supply.
