Key Function
Bulking agent, binder, disintegrant.
What it's used for
Pharmaceutical and food additive, mainly as an excipient in tablets and capsules.
Key Benefits
Acts as a fiber (though typically in small amounts in supplements), provides structure to tablets, generally recognized as safe.
Science Behind It
Microcrystalline cellulose (MCC) is a purified, partially depolymerized cellulose. It's an inert, insoluble dietary fiber that is not digested or absorbed by the body. In supplement formulations, its primary role is as a binder to hold ingredients together, a filler or bulking agent to increase tablet size, and a disintegrant to help tablets break down in the digestive tract.

Calcium and phosphorus supplementation, used as a dietary supplement and excipient in tablets.
Key Benefits
A source of calcium and phosphorus, which are needed for the maintenance of normal bones and teeth.
Science Behind It
Di Calcium Phosphate contains both calcium and phosphorus, two essential minerals. Calcium is needed for the maintenance of normal bones and teeth; phosphorus contributes to normal energy-yielding metabolism and the maintenance of normal bones and teeth. In supplements it also acts as a mineral source and a binder.

Science Behind It
Folic acid (or folate, its natural form) is essential for DNA synthesis and cell division, and is therefore especially important during pregnancy, when it contributes to maternal tissue growth. It works alongside Vitamin B12 to support normal blood formation and contributes to normal homocysteine metabolism and the reduction of tiredness and fatigue.

Benefits
Why take a Vitamin B Complex?
The eight B vitamins each play a different role in the body, but they work most effectively together. Most people don't get optimal levels from food alone — particularly those following plant-based diets, anyone over 40, people under chronic stress, and those who exercise frequently. A daily B complex bridges that gap.
What thecary's Vitamin B Complex supports
Energy and metabolism. B1, B2, B3, B5, B6, B7 and B12 all contribute to normal energy-yielding metabolism — helping your body convert food into the energy your cells actually use.
Reduced tiredness and fatigue. B2, B3, B5, B6, B9 and B12 contribute to the reduction of tiredness and fatigue, which is why many people notice a difference within two to four weeks of consistent use.
Nervous system and psychological function. B1, B2, B3, B6, B7 and B12 support normal functioning of the nervous system. B6, B9 and B12 also contribute to normal psychological function, including focus and mental clarity.
Immune function. B6, B9 and B12 contribute to the normal function of the immune system.
Red blood cell formation. B6, B9 and B12 support normal red blood cell formation and the transport of oxygen through the body.
Healthy skin, hair and eyes. Biotin (B7) contributes to the maintenance of normal hair and skin. Riboflavin (B2) contributes to the maintenance of normal vision and skin.
How to Take
How to take Vitamin B Complex
Take one tablet daily with food and water, ideally in the morning. B vitamins are water-soluble, so consistency matters more than dose — taking your B complex at the same time each day produces the most reliable results.
Do not exceed the recommended dose. Food supplements are not a substitute for a balanced diet and healthy lifestyle. If you are pregnant, breastfeeding, taking medication or under medical supervision, consult your GP before use.

FAQ
What does Vitamin B Complex do?
A B Complex provides all eight B vitamins in one supplement. Together they support energy production, reduce tiredness and fatigue, and contribute to normal nervous system, psychological and immune function. They also play a role in red blood cell formation and healthy skin, hair and eyes.
When is the best time to take Vitamin B Complex?
Most people take it in the morning with breakfast. B vitamins are water-soluble and can have a mild energising effect, so taking them earlier in the day is generally preferred over the evening.
Is thecary's Vitamin B Complex vegan?
Yes. Our Vitamin B Complex is fully vegan, GMO-free, and made in the UK in an FSSC 22000 certified facility. The B12 we use is methylcobalamin — the bioactive, plant-based form.
How long does it take to feel the effects?
Most people notice a difference in energy and focus within two to four weeks of daily use. B vitamins build up gradually and consistency is more important than dose.
Can I take it alongside other supplements?
Yes — B Complex pairs well with Iron, Magnesium and Marine Collagen, and is commonly taken alongside NMN as part of an energy and longevity stack. If you're already taking a multivitamin, check that you're not doubling up on B vitamins beyond the recommended levels.
Why does Vitamin B make my urine bright yellow?
Riboflavin (B2) is naturally yellow and any excess that your body doesn't use is excreted through urine. This is harmless and a sign that your body is regulating B vitamin levels normally.
Does it contain Folic Acid or Folate?
We use natural folate (B9), the form your body uses directly, rather than synthetic folic acid which requires conversion in the liver.
