Overview of Vitamin B Complex Tablets

Vitamin B complex tablets are nutritional supplements containing B vitamins used to prevent and treat vitamin B deficiencies. This article provides key information on these tablets including the ingredients, uses, dosage, side effects and storage recommendations.

What is Vitamin B Complex?

Vitamin B complex refers to the family of water soluble vitamins that play vital roles in cell metabolism, hormone and red blood cell production, brain development, immune function and other essential processes.

There are 8 key members of the B complex vitamin family:

  • Vitamin B1 (thiamine)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin/nicotinamide)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6 (pyridoxine)
  • Vitamin B7 (biotin)
  • Vitamin B9 (folic acid)
  • Vitamin B12 (cobalamin)

Vitamin B complex supplements typically contain most or all of these vitamin types as they work synergistically together.

Ingredients of Vitamin B Complex Tablets

These tablets include the following key active B vitamin ingredients:

  • Vitamin B1 as thiamine mononitrate
  • Vitamin B2 as riboflavin
  • Vitamin B3 as nicotinamide

The tablets also contain these inactive ingredients:

  • Lactose monohydrate
  • Methylparaben (preservative)
  • Propylparaben (preservative)
  • Maize starch
  • Purified talc
  • Aerosil
  • Purified water

Those with lactose intolerance should consult their doctor before using this product.

Uses of Vitamin B Complex Tablets

Vitamin B complex tablets have two main uses:

  1. Preventing Vitamin B DeficiencyProviding B vitamins helps maintain adequate levels to support metabolic processes relying on these nutrients.
  2. Treating Vitamin B DeficiencyRestoring B vitamin levels can relieve deficiency symptoms related to fatigue, digestive issues, hormone changes, anemia, neurological problems and more.

Supplementing with B complex is appropriate when dietary intake proves insufficient to meet bodily demands. Certain health conditions, medications or genetic factors can impair vitamin utilization and increase needs as well.

Using vitamin B tablets requires an accurate diagnosis of deficiency or suboptimal levels from lab testing before routine supplementation. Self-treatment with these tablets is not appropriate.

Dosage Recommendations

General dosage guidelines for vitamin B complex tablets are:

  • 1-2 tablets daily
  • Or as professionally prescribed

However, dosage should be tailored to each patient’s age, health status and reason for treatment. Follow your doctor’s precise recommendations for your situation.

Overdose from water soluble B vitamins is rare as excess amounts flush from the body. But very high doses can possibly cause adverse reactions so stay within the recommended range.

Side Effects and Safety Information

When used as directed, vitamin B complex supplements rarely cause side effects or reactions. However, some safety considerations exist:

  • Allergic reactions are unlikely but possible if sensitive to vitamin ingredients or additives like lactose. Cease use if any symptoms develop.
  • Vitamin B6 above 200mg daily long term may possibly contribute to nerve damage. But typical B complex tablets provide less than 50mg.
  • Nicotinic acid form of B3 in high amounts can cause flushing, itching, headaches or other issues. But vitamin tablets use the no-flush nicotinamide form.
  • Those taking anticonvulsant, tuberculosis or Levodopa medications should seek medical guidance about using B vitamin supplements.

Consult a doctor immediately if any worrisome reaction occurs when taking vitamin B tablets. Also report side effects to your local health authorities.

How to Store Vitamin B Complex Tablets

To retain full potency and prevent degradation, Vitamin B complex tablets should be stored properly:

  • Store in a cool, dry place below 30°C
  • Keep away from direct light and humidity
  • Avoid heat or freezing
  • Keep bottle tightly sealed when not in use
  • Store out of reach of children
  • Check expiration dates and do not use if expired

Properly stored, vitamin B tablets typically retain their labeled potency until the imprinted expiration date. Any unused tablets should be discarded after this date.


In summary, vitamin B complex tablets can help prevent or resolve B vitamin deficiencies related to diet, health conditions or medications when confirmation of need from bloodwork exists.

Sensible supplementation combined with food sources can help maintain cell processes like growth, digestion, mental agility, hormone regulation and enzyme production.

However, improving diet through vitamin B rich foods should provide most needs for those without deficiency. Work with your healthcare provider to determine if adding vitamin B tablets makes sense in your situation.
