B Complex Injection Vitamins. Each ml contains vitamin B1, B2, B6, Nicotinamide (B3). Bottled in 10ml multi-use vials.

Each ml of B Complex contains:

  • Vitamin B1 100 mg
  • B2 0.5 mg
  • B6 1mg
  • Nicotinamide 100 mg (B3 amide)

 B Complex injection can sting slightly – “a mild bee sting”. This is normal, but might surprise users more familiar with B12 injections. Follow the advice of your medical professional. Injection is much more comfortable if combined with B12 as this dilutes the concentration.


B-Complex Cautions and Contradictions

Essentiel B vitamins are generally well tolerated with instances of sensitivity being rare. If you experience symptoms of an allergic reaction at any time while taking of this preparation discontinue use immediately. Individuals suffering from glaucoma, gout, hypertension or ulcers are advised not to take injections of B-100 complex.

B-100 complex can interfere with other medicines including but not limited to: levodopa, medicines containing oestrogen, hydrazine, certain anti epileptic drugs, phenobaritone, phenytoin, immunosuppressants and some drugs used to treat infections such as isoniazid, pyrazinamide, cycloserne and penicillamine.

Mega dosing any vitamin is strongly discouraged. Nicotinomide (vitamin B3) has been shown to be liver toxic in doses over 3G per day.

It is very important to consult with your doctor prior to taking of any supplement including the administering of injectable vitamins. We do not endorse self injection and recommend you seek the help of your medical health professional for administering this and all injectable vitamin products.

 B-Complex causes a stinging sensation while being injected comparable to a mild bee sting. This is normal and the sensation should subside shortly after the injection is completed.

Quality: B12 Direct works only with country of origin government licensed suppliers. We have independently tested our injectable vitamin B Complex for quality and safety at Mérieux NutriSciences (Vancouver Canada).

    As an RN, I know the value of B12. I ordered more today plus a vial of the multivitamin. I buy the 2000mcg vial and draw up 1/2 cc into an insulin syringe. So thankful for this company!

    Stuff is really good if you have low energy or any malady. If you eat a lot of sugar you really need this.
