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)

IMPORTANT! 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 health 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 administration of injectable vitamins. We do not endorse self injection and recommend you seek the help of your health professional for administering this and all injectable vitamin products.

IMPORTANT! 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.

    I have been using both B12 and B complex injections for about 1 year and it really makes a difference in providing me with energy, great mood and ordering is easy, fast and the product is great. I will definitely tell my friends and highly recommend vitaminB12direct.:)

  10. Teresa Mata Anderson

    I was skeptical at first because this company is so much cheaper than where I usually get my Vitamin B injections and it ships from outside the united states. However, it is the BEST vitamin I found so far! my body is able to absorb and utilize it BETTER than the other well respected US company, at a FRACTION of the cost! I am a thyroid cancer survivor, and have had a host of issues lately with low thyroid, anemia, low B and low potassium. Within days I could tell a difference! thank you for provided this very valuable service/product at an affordable cost to those of us with out resources nor insurance. Highly recommend this company and i’m ordering again today. Life changer!
