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.

  1. Charlotte Nieman (verified owner)

    I am low on B1 (Thiamine) which causes edema in the lower extremities.
    I take 2mL of your B-Complex IM/SQ for ~2 days and edema is completely gone.
    Difficult to find such a quality product.

  2. sandy.duke13 (verified owner)

    I feel this B complex is reasonably priced. I take it 2 x per week alternating with my B 12. Ordering is easy and shipping is reliable.

  3. Howard Yackee (verified owner)

    B-12 Direct has been very good to me for years!! Always reliable and timely. Thank You

  4. Hallie (verified owner)

    These injections work. It may seem expensive at first, but it is way cheaper and cost effective in the long run. The main point is they work!

  5. Brenna Baynard-Smith (verified owner)

    Received order in about 2 1/2 weeks. Well packaged and arrived in great condition. Works well. Loving it.

  6. jmdblondie (verified owner)

    I have been using the B12 from this company for a while. Prices are good and the product is the best. I also give injections to my elderly parents which helps
    So much highly recommend

  7. Leah Berokoff (verified owner)

    I discovered I may be low in B1 and was delighted to find this injectable, which is much more powerful and usable to me then oral capsized. This was more stingy then b12 but not horrible.

  8. Donald Sanders (verified owner)

    I am very happy to have found this site. The price of B complex and B 12 is about 25% less than I paid in the US. Injectable B complex is also difficult to find in the first world. Thank you for being there. Donald Sanders
