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 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.

 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).

  7. JUDITH BOYD (verified owner)

    I have used the B complex and after a few months noticed my nails are looking better. I don’t make vitamin B in my body and have chest pains without the
    b complex.

  8. Ramon Kisoor (verified owner)

    thank you

  9. kristy3111 (verified owner)

    I have been purchasing my B12 injections from vitaminb12direct for several years and I feel they are the absolute best in the online market. They began adding other products that I was excited to try and this is one of them. I have dabbled in trying the identical vitamins in pill, capsule, sublingual and other forms but none are more effective than injections. I find that my body absorbs them more effectively and it doesn’t take months to reap the benefits.

  10. Romona Stewart (verified owner)

    love this product. It is a really great quality and it works. I feel energetic and eat a lot less. I was paying high amounts for injections and it’s easy for me to do it myself. I will continue to order.

    Very pleased with the product. It was easy to order.

  12. angieetie (verified owner)

  15. Bernadette Cairns (verified owner)

    First I would like to address B12 Direct service who was very knowledgeable with all the products available for purchase. I was assured great product, and if we had any questions to call direct. In the times we live in with technology making it almost impossible to get good old fashion service, it was nice to hear a voice instead if a machine when I placed my call. The product was delivered on time as promised and I am so happy with my purchase. Excellent product, customer service and speedy delivery.

  16. P H 1980 (verified owner)

    i ordered this along with B12. i used the complex the exact same brand when in lived in thailand, so i knew it was good stuff. it helped my energy levels to maintain gym and bodybuilding at the time, good for fatigue. The B12 gave me a terrible headache all day a few hours after injection , so ill just stick with the B complex…arrived in around 2 weeks. Good service.

    I placed an order on February 8, 2021. Today is February 20, 2021 and the order still has not even shipped. I’ve tried to call customer service and no one calls me back. I’m starting to believe these reviews are fake and this is a scam.

    Excellent product as well awesome service, I would highly recommend vitamin b-12 direct, I never had any issue with them. I love the b-complex as well as the b-12, I have ordered both 1,000 and 2,000 mcg. Especially having a bad liver and always tired, I usually get my b-12 from the pharmacy until i ran into this company…. Able to have more energy and get through the day and wake up better. Can feel a big difference taking this over the pills…..
