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.

    Works as advertised – somewhat of a sting, but the feeling lets you know you hit the muscle.

  5. David G. (verified owner)

    My parent required these supplements and they are satisfied with the quality and the overall delivery. I like to sincerely thank the providers for genuine product. We are ordering again.

    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.:)

  8. 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!

  9. Marilyn Childers (verified owner)

    I have been a loyal customer for many years and you are the best! I tried the B complex and I feel amazing. My blood work is so good that I was told by my doctor that it should be framed! Thanks for your great products and service. Without my b12 and bcomplex this body would be in trouble! THANK YOU!!! Marilyn Childers

  21. Ramon Kisoor (verified owner)

    im so happy that i can order 3 vitBplex again here :o)

    thank you

  22. 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.

  23. 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.

  24. Paritosh DUTTA (verified owner)

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

  25. angieetie (verified owner)

    I’ve been using B-complex and B-12 injectables for years. Keeps me going strong. Definitely notice decline in vigor and vitality when not using so try not to run out.

  26. Stephen Akers

    Shipping was good, packaged very good. I have only done 2 injections so far, am noticing an increase in energy. Very good product.

  27. Hallie Metzger (verified owner)

    Never use anything else. Great products and gives my body all the right vitamins.

  28. 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.

  29. 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.

  30. Joseph Watson

  32. Barbara Riley (verified owner)

    Although I ordered the wrong B12, my bad, the medication came on time. Your prices are definitely very good! Thank You! Barb

  33. Jennifer (verified owner)

    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.
