What customers say
Customers overwhelmingly praise AOR's Advanced B Complex for its high-quality, bioavailable forms of B vitamins that enhance energy, mood, and overall health. Many appreciate the vegetarian capsules and the absence of common allergens like gluten, corn, wheat, dairy, and soy. Users report significant improvements in well-being and vitality, with some noting it as a staple in their daily routine for years. The product is also commended for its clean ingredient list and scientific formulation. However, a few users mentioned issues such as excessive Niacin (B3) content and occasional digestive discomfort. Despite these minor drawbacks, the majority find it gentle on the stomach without causing nausea or other typical side effects associated with B vitamins. The brand AOR is trusted by many who have tried various other brands but prefer this one for its effectiveness and purity.

Amazing without magnesium stereate
Verified purchase
No magneisum stereate and other unnecessary ingredients is a plus point for sure. I take it with betaine powder so as to balance out TMG to help with vitamin Bs in the body. I brought this to help with my energy level and vitality. And I chose this particular brand because it's vegan and I will always support ethical company towards the animal and people. Wishing everybody here a life full of energy and abled body to enjoy this lifetime. And please never ever think that it's too expensive to invest in yourself~ for good health is the first step to a great life as with a strong energetic body and sharp mind, we can accomplish anything we want. Have a lovely day ahead everyone!

The Best.
Verified purchase
I trust AOR. I've yet to be disappointed with any of their products. After trying many vitamin B complexes I keep coming back to this one. I don't pee neon yellow while taking this and it has benfotiamine and methylated forms that are (supposedly) better absorbed in the correct ratios. Basically, it keeps all your bases covered for the important B vitamins and is what I settled on after years of searching.

Truly full spectrum
Verified purchase
I have decided to take this supplement for my nervous system, as B6 in this bottle is in a form I was looking for (p5p is a form suggested by my general practicioner as it has great absorption and potency). Size of the bottle is perfect for three month course.

Good product if you don't want to buy Vitamin B complex and BenfoTiamine separately. This product combines them! Benfotiamine may be beneficial if you have Diabetes or Alzheimer Disease. Or advanced age?

B Complex in active form
Verified purchase
This has the vitamin Bs in active form and does not dilute them by including the inactive forms as well. The only exceptions are niacin, which is in the form of inositol hexanicotinate, and pantothenic acid which is included as well as its active form, pantethine.

Helpful for nerve support
Verified purchase
I’ve been taking this B Complex for a little while and I really like it. The capsules are easy to swallow and don’t upset my stomach. What surprised me the most is that I noticed my hands feel less numb than before. I wasn’t expecting such a clear difference, but it really seems to help with nerve support and overall energy. The quality feels high, and I also appreciate that it’s vegan and non-GMO. Definitely planning to continue using it.

Incredible quality, worth the price tag
Verified purchase
Hands down, one of the best B-complex supplements I’ve ever tried. The forms of B vitamins are active and highly absorbable, so you actually feel the benefits. Within days, I experienced a boost in mental clarity and steady energy, no jitters, just a smooth lift. It’s also been great for my mood and stress levels. I love that AOR is committed to high-quality formulations, and this one definitely delivers on its promises. Worth every penny.
