Review: Outstanding B-Complex – Noticeable Energy Boost and Best Quality for the Price! - ntegrative Therapeutics Active B-Complex has been a game-changer for my daily energy levels and overall well-being! Within just a week of starting this supplement, I noticed a significant improvement in my mental clarity and sustained energy throughout the day. As someone who used to experience that afternoon energy crash regularly, I'm amazed at how much more consistent my energy feels now. What really sets this B-complex apart is the quality of ingredients and the fact that it contains active forms of B vitamins that are more readily absorbed by the body. I've tried other B-complex supplements before, but none have given me the noticeable results I'm experiencing with this one. My heart health was also a consideration, and knowing this supports cardiovascular function gives me added peace of mind. The capsules are easy to swallow and don't cause any stomach upset, even when I take them on an empty stomach occasionally. I appreciate that Integrative Therapeutics is a trusted, professional-grade brand that healthcare practitioners recommend. For the quality and potency, the price was the best I found compared to other professional supplement lines. I'm definitely planning to continue taking this long-term and will be ordering more before I run out. I've already recommended it to family members who were asking about my increased energy levels. If you're looking for a high-quality B-complex that actually delivers noticeable results for energy and heart health, this is absolutely worth trying. Solid 5 stars!
Review: A very high-quality and unique B-complex supplement formula! - I was very happy to find this specific formulation because it contains the right vitamins/nutrients I was searching for based on a recent study which I read, suggesting that taking certain vitamins/nutrients may halt glaucoma progression. Also, the specific forms noted in the study of each of the B vitamins are in this product. So far I take one capsule per day and no stomach issues. Two nice unexpected benefits are that I sleep better (I take the vitamins after supper) and my tinnitus has decreased. None of what I wrote above is to be considered medical advice, but just my personal experience. Please keep your "ACTIVE B-COMPLEX" capsules available on desertcart, INTEGRATIVE THERAPUETICS! I highly recommend this product and thankful I found it. B vitamins (in their optimal bioavailable-form) are so important.

## Questions & Answers

**Q: Is this a USP approved supplement?**
A: Since its founding in 1820, USP has helped secure the quality of the American drug supply.  These are not drugs, they are natural supplements and don't really fall into that category.  I'm sure that you know the answer to your question as there are only 3 brands of supplements that have this obscure certification and all 3 brands are low quality economy brands, not professional grade supplements. Kirkland brand is owned by Costco and is notoriously low quality and NatureMade isn't much better as it is grocery store economy brand owned by Otsuka Pharmaceutical.  The 3rd company isn't even worth mentioning as it is a new start up with a poorly maintained home-made website.  So, to answer you question, No, to my knowledge Integrative Therapeutics and every other quality brand in the market haven't bothered to be accredited by this Pharmaceutical Regulating body.

**Q: Is this B-complex derived from brewer's yeast?**
A: I spoke with the company and they stated that 1 of the ingredients in the Active B complex is derived from yeast

**Q: This contains inositol hexanicotinate instead of niacinamide. Is inositol hexanicotinate better than niacinamide?**
A: Inositol Hexaniacinate is also referred to as Flush-Free or No-Flush Niacin. As the nickname implies, it does not have the nasty side effects, which include itching, flushing, and hot flashes as Niacinamide/Nicotinamide does.

**Q: Why does the description of the product say "...with Folate...?"  Folate is not listed on the label.**
A: Look more closely at the label ;  folate is an abbreviation for it's full description. On label  form it says 'L-Methletetrahydrofolate'  (whew, hard to type that), plus lots of other longer words following containing 'folate' within them. Hope this helps!

### ⭐⭐⭐⭐⭐ I mean, I'm like pretty sure it's working...
*by O***N on May 5, 2025*

Ok. First day, Sunday, took 1 in the morning. Still fell asleep during church and dreamed about Jesus. So that was nice. Second day, Monday, is anyone ever ready for Monday? I knew I wouldn't be so I took 2 and started my day and oh my word! It's almost 11 and I feel like I should be way more tired cuz I usually am just a dead zombie all morning but I've got energy! It's weird and nice. I've also been fighting a cold, so I'm dosing up on vitamin C every day but not more than 1500-2000mg a day and it's only been like 2 days now since I started that too. Maybe it's a combination of both Or not but I feel like this is helping a lot. It almost feels like a replacement for methylcare, which is way more expensive and honestly I didn't get the same results at all when I was taking it. That was one of those, it's probably helping, kind of vitamins. But I feel like this one is helping right away!! Buy it! Buy it now!! On subscription so you never run out! Oh my gosh, I forgot to mention. I am like on the worst days of my period and I feel GREAT!! Like what??? I'm not agitated or irritable. It works you guys. Wow! It does nothing for cramps, you'll still need a bunch of Advil/Tylenol but this is awesome for what it's doing :D
