What is Active-B Complex and who is it for?
Active-B Complex is a high-strength B-vitamin formula providing thiamine, riboflavin sodium phosphate, nicotinamide, calcium pantothenate, pyridoxal 5-phosphate, biotin, mecobalamin (methylcobalamin), levomefolic acid (as Quatrefolic®) and choline bitartrate — all in activated or coenzyme forms. It is formulated for adults and provides two capsules daily as a single daily serve.
This formula suits people who want a comprehensive activated B-vitamin complex to support energy levels, nervous system health, cognitive function and a healthy stress response as part of their daily routine. Take 2 capsules daily with food, consistently for at least 3 months or as directed by your healthcare practitioner.
Fairfield Nutrition Thoughts
Active-B Complex is a well-specified activated B-vitamin formula from myBrainCo, an Australian family-owned brand. Every active is disclosed at a quantified amount, the B vitamins are in their coenzyme or methylated forms, and the formula includes Quatrefolic® as its methylfolate source alongside over 500 mg choline bitartrate per daily serve — a more complete combination than many single-focus B-complex products. It is manufactured in Australia in a TGA-licensed facility with third-party batch testing for purity, identity and heavy metals, which gives a clear picture of what you are getting.
Why This Formulation / How It Works
Each daily serve of two capsules provides the following actives at the amounts declared on the label:
- Thiamine hydrochloride 127.12 mg (equivalent to 50 mg thiamine per capsule / 100 mg per serve)
- Calcium pantothenate 110 mg (equivalent to 50 mg pantothenic acid per capsule / 100 mg per serve)
- Nicotinamide 100 mg per serve (50 mg per capsule)
- Pyridoxal 5-phosphate monohydrate 78.36 mg (equivalent to 25 mg pyridoxine per capsule / 50 mg per serve)
- Riboflavin sodium phosphate 65.78 mg (equivalent to 25 mg riboflavin per capsule / 50 mg per serve)
- Magnesium citrate 50 mg (equivalent to 3.86 mg elemental magnesium per capsule)
- Biotin 2.5 mg per serve (1.25 mg per capsule)
- Quatrefolic® levomefolate glucosamine 875.66 mcg (equivalent to 250 mcg levomefolic acid per capsule / 500 mcg per serve)
- Mecobalamin (co-methylcobalamin) 1000 mcg per serve (500 mcg per capsule)
- Choline bitartrate 501.26 mg (equivalent to 200 mg choline per serve)
The B vitamins in this formula — riboflavin sodium phosphate (B2), pyridoxal 5-phosphate (B6), mecobalamin (B12) and levomefolic acid (folate as Quatrefolic®) — are in their coenzyme or methylated forms. Quatrefolic® is a branded, stable form of methylfolate providing levomefolic acid. The formula is presented as a hard capsule (hypromellose), vegan, and free from gluten, dairy, soy, peanut, sesame, egg, GMOs, artificial colours, preservatives and sweeteners.
When to Consider This
This formula provides support for energy levels, nervous system health, cognitive function and a healthy stress response. It makes sense if you’re:
- An adult seeking a comprehensive activated B-vitamin complex for daily energy and cognitive support.
- Someone whose healthcare practitioner has identified a need for additional B-vitamin intake, including methylated forms of folate and B12.
- Working with a practitioner on nervous system or methylation support as part of a broader nutritional approach.
