THE PROMISE
B vitamins work together. This formula activates them all.
Most B-complex supplements use cheap, unactivated forms that require your liver to convert before they become usable. Activated B-Complex skips that step — delivering the bioactive forms your cells can put to work immediately.
All Eight B Vitamins
B1, B2, B3, B5, B6, B7, B9, and B12 — the complete spectrum in one formula. Every B vitamin plays a distinct role in energy metabolism, neurological health, and cellular repair.*
Activated Forms Only
Methylcobalamin (B12), Pyridoxal-5-Phosphate (B6), and Quatrefolic® (5-MTHF folate) — the bioavailable, active forms your cells can use immediately without conversion.
Quatrefolic® Folate
The leading activated folate form — far superior to folic acid in absorption and utilization. Critical for the ~40% of people with MTHFR gene variants who cannot convert standard folic acid.
Energy + Methylation
B vitamins are essential cofactors for methylation — the biochemical process governing DNA repair, neurotransmitter synthesis, detoxification, and cellular energy production.*
WHY IT WORKS
Eight vitamins. One unified system.
Sustained Energy Production
B vitamins are essential cofactors in the Krebs cycle — converting carbohydrates, fats, and proteins into ATP. Without adequate B vitamins, every cell in your body produces energy less efficiently.*
Neurological & Cognitive Health
B6, B9, and B12 are critical for neurotransmitter synthesis — serotonin, dopamine, and GABA. Deficiency is directly linked to fatigue, brain fog, mood instability, and reduced cognitive wellness.*
Methylation & DNA Repair
The activated folate (5-MTHF) and methylcobalamin in this formula are the rate-limiting cofactors in methylation — one of the most important biochemical processes governing long-term cellular health.*
Heart & Skin Health
B vitamins regulate homocysteine — high levels are a major cardiovascular risk factor. Biotin (B7) and riboflavin (B2) also support skin integrity, hair growth, and nail strength.*

YOUR METHOD
Make it your method,
not just a habit
Activated B-Complex is designed to fuel your day from the inside out — starting with breakfast and sustaining through your highest-demand hours.
MORNING
Take 1–2 capsules with your morning meal. B vitamins are water-soluble and absorb well with food. Taking with breakfast ensures the energy-metabolizing B vitamins are active during your peak hours.*
WHY IT WORKS
B vitamins activate the enzymes that convert food into cellular energy (ATP) — so morning dosing aligns with your body's highest energy demand window.*
SPLIT DOSE
On high-demand days, take an additional capsule with lunch. B vitamins are water-soluble — any excess is excreted, not stored. A midday dose helps sustain energy metabolism through afternoon hours.*
WHY IT WORKS
B12 and B6 are rate-limiting cofactors for dopamine and serotonin synthesis — supporting mood and cognitive clarity through the afternoon dip most people experience.*
DAILY HABIT
B vitamins work cumulatively. Daily supplementation maintains optimal tissue levels of all eight vitamins — particularly important for B12, which can take weeks to normalize if deficient.*
WHY IT WORKS
Plasma B12 levels stabilize within 2–4 weeks of daily supplementation. Neurological and energy benefits compound over consistent daily use.*
HOW TO TAKE IT
Simple by design. Effective by science.
One to two capsules with breakfast. That's the entire protocol.

Founder & Chief Curator · Est. 1999Why It Matters
Built by someone with
personal stakes in it.
Devin started Pure Prescriptions in 1999 after battling Hodgkin's Lymphoma and losing his father to leukemia. That experience made him the most stubborn kind of formulator — one who refuses to ship anything he wouldn't take himself.
Every ingredient here earned its place through clinical evidence, third-party testing, and that same personal lens — the five collagen types, the organic fruiting-body mushrooms, the co-factors. Nothing is decorative.
"Pure Prescriptions has always been more personal than corporate. Built by family. Still independent."

The Science
Activated.
Not converted.
Most B-complex formulas use cheap, synthetic forms that your liver must convert before your cells can use them — a process that fails in people with MTHFR variants, liver stress, or absorption issues. Activated B-Complex delivers the end-state, bioavailable forms directly.
- Methylcobalamin B12 — the neuro-active form
- Quatrefolic® 5-MTHF — activated folate
- Pyridoxal-5-Phosphate (P5P) — active B6
- Riboflavin-5-Phosphate — active B2
- No cyanocobalamin; folate and capsule ingredients follow the product label

Everything you need to know.
Honest answers — no marketing spin. If your question isn’t here, our team responds within one business day.
Standard B-complex formulas use synthetic forms — folic acid, cyanocobalamin — that require your liver to convert them into active forms before your cells can use them. People with MTHFR gene variants, liver stress, or malabsorption issues may not convert these efficiently. Activated B-Complex provides the bioavailable end-state forms directly: methylcobalamin (B12), 5-MTHF folate, and P5P (B6).
Quatrefolic® is the brand name for glucosamine salt of 5-methyltetrahydrofolate — the most bioavailable form of folate available. Unlike synthetic folic acid, it does not require any enzymatic conversion and is directly usable for methylation and DNA synthesis. It’s particularly important for those with MTHFR variants, which affect up to 40% of the population.
Yes — take the second capsule with a meal as part of the label’s 1 capsule twice daily suggested use. B vitamins are water-soluble, so excess is safely excreted. A midday dose can help sustain energy metabolism and neurotransmitter production through the afternoon hours.
Yes — this is completely normal and expected. Riboflavin (B2) is intensely yellow and excreted in urine when B vitamin levels are sufficient. This is a sign the formula is working and being absorbed, not a cause for concern.
This formula contains Quatrefolic® folate. However, always consult your OB or healthcare provider before starting any supplement during pregnancy or nursing.
Doctor’s Protocol
How I’d build your energy foundation.
“Activated B vitamins unlock the methylation cycle. CoQ10 captures the energy those pathways produce. Magnesium ensures every enzymatic reaction fires correctly. Omega-3s protect the neurological infrastructure. Each layer depends on the one before it.”
