What it supports
Two essentials. High potency.
B12 and D3 are two of the most commonly under-met daily vitamins. We dosed both at the higher end of the well-tolerated range.
Steady daily energy
B12 plays a central role in red blood cell formation and the energy pathways of every cell in your body.
Mood and nervous system
Both B12 and D3 are involved in neurotransmitter regulation — supporting a steady, even mood across the day.
Immune resilience
Vitamin D3 is one of the most studied micronutrients for healthy immune function across all four seasons.
Bone and calcium balance
D3 supports the absorption of calcium and is foundational for long-term bone density.

Questions, answered
Good to know.
Why methylcobalamin instead of cyanocobalamin?+
Methylcobalamin is the active form of B12 your cells use directly. Cyanocobalamin (the form in most cheap supplements) has to be converted by the body first.
When will I notice a difference?+
Energy effects often show up in the first 1–2 weeks. Mood and immune benefits build over 4–6 weeks as D3 levels normalize.
Do I need to take it with food?+
Vitamin D is fat-soluble, so taking it with a meal that contains some fat helps absorption. We suggest one tablet with breakfast and one with dinner.
Can I take it alongside a multivitamin?+
In most cases yes, but check your multi's D3 and B12 levels to avoid stacking too high. A licensed clinician can help if you're unsure.

How it works
Consistency compounds.
Most people notice meaningful changes by week three. Here's the typical arc.
D 1
Day 1 · Begin
One capsule morning, one evening. No loading dose. Slot it into a meal you already have.
W 1
Week 1 · Settle
The body starts to notice the daily rhythm. Subtle shifts in energy, sleep, or wind-down begin to show up.
W 3
Week 3 · Lift
Effects become more consistent. Most people notice the meaningful shift here.
W 8
Week 8 · Baseline
The full effect settles in. What used to be occasional becomes the new default.
