Vitamin D3 + K2 + C

One chewable a day. Three foundational nutrients, working as one. Vitamin D is the nutrient your immune system, your mood and your bones all quietly depend on — and one that many New Zealanders run low on through the darker months. Re:inforce pairs Vitamin D3 with Vitamin K2 and Vitamin C so the three do more together than any could alone: D3 to support healthy immune function and positive mood, K2 to help direct calcium into the bones and teeth, and C to round out a daily base of immune nutrients. The everyday foundation beneath the Aevum stack.

Everyday Immune Support: Vitamin D3 and Vitamin C are two of the nutrients your immune system leans on most. Together they support healthy immune function day to day — the quiet groundwork that matters most through winter, travel and the busy stretches when your defences are asked to do more.

Mood & Vitality: Vitamin D isn't only about immunity. It plays a role in supporting positive mood and a sense of everyday vitality — the reason low levels so often track with the shorter, greyer days. A daily D3 base helps keep that foundation topped up year-round.

Strong Bones & Teeth: D3 and K2 are a deliberate pairing. Vitamin D helps your body absorb calcium; Vitamin K2 helps direct that calcium into the bones and teeth where it belongs. Support for strong, healthy bones — the framework longevity is built on.

Vitamin D3 (as cholecalciferol): 1000 IU
Vitamin K2 (as menaquinone mk-7): 30 mcg
Vitamin C (as ascorbic acid): 40 mg

Benefits

The foundation of Immunity

Ingredients (Each capsule contains)

Vitamin D3 (as cholecalciferol)

1000 IU
Vitamin D3 (as cholecalciferol)

The keystone of the formula. Vitamin D behaves less like a single-job vitamin and more like a signal your whole body reads — immune cells, bone-building cells and mood-related pathways all respond to it. D3 (cholecalciferol) is the same form your skin makes from sunlight and the form the body uses most readily, which is exactly why it matters here: sun exposure drops through a New Zealand winter and for anyone who spends the day indoors, and a daily D3 base helps keep that foundation topped up. It's the reason the other two ingredients are built around it.

Origin Cholecalciferol — the body-ready form of Vitamin D
Benefits Supports healthy immune function, positive mood, and calcium absorption for bone
Actives Vitamin D3

Vitamin K2 (as menaquinone MK-7)

30mcg
Vitamin K2 (as menaquinone MK-7)

Vitamin D's partner. D3 helps your body absorb more calcium — but absorption is only half the job; that calcium still has to reach the bones and teeth where it's needed. That's K2's role. We use the MK-7 form specifically because it stays active in the body far longer than shorter-chain K2, so a single daily tablet keeps working between doses. Pairing D3 with K2 is a deliberate design choice: it's what turns "more calcium absorbed" into "calcium directed to the bones.

Origin Menaquinone-7 (MK-7) — the long-acting form of Vitamin K2
Benefits Helps direct absorbed calcium into the bones and teeth
Actives

Vitamin C (as ascorbic acid)

40mg
Vitamin C (as ascorbic acid)

The everyday immune nutrient, and a natural companion to Vitamin D. Vitamin C is one of the most recognised nutrients for supporting healthy immune function, and it doubles as an antioxidant that helps protect cells from everyday oxidative stress. Here it's a measured addition rather than a mega-dose — enough to round out a daily immune base alongside D3, in a form (ascorbic acid) that's well-established and well-tolerated.

Origin Ascorbic acid — the standard, well-tolerated form of Vitamin C
Benefits Supports healthy immune function + antioxidant support

Frequently Asked Questions

A once-daily chewable that combines three foundational nutrients — Vitamin D3 (1000 IU), Vitamin K2 as MK-7 (30mcg) and Vitamin C (40mg) — to support healthy immune function, positive mood, and strong bones and teeth. It's the everyday base layer of the Aevum range.

Because they work better together. Vitamin D3 helps your body absorb calcium and supports immune function and mood. Vitamin K2 helps direct that absorbed calcium into the bones and teeth. Vitamin C adds a second well-known immune nutrient to the base. It's a small formula built around how these nutrients actually cooperate — not a single ingredient in isolation.

One chewable tablet per day. It's fat-soluble, so many people take it with a meal. There's no wrong time of day — consistency matters more than timing.

Anyone wanting a simple daily foundation for immune, mood and bone support — particularly through the winter months, or if you spend most of your day indoors or out of the sun. Always read the label and take only as directed.

Yes. Re:inforce is designed as the everyday foundation beneath the stack — a broad daily base, where Re:juvenate Pro does the deeper immune and cellular work. Many people run both.

It's suitable for vegetarians. It is not vegan, and it contains milk— so it isn't suitable if you have a dairy allergy. It's also gluten-free, GMO-free and GMP-manufactured.

Vitamin D works at the level of your baseline, which shifts gradually. Dietary supplements can take time to have their full effect, so think of it as a steady daily foundation rather than something you feel on the day. Consistency is the point.

Formulated, tabletted and packed in New Zealand from imported ingredients, manufactured by PharmaNZ Limited to pharmaceutical-grade (GMP) standards — the same standards as the rest of the Aevum range.

Vitamin K can interact with some medications, particularly blood thinners. If you're on prescription medication, check with your healthcare provider before starting.
