BioTrace Phyto D3 Complex 60 Capsules – Vegan Vitamin D3 from Sprouted Buckwheat with K2 & Magnesium Glycinate

BioTrace Phyto D3 Complex is a premium vegan vitamin D3 supplement — most vitamin D3 supplements are derived from lanolin (sheep wool), but Phyto D3 uses Cultavit®, a natural plant-sourced vitamin D3 derived from the germ of sprouted buckwheat (Fagopyrum esculentum). Combined with Vitamin K2-7 (MenaquinGold®) and magnesium glycinate (for enhanced intestinal absorption), Phyto D3 provides comprehensive support for immune function, bone health, cardiovascular health, and mood balance in a single daily capsule. Each capsule delivers 1000IU vitamin D3, 45mcg vitamin K2-7, and 45mg elemental magnesium.

• Cultavit® plant-sourced vegan D3 from sprouted buckwheat — not animal-derived
• 1000IU Vitamin D3 (cholecalciferol) per capsule
• 45mcg MenaquinGold® Vitamin K2-7 for calcium direction to bones not arteries
• Magnesium bisglycinate for enhanced D3 absorption and bone/heart support
• 60 capsules — BioTrace NZ quality

Frequently Asked Questions

What is Cultavit® and why is plant-sourced D3 significant?

Cultavit® is a patented plant-derived vitamin D3 produced from sprouted buckwheat germ — providing the same cholecalciferol (D3) form as conventional animal-derived supplements, but from a completely plant-based source. Standard D3 supplements use lanolin (from sheep wool), making them unsuitable for vegans and some religious dietary restrictions. Cultavit® D3 is chemically identical to animal-derived D3 and has the same biological activity, providing an authentic vegan D3 option.

Why combine Vitamin D3 with Vitamin K2?

Vitamins D3 and K2 work synergistically for calcium metabolism. D3 increases intestinal calcium absorption — but without K2, this extra calcium may deposit in arteries (calcification) rather than being directed to bones. Vitamin K2-7 (as MenaquinGold® menaquinone-7) activates matrix Gla-protein (MGP) and osteocalcin — proteins that direct calcium specifically into bone tissue and away from arterial walls. The D3+K2 combination is the evidence-based pairing for optimal bone mineralisation and cardiovascular safety.

Why is New Zealand particularly prone to vitamin D deficiency?

Despite NZ's sunny reputation, vitamin D deficiency affects 33–84% of New Zealanders depending on age, skin tone, and sun exposure. Key reasons: most people spend the majority of daylight hours indoors; sun protection (clothing, sunscreen) blocks the UV-B needed for D3 synthesis; darker skin tones require more sun exposure to produce the same D3 as lighter skin; and NZ's southern latitude means low UV-B intensity in winter months. Supplementation is widely recommended year-round for many New Zealanders.

What does Vitamin D3 do for the immune system?

Vitamin D3 receptors are present on virtually every immune cell type — T cells, B cells, macrophages, natural killer cells, and dendritic cells. D3 modulates both innate and adaptive immunity: it enhances the antimicrobial peptide response (front-line defence), reduces excessive inflammatory cytokine production, and supports the regulatory immune processes that prevent autoimmune overreaction. Vitamin D deficiency is consistently associated with increased infection susceptibility and poor immune regulation.

Who is BioTrace Phyto D3 most suitable for?

Phyto D3 is ideal for: vegans and vegetarians requiring a plant-based D3 source, people with vitamin D deficiency (very common in NZ), those wanting the added bone and cardiovascular benefit of K2 alongside D3, people seeking a complete D3+K2+magnesium combination in one capsule, and anyone avoiding animal-derived supplements for religious, ethical, or dietary reasons.
