UK Supplement Brand Nutrivity Relaunches Best-Selling Vitamin D3 + K2 with New Packaging and Year-Round Supply Format
Nutrivity's best-selling D3+K2 formula, now in new packaging - high-strength, plant-based, and made in the UK for over 300,000 cus
Manchester-based Nutrivity marks 8 years of trading and 300,000+ customers served with a refreshed high-strength vegan D3+K2 product designed for the UK's growing supplement-savvy consumer
Manchester, UK - February 2026 - Nutrivity, a UK-manufactured health supplement brand serving over 300,000 customers since its launch eight years ago, has relaunched its best-selling high-strength Vitamin D3 4000 IU + K2 MK7 supplement with updated packaging designed to reflect the brand's premium, clean-label positioning.
The updated product retains the same GMP-certified formula - 4,000 IU of plant-based Vitamin D3 (sourced from lichen) and 100μg of Vitamin K2 MK-7 (derived from fermented soybeans) - while introducing letterbox-friendly, resealable pouch packaging that improves shelf life and reduces delivery friction for UK customers.
Why D3 + K2 and Why Now
The UK has one of the highest rates of Vitamin D insufficiency in Europe, a well-documented public health concern that intensifies during autumn and winter months. NHS guidance recommends Vitamin D supplementation for all adults during this period. Despite this, the majority of mass-market D3 products available in the UK remain low-strength, contain gelatin-based capsules that exclude vegan consumers, and are manufactured overseas.
Nutrivity's reformulated product addresses all three gaps in a single SKU: high strength at 4,000 IU, fully vegan with plant-derived D3 and K2, and manufactured in the United Kingdom to GMP quality standards.
"What we kept hearing from customers was that they'd tried cheaper options and either didn't see results or couldn't trust the sourcing," said a spokesperson for Nutrivity. "After eight years and over 300,000 orders, the repeat purchase rate speaks for itself. Customers come back because the product is clean, the dose is meaningful, and it's made here in the UK."
The relaunched product offers:
4,000 IU Vitamin D3 - plant-based, from lichen
100μg Vitamin K2 MK-7 - from natto (fermented soybeans), chosen for superior bioavailability among K2 forms
365 tablets - a full 12-month supply, at just 3.5p per daily serving
GMP Certified, UK Manufactured - produced to pharmaceutical-grade quality standards
Clean formula - free from allergens, unnecessary fillers, and binders
Halal and Vegan certified - serving a demographic consistently underserved by mainstream supplement brands
Letterbox-friendly packaging - slim resealable pouch that fits through standard UK letterboxes without requiring a redelivery
The product is available exclusively through Nutrivity's online store with free tracked UK delivery on all orders.
