British Supplements - Clean Genuine Vitamin D3 + K2
They refuse to use flow agents like magnesium stearate or fillers. Their brand awareness in the US is near zero, but they are a cult favorite in the UK for 'cleanroom' manufacturing standards. This product features a 10,000 IU D3 paired with K2 (MK7). Unlike mass-market brands, the capsules contain only the active ingredients. The company is a small-batch operation that prioritizes ingredient purity over marketing, often selling out due to high demand from enthusiasts.
