Transparency Index

6.9/10

Acceptable Excellent value for a basic D3+K2 stack. Those wanting more confidence through independent testing will pay more elsewhere.

Rating breakdown

Evidence for ingredient 8.0/10

The D3+K2 combination has solid evidence for bone health and immune function. EFSA health claims approved for D3.

Value for money 9.0/10

€0.09 per day is exceptionally cheap. Lasts 180 days — few supplements match this price per daily dose.

Product quality 6.0/10

Made in Germany, GMP-compliant. No known quality issues. Brand recognition is moderate.

Label honesty 8.0/10

Clear labeling without inflated claims. Dose and ingredients are transparently listed.

Third-party testing 4.0/10

No independent third-party certification. GMP manufacturing is the only quality indicator.

Product Description

Fairvital is a German direct-to-consumer supplement brand. This D3+K2 product delivers 1000 IU vitamin D3 (cholecalciferol) combined with 200 µg vitamin K2 as MK-7 in a single daily capsule.

What We Like

  • Price: Barely any comparable product costs less than €0.10 per day
  • Made in Germany: GMP-certified production under EU regulations
  • Sensible combo: D3 and K2 MK-7 complement each other — K2 supports proper calcium utilization

What We’re Missing

  • Low D3 dose: 1000 IU is insufficient for many deficient adults — typical recommendations are 2000–4000 IU
  • No third-party certification
  • MK-7 source not disclosed: Synthetic vs. fermented is not stated

Usage Recommendation

1 capsule daily with a fat-containing meal. Vitamin D is fat-soluble — absorption drops significantly without dietary fat.

Ingredient dossier

Low vitamin D levels are common in northern climates. Supplementation is comparatively well studied in deficiency; K2 is often combined but has weaker standalone evidence.
