Transparency Index

7.3/10

Recommended A very usable standard recommendation for vitamin B12 — especially for vegan or vegetarian diets.

Rating breakdown

Evidence for ingredient 9.0/10

Vitamin B12 is one of the most well-justified supplement cases for vegan or vegetarian diets. Evidence for deficiency prevention and correction is strong.

Value for money 8.0/10

€0.19 per day for 90 days is fair, even if cheaper B12 options exist. For two active forms combined, the price is reasonable.

Product quality 7.0/10

Made in Germany with vegan capsules and a clean positioning. Not a premium lab brand, but solid overall.

Label honesty 8.0/10

Fairvital communicates the B12 forms transparently and stays within permitted nutrient claims. No aggressive biohacker hype.

Third-party testing 4.0/10

No strong independent third-party certification such as NSF or USP. Quality relies primarily on manufacturer statements and HACCP/GMP-adjacent standards.

Product Description

Fairvital’s B-12 Activ Complex combines the two bioactive forms methylcobalamin and adenosylcobalamin. This is a better choice than a cheap cyanocobalamin-only product for those wanting a quality standard solution.

What We Like

  • Relevant for the target group: Particularly useful for vegans, vegetarians, and those with low B12 status
  • Active B12 forms: Methyl- and adenosylcobalamin instead of just the synthetic base form
  • Straightforward basic pick: No overcomplicated formulation — a clear, easy-to-understand product
  • Good pack size: 90 servings last three months

What We’re Missing

  • No strong third-party certification
  • Not the cheapest B12 on the market
  • No sublingual or lozenge format: Some users would find that more practical than capsules

Ingredient dossier

Vitamin B12 is essential for nerve function, DNA synthesis, and homocysteine metabolism. Deficiency is common in vegans, older adults, and metformin users and causes irreversible nerve damage.
