Öko-Test’s Vitamin B12 Evaluation: Only 10 Out of 29 Products Recommended
The recent investigation by Öko-Test into Vitamin B12 supplements has unveiled significant concerns regarding both product quality and marketing practices. Out of the 29 products analyzed, only ten received positive evaluations, highlighting a troubling trend within the supplement industry.
Critical Findings: High Overdose Incidences
Öko-Test’s report revealed that out of the 24 dietary supplements examined, a concerning six merited recommendations, primarily due to the frequent overdosage of active ingredients. Among the top-rated items were the B12-Asmedic drops (50 µg), Vitafit effervescent tablets from Norma (25 µg), and the Vitalis ampoules from Aldi (17.5 µg). Interestingly, the Vitamin B12-Loges capsules (1000 µg) also received commendations, but they are no longer available for purchase.
Perhaps most alarming is the classification of only four of the 29 tested products as medicinal. This designation is crucial since only these type of products can effectively address clinically significant Vitamin deficiencies.
The LaVita Controversy: Misleading Health Claims
Adding to the fervor, the consumer advocacy group Foodwatch awarded the “Goldener Windbeutel 2026” negative prize to LaVita, a micronutrient concentrate. Approximately 39% of online survey participants selected LaVita as the least favorable option due to its misleading health claims.
Despite a steep price of 50 Euros per bottle (€100 per liter), LaVita promoted questionable assertions about its benefits. In response to public backlash, the company has halted advertising that refers to its product as “Saubertrank.” Other slogans like “Fit fürs Leben” are currently under legal scrutiny.
Essential B12 for At-Risk Groups
Despite critiques, the targeted intake of Vitamin B12 remains crucial for specific at-risk populations. Current meta-analyses suggest that approximately 45% of patients with Type 2 diabetes experience micronutrient deficiencies, particularly due to the diabetes medication Metformin, which inhibits Vitamin B12 absorption.
Looking ahead to 2028, mandatory nationwide screenings for micronutrient deficiencies are planned for hospitalized patients. Rare conditions, such as autoimmune gastritis (Morbus Biermer), also necessitate lifelong supplementation, often through injections. This condition affects about 2 to 5% of the population.

Integrated Supplements and Fermented Foods
Research is increasingly leaning toward holistic approaches to health. Studies indicate that regular consumption of fermented foods like yogurt, kefir, or sauerkraut can reduce mortality risk by up to 39% in stroke survivors.
Concerning osteoporosis prevention, isolated Vitamin D supplementation proves inadequate in significantly lowering fracture risks. Only when calcium and Vitamin D are combined does it appear to reduce the likelihood of hip fractures by approximately 16%. Thus, experts recommend that supplements be used purposefully and based on scientific evidence rather than haphazardly.
As consumers grow more health-conscious, it becomes imperative to stay informed about nutritional choices, particularly with Vitamin B12 supplements. Understanding individual health needs and making informed decisions can pave the way for better health outcomes.
