Our assessment
The evidence shows that the ingredient in Pure Encapsulations B12 Liquid — calcium — plays a specific role in bone health and nerve function. However, based on the data provided, we cannot assess this product’s effectiveness for vitamin B12 because the key ingredient listed is calcium, not vitamin B12. Our assessment is that the data provided does not support a recommendation for this product as a B12 supplement.
How it works
Calcium supports bone mineralization, meaning it helps deposit minerals into bone tissue to maintain density. It also supports neuromuscular relaxation, which helps your muscles relax and your nerves signal properly [NIH ODS].
