Brand: Pure Encapsulations · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that Pure Encapsulations Adenosyl/Hydroxy B12 Liquid is a supplement that provides vitamin B12, a nutrient essential for nerve function and red blood cell formation. However, based on the data provided, the primary ingredient with detailed information is calcium, not the B12 forms listed on the label. Data on the specific B12 ingredients in this product is not available. Our assessment is that you should verify the specific B12 dosage and form with the product label, as the available data focuses on calcium.
How it works
Think of calcium as a master regulator for your bones and muscles. It supports bone mineralization to maintain density and helps with neuromuscular relaxation, which is essential for proper muscle function and nerve signaling [NIH ODS]. While this product is marketed for B12, the data provided details calcium's mechanism, not the B12 components.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Side effects for the B12 ingredients in this product are not available from the provided data.
Our recommendation
Our recommendation is to use this product only if you have a confirmed need for supplemental B12, as data on its specific B12 ingredients is not available. Be aware that calcium supplements can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider to ensure this product is appropriate for your health needs, especially if you take any of these medications [NIH ODS].
