Douglas Laboratories Vegetarian Enzyme

Our assessment

The evidence shows that Douglas Laboratories Vegetarian Enzyme is a digestive supplement, but the data provided does not list specific enzymes or dosages. The core ingredient with available data is calcium, which is listed in the product's ingredient panel. For general digestive enzyme support, this product may be helpful, but you should verify the specific enzyme types and amounts on the label.

How it works

Think of calcium as a key structural component for your bones and teeth. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. The enzymes in this product, though not specified in the data, are typically intended to help break down food components like proteins, fats, and carbohydrates for easier digestion.

Safety profile

Data not available for side effects specific to Douglas Laboratories Vegetarian Enzyme. For the ingredient calcium, FDA received 592,059 total adverse event reports across all supplements. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by checking the product label for specific enzyme types and units. For calcium, the data shows potential risks at high levels [NIH ODS]. You should not take this product with medications like antibiotics or thyroid medication without spacing them apart. If you have kidney issues, a history of heart disease, or prostate cancer concerns, consult your doctor before use. Data not available for a specific dose recommendation for this product.
