NOW Garlic 5000

Our assessment

The evidence shows that NOW Garlic 5000 is a garlic supplement intended to support general wellness, but the specific data provided does not include clinical studies or detailed ingredient breakdowns for this product. Our assessment is based on the available data, which focuses on calcium, not garlic. For NOW Garlic 5000, specific mechanism of action and efficacy data are not available.

How it works

Data not available for the specific mechanism of garlic in this product. For comparison, the mineral calcium, which is not an ingredient in NOW Garlic 5000, works through bone mineralization: it supports bone density and mineral deposition, and it also supports neuromuscular relaxation and nerve signaling [NIH ODS]. This information is provided for context only, as it does not apply directly to NOW Garlic 5000.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all dietary supplements, but specific adverse event data for NOW Garlic 5000 is not available. For the unrelated ingredient calcium, side effects at high levels include 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]. These side effects are not expected from NOW Garlic 5000, as it does not contain calcium.

Our recommendation

We recommend consulting your healthcare provider before starting NOW Garlic 5000, as specific safety and efficacy data for this product are not available. If you are taking any medications, be aware that calcium supplements (not present in this product) can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For NOW Garlic 5000, follow the label instructions and monitor your individual response.
