Specific Garlic Safety Precautions
Warnings and precautions to be aware of concerning the safety of garlic include the following:
- Because garlic supplements are considered dietary supplements, they are not as closely regulated as prescription and non-prescription drugs. This means that they can be marketed without any proof that they are either safe or effective. Do not assume that just because a product is sold in the United States that it is safe or effective. Make sure to look for garlic supplements that are made by a reputable manufacturer. Your pharmacist is a good resource for information about which manufacturers are the most reputable
- Garlic can "thin" the blood, possibly increasing the risk of bleeding. If you have a bleeding disorder, do not take garlic supplements or unusually large amounts of raw or cooked garlic without checking with your healthcare provider.
- Because garlic can increase the risk of bleeding, it is a good idea to stop taking garlic supplements at least one week before any surgeries or similar procedures.
- Garlic can be irritating to the stomach. If you have an ulcer, heartburn, or GERD, garlic could make these conditions worse.
- Garlic can interact with some medications (see Garlic Drug Interactions).
- A normal intake of garlic through dietary means is probably safe for pregnant or breastfeeding women, although larger amounts of garlic supplements may not be safe (see Garlic and Pregnancy and Garlic and Breastfeeding).
