This is an odorless supplement, too, which may help eliminate the bad breath or odor that can come with taking garlic every day.

Are Garlic Pills Good for You?

If you tend to stay away from garlic because of its pungent smell, you shouldn't — that's why it's so good for you. Garlic contains organosulfur compounds, which are responsible for the scent and are thought to be key to its health benefits, according to the Linus Pauling Institute (LPI).

When you crush or chop raw garlic, a compound called allicin is formed, which is responsible for many of the bulb's health benefits, according to the USDA. But the amount of this compound that's available for your body to absorb and use may vary depending on the supplement preparation, according to the LPI.

Garlic comes in many forms, including raw, powder, oil and aged garlic extract. Of these forms, powder, oil and aged garlic extract may be found in a capsule supplement.

The health benefits of garlic and garlic supplements have been researched extensively in animals, but human studies are limited. Still, based on the research to date, garlic may have a positive effect on the following conditions:

What to Look for in a Garlic Supplement

Before you pick up a bottle of garlic capsules, consider these criteria.

1. Quality

It's important to note that dietary supplements are not regulated by the FDA the same as prescription drugs before they arrive on store shelves. This means they may have ingredients not listed on the packaging, and the health claims they tout may not be supported by research.

One way to know if a supplement truly contains what it claims to is to look for a United States Pharmacopeia (USP) seal. The USP is a nonprofit organization that works to ensure the potency, purity and performance of supplements.

Currently, there are no garlic supplements that have obtained a USP seal. Your best bet is to look for a brand you trust — one you've used before, and one that follows the FDA's Good Manufacturing Practices.

2. Type of Garlic

This all comes down to personal preference. Most garlic supplements on the market today are made with an odorless formulation, which might be preferable. Some even come enhanced with parsley, which may help mask any lingering garlic scent.

According to the LPI, there are four types of garlic supplements to choose from:

  • Powdered or dehydrated garlic capsules:‌ Garlic cloves are crushed, dried and made into a powder.
  • Aged garlic extract:‌ This is raw garlic that has been stored in ethanol for up to 20 months.
  • Steam-distilled garlic oil:Garlic oil capsules have a ratio of 1 percent sulfur compounds to 99 percent vegetable oil, according to the LPI.
  • Garlic oil macerate:‌ This garlic capsule supplement consists of ground garlic in vegetable oil.

3. Cost

More expensive doesn't always mean better. You may pay a premium for extras like organic or non-GMO, but those do not guarantee a more effective garlic supplement.

Stay within your price range and make sure garlic is a good choice for you (check with your doctor) before spending more on a garlic supplement.

Who Should Not Take Garlic Supplements?

If you're taking anticoagulant medications, such as Coumadin or Warfarin, you should speak with your doctor before taking a garlic capsule. Garlic can enhance the effect of these medications, which can increase your risk of bleeding, according to the LPI.

Garlic supplements are not recommended if you're on antiretroviral medication for HIV, either. Garlic supplements can interfere with these medications and make them less effective, according to Mount Sinai.

Are There Side Effects From Garlic Supplements?

The most noticeable and unpleasant side effect of garlic supplements is "garlic breath" and possibly body odor, per the LPI.

Other reported side effects include burping, bloating and reflux, per the January 2016 ‌Integrated Blood Pressure Control‌ research.

The Bottom Line

Garlic supplements may have health benefits, but there's no guarantee you'll see the results you're looking for. More human research is needed to confirm the actual benefits and appropriate dosages of garlic supplements.

Talk to your doctor before taking garlic to ensure it won't interfere with medications you're taking or your other health goals.
