Garlic capsules have been found to offer several health benefits. They possess antimicrobial properties, which can help fight against bacteria, fungi, and viruses. Garlic supplements have also been linked to supporting heart health by potentially lowering blood pressure and cholesterol levels. Additionally, they exhibit anti-inflammatory effects, which may be beneficial for managing conditions like obesity and kidney failure. Garlic capsules may also help regulate blood sugar levels and act as antioxidants, reducing oxidative stress.

   Generally, garlic supplements containing allicin, an active compound in garlic, are associated with blood pressure benefits. A common dosage recommendation is around 600-1200 mg per day, divided into smaller doses.

The benefits of garlic capsules

Blood pressure

Garlic supplements may help lower blood pressure, especially systolic blood pressure (SBP). In one meta-analysis, garlic supplements lowered SBP by an average of 8.3 mmHg. However, the effects are usually only seen with high doses of garlic powder, and the effects of eating garlic in recipes are much less.

Cholesterol

Garlic supplements may help lower total and LDL (bad) cholesterol levels, but the effects are small and may take more than 8 weeks to appear. Garlic doesn't seem to affect HDL (good) cholesterol or triglycerides.

Heart health

Garlic may help prevent heart disease by slowing atherosclerosis and acting as a blood thinner.

Cancer

There's not much evidence that garlic supplements reduce the risk of gastric cancer. However, eating more vegetables in the garlic family may lower the risk of certain cancers, especially gastrointestinal cancers.

Interactions

Garlic can interact with some drugs, including blood thinners. People taking blood thinners should avoid garlic for one week before surgery or a dental procedure.
