Should You Take Apple Cider Vinegar Pills for Gut Health?

In recent times, the surge in popularity of apple cider vinegar (ACV) as a health supplement has been remarkable. Proponents claim it can improve gut health, blood sugar control, weight loss, and more. But should you take apple cider vinegar pills for these purported benefits? Here's a look at the evidence behind using ACV pills for gut health.

Advantages of Apple Cider Vinegar Pills:

Some studies suggest apple cider vinegar may support a healthy gut microbiome. The acetic acid in ACV has antimicrobial effects, which may alter gut bacteria in beneficial ways.

For example, one study gave rats with microbiome damage either water or apple cider vinegar for four weeks. The ACV group had increased beneficial bacteria like Lactobacillus and reduced harmful bacteria like Clostridium compared to controls.

Another study found acetic acid can inhibit the growth of unwanted yeasts and bacteria like E. coli. It may also enhance the growth of beneficial Bifidobacterium. Modulating gut bacteria in this way may support digestive health.

Daily Consumption of Apple Cider Vinegar Pills:

ACV tablets typically provide around 500 mg of apple cider vinegar per capsule. Following label directions, this often equates to 1-2 capsules 1-3 times per day.

So the typical dosages found in ACV pills are likely safe for daily use. However, potential side effects can include erosion of tooth enamel, throat irritation, and decreased potassium levels.

Start with a low dose. If you experience bothersome side effects, stop taking ACV pills. As with any supplement, consult your healthcare provider before taking ACV tablets regularly.

Optimal Timing for Apple Cider Vinegar Pills:

The optimal time to take ACV pills depends partially on why you’re taking them. Some research shows vinegar taken right before a high-carb meal may improve post-meal blood sugar levels.

So if you’re using ACV pills for blood sugar control, take them just before your highest carb meal. For general gut health, you can take ACV capsules anytime. But taking them with food may help minimize potential stomach upset.

If taking ACV for weight loss, ingest the pills about 15-30 minutes before meals. Some research shows vinegar consumption in the morning may enhance feelings of fullness and reduce later calorie intake.

You can experiment to find the best time of day for your needs. Just be sure to take ACV pills with a full glass of water to prevent erosion of tooth enamel.

Initial Effects of Apple Cider Vinegar Pills:

When you first begin using ACV pills, you may notice:

  • Increased feelings of fullness after taking ACV before meals
  • Less after-meal bloating
  • Improved regularity if constipation is an issue
  • Better blood sugar control
  • Changes in taste perception – foods may taste more sour
  • Some people report increased energy, appetite suppression, and modest weight loss from starting a regimen of apple cider vinegar pills. 

Potential side effects when starting ACV pills can include:

  • Nausea, especially if taken on an empty stomach
  • Tooth enamel erosion with improper use
  • Throat irritation
  • Drug interactions
  • To minimize side effects, start with a low ACV dose with food and water. Avoid brushing teeth immediately after taking ACV capsules. Throat irritation can often be avoided by taking pills with adequate water.

Apple Cider Vinegar Pills: Night vs. Morning Dosing

Few studies directly compare taking ACV pills morning vs evening. But some evidence suggests the timing may depend on your goals:

  • For blood sugar control, vinegar before high-carb meals may be most effective. This suggests taking ACV in the morning and evening for people who eat carbs throughout the day.
  • For weight loss, morning intake on an empty stomach may provide the best appetite and calorie control throughout the day.
  • If taken for general gut health, the timing likely doesn’t matter too much.

Take note of how the pills make you feel when taken at different times. You may find you tolerate ACV capsules better in the morning or evening.

Try taking some in the morning and some at night for a split dosage if needed. Listen to your body, and adjust the timing as needed.


What’s the difference between taking ACV pills versus liquid ACV?

ACV tablets contain a dehydrated, concentrated powder form of apple cider vinegar, which makes them more convenient than liquid ACV. The pills also avoid the taste issue since liquid ACV has a strong, acidic flavor. However, liquid ACV allows you to control the dosage and dilution yourself.

Are there any risks or side effects of taking ACV pills?

Some possible side effects of taking apple cider vinegar pills include irritation to the esophagus or stomach, throat burning, nausea, and erosion of tooth enamel over time. They can also interfere with certain medications. As with any supplement, check with your doctor before starting.

Do apple cider vinegar pills help with weight loss?

Yes, apple cider vinegar pills may promote weight loss. Studies show the acetic acid in apple cider vinegar can suppress appetite, boost fullness, and reduce fat storage when combined with diet and exercise.

Is it safe to take apple cider vinegar pills long-term?

Most experts consider apple cider vinegar pills safe for long-term use. It's best to take the pills with a glass of water and avoid laying down immediately after to prevent reflux.


Apple cider vinegar pills may offer gut health benefits thanks to acetic acid's antimicrobial effects. Start with a low dose and take ACV pills with food and water to minimize side effects.
