Hippocrates used it to disinfect wounds some 2,000 years ago. Besides this, it may also be used for reducing weight, treating skin infections, managing blood sugar level, and reducing serum cholesterol.
Apple cider vinegar has a strong taste and smell. People who find drinking difficult due to its taste may find apple cider vinegar capsules helpful. They have vinegar in powder form and may produce the same effects as the liquid vinegar does.
Below are the scientifically proven health benefits of apple cider vinegar. They indicate how the supplement may also help you boost your health.
What is apple cider vinegar?
Apple cider vinegar is the apple juice that has been fermented two times. Initially, apples are crushed and mixed with yeast and sugar. Yeast and natural bacteria ferment the apple and convert its juice into alcohol. During the second fermentation process, alcohol is converted into acetic acid which is actually the apple cider vinegar.
You can find it in the market in two forms; pasteurized apple cider vinegar and unpasteurized apple cider vinegar. The pasteurized form lacks intact enzymes while the unpasteurized form is raw and contains natural bacteria and yeast. They give it a cloudy appearance and are called “the mother.”
It has many culinary applications but people have also been using it as a folk remedy for years. It lasts for a long time and there is no need to refrigerate it. Apple cider vinegar has 5% acidity and its smell is very strong.  People drink it due to its numerous health benefits. However, you can also have an apple cider vinegar supplement if you do not like its strong smell and taste. Its supplements come in different forms such as apple cider vinegar capsules and pills, etc.
Nutritional value of apple cider vinegar

Apple cider vinegar is beneficial for people looking for weight loss ways. There can be different reasons how it helps with weight loss. One of them is that eating or drinking it can make you feel full. It means you will eat less than you usually do which may result in weight loss.

In another human-based study, 175 obese people took apple cider vinegar for three months. At the end of the research, they were found to have less body weight and body fat mass.

Apple Cider Vinegar may help manage type 2 diabetes
Type 2 diabetes is a health condition in which either your body produces an insufficient amount of insulin or your body cells become resistant to insulin. Several human-based studies prove that apple cider vinegar can help manage the blood sugar level in healthy as well as diabetic people.
Healthy people can also enjoy the benefits of keeping their blood sugar level normal. Experts believe that the intake of higher sugar can lead to chronic disease including diabetes. The best way to maintain sugar is by decreasing the intake of sugar and eating fewer carbs. If you still fail to manage sugar, then the apple cider vinegar supplement may help.

The common risk factors are high cholesterol levels, high blood pressure for longer durations, and the formation of blood clots in arteries.
Some studies prove that taking apple cider vinegar may help improve heart risks. Most of these studies were conducted on lab animals and not on humans. Therefore, it is yet not clear how effective apple cider vinegar is for the human heart.
One study that was conducted on rats found that vinegar reduces high blood pressure.  As mentioned above high blood pressure is one of the risk factors of heart diseases, so taking the apple cider supplement could help the person keep the blood pressure normal.
Another animal study showed that vinegar reduced serum triglyceride and cholesterol level in rats that ate a high-cholesterol diet.  These animal studies show vinegar is good for improving heart risk factors in rats. The same cannot be said about humans unless more experiments are not performed.

Some people suffering from skin conditions like acne and eczema add diluted apple cider vinegar in their face wash. Since vinegar has anti-bacterial properties, it may help with reducing eczema flare-ups and acne. However, undiluted vinegar should not be applied directly to the skin, especially if your skin is already damaged. It may make the condition worse.
