What is Apple Cider Vinegar?
This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Apple cider vinegar (ACV) is a type of vinegar made from fermented apple juice. It has been used for centuries in cooking and medicine due to its potential health benefits. ACV contains acetic acid, vitamins, and trace elements, which contribute to its various therapeutic properties. Other names include: Cider Vinegar, Malus sylvestris, Vinagre de Manzana, Vinagre de Sidra de Manzana, Vinaigre de Cidre.
Composition and Production
Apple cider vinegar is produced through a two-step fermentation process. First, apples are crushed and combined with yeast to convert their sugars into alcohol. In the second step, bacteria are added to ferment the alcohol into acetic acid, which gives ACV its sour taste and strong odor. The final product may also contain other acids, vitamins, and minerals.
Health Benefits of Apple Cider Vinegar
Weight Management
Several studies have shown that ACV can aid in weight management. A randomized clinical trial demonstrated that ACV, when combined with a restricted calorie diet, significantly reduced body weight, BMI, hip circumference, and visceral adiposity index (VAI) in overweight or obese individuals. Additionally, it decreased plasma triglyceride and total cholesterol levels while increasing high-density lipoprotein cholesterol (HDL-C)1.
Blood Glucose Control
ACV has been found to have beneficial effects on blood glucose levels, particularly in diabetic patients. A study on type 2 diabetic patients revealed that daily consumption of ACV significantly reduced fasting blood glucose, hemoglobin A1C, and LDL cholesterol levels. The study concluded that ACV could be an effective strategy for controlling blood glucose indices and lipid profiles in diabetic patients3. Another study supported these findings, showing that ACV effectively reduced hyperglycemia in diabetic clients4.
Lipid Profile Improvement
ACV has been shown to positively impact lipid profiles. Research involving Wistar rats indicated that ACV administration led to significant reductions in triglycerides, total cholesterol, and low-density lipoprotein cholesterol levels. These findings suggest that ACV can help manage hypercholesterolemia and hypertriglyceridemia9.
Antibacterial Properties
ACV possesses antibacterial properties, which can be beneficial in various applications. For instance, a study evaluating the antibacterial effects of ACV on infected root canals of primary teeth found that ACV had acceptable antibacterial effects against E. faecalis, suggesting its potential use as an irrigant solution in dental treatments8.
Mental Health
Emerging research suggests that ACV may have antidepressant properties. An experimental study on mice indicated that ACV could improve depressive states by increasing the production of serotonin, a mood-elevating neurotransmitter. The study concluded that regular consumption of ACV might help combat depression6.

Adverse Effects of Apple Cider Vinegar
Skin Irritation and Ineffectiveness in Atopic Dermatitis
Daily soaks in 0.5% apple cider vinegar did not significantly alter the skin bacterial microbiome or reduce Staphylococcus aureus abundance in individuals with atopic dermatitis. This suggests that ACV may not be effective for skin conditions and could potentially cause skin irritation without providing benefits1.
Potential Liver Damage in Diabetic Rats
In diabetic rats, apple cider vinegar consumption was associated with increased levels of liver enzymes (AST, ALT, ALP) and bilirubin, indicating potential liver stress or damage. Although ACV modulated some liver complications, the increased enzyme levels suggest a risk of liver damage, especially in diabetic conditions4.

How has Apple Cider Vinegar Improved Patient Outcomes?
Improvement in Glycemic Control
ACV significantly reduces fasting blood glucose, HbA1C, and insulin resistance in patients with type 2 diabetes1 2 3 4 6 7.
ACV combined with metformin shows better glycemic control compared to metformin alone8.
Lipid Profile Enhancement
ACV consumption leads to a significant reduction in total cholesterol, LDL, triglycerides, and an increase in HDL levels1 3 4 5 6.
ACV helps in lowering the LDL/HDL and Chol/HDL ratios, indicating improved lipid metabolism1.
Weight Management and Anthropometric Indices
Regular intake of ACV contributes to weight loss, reduced BMI, and decreased hip-waist ratio in overweight or obese individuals4 5 6.
ACV reduces visceral adiposity index (VAI) and appetite scores, aiding in better weight management5.
Oxidative Stress and Tissue Protection
ACV reduces oxidative stress markers like malondialdehyde (MDA) and improves antioxidant capacity (DPPH) in diabetic patients2.
ACV exhibits hepatoprotective effects, reducing liver damage and improving liver function in diabetic animal models10.
Diabetic Foot Ulcer Management
ACV dressings significantly improve the healing process and reduce the severity of diabetic foot ulcers9.

Apple Cider Vinegar Mechanisms of Action
Immunomodulatory Effects
ACV enhances immune responses by increasing levels of immunoglobulins and lysozyme activity in both serum and skin mucus, as well as boosting the expression of immune-related genes and antioxidant enzymes1 4.
Metabolic and Glycemic Control
ACV has been shown to reduce body weight, BMI, visceral adiposity index, and appetite scores in overweight or obese individuals. It also improves lipid profiles by decreasing triglycerides and total cholesterol while increasing HDL cholesterol3.
Despite its known antiglycemic effects, ACV does not significantly interfere with enteral carbohydrate absorption, suggesting its antiglycemic action may involve other mechanisms such as delayed gastric emptying or enhanced peripheral glucose uptake2.
Digestive Enzyme Activity
ACV administration increases the activity of digestive enzymes such as protease, lipase, and alkaline phosphatase, which can enhance nutrient absorption and overall digestive health4.
Neurobehavioral and Antidepressant Effects
ACV has been found to attenuate neurobehavioral deficits induced by lipopolysaccharide (LPS) in mice, likely due to its ability to inhibit oxidative stress and reduce proinflammatory cytokines6.
It also shows potential antidepressant effects by increasing the production of serotonin through the metabolism of proteins into amino acids like tryptophan5.
Hepatoprotective and Antioxidant Effects
ACV exhibits hepatoprotective effects in diabetic rats by reducing serum glucose and lipid levels, and reversing histopathological changes in the liver. It also enhances antioxidant enzyme activities, suggesting a protective role against oxidative stress7 8.
Gut Microbiota Modulation
ACV can modulate the gut microbiota composition, particularly by reducing the Firmicutes/Bacteroidetes ratio, which is associated with obesity prevention and weight management9.
Skin Microbiome
Topical application of ACV does not significantly alter the skin bacterial microbiome in individuals with atopic dermatitis, indicating that its antibacterial effects may not extend to altering skin microbiota diversity10.

Common Complaints Associated with Apple Cider Vinegar Use
Insomnia as a Side Effect
Hydroxyzine has been reported to cause insomnia in a small percentage of patients. In a study on generalized anxiety disorder, 9% of patients treated with hydroxyzine reported insomnia compared to 6% in the placebo group1.
Comparative Studies with Other Hypnotics
In studies comparing Vesparax (which contains hydroxyzine) with other hypnotics like midazolam, hydroxyzine did not show significant rebound insomnia upon withdrawal, indicating it may not commonly lead to persistent insomnia issues2 3.
