Interaction Details
There were no interactions found between Psyllium (OTC drug) and Apple Cider Vinegar. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
The use of apple cider vinegar or the amounts of ACV in supplements is unlikely to cause clinically significant drug interactions at recommended dosages.
However, it is important to be aware of potential interactions, especially with medications that lower blood glucose levels, as these interactions have been theoretically proposed, but as I've written in my analysis on individual interaction detail pages, even this interaction is unlikely to be clinically significant for most.
In terms of side effects, it is uncommon for individuals to experience any adverse effects from taking ACV, but some mild side effects, such as nausea and indigestion, have been reported. It is important to consider that these side effects could be additive if taken with other medications that cause similar symptoms.
As always, it is important to consult with a healthcare provider before starting any new supplement, including ACV, to ensure its safe and appropriate use for your specific medical situation.
Apple Cider Vinegar Overview
Apple cider vinegar, or ACV, is the fermented juice from crushed apples. ACV is typically made by crushing apples and adding yeast and bacteria to the mixture, which ferments the sugars in the apples and turns them into alcohol. This alcohol is then converted into vinegar through a second fermentation process. ACV contains pectin, vitamins, minerals, and acid in the form of acetic acid or citric acid. While it is most popularly used in salad dressings and cooking, apple cider vinegar has been used medicinally as it is thought to have antioxidant, anti-inflammatory, and antimicrobial properties, and may help to boost the immune system.
