But just when you thought the issue had been put to bed (seriously, just put it on a salad , people!), ACV pills-dietary supplements containing dehydrated apple cider vinegar-turned up, and reignited all the same questions: Can this kind of ACV help with weight loss? Is it safe? And should I try it?
Totally valid-but before you shell out for a month's supply of the supplements, here are a few things you should know about using ACV in pill form for weight loss.
What exactly are ACV pills?
You know how even taking a sip of apple cider vinegar feels like ingesting pure acid? Side-stepping that is the idea behind ACV pills-the vinegar is dehydrated and put into tablet or capsule form. By taking them, you can allegedly receive all the health benefits (sorry, "health benefits") of drinking ACV without burning your esophagus.
It's a good idea in theory-"Because vinegar is acidic, some people dont tolerate it all that well," Leslie Bonci, R.D., the owner of Active Eating Advice , previously told Women's Health. She adds that the vinegar can be especially irritating for those prone to stomachaches or digestive issues like inflammatory bowel disease.
What are the supposed benefits of apple cider vinegar pills?
According to Vanessa Rissetto, R.D. , a New Jersey-based nutritionist, it's the acetic acid in ACV that makes people believe it can help drop pounds, and this small Japanese study showed that ACV has potential weight management benefits and may lower your risk of heart disease by lowering triglyceride levels. Other studies have linked ACV to potential blood sugar control and diabetes management , and this rat study found that ACV may lower cholesterol . Still, the fact that most ACV research has been done on animals (like this rat study , that found ACV lowered blood sugar and insulin levels) or in very small groups of people, show that we don't really have a solid basis for any health-related claims. Whether you're popping pills or chugging the stuff, it's not likely to make a huge difference in your weight or health.
Okay, so ACV pills probably don't have any real benefits-but are they safe?
Because ingesting ACV in liquid form is generally considered safe (minus irritation and even nutritional deficiencies if you take it too far), people may assume that taking ACV pills is equally harmless and simply more convenient. But none of the (small, inconclusive) studies that have been done on apple cider vinegar have studied the pills-only the liquid. So, really, no one knows if they're safe for sure.
Additionally, taking any kind of supplement is considered a buyer beware situation, says Rissetto, and ACV pills are no different.
Supplements aren't regulated by the FDA, so you never actually know what you're getting in them, she explains. They may say there is apple cider vinegar in there, but research has shown that with supplements often it's not the exact amounts, or even what they claim to be providing.
What are the potential side effects of apple cider vinegar pills?
Frances Largeman-Roth, R.D.N. , author of Eating in Color , warns that while she wouldnt really recommend ACV pills for anyone, there may be actual risks for certain groups of people: Diabetics should absolutely avoid [them], as they may lower their blood sugar levels, and women who are pregnant or breastfeeding-or anyone under a doctors supervision-should also steer clear.
ACV pills really just aren't worth it. One study found that people who consumed a drink with 25 grams of apple cider vinegar with breakfast felt significantly more nauseous than people who didn't. And another case study found that ACV pills could potentially lower your potassium levels, which is not a good thing.
Still curious about ACV pills? At least keep this in mind:
It's tempting as hell to believe that losing weight may be as simple as popping a few supplements, but sorry, no.
There's no magic pill for weight loss...if there were, we would be a world of thin people! says Rissetto. As for ACV pills, more human studies are needed to understand how and if they work for maximum efficacy.
Largeman-Roth agrees, calling ACV pills a waste of money, at the very least. A 16-oz bottle of organic apple cider vinegar is just $4.99, while a bottle of 60 pills is between $16 and $18, she says. If youre a healthy individual who wants to see if apple cider vinegar helps you in any way, Id suggest going with the actual vinegar. You can use it in a salad dressing or blend it into a smoothie.
