Ashwagandha Risks: What You Need to Know Before Taking It
When you hear ashwagandha, an adaptogenic herb used in Ayurveda to reduce stress and boost energy. Also known as Withania somnifera, it’s one of the most popular herbal supplements sold online and in health stores. But just because it’s natural doesn’t mean it’s safe for everyone. People take it for sleep, stamina, or anxiety—but many don’t realize it can cause serious side effects, especially if you’re on other meds or have certain health conditions.
Thyroid function, how your body controls metabolism through hormones can be affected by ashwagandha. Studies show it may increase thyroid hormone levels, which sounds good—until you have Hashimoto’s or hyperthyroidism. Then it can make things worse. Same goes for blood pressure, the force of blood pushing against artery walls. Ashwagandha can lower it. That’s fine if you’re hypertensive, but if you’re already on blood pressure meds or have low BP, you could end up dizzy, fainting, or worse.
Then there’s the drug interactions, how herbs can change how medicines work in your body. Ashwagandha doesn’t play nice with sedatives, thyroid meds, immunosuppressants, or even diabetes pills. It can make them too strong—or block them entirely. And since herbal supplements aren’t tightly regulated, you never know how much ashwagandha is actually in that capsule. Some brands contain contaminants, heavy metals, or even undisclosed pharmaceuticals.
It’s not just about what’s in the bottle. It’s about who’s taking it. Pregnant women should avoid it—there’s evidence it might trigger early labor. People with autoimmune diseases like rheumatoid arthritis or lupus should skip it too. Ashwagandha stimulates the immune system, which sounds helpful—but if your body is already attacking itself, you don’t want to feed that fire.
And here’s the thing: most people don’t talk about the long-term effects. We know short-term use is generally okay for healthy adults. But what about taking it for months or years? No one really knows. The studies are short. The users? They’re not being tracked. That’s why the ashwagandha risks are often hidden until it’s too late.
What you’ll find below aren’t just random articles. These are real, grounded pieces that connect the dots between herbal supplements, your body’s chemistry, and the hidden dangers you won’t hear about on Instagram. From how ashwagandha affects your hormones to why it might be making your anxiety worse instead of better—you’ll see the facts, not the marketing.
