Herbal supplements: what works, what’s risky, and how to use them safely
Herbal supplements are everywhere, from supermarket shelves to online stores. Some offer real benefits, others are oversold. This page helps you spot useful herbs, avoid common risks, and pick products that actually match the evidence.
Start by asking one simple question: what problem do you want to solve? That focus makes it easier to find an herb with real data behind it. For example, garlic extract (Lasuna) contains allicin and has measurable effects on blood pressure and immune support in several trials. Kefir isn’t a herb but a probiotic food with clear gut-health benefits. Other herbs, like ashwagandha, may help stress or thyroid support for some people, but the evidence and dosing vary.
How to judge effectiveness and safety
Look for standardized extracts. A label that lists a specific active compound—like “allicin 1.5%” or “ashwagandha 5% withanolides”—is better than vague herb names. Third-party testing seals (USP, NSF, ConsumerLab) mean the product contains what it claims and is free from major contaminants. Avoid products that promise miracle cures or use urgent marketing language.
Think about interactions. Garlic can increase bleeding risk when taken with blood thinners. Herbs that affect hormones or thyroid function (ashwagandha, iodine-containing mixes) can change how thyroid meds work. Probiotics like kefir can affect antibiotics and immune conditions. If you take prescription drugs—antidepressants, diabetes meds, blood thinners—check with your doctor or pharmacist before adding any herb.
Practical tips for buying and using herbs
Start with a low dose and track effects for a few weeks. Keep notes on improvements and side effects so you can judge value. Buy from reputable brands with clear labels and customer service. Prefer extracts with clinical dosing information rather than vague “proprietary blends.” If you’re pregnant, nursing, or have serious health problems, hold off until you talk to a clinician.
Quality matters more than price. Cheaper doesn’t always equal a bargain if the product has low potency or contaminants. If a supplement costs dramatically less than similar products, treat it with caution. Also check expiry dates and storage instructions—some probiotics need refrigeration or they lose potency.
