Important Features to Consider

Iodine tinctures should have a few important features. Here’s what to consider when selecting an iodine tinctures:

  • Type of iodine tincture. To put it simply, there are two main types of iodine tinctures: those formulated to be consumed orally as a dietary supplement and those formulated to be applied topically on your skin or other surfaces as an antiseptic. It’s vital to double-check that you have selected the appropriate type of product for your purposes before heading to the checkout.
  • Micrograms per serve. One of the most important features to check is how many micrograms of iodine are contained in a single serve of dietary supplement iodine, as this will vary from product to product. The amount of micrograms will affect the recommended dosage, as we touch on next.
  • Recommended dosage. Each dietary supplement iodine product will specify a recommended dosage in drops. This will vary from product to product due to the fact that different products have different micrograms of iodine per serve. Always follow any instructions provided as well as the advice of your doctor.
  • Potency. Iodine tinctures for external use come in different potencies of iodine. For example one product may contain 2% and another will contain 10%. Check the label carefully to ensure you buy one that matches up with your needs.

Frequently Asked Questions

What is a tincture of iodine used for?

Tincture of iodine boasts a number of use cases that can help you attend to a range of health issues. Iodine can be taken as a dietary supplement to help with health problems including thyroid issues, metabolism issues, lack of energy, immune system problems, brittle hair, and weight gain. The reason iodine may help is because it plays a fundamental role in your thyroid health. If your thyroid is not in good health, you may experience the aforementioned issues.

Before you use tincture of iodine to treat these issues, we strongly advise that you speak to your doctor first.

Topical application uses of tincture of iodine include treating fungus issues (such as athlete’s foot), and disinfecting small wounds as well as scrapes and cuts. Some iodine tinctures can be used to purify water in emergency situations. Iodine formulated for external use only can be used to disinfect surfaces.

Does tincture of iodine kill fungus?

Yes, tincture of iodine can kill fungus if applied topically. It’s thanks to iodine’s antimicrobial properties that is able to kill fungus. Be sure to follow directions on each tincture of iodine. Keep in mind that you should never apply straight iodine to your skin without first diluting it! Fortunately, the way in which tincture of iodine is formulated makes it safe to use straight from the bottle.

Can iodine tincture be taken orally?

Yes, certain iodine tinctures can be taken orally, if they are made for oral consumption. Iron tinctures can either be formulated for oral consumption or topical use (application on your skin). If you want to take an iodine tincture orally, it is absolutely vital to double-check the product label and description to ensure you’re buying the appropriate type of product. Moreover, you should always follow the directions provided by the manufacturer about recommended dosage and take an appropriate which is suitable to your specific health needs and body.

How many drops of iodine should I take per day?

The amount of drops of iodine you should take per day will depend on both the iodine tincture you are using as well your specific health needs and body. We suggest consulting this fact sheet by the Office of Dietary Supplements (ODS) as well as the Mayo Clinic’s general dosing guidelines. The number of drops you should take will depend on each product, as products vary in their iodine concentrations. For example, some products will recommend 1 drop while others will recommend 3. This is why you should always read the label before use.

The reason it is critical to take the correct amount is because it is possible to take too much iodine. When in doubt about how much to take, always consult a health professional. We particularly recommend pregnant women to get the all-clear from a doctor before taking iodine. Remember, when it comes to your health, it’s always better to be safe than sorry.

In terms of using iodine topically, Mayo Clinic advises to use the iodine tincture as directed. To be clear, they do not recommend using topical iodine on deep, puncture wounds, animal bites, or serious burns. Again, when in doubt, always check with a health professional before use.
