Guide to Buying the Best Zinc Supplements

Zinc is a micronutrient that is essential for your body. We’ll help you understand how you can spot the best zinc supplements out there with this buying guide, ensuring you get the most out of your regimen.

Doctor’s advice

First, we’ll let you in on a suggestion: make sure you go to the doctor and get your basic blood work done, at the very least. This will allow your doctor to understand the requirements of your body better. They can then recommend whether you should go for zinc supplements or not. It’s not advised to take supplements without asking a doctor’s advice first.

What would happen if your body has an excess of zinc that it doesn’t need? Zinc is normally taken to improve the immune system’s functions but if you take too much of it then it can decrease your body’s immune system’s functions as well. Therefore, you should never go beyond the daily dosage limit which is between 15-30 mg. If you are a child or a pregnant, then it’s strictly recommended to visit a doctor first. The recommended dose of zinc for children can vary, so seeking professional guidance is imperative

Type of supplement

If you’re through with the doctor’s visit, the next step is to figure out which type of supplement you should go for. Zinc is available in many forms and types such as zinc acetate, zinc picolinate, and others. How is this important? Mainly because zinc acetate is more effective against common colds/fevers whereas zinc picolinate has a better absorption rate.

Speaking strictly about forms, zinc is available in liquid doses, capsules, and lozenges. Liquid drops are a better option for those people who find it hard to swallow pills and capsules.

Company

Another important factor is to thoroughly check the company that is manufacturing or supplying zinc supplements. It’s never a good choice to opt for companies that aren’t backed by experience. High-quality supplements by trustworthy brands with renowned names are the way to go. You don’t want to compromise on your health for a few bucks.

Ingredients

With people becoming more aware of what’s good for their bodies and what isn’t, it is of utmost importance to pay attention to what goes into the supplement. Before you buy one, just see whether it is free from artificial flavors and colors. If you’re allergic to dairy, go for gluten-free zinc supplements. Some companies add preservatives and additives to their supplements which destroys the purpose of taking supplements in the first place.

People who are more sensitive about their health can go for capsules or liquid drops that have all the features in them. This means they’re free from chemicals, they’re gluten-free, soy-free, and safe to consume for most individuals out there. Usually, high-rated companies are known to provide these supplements that cater to a wide range of audiences. So, relying on cheap or unknown manufacturers will land you in hot waters. Their ingredients will be high-quality as well so you can take the supplement without an ounce of worry every single day.
