Can stimulants damage your thyroid?

I’ve seen a lot of people who have had sub-optimal thyroid hormones all their life and never known it.

→ They were often that bit heavier as a child.

→ They weren’t as naturally athletic.

→ They were more prone to infections and colds and flus.

And when the got older, they noticed their friends were thinner, and eating problems may have set in. Body image shifted due to societal perceptions, and negative thinking about their size set in. They started to eat less, or binge eat for comfort. Then yo-yo dieting became the norm, until one day they found they couldn’t lose weight anymore, or they were that exhausted they just didn’t care anymore.

Am I describing you? Maybe a close friend?

This thyroid problem is an epidemic, and our medical system is not designed to treat it until it is a progressed disease. This is why I am so passionate about spreading the word, and letting as many people know as possible that there is another solution!

Weight Loss Supplements that claim to BOOST Metabolism

Weight-loss dietary supplements contain a wide variety of ingredients. Not surprisingly, the amount of scientific information available on these ingredients varies considerably. In some cases, evidence of their purported benefits consists of limited data from animal and laboratory studies, rather than data from human clinical trials. In other cases, studies supporting a given ingredient’s use are small, of short duration, and/or of poor quality, limiting the strength of the findings.

The truth about commonly purchased weight loss supplements is that they usually contain stimulating ingredients that activate our internal stress response called the sympathetic nervous system. Typical stimulants are caffeine from coffee, guarana, kola nut, yerba maté, or other herbs. This increases levels of steroid hormones in the body such as adrenaline, noradrenaline, and cortisol.

In some people, this won’t be a problem and they may lose weight, usually needing to do exercise at the same time as taking the supplement.

However, in a hypothyroid person, they basically do nothing.

In a hypothyroid person with moderate to severe fatigue, they may even gain weight due to the extra circulating cortisol in their system!

One study showed that caffeine decreased serum TSH levels 1-6 hours after ingestion, which then decreased circulating T4 and T3. This is a REDUCTION in thyroid hormone after having caffeine! If someone with borderline low thyroid hormone increases dietary caffeine intake due to taking a weight loss supplementation, they very well could be damaging their thyroid system. Woah!

How to get Real, Organic and Lasting Weight loss

I know we all want a quick fix. You know – that magic pill that makes us shed kilos without changing a thing.

Sorry to break it to you, but that is not a thing.

Weight loss takes dedication, time and change.

However, if you have a suboptimal thyroid, it takes specialist treatment to help correct that. There is no magic over-the-counter supplement that you can buy to heal your thyroid.


Because over the counter supplements are designed to support healthy people! They only work for very mild imbalances, or people who are already healthy and want to stay that way.

This is where we can help. Naturopaths have access to higher dose and better quality supplements that are designed for therapeutic use.

They are trained how to use these supplements at high doses to correct deficiencies safely, support detoxification, work with genetic differences, adjust diet according to the individual needs to augment healing, and use botanical medicine to help balance the system.

So if weight loss is a struggle for you, maybe it’s time to get a thorough review of your hormones and health status, and start a truly individualised and holistic treatment approach to get results.
