Potential side effects of Plexus Slim include a rash, nausea and headache. A popular weight loss product, Plexus Slim contains two active ingredients including Chromium and the Plexus Slim Blend, according to Plexus Worldwide.
The largest amount of active ingredient in Plexus Slim is Chromium with 200 micrograms present per slim pack. Chromium is a trace element that is considered safe for ingestion in doses up to 1,000 mcg for six months daily, according to WebMD. However, some report side effects like dizziness, nausea, skin irritation, headaches, mood changes and impaired thinking. Those who exceed the safe dose recommendation may be at risk of blood disorders and kidney disease.
The Plexus Slim Blend contains green coffee bean extract, garcinia cambogia extract and alpha lipoic acid. Green coffee bean extract is used in many weight loss products. The high caffeine content in the extract can cause insomnia, nervousness, restlessness, stomach upset and increased heart and breathing rate. Larger amounts of coffee may cause headaches, anxiety, tinnitus, agitation and an irregular heartbeat.
Garcinia cambogia extract is also used for weight loss and improving exercise performance. This supplement may cause headaches, nausea and digestive discomfort. Alpha lipoic acid is an antioxidant found in many foods. It can cause a rash and might lower blood sugar levels, which may be bad for people with diabetes.
