"Plexus is a dietary supplement company that’s best known for its weight loss products.
However, due to a lack of research and third-party testing, it’s unclear whether Plexus supplements are truly safe or effective.
The company’s suggested weight loss regimen is also extremely restrictive and doesn’t teach important skills for building long-lasting, healthy habits.
What’s more, starting at $150 per month, Plexus weight loss combos aren’t cheap.
For all of these reasons, we recommend a more realistic approach to weight loss, such as meal planning apps, healthy meal delivery services, or working with a registered dietitian."
