Eternal Lean from Nature’s Plus can be purchased online directly from the supplement company or through a third-party online vitamin shop. The official website does a fantastic job of listing main ingredient and providing a scanned image of the product label. Eternal Lean is not a simple weight loss supplement. This supplement contains more than 20 ingredients, many of which we come across every day, but rarely in the same supplement.

Product Features

Chromium may help the body naturally regulate blood glucose (sugar) response. The effect is often reduced cravings for sweet or sugary snacks between meals when taking with a meal.

Raspberry Ketone is the star of the weight loss world right now. There is little, if any, clinical proof raspberry ketone has a significant impact on weight loss and most studies are on mice – not humans.

Inulin is a source of fiber. Fiber slows digestion and may help reduce hunger. Fiber helps promote a healthy colon, regular bowel movements and digestion.

The SynaptaLean complex supports brain function, according to Nature’s Plus. The only ingredient of importance in the complex is the phenylalanine. Phenylalanine alters mood and may interfere with some prescription medications.

Of the remaining ingredients, green tea extract promotes metabolism and overall health. There is 200 mg per three capsules and the dieter takes one serving per day. The 200 mg is slightly lower than we’d suggest for optimal benefits, but at least the company lists the amount of green tea in the formula.

Garcinia Cambogia is on the hot seat right now due to claims of liver damage associated with products containing the ingredient.

We thought the ingredient list was interesting enough, but there is a warning on the product label that takes the cake. We are constantly warning dieters that phenylalanine is not safe for anyone with mental health issues, especially if prescription medications are being used to control symptoms. The label for Eternal Lean warns schizophrenics to consult a doctor prior to taking the supplement. The phenylalanine is a dopamine agonist, according to Nature’s Plus.

  • Some of the ingredients are unsafe for certain dieters.
  • Garcinia cambogia may be associated with negative side effects.


Eternal Lean is not the best weight loss supplement on the market and, based on the label it is not safe for people with schizophrenia. There are likely other mental disorders that could be affected by the addition of phenylalanine.
