Phentaslim is a non-prescription fat burner. It comes from Optimum Nutra Inc. and has been designed to provide appetite suppression, boosted metabolism, and longer lasting energy. The name of the product makes it clear that it has been marketed as an alternative to Phentermine and similar prescription weight loss medications.
At the time this review was written, a one money supply of Phentaslim, containing 60 capsules, cost $59.95, plus shipping. It also came with a 30-day, money-back guarantee.
According to the supplements facts for Phentaslim, the ingredients in the formula are: Thiamin (Vitamin B1), Riboflavin (Vitamin B2), Vitamin B6, Vitamin B12, Zinc, Niacin, L-Carnitine, Raspberry Ketones, L-Tyrosine, Caffeine Anhydrous, Green Tea (4:1 extract), Guarana Seed, Panax Ginseng Root, Cayenne. Each of the formula’s ingredients have been clinically tested to determine their efficacy for weight loss.
For instance, studies have found caffeine anhydrous to be effective for weight loss as it helps to augment metabolism, increases mental focus and alertness, and can cause appetite suppression in some people. Guarana Seed is an energy booster, increases memory, alertness and mood, and also works to suppress hunger. Studies have found green tea to increase thermogenesis without increasing heart rate, as well as lower body fat, stimulate fat oxidation, and reduce blood pressure and cholesterol levels.
It was refreshing to find that while the official site for Phentaslim was clearly designed as a sales page, it still contains the complete list of ingredients, as well as provides details about its key ingredients, and provides references to the studies it mentioned. The product has also been manufactured in a 100% GMP certified facility.
The one major downside to Phentaslim, however, is that it contains multiple stimulants, including ingredients with a high caffeine content: caffeine anhydrous and guarana seed. Due to the fact that there is more than one caffeinated substance in this product, those who have sensitivities to these stimulants and anyone who ingests other stimulant foods or beverages while taking it, are at a higher risk of certain negative side effects including, but not necessarily limited to: rapid heartbeat, jitters, headache, nausea, insomnia, nervousness, anxiety, increased blood pressure, etc.
The suggested daily dosage for Phentaslim is to take 1 capsule with water 20 minutes prior to breakfast and 1 capsule with water 20 minutes before lunch. Users are cautioned not to take it after 3 pm to avoid sleep troubles. For best results, this pill is meant to be used in conjunction with regular exercise and a healthy diet plan.
It is best to consult your healthcare provider before taking Phentaslim. This is especially important if you have an existing medical condition or are currently taking other supplements or medications.
