Review Summary
Phenterfein is a weight loss supplement that contains a blend of herbal extracts and vitamins similar to other products currently on the market. It is advertised as “the #1 diet pill in the world” but it is not clear who voted on this. Additionally, it is promoted as non-prescription formula and a hardcore stimulant.
Phenterfein is marketed as a natural weight-loss alternative to Phentermine, stressing that it has no similarities to the prescription drug other than aiding in weight loss. We will look at the product’s formula to see how effective it might be.
Ingredients at a Glance
Phenterfein contains Rhodiola Rosea to stimulate the nervous system, Evodiamine for its antioxidant properties, Citrus Aurantium to enhance energy, Salvia Sclarea to increase fat breakdown and caffeine to boost the metabolism. Additional vitamins and minerals are included in the formula for support.
Ingredients In Focus
Citrus Aurantium is a citrus fruit that grows in Asia, common in weight loss products because it contains synephrine, which is believed to suppress the appetite and increase energy. Synephrine affects the system similarly to ephedrine and yet does not have the same side effects associated with ephedrine.
Rhodiola Rosea is a plant that has been used in traditional medicine for stimulating the nervous system, as discussed, as well as enhancing work performance and eliminating fatigue. Additionally, the herb has been used as an antidepressant and a treatment for headaches and sleep disorders.
Evodiamine is a fruit extract that is thought to have an effect on the way food is digested and may help aid in fat loss. However, little research exists on this extract, and the studies that are available have been done only on rats.
Caffeine Anhydrous is a basic stimulant. While it may provide an energy boost prior to working out, an excessive amount is known to cause jitteriness, anxiety and may lead to insomnia for some.
Diet Lifestyle
Phenterfein is a natural weight loss supplement, marketed as an alternative to the prescription drug Phentermine, which is intended for use by severely overweight individuals. According to the product’s usage instructions, the capsules should be taken with 16 ounces of water, and should be taken two times a day. However, the manufacturer clearly states that the pills should not be taken within eight hours of going to bed, most likely due to the stimulating effects of the caffeine.
Final Thoughts
We appreciate that the company provides an herbal alternative for weight loss, as many prescription drugs have a number of negative side effects associated with them, and herbal extracts are generally safer. Another positive, this product does not contain ephedrine.
Unlike other products of comparable strength on the market, Phenterthin does not require a prescription to purchase. That means you can get pharmaceutical-grade weight loss help without having to see a doctor. Take advantage of their free trial and decide for yourself.







Hi, I'm a dietitian with experience in hundreds of weight loss programs and fad diets. When forming my list of the
Phenterfein is THE STRONGEST diet pill I have ever taken. Recommended use is 1-3 capsules twice daily. Trust me… you do NOT want to take 3 caps. It gives you too much a a caffeine buzz. And I’m no newby to stimulants. Taking 2 capsules twice daily each bottle lasts 30 days. Taking Phenterfein at this dosage is the ultimate for mood enhancement and weight loss.
Phenterfein works. Its costly at $60-$75 per bottle. But it actually works. Few if any diet pills can claim that.
