What You Should Know
Zip is a fat burner from Protein Factory. The fat burner includes metabolism boosting ingredients and ingredients for thyroid support, according to the product description. Prescription thyroid medications could increase fat burn, but there is little data supporting the same function for natural ingredients.
List of Ingredients
Acetyl-L-Tyrosine, 7-Keto DHEA, Olive Leaf Extract, Dessicated Thyroid Gland Extract, Kelp, Selenium, Molybdenum, Synephrine.
Acetyl-L-Tyrosine offers the same benefits as Tyrosine, but a smaller dose is needed to achieve the same results. This non-essential amino acid can be created in the body from phenylalanine. Tyrosine is converted to L-dopa in the body which has mood boosting benefits. Tyrosine may also be transformed into thyroid boosting elements in the body, which is why it is included in Zip.
7-Keto DHEA may promote increase muscle growth and metabolism, but the websites that claim this benefit do not list any clinical trials to support this claim. Olive Leaf Extract is a strong antioxidant, but it does not have any weight loss or fat burning benefits that we could find. Antioxidants are required, however, to fight off free radicals that increase when metabolism boosts.
Dessicated thyroid gland extract is another thyroid booster. Again, there is little to no evidence that natural supplementation of thyroid gland extract or other source of thyroid will boost thyroid function. The gland extract is often metabolized in the stomach before reaching the blood stream.
Kelp is a good source of iodine. Derived from brown algae, it is supposed to have fat burning abilities. The iodine in kelp may help to resort iodine levels in the body promoting healthy thyroid function. Selenium is important for cell growth.
Synephrine, the final ingredient, is a stimulant. It is often included in fat burners as a fat burner to replace Ephedra, but it does not have the same effects as Ephedra. Some reports have surfaced linking synephrine to increase heart rate, hypertension and irregular heart rate.
Zip sells for $23.99 per bottle. Each bottle contains 90 capsules with five capsules taken throughout the day in divided doses.
- Synephrine may increase metabolism a bit.
- Thyroid stimulating ingredients may increase fat burn if there is a thyroid problem.
- Synephrine is not a proven stimulant.
When attempting to lose weight with a fat burner, dieters want a proven supplement that increases metabolism and natural fat burn. This supplement could increase metabolism a bit, but there are potential side effects associated with the only fat burner in the supplement. A safer alternative would be a green tea and caffeine supplement that is proven to increase fat burn. Green tea and caffeine supplements should be packaged with a natural, proven appetite suppressant to counteract the increased metabolism.
