Tight is SAN's thermogenic diet formula, formulated to increase metabolic rate and fat-burning and compete with products like Lipo G, Hydroxycut and Ripped Fuel. Unlike most products in this category, Tight is a one-a-day formula, which greatly simplifies using it. Fatburners and thermogenic formulas often have complicated dosing recommendations so many customers will appreciate the one-a-day simplicity of Tight. Like most thermogenic products, Tight!® is designed to increase metabolism and optimize fat loss. Tight!® 's proprietary blend of ingredients promote fat loss and increased metabolism in several ways. Bitter orange extract (synephrine), clary sage extract (sclareolides) and guggulsterones all have been shown to increase resting metabolism, while supporting body fat breakdown and thyroid function. Green tea extract is a well-proven thermogenic - most diet formulas now include it. Yohimbe extract is a mild stimulant and is thought to mobilize body fat, thus readying it for oxidation. Vinpocetine, usually taken for brain support, is an unusual-but-beneficial ingredient in a thermogenic formula. It's included in Tight!® to support blood flow and concentration, allowing you to stay alert and focused on your training. This is a big plus since mental focus and 'drift' can be a problem during cardio or other repetitive types of exercise. Rounding out the formula is Bioperine, a patented substance that significantly enhances the absorption of the nutrients. Bioperine is an expensive addition to any formula but one of the best ways to maximize users' results. Tight!® is designed to be taken with food.
