In Optiloss’s capsules, L-carnitine is an amino acid frequently found in pre-workout supplements and fat burners. Studies show it can promote cellular fat-burning, helping you maximize the effects of your weight loss routine.

Optiloss’s capsules contain garcinia cambogia, a small, pumpkin-like fruit native to areas in Southeast Asia. Over the last decade, garcinia cambogia has exploded in popularity for its purported effects on weight loss. The garcinia cambogia extract in Optiloss works by delivering a rich blend of hydroxycitric acid (HCA), which has been shown to suppress appetite, block carb absorption, and promote overall fat burning.

Optiloss’s oral supplements contain B vitamins, including vitamins B1 and B6. Many B vitamins are linked to metabolism and energy production. They help your body produce more energy at the cellular level, increasing glucose uptake and other energy sources in your cells.

Optiloss capsules contain synephrine to help with weight loss. Optiloss is a popular but controversial weight loss supplement ingredient. Studies show it works similarly to ephedra, a chemical banned by the FDA for its effects on cardiovascular health. Today, some supplements use bitter orange extract containing natural synephrine to promote weight loss. Others add synephrine directly.

Some small studies have connected honeysuckle to weight loss and fat burning. In a 2013 ResearchGate study, for example, researchers found that the anthocyanins, or natural antioxidants, within honeysuckle helped to prevent diet-induced obesity in mice.

Multiple Optiloss products contain coffee extract. For example, there’s green coffee bean extract in the Optiloss capsules and coffee oil extract in the Optiloss topical formula. Coffee is one of the most proven weight loss aids on the planet. Caffeine has been shown to boost metabolism, helping your body burn more calories at rest than you usually would. Green coffee, or unroasted coffee, is also particularly rich in chlorogenic acid, an antioxidant molecule linked to fat burning.

The Optiloss topical cream contains camelia sinensis or tea extract, and the Optiloss oral supplements, meanwhile, contain green tea extract. Many types of tea extract have been linked to weight loss, and some people use this tea daily for significant weight loss and fat-burning results. Like coffee, tea is rich in natural compounds linked to fat-burning, including caffeine and natural antioxidants. Green tea is rich in epigallocatechin gallate, or EGCG, a compound linked to fat burning and metabolism.

One of the most unique ingredients in Optiloss’s lineup of products is European horse chestnut. Formally known as Aesculus hippocastanum, the European horse chestnut is a flowering plant that can live up to 300 years. It has a long history of use in traditional medicine – particularly in parts of Greece and Albania, where the tree natively grows. Horse chestnut contains a poison called esculin and should not be eaten raw. However, when used in a skin cream, horse chestnut has well-known active effects for reducing inflammation and decreasing redness in skin issues such as rosacea, reducing dark circles, and helping the skin look more even.

Found in the Optiloss topical skin cream, bladderwrack is a plant extract packed with nutrients like iodine and antioxidants like “fucans.” Studies show these antioxidants could help trigger fat burning. Some even take bladderwrack specifically to help “brown” fat, turning white fat into brown adipose tissue. Brown fat has more mitochondria than white fat, leading to increased calorie burning.

Hedera helix, or common ivy, is a flowering plant native to many European countries. It can be found on walls, tree trunks, and fences across much of Europe and Asia. Today, some people use common ivy to help purify indoor air. Others believe it has antioxidant or anti-inflammatory effects. Some even take it for respiratory health. Common ivy is found in Optiloss’s topical skin cream, helping to promote antioxidant and anti-inflammatory effects.

The Optiloss topical formula contains Vitis vinifera fruit extract or grape seed extract. Grape seed extract contains resveratrol, a popular antioxidant in topical formulas and oral supplements. Studies show resveratrol can promote anti-aging benefits both inside and outside the body. Some use it for skin clarity, while others use it to fight wrinkles and other visible signs of aging.

Optiloss’s fat-burning skin cream uses coumarin, a plant-based flavor and fragrance that makes the cream smell better when applied to the skin.

Overall, the makers of Optiloss aim to have identified a handful of active ingredients linked to weight loss, fat burning, and overall metabolic health. Applying the skin cream or taking the oral Optiloss supplements daily allows these ingredients to go to work throughout the body to promote weight loss.
