Trans-Resveratrol vs Resveratrol.
The main distinction between Resveratrol and trans-resveratrol is that the name resveratrol refers to the common name for the nutritional supplement with polyphenols that are antioxidants, while trans-resveratrol acts as an active ingredient in the resveratrol product. In addition, Resveratrol is available in various degrees of purity. Pure trans-resveratrol contains 99% of the active ingredients known as trans-resveratrol. 
Trans-Resveratrol vs. Resveratrol are terms used to describe various naturally occurring phenols produced by certain plants due to injury or pathogen attacks. The two primary isomers are trans and cis Resveratrol. 
What is Resveratrol specifically?
Resveratrol is a natural phenol, also referred to as phytoalexin. Due to pathogen attacks or injuries, it is made by various plants such as peanuts, red grapes, and berries. Because of its antioxidant, anti-bacterial, anti-cancer, and antimicrobial characteristics are widely used as a nutritional supplement. The two geometrical forms of resveratrol are cis-resveratrol and trans-resveratrol. Due to the structural properties of trans-resveratrol, it is the most common form of Resveratrol which could cause adverse health effects. 
It is also believed that Resveratrol can positively affect cancer and heart disease. The evidence suggests that Resveratrol may lower blood pressure in the systolic region. Another theory is that the French have a lower incidence of heart disease, in contrast to their high-fat diets caused by the consumption of red wines rich in trans-resveratrol and other polyphenols. S. Renaud, in the early 1990s, came up with this question about the ‘French Paradox.' Additionally, moderation of red wine intake can reduce the risk of many common cancers, including prostate and breast cancer. 
What exactly is Trans-Resveratrol?
Trans-resveratrol supplements can be described as one of the two geometrical isomers in Resveratrol. Because of its structural qualities, it is an active ingredient in resveratrol supplements with potential health risks. Trans-resveratrol is an elongated backbone that contains two planes. Best Resveratrol supplements can have different amounts of trans-resveratrol, which is the main ingredient because it is a dietary supplement; this is why the product label may not include the exact amount of trans-resveratrol as a percentage of purity following FDA rules. Therefore, it is preferable to purchase a kind of trans-resveratrol with a purity of 99.
In addition, pure trans-resveratrol is associated with various health benefits, as mentioned previously. Other benefits include reduced arthritis, Alzheimer's, multiple sclerosis, Parkinson's, atherosclerosis, cataracts, and macular degeneration. 
Similarities between Resveratrol and Trans-Resveratrol
- Trans-resveratrol and Resveratrol are two natural compounds produced by certain plants such as red grapes and peanuts.
- Dietary supplements include these two ingredients.
- They also act as antioxidants and protect the body against oxidative damage.
- In addition, they may pose health risks associated with cancer and heart disease.
The Difference between Resveratrol and Trans-Resveratrol
Pure Resveratrol is a compound with antioxidant properties. It is found in certain plants as well as in red wine. Trans-resveratrol is a polyphenolic phytoalexin in numerous plants, including grapes, with anti-inflammatory, antioxidant, and anti-cancer properties. Thus, this is the main distinction between Resveratrol and Trans-Resveratrol.
Additionally, while Resveratrol can be described as an organic phenol produced in plants, trans-resveratrol can be one of two resveratrol isomers.
Resveratrol is the generic product term for a dietary supplement, while trans-resveratrol is the main ingredient in the supplements containing Resveratrol. This makes the two more distinctive.
In simple terms, best resveratrol supplements are the natural phenolic compound produced by specific plants. It can be found in two different isomers: cis and trans-resveratrol. In addition, Resveratrol is a dietary supplement because of its health benefits, such as antioxidant and anti-cancer properties. Trans-resveratrol, however, is the active ingredient of these nutritional supplements. Thus, the main distinction in trans-resveratrol is its structural and functional relationship.
