EVTene
Also known as: EVTene
Overview
EVTene is presented as a proprietary or brand name for a supplement ingredient, but there is no direct peer-reviewed scientific or chemical identification for it. Based on the context of the provided research, it appears to be related to or marketed alongside vitamin E and beta-carotene, which are well-known fat-soluble antioxidants. Vitamin E is a family of compounds (tocopherols and tocotrienols) found in nuts, seeds, and vegetable oils, while beta-carotene is a provitamin A carotenoid found in colorful fruits and vegetables. These compounds are primarily used for their antioxidant properties to reduce oxidative stress and support immune function. While vitamin E and beta-carotene have been extensively studied in large randomized controlled trials and meta-analyses, the research maturity level for EVTene itself is non-existent, as no specific studies on this branded ingredient were found.
Benefits
There is no evidence-based benefit for EVTene specifically. For the related compounds, vitamin E and beta-carotene, high-quality evidence from numerous large-scale studies and meta-analyses indicates a lack of beneficial effects for chronic disease prevention and, in some cases, potential harm. Beta-carotene supplementation has not shown beneficial effects on cancer prevention or cardiovascular disease (CVD) incidence, with some studies suggesting potential harmful effects on CVD mortality. Similarly, vitamin E supplementation above the recommended dietary allowance (RDA) of 15 mg/day has been associated with a small but statistically significant increase in all-cause mortality (relative risk 1.03, 95% CI 1.00 to 1.05). While some meta-analyses suggest a minor effect of vitamin E on reducing the risk of age-related cataracts, its clinical significance is limited. No clear population-specific benefits have been consistently demonstrated, and effect sizes are generally small and often not clinically meaningful, with some findings indicating potential harm rather than benefit, even with long-term supplementation.
How it works
As there is no specific information on EVTene's mechanism of action, the explanation is based on the related compounds, vitamin E and beta-carotene. Vitamin E functions as a lipid-soluble antioxidant, primarily protecting cell membranes from oxidative damage by neutralizing free radicals. Beta-carotene, a precursor to vitamin A, also exhibits antioxidant properties. Both compounds interact primarily with oxidative stress pathways and immune function within the body. Vitamin E targets lipid peroxidation pathways, while beta-carotene can be enzymatically converted to retinol (vitamin A). Both are fat-soluble and require dietary fat for optimal absorption, influencing their bioavailability.
Side effects
There is no specific safety assessment for EVTene. However, based on extensive research on vitamin E and beta-carotene supplementation, there are significant safety concerns. Supplementation with vitamin E above the recommended dietary allowance (RDA) and beta-carotene has been associated with an increased risk of all-cause mortality in large meta-analyses. While no specific common side effects (>5%) are reported, the increased mortality risk is a critical concern. Beta-carotene supplementation is contraindicated in smokers due to an increased risk of lung cancer. Vitamin E can interact with anticoagulants and antiplatelet drugs, increasing the risk of bleeding. Therefore, caution is advised for individuals with bleeding disorders or those on blood thinners. The overall safety assessment for these related compounds suggests that supplementation, particularly at higher doses, may pose risks rather than offer benefits.
Dosage
There are no established dosing guidelines for EVTene due to a lack of specific research. For vitamin E, the recommended dietary allowance (RDA) is 15 mg/day. However, evidence from meta-analyses suggests that doses above this RDA may increase mortality risk. The upper intake level for vitamin E is 1000 mg/day, but studies indicate potential harm at much lower doses (>15 mg/day). There is no established minimum effective dose for beneficial outcomes, as consistent benefits have not been demonstrated. Long-term supplementation (e.g., over 4 years) with vitamin E and beta-carotene has not shown consistent benefits and, in some cases, has been associated with increased mortality risk. Both compounds are fat-soluble and require dietary fat for optimal absorption. No specific form-specific recommendations or required cofactors are identified for EVTene.
FAQs
Is EVTene safe?
Based on extensive research on related compounds like vitamin E and beta-carotene, high-dose supplementation may increase mortality risk. There is no specific safety data for EVTene itself.
Does EVTene prevent chronic diseases?
No strong evidence supports that EVTene, or related compounds like vitamin E and beta-carotene, prevent chronic diseases such as cancer or cardiovascular disease.
How long before effects are seen?
No consistent beneficial effects have been observed for EVTene or related compounds, even after several years of supplementation in large-scale studies.
Can EVTene be taken with other supplements?
Caution is advised, especially if taking anticoagulants, as vitamin E can increase bleeding risk. Consult a healthcare professional before combining supplements.

- https://pubmed.ncbi.nlm.nih.gov/35928292/ – This systematic review and meta-analysis of randomized controlled trials found no beneficial effect of beta-carotene supplementation on cancer prevention or cardiovascular mortality. It even suggested some evidence of increased mortality risk, with subgroup analyses confirming no protective effects across various demographics.
- https://pubmed.ncbi.nlm.nih.gov/35334942/ – This meta-analysis of randomized controlled trials concluded that beta-carotene supplementation offered no benefit for cardiovascular disease incidence. It highlighted potential harmful effects on cardiovascular mortality, with statistically significant findings.
