Betatene Natural Mixed Carotenoids

Also known as: Mixed carotenoids, natural carotenoid complex, provitamin A carotenoids, β-carotene, α-carotene, lutein, lycopene, β-cryptoxanthin, Betatene Natural Mixed Carotenoids

Overview

Betatene Natural Mixed Carotenoids is a supplement derived from natural sources like algae, fruits, and vegetables, primarily composed of fat-soluble pigments such as β-carotene, α-carotene, lutein, lycopene, and β-cryptoxanthin. These carotenoids are known for their antioxidant properties and some, like β-carotene, also act as provitamin A precursors. The supplement is primarily used for antioxidant support, protecting the skin from UV damage, and potentially reducing the risk of certain cancers. It is also marketed for supporting eye and cardiovascular health. While extensive research exists on individual carotenoids, particularly β-carotene, studies specifically on mixed carotenoid complexes are moderate, with several systematic reviews and meta-analyses providing mixed results on overall health outcomes.

Benefits

Betatene Natural Mixed Carotenoids offer several evidence-based benefits. A meta-analysis indicated that carotenoid complexes significantly increase plasma antioxidant capacity, measured by FRAP (SMD=0.371) and ORAC (SMD=0.568), demonstrating moderate effect sizes. Dietary intake of carotenoids has been associated with a reduced risk of certain cancers, with β-carotene equivalents showing a 46% reduction in oral cavity cancer risk and a 57% reduction in laryngeal cancer risk in observational studies. Clinical evidence also supports the role of carotenoids in boosting skin resistance to UVB-induced erythema, thereby improving skin protection. However, pooled analyses did not find significant effects on antioxidative enzymes like SOD, CAT, or GPx. While antioxidant effects can be observed within weeks to months, cancer risk reduction is based on long-term dietary intake data. It's important to note that high-dose β-carotene supplementation in smokers has been linked to increased cardiovascular risk.

How it works

Carotenoids primarily function as antioxidants by quenching singlet oxygen and scavenging free radicals, which helps to reduce oxidative stress in the body. β-carotene, a key component, also acts as a provitamin A precursor, converting into vitamin A as needed, which is crucial for maintaining healthy vision and supporting immune function. These compounds interact with various body systems, providing photoprotection to skin cells, modulating the immune system, and potentially inhibiting the growth of cancer cells. Their known molecular targets include reactive oxygen species and lipid peroxidation pathways. As fat-soluble compounds, their absorption is enhanced by the presence of dietary fat, and their bioavailability can vary depending on the specific carotenoid type and the food matrix.

Side effects

Betatene Natural Mixed Carotenoids are generally considered safe at dietary levels. However, high-dose β-carotene supplementation has been linked to increased cardiovascular risk and mortality, particularly in smokers. The most common noticeable side effect at very high doses is carotenodermia, which is a harmless yellowing of the skin. Rare side effects include potential pro-oxidant effects, especially at very high doses in at-risk populations. There are no major drug interactions reported, but caution is advised with high-dose supplements in individuals who smoke or are at risk of lung cancer. High-dose β-carotene supplements are contraindicated in smokers due to the increased risk of lung cancer and cardiovascular mortality. Pregnant women should avoid excessive doses, and individuals with cardiovascular disease should also avoid high-dose β-carotene.

Dosage

For antioxidant effects, a minimum effective dose of carotenoid complexes is often observed at medium doses, typically equivalent to 6-15 mg/day of β-carotene. Optimal dosage ranges for mixed carotenoid supplements generally fall between 6-30 mg of total carotenoids daily. However, β-carotene doses exceeding 20 mg/day have been associated with risks in certain populations, particularly smokers. The maximum safe dose is not firmly established, but caution is strongly advised for β-carotene doses above 20 mg/day in smokers. To enhance absorption, it is recommended to take these supplements with fat-containing meals. Natural mixed carotenoids are generally preferred over synthetic single carotenoid supplements due to their broader spectrum of antioxidant effects. While no strict cofactors are required, the presence of dietary fat is crucial for optimal absorption.

FAQs

Is Betatene safe for smokers?

No, high-dose β-carotene supplementation, a primary component of Betatene, has been shown to increase cardiovascular and lung cancer risk in smokers, making it contraindicated for this group.

Does Betatene reduce cancer risk?

Dietary carotenoids are associated with a reduced risk of certain cancers. However, evidence for cancer risk reduction through supplementation is less clear and may vary by population, with some studies showing mixed results.

How quickly do benefits appear?

Improvements in antioxidant capacity can be observed within weeks to months of consistent supplementation. However, any potential reduction in cancer risk is associated with long-term dietary intake rather than short-term supplementation.

Can Betatene protect skin?

Yes, clinical studies support the role of carotenoids, including those in Betatene, in enhancing the skin's natural resistance to UV damage and reducing UVB-induced erythema (sunburn).

Higher doses (>20 mg/day) and single β-carotene supplementation were linked to increased cardiovascular mortality risk, especially in smokers. The study highlights the importance of considering specific populations and dosages when evaluating β-carotene's safety and efficacy.

However, it found no significant changes in antioxidative enzyme levels. The study suggests that mixed carotenoid complexes can effectively boost antioxidant status.
https://pubmed.ncbi.nlm.nih.gov/35334942/ – This systematic review and meta-analysis of 10 RCTs involving 182,788 participants concluded that β-carotene supplementation did not reduce cardiovascular disease incidence. Furthermore, it increased cardiovascular mortality risk, particularly in smokers. The findings emphasize the need for caution with β-carotene supplementation in at-risk groups.
