Choose antioxidant supplements element wisely
Although antioxidants are beneficial to our health, do not blindly take those supplements with no credit in order to avoid side effects. If you want to be a smart consumer, you can refer to the following Five Tips:
1. Select trustworthy brands
Refer to some authoritative survey data to select health supplements brand with good reputation so to ensure quality are up to international standards.
For example:
More than 90% of users agree that CATALO is reliable and trustworthy American Nutrition brand2
2. Natural VS Synthesis
The second step will be investigating on whether or not such supplements are extracted from natural whole foods rather than those are chemically synthetic. Generally, multi-vitamins are synthetic as the cost is lower than natural supplements, validity is also relatively long, usually sold at a lower price with higher levels of vitamin as a selling point. However, the truth is only natural vitamins contain biological flavonoids and phytonutrients which are good for health. For example:
Natural Formula |
Synthetic formula |
Vitamin A (from carrots, sweet potato extract) |
Retinol palmitate, retinyl ester |
Vitamin B1 (extracted from legumes, grains) |
Thiamine nitrate, thiamine hydrochloride |
Vitamin C (from berries, citrus extract) |
ascorbic acid |
Vitamin E (from seed, nut extract) |
DL-α-tocopherol |
3. Specify "standardized" content
"Standardization" is used to ensure that the value is not less than the concentration of active ingredients listed. It is the only important indicator to ensure standard content and consumer protection.
For example:
Marigold, calendula are raw materials of extracting lutein, but if the content of marigold are deliberately not specified but only listing out the concentration of lutein, it means that the content of lutein in the active ingredient is very low. In contrast, as indicated having "standardized 20% lutein," is a reliable labeling
4. Clinical Proven Efficacy
The fourth way is to find out whether there is clinical trial support. Empirical researches in human clinical trials are the most valuable, followed by animal, and finally cell experiments.
Examples:
Taking Mirtoselect® North European wild bilberries for four weeks, 70% of the testers can effectively improve eye fatigue, 73% improve vision, 80% improvement in symptoms caused by glare.3
5. Avoid overdose
The last way is to consume be in accordance with recommended dosage, do not judge your own personal needs and increase the amount randomly.
Examples:
For example, excessive intake of fat-soluble Vitamin A will cause late metabolism causing liver toxicity. While too much water-soluble Vitamin C can be discharged with the urine, continuous intake of excess Vitamin C causes gastrointestinal discomfort, and increase the risk of kidney stones and urinary tract stones. So no matter the vitamins are water soluble or fat soluble, we must pay attention to amount of intake.
Consume high quality and appropriate amount of antioxidant supplements can indeed help on anti-aging and disease prevention. Remember the 5 Tips when choosing health supplements so as to give you the peace of mind.
