Effective Urolithin A blend with added vitamins, third-party tested but lacks manufacturing origin details.
Balanced Urolithin A supplement with vitamins and lab certifications, though lacks origin info and has lower additive doses.
This review is from Amazon.com for product:
Inner Brightness Urolithin A Supplement 1400 MG - Non-GMO, Gluten-Free, Anti-Aging, Cellular Renewal, Muscle Strength, Endurance & Longevity Support, Liposomal Urolithin A, 60 Count
The Inner Brightness Urolithin A Supplement supplies a moderate potency of Urolithin A but also some additional ingredients, including Vitamin C, Resveratrol, and Collagen Peptides, but at lower doses. The manufacturer lists cGMP and 3rd Party Lab testing certifications which are plusses, but does not list country of manufacture, which is a minus. The product itself appears high quality with no broken capsules or leaking product in the bottle.
Overall this is a good supplement for me, as I am looking for Urolithin A and am not trying to avoid any of the other ingredients.
Vitamin Basics & Tips
Vitamin A plays a critical role in maintaining vision, immune function, and skin health. Found in foods like carrots, sweet potatoes, and spinach, it exists in two forms: preformed vitamin A (retinol) from animal sources and provitamin A carotenoids (like beta-carotene) from plants. Adults typically need 700–900 mcg daily, but excessive intake can lead to toxicity, causing dizziness or liver issues.
In skincare, vitamin A derivatives like retinol are popular for reducing wrinkles and improving texture by boosting collagen production. However, supplements should be used cautiously alongside vitamin A-rich diets to avoid overdosing. Pregnant women require special attention, as excess vitamin A may harm fetal development.
Urolithin A, though not directly related to vitamin A, is a gut-derived compound linked to cellular health and longevity. Pairing it with antioxidants like vitamin C (as seen in this supplement) may enhance overall benefits, though dosage balance remains key for efficacy.
