Effective but requires 3+ bottles to see clinical benefits per review.
Trustworthy Vitamin A supplement demands 3-month commitment despite 30-day supply per bottle, delaying results verification.
This review is from Amazon.com for product:
Nature Made Hair Growth Softgels with Lustriva, Biotin, Vitamin C & A, Support Healthy Hair as You Age, 30 Softgels, 30 Day Supply
While this brand is trustworthy and well known, it's a little disappointing that they give you a 30 day supply (one pill per day) while stating it takes 12 weeks to have any clinical effect so you won't actually know whether this supplement is helping until you've purchased several bottles of it
Vitamin Basics & Tips
Vitamin A plays a critical role in vision, immune function, and cellular communication. While this review focuses on supplementation logistics, it's important to note that Vitamin A exists in two primary forms: preformed Vitamin A (retinol) from animal sources like liver and dairy, and provitamin A carotenoids (like beta-carotene) from plant sources such as carrots and sweet potatoes.
The recommended daily allowance (RDA) for adults is 900 mcg RAE for men and 700 mcg RAE for women. Excessive intake (>3,000 mcg) from supplements can cause toxicity symptoms like dizziness or liver damage, unlike carotenoids from foods which pose minimal risk. Many multivitamins already include Vitamin A, making separate supplementation unnecessary unless medically advised.
Clinical timelines for Vitamin A supplements vary – while some skin/vision benefits may appear in weeks, immune or cellular effects often require months. Always consult healthcare providers to determine appropriate duration and dosage, particularly since fat-soluble vitamins accumulate in the body.
