Vitamin A In Gelagen

What The Evidence Actually Shows

The topical evidence is enormous and it is the strongest in all of cosmetic dermatology: prescription retinoids have decades of trial data behind them for photoageing, texture and acne. The oral picture is different and needs stating carefully. Correcting a genuine vitamin A deficiency transforms skin. Taking extra vitamin A when your intake is already adequate has not been shown to reproduce what topical retinoids do, and anyone implying that a vitamin A gummy is an oral retinol treatment is misleading you. It supports the process. It is not a retinoid prescription in sweet form.

Where Else You Get Vitamin A

Liver is by far the richest source, so rich that it is possible to overdo it. Sweet potato, carrots, spinach, kale, butternut squash, eggs and dairy supply the rest, mostly as beta-carotene in the plant cases. Beta-carotene is worth knowing about because the body converts only what it needs, which makes plant sources essentially impossible to overdo.

Vitamin A: What To Watch

This is the ingredient on this label with a genuine upper limit and it deserves reading properly. Vitamin A is fat soluble and stored rather than excreted, so intake accumulates. High intake over time can cause headaches, blurred vision, bone and joint pain and liver problems. Most importantly: high vitamin A intake during pregnancy is associated with birth defects, which is exactly why prenatal vitamins are formulated the way they are. Anyone pregnant, breastfeeding or trying to conceive should speak to a doctor before taking any vitamin A supplement. So should anyone using a prescription retinoid, because those are vitamin A derivatives and what matters is the total. So should anyone taking a multivitamin alongside this, for the same reason.

What Vitamin A Is Not

Retinol on a face cream and vitamin A in a supplement are chemically related and practically very different. The cream acts where you put it. The supplement acts everywhere and accumulates. Beta-carotene is a third thing again: a precursor the body converts on demand, which is why you cannot overdose on carrots but can on liver.
