Vitamin A — the visionary nutrient

What your eyes, skin, hormones, and immune system all have in common — and why this ancient nutrient deserves a place at your table.

When most people hear "vitamin A," they picture carrots and eyesight — and stop there. But this fat-soluble vitamin is quietly running a much bigger show. From the integrity of your gut lining to the rhythm of your menstrual cycle, from the clarity of your skin to the health of your growing baby, vitamin A is working behind the scenes in ways that rarely get the attention they deserve.

At Wild Witch Wellness, we believe that understanding why a nutrient matters is just as important as knowing it exists. So let's go deeper.

"Far beyond eyesight, vitamin A shapes every surface the outside world touches — your skin, your gut, your lungs — and every layer of your hormonal life."

Two forms, one nutrient

Vitamin A actually comes in two distinct forms, and understanding the difference matters for how you eat and supplement.

Animal sources

Preformed Vitamin A (Retinol)

Found in liver, eggs, dairy, and fish. Ready to use by the body immediately — the most potent form.

Plant sources

Provitamin A (Beta-Carotene)

Found in orange, yellow, and leafy green vegetables. The body converts it into vitamin A as needed — gentler and harder to overdo.

What Vitamin A does for your body

Vitamin A is far more than a vision vitamin. It regulates gene expression across hundreds of pathways, meaning it's involved in how your cells behave, grow, and communicate. Here's where it shows up most:

👁️ Vision

Vitamin A is an essential component of rhodopsin, the protein in your retina that allows you to see in dim conditions. Night blindness is often one of the earliest signs of deficiency.

🛡️Immune Defense

Keeps the mucous membranes of your nose, throat, and gut intact — your body's first line of defense against infection.

✨Skin & cellular renewal

The same retinol used in skincare products? It works from the inside too. Vitamin A drives healthy cell turnover in your skin, keeping it clear and resilient. It also keeps the cells lining your gut and respiratory tract renewing properly.

🧬Gene regulation & hormone metabolism

Vitamin A binds to nuclear receptors that influence the expression of hundreds of genes — including those involved in hormone production, immune signaling, and reproductive health. This is where its depth really becomes apparent.

🫀Heart, lungs & organ development

Vitamin A plays a critical role in the normal formation and ongoing maintenance of your heart, lungs, eyes, and other organs — particularly important during fetal development.

Where to find it in food

The most nourishing approach is a food-first one. Here are the richest sources, drawing from both animal and plant kingdoms:

Food	Serving	Amount	% Daily Value	Source
Beef liver	3 oz	6,582 mcg	731	Animal
Sweet potato	1 whole, baked	1,403 mcg	156	Plant
Spinach, cooked	½ cup	573 mcg	64	Plant
Pumpkin Pie	1 slice (commercial)	488 mcg	54	Plant
Carrots, raw	½ cup	459 mcg	51	Plant
Red bell pepper	½ cup	117 mcg	13	Plant
Egg (whole)	1 large	75 mcg	8	Animal
Dried Apricots	5 apricots	63 mcg	7	Plant

• A note on liver: it's one of the most nutrient-dense foods on earth, but once or twice a month is plenty — especially for pregnant women, where large quantities can provide too much preformed vitamin A.

How much do you actually need?

Vitamin A is measured in micrograms of Retinol Activity Equivalents (mcg RAE) — a unit that accounts for the fact that your body uses retinol and beta-carotene very differently.

Here are the official daily recommendations:

Women (19–50 years) - 700mcg RAE / day

Men (19–50 years) - 900mcg RAE / day

Pregnant women - 770mcg RAE / day

Breastfeeding women - 1,300mcg RAE / day — highest need

Upper safe limit (adults, preformed only) - 3,000mcg RAE / day

Signs you might be running low

Vitamin A deficiency is uncommon in the US, but it's more prevalent than many realize — particularly in those with digestive issues, hormonal imbalances, or higher needs. Here's what to watch for:

• Night blindness

• Dry, rough skin

• Frequent infections

• Hormone irregularities

• Slow wound healing

Vitamin A & the female body

*Not so fun, fun fact: Women were largely excluded from medical research until the late 20th century, with most studies conducted on men. In 1993, the NIH Revitalization Act of 1993 officially required women to be included in federally funded clinical research. Therefore, on this page, we will ALWAYS talk about women's bodies.

This is where vitamin A becomes truly remarkable for women. It doesn't just support general health — it participates directly in the hormonal architecture of the female body, from your first period to your postpartum recovery and beyond.

Cycle Support

Vitamin A supports the corpus luteum — the temporary gland that forms after ovulation and is responsible for producing progesterone. Without enough vitamin A, the corpus luteum may underperform, leading to lower progesterone, shortened luteal phases, and worsened PMS. It also acts as a natural estrogen balancer, helping the body metabolize and clear excess estrogen.

Fertility & Conception

Vitamin A is essential for healthy egg development, ovulation, and uterine implantation. It's also involved in regulating the follicular environment where eggs mature. Deficiency has been linked to difficulty conceiving, and research shows that local retinoid concentrations within the follicle affect egg quality.

Pregnancy

Demand for vitamin A rises significantly through each trimester as it supports the development of baby's heart, eyes, lungs, and immune system. Pregnant women are actually at greater risk of deficiency than non-pregnant women — even when supplementing. The form matters here, though: high-dose preformed vitamin A (retinol) in the first trimester carries risks. Beta-carotene from food is always safe.

Postpartum & Breastfeeding

Breastfeeding women have the highest recommended intake of any group — 1,300 mcg RAE daily. Your milk is the primary source of vitamin A for your newborn, and your own stores can deplete quickly. Nourishing them back up is an often-overlooked part of postpartum recovery.

Thyroid Health

Vitamin A works closely with a transport protein that carries both vitamin A and thyroid hormones through the body. Optimal levels support the thyroid's ability to function and regulate metabolism — particularly relevant for women, who are disproportionately affected by thyroid dysfunction.

⚠️ An important note if you're pregnant

While vitamin A is essential during pregnancy, too much preformed vitamin A (retinol) in the first trimester has been linked to birth defects. Avoid high-dose retinol supplements and large amounts of liver during early pregnancy. Beta-carotene from plants is safe at any amount — your body converts only what it needs. Always review your prenatal supplement with your provider and count total intake across all sources.

🌿 The Wild Witch approach

• Eat a colorful plate — orange and green vegetables most days provide a steady, safe stream of beta-carotene.

• If you eat meat & dairy, include eggs regularly and liver occasionally for preformed vitamin A.

• If you supplement, look for a prenatal or multivitamin that uses a blend of retinyl palmitate and beta-carotene rather than high-dose retinol alone.

• Always take vitamin A-rich foods or supplements with a healthy fat — it's fat-soluble, meaning it absorbs best alongside olive oil, avocado, or a nourishing meal.

As always, the most powerful thing you can do is pay attention to your own body. These are patterns and guidelines — not prescriptions. If you suspect you're running low or want to understand your levels more precisely, a simple blood panel and a conversation with an integrative health practitioner can tell you a great deal.
