5 Warning Signs You’re Low in Vitamin D—And How to Fix It Naturally

Over 1 billion people worldwide are low in vitamin D; most have no idea. This “sunshine vitamin” does far more than just support bone health. It’s a hormone-like powerhouse tied to immunity, energy, mood, and even cancer prevention. Yet deficiency is extremely common, especially in winter, for those with darker skin or those who spend most of their time indoors.

Here are five key signs your body may be crying out for more vitamin D:

  1. Fatigue that won’t quit
    Dragging through your days? Vitamin D helps convert food into energy. Without enough, you may feel constantly tired—even after a full night’s sleep.
  2. Aches in your bones or muscles
    Vitamin D helps your body absorb calcium. When levels are low, you may feel bone, joint, or muscle pain, sometimes mistaken for fibromyalgia or arthritis.
  3. Hair thinning or hair loss
    Vitamin D plays a role in the hair growth cycle. Deficiency can lead to slower growth or shedding, and has even been linked to alopecia.
  4. Frequent illness
    Are you always catching colds? Vitamin D is critical for immune defense. If your levels are low, your body may struggle to fight off infections.
  5. Low mood or anxiety
    Low vitamin D has been linked to depression, anxiety, and seasonal affective disorder. If you’re feeling unusually blue, this may be a factor.

How to Get More Vitamin D

Sunlight: Aim for 15–20 minutes of direct sunlight daily on bare skin (without sunscreen).
Food sources: Include fatty fish (like salmon, sardines, tuna), egg yolks, liver, and vitamin D-fortified foods like dairy and plant milks.
Supplement smart: Vitamin D3 is better absorbed than D2. Look for D3 paired with K2 for proper calcium regulation. Daily intake should be around 600–800 IU, but talk to your doctor if you suspect a deficiency.

Pro tip: The only way to know for sure? Ask your doctor for a blood test. Don’t guess—test!

Ketchup Was Once Sold as a Medicine

Dr. John Cook Bennett, a rather eccentric American physician in the 1830s, was convinced that tomatoes held incredible healing powers. He believed they could purify the blood and cure a wide range of illnesses, from digestive problems to jaundice. He began selling ketchup as a concentrated form of tomato medicine, even creating “tomato pills” for convenient consumption. Bennett wasn’t shy about sharing his beliefs, publishing pamphlets and giving lectures promoting his “tomato cure.”

His claims caught on like wildfire, and soon the market was flooded with various tomato-based pills and concoctions, all promising miraculous health benefits. Unfortunately, many of these products were simply cashing in on the craze and contained little to no actual tomato. Some were just cleverly disguised laxatives. This led to a chaotic “tomato pill war,” with companies making outlandish claims and vying for customers.

However, the lack of scientific evidence to back up these claims, combined with the prevalence of fraudulent products, eventually led to the decline of the “ketchup cure” by the mid-1800s. People started to realize that ketchup wasn’t the miracle cure it was advertised to be.

Despite its failure as medicine, ketchup didn’t disappear entirely. In the late 19th century, companies like Heinz recognized its potential as a condiment. They began mass-producing and marketing ketchup, focusing on its delicious flavor and versatility rather than its supposed health benefits. 

Today, ketchup is a beloved condiment enjoyed worldwide. It’s a staple at barbecues, a perfect pairing for french fries, and a classic ingredient in many dishes. It’s quite a journey for something that was once touted as a cure-all!

Oddly, tomatoes were once considered poisonous to eat.

Tomatoes were once considered dangerous due to a combination of factors. They belong to the nightshade family, which includes some poisonous plants, and their bright, shiny appearance further fueled suspicion. 

Additionally, a misunderstanding about lead poisoning from pewter plates led people to wrongly blame tomatoes for illnesses. These factors created a fear of tomatoes that persisted for quite some time.
