Ever eat a meal and get a headache afterwards out of nowhere? Or maybe it makes your brain feel slow, or gives you an upset stomach, and you have no idea why? Food sensitivity could be to blame. These sensitivities aren’t quite allergies in the sense that they’re dangerous, but their mild symptoms can absolutely affect your performance. And if you have no idea what’s causing them there’s no way to stop it.

The only way to really identify the culprit and avoid any future issues is with food sensitivity blood tests. These tests measure your body’s immune response to a wide variety of food and give you actionable information to better improve your health overall.

Vitamin D helps to maintain optimal serotonin and dopamine levels, boosts immune function, strengthens your bones, and improves your cardiovascular system. But because of our mainly indoor lifestyles, the vast majority of people have either deficient or insufficient levels. And that’s why Vitamin D supplementation is critical to health and performance.

The problem is that too much Vitamin D can build up in your system and be almost as bad as too little. That means that testing your levels to make sure that you’re supplementing with the correct dose is vital. That’s where Everlywell comes in. They’ve created an affordable at-home Vitamin D test to take out all the guesswork and make sure your body is getting exactly what it needs.

Though a part of the body that many people know little about, the thyroid plays a major part in daily wellness. Both hyperthyroidism and hypothyroidism — too much thyroid activity and too little thyroid activity, respectively — are cause for concern.

Luckily now Everlywell offers an easy at-home test kit to accurately measure four key markers for thyroid function. Find our review of that test here.
