We Focus on Where Symptoms Start

The AFIL tests and products address the root causes of symptoms, supporting cellular health and microbiome balance for lasting vitality.
Insights for Digestive Health

Your gut is more than just a digestive system—it’s the foundation of your overall well-being. When your digestion is out of balance, it can manifest in ways you might not expect, from bloating and fatigue to brain fog and skin issues. Understanding how your body processes food is key to unlocking better health, and that’s where we come in.

Our cutting-edge testing analyzes your body’s reactions to 1,000+ food and nutrient markers, helping you identify intolerances, deficiencies, and imbalances that may be affecting your digestion. Whether it’s a sensitivity to dairy, gluten, or other common triggers, our comprehensive insights empower you to make informed dietary choices that support gut harmony.

Insights for Energy & Performance

Ever feel drained, sluggish, or stuck in a cycle of exhaustion? Your energy levels aren’t just about sleep or caffeine—they’re about how well your body processes nutrients and fuels itself. Our premium tests help you uncover the hidden factors affecting your energy and performance by analyzing 1,000+ food and nutrient markers.

From food sensitivities that cause inflammation to vitamin deficiencies that impact endurance, small imbalances can have a big effect on your body’s ability to sustain energy and recover efficiently. Whether you're an athlete striving for peak performance, a busy professional fighting brain fog, or simply looking for more vitality, the right insights can help you fuel your body smarter.

Insights for Brain Health & Mood

Your brain is the control center of your body, and when it’s out of balance, everything feels off—foggy thinking, mood swings, anxiety, and lack of focus can all be signs that your body isn’t getting what it needs. Let’s help you uncover the hidden connections between your diet, nutrient levels, and cognitive well-being by analyzing 1,000+ food and nutrient markers.

Food sensitivities, vitamin deficiencies, and gut imbalances can directly impact neurotransmitters that regulate mood and mental clarity. If your brain isn’t getting the right fuel, it can lead to low energy, stress, and difficulty concentrating.

With personalized insights, you can optimize your nutrition to support mental sharpness, emotional balance, and long-term brain health. No more guesswork—just science-backed solutions for a clearer mind and a better mood.

Insights for Immune Health

Your immune system is your body’s first line of defense, but did you know that food sensitivities, nutrient deficiencies, and gut imbalances can weaken it? Our premium test kits are designed to help you uncover what’s supporting—or disrupting—your immune health.

When your body reacts negatively to certain foods or lacks essential vitamins and minerals, it can lead to chronic inflammation, fatigue, and frequent illnesses. By identifying these hidden triggers, you can strengthen your immune system naturally and build long-term resilience.

With personalized insights, you’ll know exactly which foods nourish your body and which ones may be working against you. No more unnecessary supplements or trial-and-error diets—just science-backed data to help you feel stronger, healthier, and more energized.

Insights for Weight & Metabolic Health

Struggling with weight loss, stubborn belly fat, or sluggish metabolism? It’s not just about calories—it’s about how your body processes and responds to food. Food sensitivities, vitamin deficiencies, and gut imbalances can slow digestion, trigger inflammation, and make weight management more challenging. If your body isn’t metabolizing nutrients efficiently, it can lead to unexplained weight gain, energy crashes, and difficulty shedding excess fat.

By identifying the foods and nutrients that work best for your body, you can optimize your metabolism, improve digestion, and support sustainable weight management. No more fad diets or guesswork—just science-backed insights to help you achieve your health goals.

Your metabolism is unique—fuel it the right way.

Insights for Sleep Quality

Struggling with restless nights, groggy mornings, or constant fatigue? Sleep isn’t just about how long you rest—it’s about how well your body restores itself. Food sensitivities, vitamin deficiencies, and gut imbalances can disrupt your body's ability to produce key sleep-regulating hormones like melatonin and serotonin. If your body isn’t properly fueled, it can lead to trouble falling asleep, frequent waking, and poor sleep cycles.

With personalized insights, you can identify the foods and nutrients that support deep, restorative sleep—helping you wake up refreshed, energized, and ready to take on the day. No more tossing and turning—just science-backed data to help you sleep soundly.

Better sleep starts with better understanding.

Insights for Heart Health

Your heart does more than keep you moving—it’s the foundation of your overall well-being. But did you know that food sensitivities, nutrient deficiencies, and inflammation can impact cardiovascular health? 

Certain foods can trigger inflammation, affect blood pressure, and disrupt cholesterol levels, making it harder for your heart to function optimally. If your body isn’t getting the right nutrients, it can lead to fatigue, poor circulation, and an increased risk of heart-related issues.

With personalized insights, you’ll know which foods support your heart and which may work against it. No more guesswork—just science-backed data to help you optimize your diet, reduce inflammation, and protect your heart in the long run.

Frequently Asked Questions

Find quick answers to your questions and get clarity on everything you need to know about our tests, process, and results.

Food sensitivity tests are designed to identify specific foods or ingredients that may be causing adverse reactions in individuals. Food sensitivity tests aim to identify triggers for symptoms like gastrointestinal issues, skin problems, headaches, and other non-allergic reactions.

Sensitivity tests are unique in that they analyze the relationship between input variables and output outcomes, allowing for scenario exploration, risk assessment, and decision-making.

We test hair as we found it to be the most robust, stable and non-invasive method of identifying intolerances, deficiencies and imbalances for our clients. It's quick and easy to start and our results turn around time is one of the fastest on the market.

Don't worry! Your hair sample is tested at the deepest cellular level. Color, treatments or bleach will not affect the validity of your test results.

Please make sure hair is clean from hair products such as hair gel or hair spray, and metallic products. Shampoo and conditioner is fine to clean the hair.

No hair, no problem! We will accept facial or body hair. We require 10 strands of hair at least 0.5 inches in length.

Where hair is shorter, provide 20 strands. Hair must be clean and free of products and metal products.

 If you're considering eliminating certain foods based on the test results, you might want to try eliminating those foods for a short period, such as a few weeks, whereas we recommend 12 weeks. During this time, monitor your symptoms and overall well-being.

Our tests cannot detect the presence of allergies. Allergies test the immune system and IgG and IgE antibodies. To test for allergies, a blood sample must be drawn. We do not require a blood sample to conduct our testing, and therefore our testing methodology would be incapable of testing for allergies.

If you require allergy testing or advice, please consult with your healthcare provider or medical professional.

Yes, absolutely, the test is suitable for all the family. Please note that children under 6 may rapidly change in intolerances, imbalances, and deficits.
