MTR and MTRR genetic variants, Vitamin b12 genetic variants, choosing the right form of B12 for your genetic variants

Vitamin B12, MTR & MTRR, and Methylation

There are several genes that can influence your absorption, transport, and need for vitamin B12. Some people need higher amounts of B12, and some people thrive on different forms of B12. Take a look at your genetic data to see if you should up your intake of B12.

Mushroom Intolerance: IBD, Ergothioneine and the OCTN1 Gene

Mushroom Intolerance: Ergothioneine and the OCTN1 Gene

Mushrooms contain a healthy antioxidant called ergothioneine. But for people with a SLC22A4 genetic variant, this antioxidant can be too much of a good thing, leading to intestinal problems. Check your genetic data to see if you carry this mushroom intolerance variant.

MTHFD1: Folate cycle and Choline

MTHFD1: Folate and Choline

The MTHFD1 gene encodes an enzyme in the folate cycle. Genetic variants here can indicate a greater need for choline or folate in the diet.

Creatine Synthesis, Foods high in creatine, creatine benefits

Creatine: Boosting Muscles and Increasing Brain Power

Creatine is an amino acid used in muscle tissue and the brain for energy in times of stress. Genes play a role in creatine synthesis. Find out what the research shows about creatine supplements for muscle mass and cognitive function.

Biotin Genetic Variants, Biotin deficiency symptoms, foods high in biotin

Biotin Deficiency: Genetic Reasons for Increasing Biotin

Biotin, also known as vitamin B7 or vitamin H, is a cofactor that aids in the metabolism of fats, carbohydrates, and proteins. Biotin deficiency due to diet is pretty rare, but there are genetic variants that can increase your risk for biotin deficiency or insufficiency.

Genetics and Vitamin D Levels

Vitamin D Genes

Your vitamin D levels are impacted by sun exposure and your genes. Learn more about how vitamin D is made in the body and how your genetic variants impact your levels.

Short-chain Acyl-CoA Dehydrogenase Deficiency

Short-chain Acyl-CoA Dehydrogenase Deficiency

If you have tried fasting or perhaps a ketogenic diet and felt horrible, there could be a genetic reason. You might carry a genetic mutation that causes SCADD (short-chain acyl-CoA dehydrogenase deficiency).

COMT: How to Optimize Your Supplements for Your COMT Genotype

Some supplements interact with COMT variants to impact the rate at which neurotransmitters are broken down. Check your COMT genotype and discover how this may affect your reaction to different supplements or combinations of supplements.

Caffeine sensitivity genetics, CYP1A2, ADORA2A

Caffeine Sensitivity and Your Genes

Caffeine remains the most popular ‘drug’ of choice for a large percentage of the population. Genetics determines how quickly your body processes and eliminates caffeine and whether it is likely to make you jittery or anxious.

MTHFR, Folate, and Fertility

Folate Optimization: MTHFR and Fertility

MTHFR variants affect the conversion of folate into the active form. Learn how this can affect you if you are trying to get pregnant.

CBS gene, low sulfur diet, CBS gene variants and homocysteine levels

CBS Gene Variants and Low Sulfur Diet

Some clinicians recommend a low sulfur diet for people with CBS mutations. Find out what the research shows – and why that recommendation is not backed up. (Member’s article)

Selenium and Your Genes

Selenium and Your Genes

Selenium is a trace element found in certain foods. Learn how selenium is used in the body, why it is important, and how genetic variants can make someone more susceptible to problems with a selenium-deficient diet.

MTHFR_ Going Beyond C677T and A1298C

MTHFR: Going Beyond C677T and A1298C

The MTHFR C677T and A1298C variants get a lot of press, but they do not give the whole picture of the MTHFR gene. Additional variants are impacting the functionality of the enzyme.

IgE-mediated Food Allergies, non-IgE-mediated Food Allergies

Genetics and Food Allergies

Do you have a food allergy? Discover how environmental factors and genetic susceptibility can shape individual reactions.

MTHFR variants and depression and anxiety

MTHFR, Depression, Anxiety, Symptoms and Treatment

We are all genetically unique, and a common genetic variant in the MTHFR gene causes some people to be more susceptible to having low folate levels. This article explains the research linking MTHFR variants, folate, and depression — and gives you information on how diet or supplements may help.

MTHFR Gene variants, folate, MTHFR and vaccine response, genes that impact vaccine efficacy

Vaccines and the MTHFR mutation

This article covers what the research shows about folate metabolism, MTHFR, and immune response. See what the research says.
