Folate, also known as vitamin B9, is an essential nutrient crucial for various bodily functions. A deficiency in folate can lead to several symptoms, including:
Megaloblastic Anemia:
Folate deficiency can cause a type of anemia characterized by larger-than-normal red blood cells (megaloblasts) in the bone marrow. This condition leads to fatigue, weakness, and shortness of breath.
Weakness and Fatigue:
Low levels of folate can result in general weakness, tiredness, and a lack of energy. You can improve fatigue with a combination of B Vitamins and COQ10. COQ10 helps boost the mitochondria and produces energy. Click here for COQ10.
Mood Changes:
Folate is essential for the production of neurotransmitters like serotonin and dopamine. Deficiency may lead to mood changes, including depression, irritability, or anxiety. Improve mood with folate supplementation as well as amino acids. Click here for BiomeIQ’s Mood Plus.
Digestive Issues:
Some individuals with folate deficiency might experience digestive problems such as diarrhea, loss of appetite, or weight loss. Digestive enzymes can help. Click here for BiomeIQ’s Digestive enzymes which help reduce inflammation within the digestive tract.
Cognitive Impairment:
Folate plays a role in cognitive function. Inadequate levels may contribute to difficulties in concentration, memory problems, or cognitive impairment.
Developmental Issues (in pregnant women):
Folate deficiency during pregnancy can lead to neural tube defects in the developing fetus, potentially causing issues like spina bifida or anencephaly. This is why taking a methylated prenatal is essential for women with MTHFR. Find our favorite MTHFR Friendly prenatal here.
Pallor or Pale Skin:
Anemia caused by folate deficiency can lead to pale or yellowish skin color.
It’s important to note that these symptoms can also be indicative of other health conditions, so a proper diagnosis by a healthcare professional is necessary to confirm folate deficiency. A blood test measuring folate levels can help diagnose this condition accurately.
Folate is commonly found in foods like leafy green vegetables, legumes, fruits, and supplements. If someone suspects they might have a folate deficiency or are at risk, consulting with a healthcare provider is essential for proper diagnosis and treatment.

My daughter has MTHFR c1298c homogenous .
What does she need to avoid food wise and what supplements does she need if any she’s 21
Just diagnosed she also has Pots and dysautonomia.what do I need to do for her
Thanks
Stacy
How much folate for megablastic anemia?
What is the test for diagnosis of MTHFR and cost etc. Is it better to have one conducted at my Quest Diagnostic lab on via the online buckle swab?
The test tests for MTHFR A1298C and C677T. Here is the test kit: https://mthfrstore.com/products/mthfr-test-kit?_pos=1&_sid=893e177be&_ss=r It’s 149 but if you use the code: 20OFFTEST you will get 20 dollars off making it 129. There is no blood draw needed as it contains cheek swabs. Free consults are offered once test results come in to explain the results and answer questions.
DO you know which MTHFR Mutation and how many copies?
Avoid food wise: folic acid (common sources: Cookies, crackers, cereals, breads, pastas), processed foods, heavy metals (tuna from a can), pesticides. For supplements: https://mthfrstore.com/collections/mthfr-essentials-packages/products/essentials-relief-package-1 Have you had her homocysteine levels tested?
Hello ,
I was wondering if the A1298C causes AFib or heart palpitations?
The MTHFR gene (methylenetetrahydrofolate reductase) is responsible for processing folate and regulating homocysteine levels. The two most commonly studied variants are C677T and A1298C.
MTHFR A1298C and Heart Rhythm Issues
*The A1298C mutation is generally considered less impactful on homocysteine levels compared to C677T.
*However, both variants can affect methylation pathways, neurotransmitter metabolism, and vascular health.
Link to Heart Palpitations / Atrial Fibrillation (AFib)
*Elevated homocysteine, which can occur in MTHFR variants, is a known risk factor for endothelial dysfunction, clotting issues, and cardiovascular disease.
*While C677T has stronger evidence linking it to higher homocysteine and cardiovascular risk, A1298C can still contribute—especially if combined with C677T (compound heterozygous).
*Direct link to AFib: There isn’t strong clinical evidence that A1298C alone causes atrial fibrillation. However, people with MTHFR mutations may experience:
**Increased risk of arrhythmias indirectly due to elevated homocysteine, oxidative stress, and impaired nitric oxide production.
**Heart palpitations related to neurotransmitter imbalance (dopamine, serotonin, norepinephrine metabolism is influenced by methylation).
**Electrolyte imbalances (such as low magnesium), which can interact with MTHFR-related pathways and trigger palpitations.
Key Points
A1298C alone is not a direct cause of AFib, but it may increase susceptibility when combined with other risk factors: high homocysteine, poor diet, stress, electrolyte issues, or family history of arrhythmias.
If you have palpitations or suspected AFib, it’s important to check:
*Homocysteine levels
*Folate, B12, B6 status
*Electrolytes (magnesium, potassium)
*Heart evaluation (EKG, Holter monitor)
👉 Many patients with MTHFR benefit from activated B vitamins (methylfolate, methyl-B12, P5P), optimizing magnesium, and lifestyle strategies to reduce vascular stress.
