We use the scientifically advanced 5-MTHF Quatrefolic Acid developed by Gnosis. Each bottle contains 60 capsules, your order should last you about 2 months - excellent value for your money! - ★ 4th generation activated folate ★ Quatrefolic Acid is the 4th level of development in folate supplements. It is stable, pure, and better absorbed than other 5-MTHF because it's bound to glucosamine instead of calcium. - ★ Quatrefolic acid ★ Activated folate goes by a lot of names and can be quite confusing. Our supplement is Quatrefolic Acid, a trademarked supplement 5-MTHF. It is also referred to as 6 (S)-L-MTHF also known as L-5, and chemically similar to metafolin or l-methylfolate calcium except the methylfolate is bound to glucosamine (non shellfish derived) instead of calcium. So if you have been told to look for any of these, you are in the right place. - ★ High Strength ★ Each vegetarian capsule contains 5mg of activated folic acid. Folate supplementation contributes to the reduction of tiredness, normal homocysteine metabolism, normal psychological and immune system function, and increases maternal folate status which reduces the risk of neural tube defects in babies. - ★ Your health is our priority ★ Independent third-party testing, available upon request, confirms the purity, safety, and potency of our products. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075C7M9HJ | | Age Range Description | Adult | | Allergen Information | Contains: Egg Free, Fish Free, Soy Free | | Benefits | Supports heart health, healthy conception and fetal development | | Best Sellers Rank | 22,841 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 43 in Vitamin B9 (Folic-Acid) Supplements | | Brand | Intelligent Labs | | Brand Name | Intelligent Labs | | Container Type | Bottle | | Country Of Origin | USA | | Customer Reviews | 4.6 out of 5 stars 786 Reviews | | Diet Type | Gluten Free, Vegetarian | | Dosage Form | Capsule | | Flavour | Unflavoured | | Item Form | Capsule | | Item Highlight | Contributes to maternal tissue growth & blood formation.

This bottle includes doses of 5-MTHF which are 1mg in size. Usually your doctor will suggest starting with a small dose, then increasing it over time whilst being monitored. **Q: What are potential side effects?** A: Side effects may include irritability, acne, palpitations, sore muscles, achy joints, rash, nausea, and headaches. If you experience these, please speak with your doctor. You may need to reduce your dose or number of days to take it. **Q: How do I know if I have a folate deficiency?** A: Folate deficiency is hard to self-diagnose as symptoms overlap with other conditions. Consult a doctor for tests. However, symptoms include anemia, tiredness, gray hair, irritability, breathlessness, mouth sores, and birth defects in your baby. **Q: How should I store my 5-MTHF supplement?** A: We use opaque black bottles to keep all light out. But it will help greatly if you keep your bottle in a cool, dark spot. When exposed to heat or light, this nutrient is quickly broken down and made inactive. **Q: Why was this product changed from 5mg to 1mg?** A: We actually sell two different strengths of 5-MTHF (1mg and 5mg). This is the 1mg version. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by R***S on 31 August 2026* Received with thanks ### ⭐⭐⭐⭐⭐ Vitamin *by V***Y on 28 February 2026* This really supports B9 in my body and the folate.
