Double Wood Methylated Multivitamin Review 2026: Worth the Price?
Checks out. — Mostly Legit
-
"Methylated forms bypass MTHFR conversion issues"
L-5-MTHF and methylcobalamin skip the MTHFR enzyme step. Folate knowledge base confirms this advantage is real.
-
"Third-party tested for identity, potency, and contaminants"
Double Wood links a live COA and third-party test PDF directly on the product page — verifiable by any buyer.
-
"Called a 'Multivitamin' on the label"
Contains only 6 B-vitamins and TMG. No vitamin D, A, C, E, or any minerals. The FAQ admits this directly.
-
"Dibencozide supports cognitive function"
The only human study on dibencozide is from 1977 in post-surgical patients. No modern cognitive trial exists.

Consumer advice
If you have a confirmed MTHFR variant, or you've noticed you feel better on methylated B vitamins versus standard forms, this is a solid, fairly priced option. Third-party testing and transparent COA links are genuine positives. Just don't mistake it for a complete multivitamin — you'll still need vitamin D, magnesium, and other minerals from diet or separate supplements. The subscription saves 20% and is described as flexible, which is reasonable. If you want a direct comparison, Thorne Basic B ($20 for 60 caps) and Jarrow B-Right ($18 for 100 caps) cover similar ground at comparable or lower prices. If you don't have MTHFR or a known B12 absorption issue, a standard B-complex or quality multivitamin will serve most people just as well for less.

Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Riboflavin
High riboflavin intakes from food have no observable toxicity, and the FNB set no upper limit because adverse effects from high intakes haven't been reported. The FNB still urges caution about excessive amounts, since limited data don't rule out adverse effects.
Serious risks
- Food intakes many times the RDA show no observable toxicity; the source suggests limited solubility and absorption may explain this.
- Limited data on adverse effects don't mean high intakes are harmless, and the FNB urges caution with excessive amounts.
Medication interactions
- Riboflavin is not known to have clinically relevant interactions with medications.
Source: NIH Office of Dietary Supplements, Riboflavin: Fact Sheet for Health Professionals
Vitamin B12
The source says vitamin B12 has no tolerable upper intake level because of its low potential for toxicity, and it is generally considered safe even at large doses. Some medications can affect B12 levels, and supplements may interact with certain medications.
Serious risks
- The Food and Nutrition Board set no upper limit for B12 because its potential for toxicity is low.
Avoid or ask a doctor first if
- People who regularly take certain medications are told to talk with their health care providers about their B12 status.
Medication interactions
- B12 supplements may interact with some medications. Gastric acid inhibitors and metformin may affect B12 levels.
- Several types of medications might adversely affect B12 levels.
