Methyl B Complex
The science behind our ingredients
Methyl B Complex
Is this right for you?
Methyl B Complex
Is this right for you?
- 01You feel tired or foggy despite a decent diet
Low B vitamin status is a common cause of fatigue, brain fog, and low energy — and can persist with a healthy diet, especially under stress or with genetic variants.
- 02You have an MTHFR variant or methylation issues
Many people carry MTHFR variants that reduce folate processing. Methylated B vitamins are the most reliable way to support methylation regardless of genetics.
- 03You eat a plant-based or restricted diet
B12 is found primarily in animal foods, making deficiency more common in vegan and vegetarian diets. A daily methyl B complex helps fill the gap.
- 04You want to support brain and nervous system health
B vitamins are essential for nerve function, neurotransmitters, and cognitive health. Methylated forms are the most reliable way to support these systems daily.

why we’re different
Not all supplements are created equal.
At Parsley, ‘professional grade’ means every supplement is third-party tested for quality and purity, and manufactured in NSF/USP-certified, cGMP-compliant U.S. facilities that meet FDA standards.
Our clinicians know which supplements actually move the needle — and which don't. Every formula is selected for clinical evidence, optimal bioavailability, and meaningful dosing. Not what's cheapest to manufacture. What actually works.
