Support energy with rapid absorption liquid riboflavin, studied in the context of migraine
A liquid vitamin B2 providing 1.6mg of riboflavin as riboflavin 5 phosphate (R5P) per 10 drop serving in a purified water base with citric acid. R5P is the active coenzyme form of vitamin B2 that participates directly in flavocoenzyme reactions without requiring conversion. The liquid format provides a lower dose per serving than the capsules (1.6mg vs 47.5mg), making it suitable for those who need gentle B2 supplementation, children, or those who have difficulty swallowing capsules.
Riboflavin 5 phosphate supports the MTHFR enzyme (methylation), glutathione reductase (antioxidant recycling), the electron transport chain (energy production) and the metabolism of vitamins B6 and folate to their active forms. The citric acid in the formulation stabilises the R5P in solution. The bottle provides 138 servings per 100ml.
Key benefits:
- Rapid absorption for energy support
- Studied for migraine with regular use
- Liquid form for fast uptake

Purified Water, Riboflavin 5 Phosphate, Citric acid.
1 serving = 10 drops | 138 servings per 100ml
Directions for use:
Take 10 drops per day in water with food.
The drops can be added to a glass of water, juice or taken directly. This liquid format provides a maintenance level dose of active B2. For those requiring beneficial B2 doses (such as for migraine prevention or intensive methylation support), the capsule form at 47.5mg per capsule is more practical. The liquid is best suited for daily maintenance, sensitive individuals or as part of a broader liquid supplement routine.
