Vitamin B2 (Riboflavin) — Low-Dose, Non-Methylated
Vitamin B2 (riboflavin) helps your body produce cellular energy and is required to activate other B vitamins — including B6, folate, and B3 — so your methylation pathway can actually run. It also plays a key role in recycling glutathione, one of your body’s most important antioxidants. But most B2 supplements on the market come in extremely high doses — too high for most people, and especially for those with MTHFR and slow COMT (about 1 in 3 adults).
This is the right B2 for you if:
- You have MTHFR, slow COMT, or you’ve been told you’re “methyl-sensitive”
- You’ve reacted badly to standard B-complexes or methylated B’s
- You want a clean, low-dose riboflavin you can actually tolerate
- You’re building a stack and need a B2 that won’t overload your system
- You’re perimenopausal or postmenopausal and your tolerance to supplements isn’t what it used to be
- You’ve been dismissed by doctors who told you your B’s are “fine” even though you don’t feel fine
This probably isn’t the right B2 for you if:
- You’re looking for mega-dose riboflavin (400mg) for migraine prevention
- You want a stimulant-style energy boost
- You believe “more is better” when it comes to vitamins
What’s inside:
A gentle, bioavailable form of riboflavin at a dose your body can actually use — not a dose designed to spike bloodwork or turn your urine neon yellow. Just the amount your methylation pathway, energy production, and antioxidant system actually need to run well.
No methylated forms. No fillers. No mega-doses. No extras your body has to work to clear.
There is a lot of misinformation in the supplement world. Our products at Herb-Science aren’t for everyone and we don’t try to cover that up to make a sale. After following the wrong advice for years and not getting better, I designed products for myself, which happens to fit 1 in 3 people – Learn more here

Take 1 full dropper (16 drops) daily, preferably in the morning or with a meal.
For best absorption, hold the drops under your tongue for 20–30 seconds before swallowing.
You can also mix it into a small amount of water if you prefer.
Since Vitamin B2 is water-soluble and doesn’t store much in the body, consistent daily use is important for maintaining healthy levels.
Yes, you can! A full serving is 16 drops, but you can easily take fewer drops if you’d like a lower dose. Each vitamin is evenly distributed in the liquid, so the dose is proportional to the number of drops you take.
Vitamin B2 (Riboflavin): 0.406 mg per drop (6.5 mg per 16 drops)
Many vitamin companies put very high amounts into their formulas — often far more than your body can actually use. We take a different approach. Our formulas are designed to give you the optimal dose your body can absorb and use effectively, not just the highest number on the label.
Because our vitamins are in a liquid form, they’re easier for your body to absorb compared to tablets or capsules. That means you don’t need as high of a dose to get the same — or even better — benefits.
Plus, our doses are carefully set to match what clinical studies show is both safe and effective for long-term use. You get the nutrition you need without overwhelming your system.
Vitamin B2 plays a vital role in your overall health, supporting:
✅ Energy production — helps convert the food you eat into usable energy
✅ Antioxidant defense — supports protection against cellular damage
✅ Healthy skin and eyes — helps maintain clear vision and strong, vibrant skin
✅ Brain and nerve health — important for nervous system function and cognitive clarity
✅ Cell growth and repair — essential for tissue maintenance and recovery
Without enough B2, people can experience fatigue, dry or cracked skin, sensitivity to light, and slower healing.
Our Liquid B2 Drops are ideal for:
People with low energy, brain fog, or fatigue
Those looking to support healthy skin, hair, and eye health
Athletes or active individuals with higher metabolic demands
Vegetarians and vegans (plant-based diets can sometimes lack B2-rich foods)
Adults over 40 who want better antioxidant support and cell protection
Because B2 is water-soluble, it’s safe for daily use, and important for anyone wanting to maintain optimal energy and vitality.
Riboflavin (Vitamin B2) used in supplements is a biosynthetic form of the natural vitamin.
It’s not directly extracted from plants, animals, or foods — it’s produced through microbial fermentation using yeast or specialized bacteria in a controlled lab environment.
Here’s the basic process:
Specific microorganisms (like Ashbya gossypii or genetically optimized Bacillus subtilis) are cultured in large fermentation tanks.
These microorganisms naturally produce riboflavin as part of their metabolism.
The riboflavin they produce is harvested, purified, and dried into a stable, concentrated form — ready for supplement use.
✅ The final riboflavin product is pure, lab-created, vegan-friendly, and free from animal ingredients, because it’s grown through microbial fermentation and refined for potency and safety.
🧠 Quick Important Points:
It is NOT made from petroleum, coal, or animal organs (common myths online).
It’s widely used because it’s naturally stable, affordable, and able to survive processing, shipping, and storage without degrading easily.
Vegan and non-GMO forms are available (and used in Herb-Science products)
We use a liquid form of B2 to make it easier to absorb, easier to take, and free from unnecessary fillers.
Liquid vitamins:
✅ Bypass some digestive breakdown, leading to faster absorption
✅ Are ideal for those with gut issues, low stomach acid, or trouble swallowing pills
✅ Allow you to easily adjust your dose if needed
✅ Don’t require binders, coatings, or other unnecessary additives
Plus, our formula is stabilized with plant-based glycerin and purified water—no alcohol, artificial colors, or preservatives.
We use vegetable glycerin in our Liquid B2 as a natural way to stabilize and sweeten the formula—without needing alcohol, artificial sweeteners, or chemical preservatives.
What is glycerin?
Glycerin is a clear, slightly sweet, plant-derived liquid. It’s made by extracting natural oils (from palm oil) and refining them into a pure, safe form.
Why do we use it?
✅ Natural preservation — helps protect the stability and potency of the B12 without harsh chemicals.
✅ Mild natural sweetness — improves the taste naturally, with no added sugars.
✅ Improved texture — makes the drops easy to take directly under the tongue or mix into water.
Important to know:
We use vegetable-sourced, non-GMO glycerin.
It contains no alcohol, no artificial flavors, and no added sugars.
Glycerin is generally recognized as safe (GRAS) by the FDA when used in supplements.
🔥 Quick summary for customers:
We use pure, plant-based glycerin to naturally preserve and sweeten our B12 drops—no alcohol, no artificial ingredients, and no added sugars.
