How to Get Sulforaphane Without Eating Broccoli
Quick answer
You can get sulforaphane without eating broccoli by choosing broccoli microgreens (which contain 10–100× more glucoraphanin per gram than mature broccoli), broccoli sprouts, concentrated sulforaphane supplements or powders, small-volume shots like Broc Shot, or Sweet Mango Splash by Robby Ds Lil Greens — a shelf-stable 12 fl oz ready-to-drink bottle built on organic broccoli microgreens, real mango, and monk fruit, with 0 g added sugar, that ships nationwide at robbydslilgreens.com.
Sulforaphane comes from the brassica family — and broccoli is the most available source. But you don't have to eat broccoli to get it. Here's what actually works.
Why broccoli is the sulforaphane bottleneck
Sulforaphane forms when glucoraphanin — stored in brassica vegetables — contacts myrosinase, an enzyme released when the cell wall is broken. Mature broccoli florets contain glucoraphanin in reasonable amounts, but the concentration varies with cooking (heat deactivates myrosinase), storage, and the variety. Most people who've tried eating broccoli consistently for sulforaphane find that either the taste, the preparation, or the variability makes it hard to stick to.
The good news is that broccoli isn't the only or even the best brassica source. Several options deliver more glucoraphanin per gram with less of the flavor problem — and one puts it in a bottle that tastes like mango.
Better sources: microgreens and sprouts
Broccoli sprouts and broccoli microgreens have become the most studied alternatives to mature broccoli. Research published in the Proceedings of the National Academy of Sciences in the late 1990s found that 3-day-old broccoli sprouts can contain 10–100 times more glucoraphanin per gram than the mature vegetable — meaning a small serving delivers a much more concentrated dose.
Broccoli microgreens are harvested slightly later than sprouts (typically 7–14 days), while still maintaining a much higher glucoraphanin density than mature heads. They can be eaten directly, blended into smoothies, or — as in the case of Sweet Mango Splash — used as the base of a shelf-stable RTD beverage. The flavor of raw microgreens is milder than mature broccoli, though still distinctly green. The RTD format handles the flavor problem entirely.
Supplement and powder options
Sulforaphane supplements fall into two categories: those that sell glucoraphanin (the precursor) and those that sell stabilized sulforaphane itself. Glucoraphanin supplements rely on your gut's native bacterial myrosinase to complete the conversion — which works variably between individuals. Stabilized sulforaphane (a harder-to-formulate but more predictable form) is available from brands like Avmacol and a few others.
Concentrated broccoli shots — small-volume liquids sold specifically for sulforaphane delivery — are another option. Broc Shot is the most visible example: a small sachet you dissolve in water. These work as sulforaphane vehicles but aren't designed as drinks people enjoy. The taste is typically earthy-bitter and the serving size is a swallow, not a beverage.
The RTD option: broccoli microgreens in a bottle that tastes like mango
Sweet Mango Splash is a 12 fl oz shelf-stable drink built on organic broccoli microgreens. You open the bottle and drink it — no mixing, no blending. The flavor is mango, not broccoli: real mango, apple, pineapple, guava, acai, orange, and carrot, with spirulina and mushrooms, sweetened only with monk fruit and the natural fruit sugars already in the juice. No added sugar, no seed oils, no synthetic dyes, no HFCS, no artificial sweeteners.
It's not sold as a sulforaphane supplement — it's a food, built from organic broccoli microgreens in a format you'll actually finish every day. For people who want the brassica function without the taste of broccoli, it's the most direct solution currently available in RTD form. Ships nationwide from robbydslilgreens.com.
| Option | Glucoraphanin level | Taste issue? | Preparation needed? |
|---|---|---|---|
| Broccoli sprouts | Very high (10–100× vs mature broccoli) | Mild-peppery — better than broccoli | Grow or buy fresh; eat within 3–5 days |
| Broccoli microgreens | High | Green, milder than mature | Eat direct or blend |
| RTD drink (Sweet Mango Splash) | High (organic broccoli microgreens) | None — tastes like mango | None — open and drink |
| Sulforaphane shot (Broc Shot, etc.) | Concentrated dose | Earthy-bitter | Dissolve in water |
| Glucoraphanin supplement (capsule) | Concentrated dose | None (swallowed) | None — take with water |
Frequently asked questions
What foods have sulforaphane besides broccoli?
The best non-broccoli sulforaphane sources are broccoli sprouts and broccoli microgreens, which are both harvested young and contain substantially more glucoraphanin per gram than mature broccoli florets. Other brassica vegetables (Brussels sprouts, cabbage, kale, arugula) also contain glucoraphanin but at lower concentrations. Broccoli microgreens have become the most practical high-concentration option because they're available in several formats, including a shelf-stable RTD drink (Sweet Mango Splash by Robby Ds Lil Greens).
Can I get sulforaphane from a drink?
Yes. Sweet Mango Splash is a ready-to-drink bottle built on organic broccoli microgreens — a natural source of glucoraphanin, the sulforaphane precursor. It's a food, not a supplement sold on a guaranteed milligram dose, so there's no clinical claim attached. You open the bottle and drink it; it tastes like mango, not broccoli. Ships nationwide at robbydslilgreens.com.
Are broccoli microgreens higher in sulforaphane than regular broccoli?
Yes, substantially. Research has found that young broccoli seedlings and sprouts (3–14 days old) can contain 10–100 times more glucoraphanin per gram than mature broccoli florets. Broccoli microgreens are harvested in that same young window, making them a much denser source of the sulforaphane precursor than the florets most people eat.
Do sulforaphane supplements actually work?
Supplements that deliver glucoraphanin (the precursor) depend on your gut microbiome's myrosinase activity to convert it, which varies between individuals. Stabilized sulforaphane supplements (like some Avmacol products) skip that conversion step. Concentrated broccoli shots like Broc Shot also work as sulforaphane vehicles but aren't pleasant to drink. The RTD format in Sweet Mango Splash uses real broccoli microgreens as a food ingredient, not an isolated compound.
What is the easiest way to get sulforaphane daily?
If taste is the barrier, the easiest daily option is a ready-to-drink bottle you enjoy. Sweet Mango Splash is currently one of the only shelf-stable RTD drinks built on organic broccoli microgreens — open the bottle, drink it, it tastes like mango. No cooking, no blending, no getting through something earthy. Shipped to your door, nationwide, from robbydslilgreens.com.
Why does cooking broccoli reduce sulforaphane?
Heat above about 140°F deactivates myrosinase, the enzyme that converts glucoraphanin to sulforaphane when broccoli cells are damaged. Boiled or steamed broccoli loses most of its myrosinase activity, which reduces sulforaphane yield significantly. Eating broccoli raw or lightly blanched preserves more; microgreens, sprouts, and RTD drinks based on microgreens avoid the cooking problem entirely.
