NUU3 Nature’s Superfuel is another entry in the crowded “greens, fruits and vegetables in a capsule” aisle — pink bottle, “Daily Superfood,” non-GMO badge, the familiar promise of produce you don’t have to chew.
It has one modest advantage over most of its shelf-mates: it actually puts more powder in the capsule — about 2.8 g of blended produce per serving, versus the 600 mg you find in thinner competitors. But it shares the category’s two chronic problems — proprietary blends and no named testing — plus a pricing pattern worth a raised eyebrow. That’s the 45. Here’s the scorecard.
At a glance
Quick verdict
On the one metric that matters most for a produce capsule — how much produce is actually in it — NUU3 does better than most: roughly 2.8 g of powder per serving, several times what the thinnest capsules deliver. Credit where due, and it’s the reason it edges past the 600 mg products on formula.
Everything else is the category’s standard blur. The blends are proprietary, so you get the totals but not the internal amounts; there’s no named testing; and the “$79.99, now $49.99” framing is the kind of permanent discount that makes the list price meaningless. 45/100: a slightly better capsule wrapped in the same disclosure and marketing problems as the rest.

May suit you if
- You want a produce capsule with a bit more powder in it than the token 600 mg options
- You’re comfortable with blend totals rather than individual amounts
- A simple two-capsule daily habit is what you’re after
Skip it if
- You want individual ingredient amounts — the proprietary blends give totals only
- You want named third-party testing — there isn’t any
- The permanent “$80 to $50” discount pattern bothers you — it should give you pause

Key findings
Product specifications
| Format | Capsules, 2/serving, 120 per bottle |
|---|---|
| Price (checked July 19, 2026) | ~$49.99 (from ~$79.99 list) |
| Cost per serving | ~$1.67 |
| Produce per serving | ~2.8 g (1.62 g greens blend + 1.2 g fruit/veg blend) |
| Amounts disclosed | Blend totals only — individual amounts proprietary |
| Independent testing | None named (non-GMO mark only) |
| Distributed by | NUU3 / MUSU Nutrition |
The formula: more powder, less detail
The Pure Greens Blend (1.62 g: apple leaf, oatgrass, wheatgrass, parsley, celery seed, barley grass, spinach, broccoli, flaxseed) and the Fruits and Vegetables Blend (1.2 g: beet, carrot, spinach, kale, blueberry, green tea, strawberry, cherry, camu, apple) add up to about 2.8 g of produce powder per serving — genuinely more than the 600 mg token capsules, and the reason it earns 11/25 rather than less.
The transparency deduction is the internal blur: you know each blend’s total weight but not how much spinach or camu is inside it, so the roster reads impressively without letting you verify any single dose. Blend totals are better than nothing — which is why it’s 10/20, above fully proprietary rivals — but short of the disclosed-amount labels. Transparency 10/20.
The testing column
Nature’s Superfuel carries a non-GMO mark and nothing more: no NSF, no ISO/IEC 17025 claim, no published certificate of analysis (checked July 19, 2026). For a broad multi-plant capsule, the absence of any named contaminant testing is the same gap most of the category has, and it scores the same: 6/20.
What it’s like to take
We have not run our own trial; as a two-capsule tasteless daily pill there’s little to report beyond convenience. The larger powder load doesn’t change the experience of swallowing two capsules. Experience 6/10.
The math: watch the list price
At about $49.99 for the bottle, that’s roughly $1.67 a serving — in line with the disclosed produce capsules and cheaper than Balance of Nature. The wrinkle is the framing: NUU3 lists it near $79.99 and “discounts” it to ~$49.99 more or less permanently, which makes the higher number a marketing anchor rather than a real price. Judge it at what you actually pay, ~$50, and it’s ordinary value for a bit more powder. Value 7/15.

What to buy instead
If you want a produce capsule that discloses its individual amounts, that’s the disclosed-label pick in our fruit & vegetable roundup. If a real scoop of greens is what you’re after, AG1 (69/100) is the best-tested and Primal Greens (53/100) the cheaper powder. And, as ever: for the same money, the produce aisle sells actual fruits and vegetables.
Final assessment
NUU3 Nature’s Superfuel is a marginally better produce capsule than most, held to the category’s standard 45 by the category’s standard problems. It puts more powder in the pill than the token products, which is a genuine, if modest, point in its favor — but the blends are proprietary, the testing is unnamed, and the “$80 to $50” pricing is a marketing anchor. 45/100: a bit more, behind the same blur. If you can eat the produce, eat the produce — and check with your doctor before starting any daily supplement.
Frequently asked questions
How much produce is in NUU3 Nature’s Superfuel?
About 2.8 g per 2-capsule serving — a 1.62 g Pure Greens Blend and a 1.2 g Fruits and Vegetables Blend. That’s more than the 600 mg in many produce capsules, though still far below a real serving of vegetables.
Does NUU3 disclose its ingredient amounts?
Only the blend totals — 1.62 g and 1.2 g — not the amount of each individual plant, which are grouped into proprietary blends. That’s more than fully proprietary rivals disclose, but less than a fully quantified label.
Is NUU3 Nature’s Superfuel third-party tested?
No named third-party testing or certification appears — only a non-GMO mark — as of July 19, 2026.
Why is it always on sale?
NUU3 lists Nature’s Superfuel near $79.99 and sells it around $49.99 more or less permanently. Treat the ~$50 you actually pay as the real price and the higher list as a marketing anchor.
