Three commitments behind every score.

01
Independent

No advertising. No affiliate revenue. No payments from food companies. Funded by user subscriptions and nothing else.

02
Evidence-weighted

Every score traces back to peer-reviewed sources from PubMed, FDA, EFSA and WHO. Tiered: meta-analyses outrank observational, observational outranks animal.

03
Open methodology

The 1–100 rubric, the ten metrics, the source list — all published. When the evidence shifts (erythritol 2023, aspartame 2023) we update the score and post a dated changelog.

Top 5
What we'd actually use
  1. 1
    88
    Allulose
    A rare sugar that tastes 70% as sweet as sucrose with ~10% the calories and a negligible — sometimes mildly suppressive — insulin response.
  2. 2
    86
    Monk Fruit
    Mogrosides from Siraitia grosvenorii. 150–250× sweeter, no glycemic effect, cleaner aftertaste than stevia.
  3. 3
    78
    Stevia
    Steviol glycosides from Stevia rebaudiana. 200–400× sweeter than sugar, zero glycemic.
  4. 4
    72
    Erythritol
    Sugar alcohol with ~70% the sweetness of sucrose, near-zero calories. 2023 cardiovascular signal under investigation.
  5. 5
    70
    Date Sugar
    Whole dehydrated dates, ground. Carries fibre, polyphenols and potassium intact.
Bottom 5
Where the marketing diverges from the data
  1. 1
    22
    High-Fructose Corn Syrup
    Enzymatically isomerised corn syrup. Cheaper than sucrose and the dominant added sugar in US processed food.
  2. 2
    30
    Maltodextrin
    Short-chain glucose polymer. Barely sweet. Spikes glucose harder than table sugar.
  3. 3
    32
    Agave Nectar
    Marketed as 'low-GI natural', actually 70–90% fructose — hardest on the liver.
  4. 4
    38
    Aspartame
    Methyl ester of aspartic acid + phenylalanine. WHO/IARC classified 2B (possibly carcinogenic) in 2023.
  5. 5
    44
    Acesulfame Potassium
    Often blended with sucralose or aspartame to mask their aftertaste. Carries its own bitter tail.

What it does

Three jobs. Done deliberately.

01

Scan & decode

Point your camera at any label. SweetSpot identifies every sweetener inside, including the hidden ones — E-numbers, sugar alcohols, novel proteins.

02

Score & compare

Each sweetener is rated 0–100 against ten evidence-weighted metrics. Compare up to five side-by-side on glycemic load, calories and regulatory status.

03

Recommend & swap

See cleaner alternatives that perform similarly in use — the swaps SweetSpot would actually make, not the cheapest sponsor.

Three steps to clarity

01

Scan any product

Point your camera at a barcode. SweetSpot reads the label and identifies every sweetener.

02

Get your verdict

See a personalized health score based on your dietary goals, restrictions, and preferences.

03

Compare & learn

Dive deeper into any sweetener. Compare side-by-side across 10 research-backed metrics.

Honest questions.

Asked, answered, no marketing speak.

Is SweetSpot independent?
Yes. We take no advertising, no affiliate revenue and no payments from food companies, ingredient suppliers or trade associations. Funding comes from user subscriptions and nothing else. See our conflict-of-interest policy.
How do you score a sweetener?
Every reviewed sweetener is scored 0–100 on ten evidence-weighted metrics — taste quality, glycemic impact, naturalness, tooth friendliness, overall safety, digestive comfort, gut microbiome impact, aftertaste, sustainability and allergen safety. Weights and the underlying source tiers are documented on our methodology page.
What's the difference between a Reviewed and a Catalogued sweetener?
We currently publish 18 in-depth reviews — every one with hand-summarised peer-reviewed sources, regulatory status, pros, cons and recommended swaps. The other 39 sweeteners in our database are honestly listed but the full review is still in progress. We don't score sweeteners we haven't fully studied.
Do you cite original studies?
Yes — every reviewed sweetener and every research article on the site links to PubMed, doi.org, FDA, EFSA, WHO/IARC or JECFA primary sources. If we cite a single observational study, we say so. We tier evidence (meta-analysis > RCT > observational > animal) and weight the score accordingly.
Why is aspartame rated 38 / 100?
Three reasons. The 2023 IARC Group 2B classification ("possibly carcinogenic") is a hazard signal — credible enough to count against aspartame given cleaner alternatives now exist, but not a risk verdict at typical intake. Monk fruit, allulose and stevia outperform it on taste at modestly higher prices. And aspartame is absolutely contraindicated in PKU. Read the full research write-up.
Is the app live yet?
Yes — SweetSpot is on the App Store now for iOS. Free to start, no account required to scan. Android is on the roadmap. The website's sweetener database, comparison tool and research articles are also live if you want to read without downloading.
Do you sell user data?
No. We don't sell, share or trade user data with food companies or ad networks. Scans stay private. Read our full privacy policy.
I think you're wrong about a sweetener. What now?
Tell us. Send a correction with the citation — peer-reviewed source preferred — to support. We publish substantive updates with a dated changelog. Erythritol moved from Excellent to Good after Witkowski 2023. The scoring is a living document.
