The short answer
Tanning gummies built on astaxanthin and lycopene at clinical doses have a strong human safety record and mild, mostly cosmetic side effects. Tanning gummies built on beta carotene carry a real risk of orange skin cast and, critically, a well-documented lung cancer risk in current or former smokers. ChUV uses zero beta carotene.
Are tanning gummies safe?
Yes, tanning gummies that use non-pro-vitamin-A carotenoids (like astaxanthin and lycopene) at label doses are safe for the general adult population. Both compounds have been studied in humans for years across cardiovascular, skin, and ophthalmology research without serious adverse events at supplement ranges. The safety picture changes sharply with beta carotene, which is covered in its own section below.
The correct framing: the safety question is not tanning gummies vs nothing. It is tanning gummies vs UV exposure. Compared with hitting a tanning bed or burning yourself in the sun to produce melanin, carotenoid-based pigmentation is the safer path by a wide margin, because it does not involve DNA damage from UV radiation.
Common side effects of tanning gummies
Across the tanning gummy category as a whole, the reported side effects cluster into four buckets:
- Carotenoderma (the orange cast): yellow-orange pigment buildup in high-keratin zones (palms, soles, nasolabial folds). Almost always caused by beta carotene or an oversupplied carotenoid blend. Reversible on discontinuation.
- Mild GI discomfort: nausea or loose stool if taken on an empty stomach. Carotenoids are fat-soluble and absorb better with a meal that includes some fat.
- Temporary stool discoloration: occasional reddish tint, benign and self-resolving.
- Slower onset than expected: not a medical side effect, but worth calling out. Carotenoid pigmentation is cumulative. If a gummy promises visible results in under two weeks, the math does not work.
The beta carotene risk
There is one well-documented safety signal in the tanning gummy category, and it has nothing to do with the broader carotenoid family. Two large randomized trials, the ATBC study (1994) and the CARET trial (1996), found that supplemental beta carotene measurably increased lung cancer incidence in current and former heavy smokers. The finding was so consistent across both trials that it permanently changed how beta carotene supplementation is recommended.
That is the single most important safety fact in this category. Tanning gummies that use beta carotene as their primary pigment are inherently higher risk for a specific subgroup of the population, and consumers have no way to know the difference without reading the supplement facts panel.

Who should avoid tanning gummies
Regardless of the specific formula, tanning gummies are not appropriate for:
- Pregnant or nursing women, where no safety profile has been established for concentrated carotenoid supplementation.
- Children under 18, for the same reason.
- Anyone with a known carotenoid sensitivity, though this is rare.
- Anyone taking medications with documented carotenoid interactions. When in doubt, ask your doctor.
Current or former smokers specifically should avoid beta-carotene-based tanning gummies. Astaxanthin and lycopene do not carry the same risk signal and are generally appropriate.
How ChUV is formulated for safety
ChUV tanning gummies contain 11 mg of astaxanthin (from Haematococcus pluvialis microalgae) and 5.5 mg of lycopene (from non-GMO tomato extract) per daily gummy. Each gummy contains:
- Zero beta carotene
- Zero pro-vitamin-A carotenoids
- Zero artificial dyes
- Zero biotin (often added to tanning gummies as a label flourish, not for skin outcome)
Every batch is third-party tested for heavy metals (against USP <232> limits), microbial safety, HPLC potency assay, and identity. The safety posture is deliberately conservative: we would rather lose the cosmetic punch of beta carotene than ship a product that carries a documented cancer-risk signal for smokers.
Tanning gummies side effects FAQ
Are tanning gummies safe?
Tanning gummies formulated from non-pro-vitamin-A carotenoids like astaxanthin and lycopene have a strong human safety record at supplement doses. The one well-documented safety exception is high-dose beta carotene supplementation in current or former smokers, which two major trials (ATBC 1994 and CARET 1996) linked to increased lung cancer incidence. ChUV contains zero beta carotene.
Do tanning gummies have side effects?
The most common side effects are cosmetic rather than medical: carotenoderma (a yellow-orange palm cast from beta carotene or under-dosed blends), mild GI discomfort if taken on an empty stomach, and rarely, temporary stool discoloration. Astaxanthin and lycopene at clinical doses are well tolerated in human trials.
Can tanning gummies cause orange skin?
Yes, if the formula uses beta carotene. Beta carotene disproportionately deposits in high-keratin zones (palms, soles, nasolabial folds) and produces a yellow-orange cast at supplement doses. Astaxanthin and lycopene produce a warmer, more balanced red-gold tone that reads as natural sun exposure.
Are tanning gummies bad for your liver?
No evidence that astaxanthin or lycopene at label doses burden the liver. Carotenoids are fat-soluble and cleared through biliary and sebaceous routes. If you have an existing liver condition or take medications with known interactions, consult your doctor before starting any supplement.
