Warm, natural tone
Astaxanthin + lycopene deposit in the skin for a golden glow, not a carrot-orange cast.

CAYO Nutra, ChUV
ChUV is a daily tanning gummy that builds a warm, natural tone from the inside, with no UV and no beta carotene. One strawberry gummy carries 220 mg of microalgae providing 11 mg of pure astaxanthin, and 55 mg of lycopene extract providing 5.5 mg of pure lycopene. Most people notice a warmer tone by week 3 or 4, with full results around week 8. If you have been comparing tanning pills, tanning supplements and self tanning gummies, this is the gummy, and the color it builds is your own.

Why ChUV
Astaxanthin + lycopene deposit in the skin for a golden glow, not a carrot-orange cast.
Antioxidant support against UV-induced oxidative stress from the inside out.
Vegan, non-GMO, gluten-free, made in a GMP-certified USA facility.
What's inside
Every gummy is formulated to hit the clinical ranges that the studies on carotenoid pigmentation and photoprotection actually used, not a dusted sprinkle for the label.
Chew a single gummy with a meal that includes some healthy fat for best absorption.
Carotenoid accumulation is gradual. Expect noticeable warmth by week 3-4 and full results at week 8.
The color fades as your body clears the pigment. Daily use keeps the tone locked in.

Skin Science
Carotenoids are pigments. Taken daily, they settle into the outer layer of your skin and read as warmth on their own, with zero UV. Get sun on top of that and the color goes further, because the same molecules are working on the oxidative stress that usually turns exposure into burn. Step through the three below to see where each bit of tone comes from.
Where the tone comes from
Swatches are illustrative. The real shift is subtle, and where you land depends on your own starting tone.
Whatever your skin does on its own. Nothing is deposited in the outer layers, so there is no extra pigment sitting there to catch the light. This is the baseline the other two are measured from, and it is different for everybody.
Astaxanthin and lycopene circulate, then deposit in the stratum corneum and upper epidermis, the outermost layers light passes through first. That deposit is what your eye reads as a warm, sun-kissed tone. It builds over 4 to 8 weeks and it does not need a single minute of UV.
UV still does what UV does. Melanocytes at the base of your epidermis produce melanin and push it upward, and that is your actual tan. What changes is the layer sitting above them: astaxanthin is one of the most studied carotenoid antioxidants, and it is quenching the free radicals UV generates on the way in. The tan settles on top of the warmth you already built, so the tone reads deeper and richer instead of flat.
ChUV is not a sunscreen and does not block UV. Keep wearing SPF. Results vary with starting skin tone, diet, and how consistently you take it.
The Timeline
Scrub through eight weeks on ChUV. Pigment saturation, biology, and the moment the shift becomes visible, week by week.
Serum carotenoid levels rising. Antioxidant activity active.
Astaxanthin and lycopene enter systemic circulation and begin to deposit in dermal tissue. You will not see the shift yet. The biology is running underneath.

The Category
Three different products get shelved under “tanning” and they work nothing alike. Whether you have been searching for tan gummies, tanning pills or an oral tanning supplement, it is worth knowing which one you are actually buying.
Sits on top. Leaves with those cells.
Time to visibleTomorrow
Topical, and the fastest of the three. DHA reacts with dead cells on the very surface of your skin, so the color is real, but it is sitting on top. It goes patchy where you sweat or shave, and it washes out with those cells inside about a week. It changes nothing about what your skin does under UV.
Goes all the way through. Wrong color.
Time to visible3 to 6 weeks
The oral category ChUV belongs to, and most of them are built on beta carotene. At a dose high enough to shift your skin tone, beta carotene is the ingredient that produces the unnatural yellowish-orange cast people are trying to avoid in the first place. ChUV contains none of it.
Builds through the outer layers.
Time to visible4 to 8 weeks
A carotenoid supplement you chew. Astaxanthin and lycopene are pigments in their own right, and taken daily they deposit in the outer layers of your skin and read as warmth with no UV at all. That is carotenoid tanning, and it builds over 4 to 8 weeks instead of appearing overnight.
Whichever format you land on, the question worth asking is the same. Not gummies for tanning versus a natural tanning supplement in capsule form, but which carotenoid is doing the work, and how many milligrams of it you actually get per day.

Questions, answered
Astaxanthin offers real internal photoprotection by neutralizing UV-induced free radicals at the cellular level. For prolonged outdoor exposure, pair ChUV with topical SPF. Think of them as complementary.
Generally yes. Astaxanthin and lycopene are fat-soluble, so take ChUV with a meal that contains some healthy fat for best absorption.
ChUV is vegan, non-GMO, gluten-free, and free of the major allergens. See the full supplement facts panel on the product page.
Subscriptions ship free. One-time orders ship at standard domestic rates. Orders leave our fulfillment facility within 1 to 2 business days.
Most people see a first noticeable warmth in weeks 3-4 and full tone expression by week 6-8. Carotenoid pigmentation is cumulative, so consistent daily use matters more than dose stacking.
Yes. Carotenoid accumulation is gradual, and so is the fade. Daily use keeps your tone consistent.
You chew a carotenoid, it enters circulation, and it deposits in the stratum corneum and upper epidermis, the outer layers light passes through first. That deposit is the color. Reaching a steady state takes 4 to 8 weeks of daily dosing.
The full pathway, how tanning gummies workSame category, different formula. Most tanning pills are built on beta carotene, which at a tanning dose produces an unnatural yellowish-orange cast. ChUV uses astaxanthin and lycopene instead, and contains no beta carotene.
Why we skip beta caroteneThe effect people report most with any carotenoid is a change in skin tone, which is the reason for taking it. ChUV is one gummy a day at the doses printed on the panel. We keep a full write-up rather than a one-line answer, and as with any supplement, talk to your doctor about your own situation.
Tanning gummies side effects, in detailThe format matters less than what is inside it. Most tanning pills lean on beta carotene, which at a tanning dose produces an unnatural yellowish-orange cast. Check the actual milligrams of each carotenoid on the label before you decide between a pill, a capsule or a gummy.
Why we skip beta caroteneWe wrote the comparison rather than just naming ourselves. The two things worth checking on any label are the actual milligrams of each carotenoid, and whether the formula leans on beta carotene to do the work.
