4 Clinically-Backed Ingredients in Wonder Happy That Support a Better, More Positive Mood
Herbs, spices, and adaptogens have been used by Ayurvedic medicine practitioners to improve mood and brain chemistry for thousands of years. Here are the recent clinical studies that prove the efficacy of these plants.
01Ingredient
Saffron Improved Mood vs. Placebo Across 23 Clinical Trials
Saffron is a spice hand picked from the inside of a purple crocus flower. Used for more than 3,000 years, Persian doctors gave it to people suffering from a “heavy heart.”
In 2019, researchers compared 23 studies to evaluate its impact in a clincial setting1, and found that Saffron lifted mood measurably more than placebo. In the biggest study so far, 202 adults with low mood took saffron or a placebo for 12 weeks. 72%2 of the saffron group felt a real lift, While only 54%2 of the placebo group did.
Wonder Happy: 30mg of 10:1 saffron extract. That equals 300mg of raw saffron.
02Ingredient
73% of People Taking 5-HTP Felt Better Within 8 Weeks
Your body uses tryptophan to create serotonin, the "happiness neurotransmitter". Dietary tryptophan comes from foods like turkey and oats. But about 95% of that tryptophan gets used up in other chemical processes and never reaches the brain. 5-HTP is the last step in the process used to create serotonin, so when supplemented by eating the seed of an African plant, it circumvents other chemical processes and gets directly converted into serotonin4.
In one 8-week study, 60 adults with low mood took 5-HTP. Mood scores got better by week two. By the end, 73%5 of people saw improvements.
Wonder Happy: 100mg of 5-HTP.
Do you take an SSRI, SNRI, MAOI, or any other medicine that affects serotonin? Ask your doctor before you start Wonder Happy.

4 in 10 U.S. Adults Are Low on the Nutrient Serotonin Runs On
Your skin makes vitamin D from sunlight, and your brain uses it as the chemical "switch" to turn on serotonin production6. In the winter, most people struggle getting enough sun to keep this process running smoothly.
Researchers ran blood tests on 4,495 U.S. adults and found 41.6%7 were low on vitamin D. Another team looked at 14 studies with 31,424 people8. People with low mood had less vitamin D. And people with the lowest levels were about twice as likely to suffer from mood problems.8
Wonder Happy: 2,000 IU of vegan D3 from lichen. That’s more than the daily 600 to 800 IU and under the 4,000 IU9 safe limit.
04Ingredient
The “Happiness Tree,” Has Been Prescribed for mood support for 2,000 Years
Albizia is the silk tree. In Traditional Chinese medicine, its pink puffy flowers are called He Huan, “the happiness tree.” In China’s oldest herb book, the flower was noted for its ability to calms the spirit and makes people cheerful. Herbalists use both parts of the tree. The bark is not a sedative, so you feel calm, not sleepy. Most people feel it first, while saffron and 5-HTP build up over 2 to 4 weeks.
In a 2007 study,10 mice given albizia extract showed a clear lift in a mood test. In another 2004 study, rats that ate albizia bark extract for 7 days acted calmer in a stress test, without showing signs of sedation11
Wonder Happy: 200mg of 10:1 albizia flower extract plus 200mg of 10:1 bark extract. That equals 4,000mg of raw herb. Almost no other mood gummy has it.

Frequently Asked Questions
If there's no melatonin, what actually helps me sleep?
Wonder Sleep blends six clinically studied mushrooms and botanicals (Reishi, Saffron, GABA, Corydalis, Chamomile and Passionflower) that help calm the mind and body and support your natural sleep cycle, without adding hormones.
Will I feel groggy the next morning?
No. Wonder Sleep is formulated to help you wake up refreshed, not foggy. It works with your body's natural rhythm, so you get the most out of your sleep while you're asleep and feel clear-headed when you wake up.
When should I take Wonder Sleep?
Take two gummies about 30 minutes to an hour before bed. For best results, take them nightly. The ingredients build on each other and work even better over time.
What's wrong with melatonin?
Melatonin is a hormone your body makes on its own to start sleep. When you keep supplementing it, you're telling your body it doesn't need to make as much itself. Research also shows only modest benefits for falling asleep, and it's commonly linked to next-day grogginess.
How is it sweet if it's zero sugar?
Wonder Sleep is sweetened with maltitol and isomalt, sugar alternatives that are lower in calories and won't spike your blood sugar. Each serving is just 15 calories, and the gummies are 100% vegan with a wild elderberry flavor.
Can I combine it with other Plant People gummies?
Absolutely. Listen to your body first: when adding a new supplement, introduce one at a time and give yourself a few days to adjust.
