WHILE her sisters are selling clothes and makeup, wellness guru Kourtney Kardashian has broken into the supplements biz.

Last week, she debuted her Lemme line of health gummies, which promise to energize, de-stress, and promote focus – but a dietitian tells The U.S. Sun why he's not completely sold on the products and shares the cheap alternative that's a better bet.

Kourtney, 43, launched Lemme on September 27, saying in a press release that she spent years "struggling to find the right supplements."

The line includes Lemme Matcha, which promises a boost in energy; Lemme Focus, which is supposed to help with concentration; and Lemme Chill, which the brand claims will de-stress you – all for $30 a bottle.

"I embarked on a journey to create science-backed products that you would legitimately look forward to taking every day," Kourtney said.

But speaking to The U.S. Sun, Andy De Santis, a Registered Dietitian based in Toronto, says that the "science" isn't fully convincing on all fronts.

The product page for Lemme matcha says it offers "cellular energy support" and will banish the "3pm slump."

Ingredients include 24 mcg Vitamin B12, 50mg Organic Matcha Green Tea, and 20mg Coenzyme Q10 (CoQ10) – but De Santis says the science simply doesn't show that these will wake most people up.

"There’s not really good evidence that just taking B12 in a supplement is going to add any pep to your step," he says.

"If someone is very low in B12, fatigue could be a side effect of that. Rectifying that could theoretically improve their energy levels.

"But if you take an otherwise healthy person who has normal blood levels of B12, there’s no evidence that says taking it is gonna greatly enhance your daily vigor."

There's a similar issue for CoQ10, which is "definitely a popular supplement" – but for athletes, not office workers sitting at their desks.

Studies show that "you may improve exercise performance" and it can "offer some little boost to endurance," but there's no proof you'll have "way more energy to go type on your computer."

Finally, the amount of matcha green tea powder in two gummies is just not enough for an energy boost.

"It has little to no caffeine – not enough to make a meaningful impact on fatigue and energy levels," he says.

If more energy is your goal, he adds, you'd be better off just drinking a cup of coffee.

"Stay laser-focused," reads the product description for the concentration gummies, adding that the "clinical dose of citicoline helps you focus better and think more clearly throughout the day."

Lemme advertises that these gummies – which have 25 mcg Vitamin D, 4.8mcg Vitamin B12, 250mg citicoline, 25mg Lion’s Mane Extract, and 10mg Coconut MCT Oil – help you "get through tasks faster" and "concentrate better and think more clearly."

De Santis says there may be something there with this supplement – but it's not based on "irrefutable high-quality evidence."

In scientific organizations, he said, "there have been claims rejected on better research than this."

First, there's Vitamin B12, which has the same issue here as it does with the matcha gummies – it'll only make a difference if you have a deficiency.

Vitamin D is great for immunity and bone health, but it isn't associated with concentration – and again, for an otherwise healthy person, De Santis says is "really iffy" and unlikely to make a difference.

He adds that there are also "no high-level studies that say MCT oil is really gonna enhance your focus."

Citicoline and lion's mane have been studied more, with some evidence showing that they can improve focus and memory in otherwise healthy people.

That being said, De Santis would still recommend just drinking a cup of joe.

"If you have the afternoon ahead of you and you want to feel focused, and you have a choice – pop one of these or drink a cup of coffee – the reality is, caffeine is probably more effective for that purpose, to improve focus and concentration," he says.

Finally, Lemme says the de-stressing gummies will "help keep you calm, cool, and connected to your higher self."

They're made with 20mcg Vitamin D, 300mg ashwagandha root, and a proprietary blend of lemon balm extract, passion flower extract, and goji berry extract.

According to De Santis, this one is the most likely to deliver on its promises, but only because of the ashwagandha.

"It has the potential to lower cortisol levels, which is the infamous stress hormone," he says.

"It also has the potential to reduce people’s perceived stress levels. There are multiple studies ... that if people take ashwagandha at this level, they report feeling less stressed," he continues.

But while the ashwagandha element is "pretty sound," the quality of research on the ingredients is much less – and not enough to make any confident claims.

To that end, he says that it might make more sense to buy just ashwagandha root.

While Kourtney's gummies are $30 for a pack of 60 – and the suggested serving is two at a time – a bottle of 120 capsules with a higher concentration of ashwagandha can be purchased on Amazon for $9.47.

Nature's Key also sells a bottle of 60 strawberry-flavored ashwagandha gummies for $12.14.

"[Lemme] is more expensive than it might be if you’re doing targeted supplementation for sure. It’s tough to say that this is justified," says De Santis.
