In a world inundated with supplement advertisements promising miraculous health benefits, it can be challenging to discern which ones are worth your money and which are not. While some supplements might seem like an easy shortcut to better health, experts caution that many of these products are not as effective as they claim to be.

From multivitamins to collagen supplements, we’ve compiled a list of commonly purchased supplements that you might want to think twice about before adding to your cart. With expert insight from medical professionals and nutritionists, we’ll help you navigate the supplement aisle with a more critical eye, ensuring you don’t waste your hard-earned money on products that might not deliver the results you’re hoping for.

1. Multivitamins

First thing's first: Dr. Austin Lake, recently shared insightful warnings about this very issue on TikTok, cautions against seemingly ubiquitous multivitamins, such as Centrum, Nature Made, One A Day, and Kirkland. Although these may appear to be a great way to get essential nutrients in one simple package, he bluntly states that "they just aren't going to be all that helpful to you" and "can potentially be a big waste of money" due to their low bioavailability and artificial additives. Dr. Lake encourages a shift toward obtaining essential nutrients from a well-rounded diet rather than relying on these widely marketed multivitamins.

2. Probiotics

Turning to probiotics, Dr. Lake stresses that "Probiotics are often a big waste of money because people are buying insufficient amounts of the right kinds of probiotics." He recommends ensuring you're taking the right quantities (typically ranging from 10 billion to 100 billion CFUs, depending on your health concerns), and underscores the importance of live activated cultures found in foods like kefir, sauerkraut, kimchi, and kombucha.

3. Biotin

Biotin is often marketed as a great option for a range of health needs, especially when it comes to beauty. However, this is the second supplement that Dr. Lake warns against. According to him, excessive intake could be detrimental to your health. "Biotin can actually deplete other B vitamins in your system, specifically B5," he says. Stressing the importance of B5 in hormone synthesis and energy production, he advises opting for a B complex instead, emphasizing the need for a balanced approach to supplementation.

4. Vitamin C

You may frequently hear about the importance of Vitamin C, especially when it comes to immunity. While getting enough Vitamin C in your diet is definitely important for your overall health, dietitian Krutika Nanavati says it may not be necessary or even beneficial at all to take a Vitamin C supplement. "You don’t require mega doses of it," she tells us. "Nor does it really prevent you from common cold as per findings." In fact, she notes that "there are no proven consistent effects people can get by taking Vitamin C routinely."

One major reason you may not benefit from taking a Vitamin C supplement is that it’s water soluble. "Being water soluble, excess Vitamin C gets secreted through urine," Nanavati explains. That means that if you get more than your body needs, your body will just end up flushing it out, anyway–i.e. it’s not going to supercharge your immune system. "There is no need to add it as an extra supplement," she confirms. Good to know!

5. Detox Supplements

Detox supplements (such as "Flat Tummy Teas" or allegedly miracle-working pills) often marketed with promises of cleansing the body and enhancing overall well-being, have faced increasing scrutiny for their questionable efficacy.  The fundamental premise behind detox supplements is the notion that they can rid the body of impurities and toxins, providing a fresh start for the internal systems. However, as Dr. Praveen Guntipalli, Medical Director and Owner of Sanjiva Medical notes, this idea runs counter to the natural processes already in place within the human body.

"Detox or cleansing supplements have been heavily condemned for making dubious claims and without scientific proof to support their efficacy," he warns. "These pills frequently claim to cleanse the body of impurities, increase energy levels, and improve general health." However, "These supplements' claims are often hazy and lack substantial evidence." Luckily, your body usually has the whole detoxification thing covered. As Dr. Guntipalli explains, "The human body already has organs that naturally detoxify the system, such as the liver and kidneys." These vital organs play a crucial role in filtering and eliminating toxins from the bloodstream.

6. Collagen for Hair Growth

If you're looking for a supplement to help reverse and treat thinning hair, Ghanima Abdullah, hair expert and cosmetologist at The Right Hairstyles, recommends skipping collagen. She notes that collagen supplements "come from the leftover gelatin" in the meat industry. "You'll see marine collagen in supplements too, but does it help thinning hair?

Collagen can help your hair come in stronger, and it will help the hair follicles hold on to existing hair for longer," Abdullah says. She stresses that "it won't help you grow new hair, however." Got it!
