Two things put these numbers in context. First, IM8 has a paid Trustpilot profile and actively invites customers to leave reviews. That is allowed, but invited reviews tend to skew positive. Second, 8% one-star reviews on more than 2,100 total means roughly 170 unhappy customers. That is not a red flag for a subscription brand of this size, but it is enough to show clear patterns, which we break down below.

What Customers Praise Most
Across the positive reviews, the same five themes come up again and again:
- Replacing a pill stack. Many reviewers say one daily drink replaced several bottles of vitamins, probiotics and joint supplements.
- Energy and focus. Long-term users often mention steadier energy and less afternoon fatigue. These are personal reports, not proof of effect.
- Digestion. A common comment is less bloating after the first few weeks.
- Taste. Many reviewers compare it to fruit juice rather than a grassy greens powder.
- Customer service. Support agents are often praised by name for fast refunds, order changes and subscription pauses.
A typical positive review comes from someone who has used the product for six months or more and found the subscription easy to manage. One October 2026 reviewer, for example, forgot to pause a renewal while overseas. Support cancelled and refunded the order the same day.
If that sounds like the experience you want, here’s where to order IM8; enter code GET for 10% off.
The Most Common IM8 Complaints
These are the recurring themes in IM8’s 1- to 3-star reviews, ordered roughly by how often they appear.
Subscription and billing issues
This is the largest category. Customers mention auto-renewals they forgot about, shipments arriving before they were ready, and unexpected charges. Most of these complaints end with a refund after the customer contacts support. Still, the frustration of being charged in the first place is real.
How serious is it? Moderate. It’s the standard risk of any auto-renewing subscription, not evidence of hidden fees. IM8 sends renewal reminder emails, and several reviewers say shipments are easy to delay by a week or two.
Shipping delays
Some reviewers report slow or missing deliveries, especially for international orders. Trustpilot’s own AI summary describes delivery experiences as mixed: many people praise fast shipping, while others report frustrating delays.
How serious is it? Low to moderate. It’s an inconvenience rather than a product problem, and most cases appear to be resolved by support.
Digestive side effects
This is the most important complaint category. Some reviewers report bloating, stomach upset or urgent bathroom trips, particularly in the first week. A smaller number mention heart palpitations or dizziness. One reviewer reported very high vitamin B12 levels on a blood test and stopped taking it. Another, in October 2026, reported increased appetite and weight gain; IM8 says it processed a refund.
How serious is it? It depends on the person. Early digestive changes are common with products that combine 10 billion CFU of probiotics, prebiotic fiber and digestive enzymes. IM8 also contains 200 mcg of B12, so people who take it alongside another multivitamin or B-complex can end up with very high intakes. Anyone with palpitations, dizziness or symptoms that don’t settle should stop and speak to a doctor.
Mixability and taste
A minority of reviewers say the powder doesn’t dissolve completely and leaves sediment, or that they simply don’t like the flavor.
How serious is it? Low. A shaker bottle and cold water solve most mixing issues. IM8 also offers three flavors and a variety pack.
Price
Even happy customers frequently knock off a star for cost. One October 2026 reviewer called it a good quality supplement but deducted a star purely because of the expense. Essentials Pro starts at $89 per month on subscription, and buying both products as the Beckham Stack costs more.
How serious is it? It depends on your current routine. If IM8 replaces several supplements you already buy, the math can work in your favor. If you only take a basic multivitamin today, it’s a big jump.
“I didn’t notice a difference”
Some three-star reviews simply say the reviewer felt nothing after several weeks.
How serious is it? This is honest and expected. A foundational supplement mostly helps if you have nutrient gaps. People who already eat well and have good lab results may notice little.
Most of these complaints can be avoided with the right setup, which we cover below. If you’re ready to try it carefully, order IM8 here and apply code GET.
What Experts Criticize
Customer reviews focus on experience. Expert reviews focus on the formula and the evidence behind it, and they are noticeably more critical:
- Proprietary blends. Illuminate Health praises IM8’s bioactive vitamin forms and NSF certification. However, it doesn’t recommend Essentials Pro, because several blends hide individual doses. It still ranks IM8 above Huel, Ka’Chava and Welleco.
- Underdosed extras. Innerbody and others note that the adaptogen and mushroom complex totals only 200 mg, below studied doses for ingredients like rhodiola and ginseng.
- Celebrity marketing and evidence. Registered dietitian Abby Langer argues that celebrity backing says nothing about efficacy. She also notes that IM8’s own trial results are largely self-reported and unpublished.
- Cost. ConsumerLab points out that stacking both products costs over $2,000 a year.
What experts generally don’t dispute is product quality. Essentials Pro is NSF Certified for Sport, which means it is screened for 280+ banned substances and checked for label accuracy. The debate is about value and evidence, not about whether the product is genuine.
If the vitamins, probiotics, MSM and CoQ10 are what you’re after, those are the parts experts rate best. You can check the current formula on IM8’s site and save 10% with code GET.
Is IM8 Legit or a Scam?
IM8 is a legitimate company. It is owned by Prenetics, which is listed on Nasdaq under the ticker PRE, with David Beckham as co-founding partner. Its products carry NSF Certified for Sport certification, and its customer support answers every negative Trustpilot review. Complaints center on subscriptions, shipping and individual tolerance, not on non-delivery or counterfeit products.
The fair criticism is that IM8’s marketing is louder than its evidence. Claims like “replaces 16 supplements” are about convenience. The clinical trial results it promotes are self-reported, and they had not appeared in a peer-reviewed journal at the time of writing.
Buying directly from IM8 is the safest route. Order through the official IM8 site and use code GET for 10% off.
How to Avoid the Most Common IM8 Problems
Most negative reviews describe avoidable situations. Here is how to prevent each one:
- Start with a single box if you’re unsure. A one-time purchase avoids auto-renewal surprises while you test tolerance and taste.
- If you subscribe, set a reminder. Put a calendar note a few days before each renewal date. Pausing or delaying a shipment is easier before it ships.
- Drop overlapping supplements. Don’t take a separate multivitamin or B-complex with IM8 unless your doctor advises it. That lowers the risk of very high B12 or other nutrient levels.
- Ease in. If your stomach is sensitive, try half a sachet for the first week, then move to a full serving.
- Mix it properly. Use cold water and a shaker bottle to cut down on sediment.
- Check your medications. Ask your doctor first if you take blood thinners, diabetes medication or thyroid medication.
- Contact support early. Reviews consistently show fast resolutions when customers email care@im8health.com quickly.
With those steps in place, try IM8 with code GET and keep 10% of the cost in your pocket.
Who Should Buy IM8 (and Who Shouldn’t)
IM8 is a good fit if you:
- Already buy several separate supplements and want one simple routine.
- Compete in tested sport and need NSF Certified for Sport products.
- Dislike swallowing pills.
- Are comfortable managing a subscription.
You may want to skip it if you:
- Are on a tight budget or only take a basic multivitamin.
- Have a sensitive gut and don’t want to risk an adjustment period.
- Take medications that interact with vitamin K, berberine or other botanicals, unless your doctor approves.
- Want clinical doses of adaptogens or mushrooms.
If you’re in the first group, Essentials Pro is the place to start, and code GET cuts the price by 10%.

Final Verdict
IM8’s reviews are strong but not spotless. Thousands of customers like the convenience, taste and service. The complaints that do exist cluster around subscriptions, shipping and early digestive changes, and most of these are avoidable or fixable. Expert criticism of proprietary blends and price is fair, so go in with realistic expectations: IM8 is a well-made, convenient foundation supplement, not a miracle product.
