Pros
- No proprietary blends
- Effective serving schedule – 3 times per day prolongs the beneficial effects
- 5-HTP should curb your appetite slightly
- Green Tea works to boost your metabolism, burning a hundred or so extra calories per day
Cons

- Lacks core fat burners such as cayenne pepper and vitamin D
- Not as effective in hunger reduction as other leading fat burners
HUM Skinny Bird Review at a Glance:
HUM Skinny Bird is not a terrible supplement, but it’s missing far too many important ingredients for us to recommend it as one of the best fat burners. It may slightly reduce your appetite thanks to 5-HTP and elevate your energy thanks to green tea but that’s about as good as it gets. If you’re looking to achieve substantial weight loss results, you’re better off doing more research before rushing into this one.

About HUM Skinny Bird
HUM Skinny Bird is a natural over-the-counter dietary supplement that helps you:
- Curb appetite
- Balance blood sugar levels
- Helps manage stress-induced binge eating
Skinny Bird contains ingredients such as 5-HTP and chromium which help to reduce appetite, along with green tea extract which works to increase your metabolic efficiency.
To be more precise, HUM says Skinny Bird can help you consume 230 fewer calories per day. If it can really do this, it will be hugely beneficial as you will be more likely to meet your daily calorie intake.
So, how will HUM Skinny Bird work for you? Let’s have a closer look.
HUM Skinny Bird Ingredient Analysis

Skinny Bird consists of the following active ingredients:
- Chromium picolinate – 200mcg
- Caralluma Fimbriata extract – 333mg
- 5-HTP – 100mg
- Green Tea Extract – 66mg (33mg of which is caffeine)
The ingredients themselves look good for the most part. You have a clear and transparent ingredient label so you know their dosages. This makes it easy for us to assess how effective and safe these ingredients are.
However, there are some problems with HUM Skinny Bird’s formula, namely the lack of other important ingredients for weight loss. Let’s have a closer look.
Chromium picolinate – 200mcg
Chromium Picolinate is a trace mineral. It helps your body regulate glucose and insulin metabolism. By supplementing chromium, you may notice a reduction in food cravings from more balanced blood sugar levels. However, this effect is not strong nor noticeable if you aren’t already deficient in chromium. The mineral is typically found in grains. So if you already eat enough grains, then you won’t benefit much from chromium supplements.
Caralluma Fimbriata extract – 333mg
This is an odd one. It is a type of red cactus native to India. It grows in many areas including along the roadsides. There is not much data for us to recommend this ingredient as an effective weight loss aid. Examine states that there is only one human study that tested Caralluma Fimbriata’s effect on weight loss, and it found that the plant may help reduce your appetite slightly. However, the study used a dosage of 1000mg of a highly concentrated 14:1 Caralluma Fimbriata extract. This is far higher than what is in HUM Skinny Bird.
5-HTP – 100mg
5-HTP is a molecule that turns to serotonin in your brain. Serotonin is a neurotransmitter that regulates many functions in our body, including your mood and appetite. 5-HTP is a great ingredient to supplement occasionally when you know you’re going to be tempted with food. However, it’s best to cycle 5-HTP on and off every few weeks to avoid potential side effects.
Green Tea Extract – 66mg (33mg of which is caffeine)
Green tea extract is an excellent fat burner in HUM Skinny Bird. It triggers your metabolism’s activity, making you burn more fat as a result. It helps to convert your fat stores into energy along the process, which helps you have better workouts as an added bonus.
Our Commentary on HUM Skinny Bird’s Formula
Skinny Bird has a couple of great ingredients for weight loss, such as green tea extract and 5-HTP. But that’s about as good as it gets. Glucomannan, cayenne pepper extract, ashwagandha, and other core ingredients for weight loss are missing from Skinny Bird.
Will it help you lose weight? To an extent, yes. This formula can get you results if you’re consistent with your diet and training long-term. But it’s definitely not the best one we’ve seen.
How to Use HUM Skinny Bird
HUM Skinny Bird has an excellent serving schedule – 1 capsule, 3 times per day, 30 minutes before each meal. This is a great way to take a fat burner as it maintains the beneficial effects throughout the day, rather than just taking everything all at once (like many ineffective fat burners).
Side Effects
HUM Skinny Bird is unlikely to give you negative side effects if you’re healthy. The ingredients, for the most part, are well-researched and are known to be safe. The only exception is 5-HTP which affects your serotonin levels. Taking it long-term may lead to side effects in people taking medications such as SSRIs. In this case, you need to talk to your doctor before taking Skinny Bird.
What do Others Say?

HUM Skinny Bird is a relatively new supplement to hit the market. As such, impartial reviews can be tricky to find. On Amazon, it has an average score of 3.5/5, which is pretty bad. Here are a few reviews from there;
“It’s an alright product if you’re trying to control eating between meals but I don’t see much difference from when I started taking them to now almost a month later.” – Amazon Customer
“I love Skinny Bird SO MUCH, and have taken it on and off for about 18 months. I always lose a few pounds.
It helps curb my appetite for sure – but in a good way (meaning, i don’t feel hungry!) It’s made from caralluma, and also has chromium inside. I just follow the instructions, take 3 pills a day a bit before meals – so spread it over the day. I’ve tried products from other companies, and they have never worked so well as Skinny Bird. PS – it is very smart name too, makes me laugh. I know from a friend that in the UK they sometimes call a girl a ‘bird’ as slang. :)” – Kayla
“I took this 30 minutes before dinner, had 5 bites of food before I started vomiting. I couldn’t hold water down and fortunately my neighbor is a Dr and pointed out that the HTTP 5 interacts very badly with antidepressants. I was severely dehydrated but a good tip is to take small sips until you can swallow water properly again. I completely untrust how little info there is on this and shame on me for not consulting my psychiatrist first.” – Veronika Lee
Pricing, Availability, and Other Things to Consider
Skinny Bird costs $40 on HUM Nutrition’s website. The price can vary depending on where you buy it. It is also available at Sephora and on Amazon.
