What Are the Ingredients in Onnit?

Here are some of the primary active Onnit ingredients:

Whey Protein – It’s a by-product of the cheese-making process and is one of the main ingredients included in dairy products. Like some other proteins, whey is very helpful in building up muscle mass and strength. In addition, it can speed up muscle recovery [1].

Whey protein can also help fill up your stomach and suppress your appetite, possibly leading to weight loss. In addition, it may elevate your metabolism which can promote fat burning. Whey protein helps to lower blood sugar and blood pressure. A study in Nutrients confirmed that whey protein can improve exercise recovery after a strenuous workout [2].

Turmeric – This plant is a common spice, and it has many health benefits. It contains anti-inflammatory agents which can effectively treat the pain and swelling of arthritis. It also has curcuminoids like curcumin which are antioxidants [3].

They help boost the immune system and promote healing in the body. There’s some evidence that it can enhance brain health, improving memory and learning. In addition, it supports heart health and may decrease the risk of developing heart disease.

A systematic review published in the Journal of Medicinal Food found that turmeric is effective in treating arthritis.

5-HTP – This brain chemical is the precursor to the neurotransmitter serotonin, which is involved in mood. 5-HTP can raise positive mood and it may treat depression. In addition, it could also help with other psychiatric conditions like fibromyalgia, and headaches [4].

There’s evidence that this chemical can aid with weight loss by suppressing the appetite. In addition, the boost in mood can decrease emotional eating. 5-HTP also increases melatonin production, which helps improve your sleep quality.

An article in Natural Medicine Journal discussed the many uses of 5-HTP, including in the treatment of depression, psychiatric disorders, and some medical conditions.

 

How Does Onnit Work?

There are many different products in the Onnit line for different health purposes. Most of them are rich in antioxidants, which can eliminate free radicals and lower oxidative stress. This promotes healing in the body and supports a strong immune system. The products are full of other nutrients as well like vitamins and minerals.

Many of the products aim to improve athletic performance, and they include proteins and other muscle-building ingredients which elevate mass and strength. Some products boost nitric oxide which improves blood circulation and therefore sends blood to the muscles.

Other supplements support the joints and include potent anti-inflammatory agents which reduce pain and swelling, via ingredients such as fish oil. An article in Surgical Neurology International recommends natural anti-inflammatory pain relief agents [5].

There are supplement which help with sleep, and also elevate mood by increasing the production of key neurotransmitters like serotonin. In addition, other brain chemicals support brain health and may improve cognitive performance and mental focus.

Finally, there are digestive health products that include enzymes, probiotics and prebiotics which proliferate and feed good bacteria in the gut. This can reduce symptoms like gas and bloating and promote healthier bowel movements. Harvard Health Publishing discussed the health benefits of taking probiotics [6].
