ProHealth Pure Glycine 1000 mg and Pure N-Acetyl Cysteine 600 mg, 120 Capsules Each (2-Pack)

Key Ingredients and Their Roles

Glycine (1000 mg per capsule): This non-essential amino acid, conditionally essential in certain situations, is a primary building block of collagen—the body's most abundant protein. It supports skin, bones, tendons, and ligaments, and acts as a neurotransmitter in the central nervous system to promote calmness and improve sleep quality. Glycine also contributes to the synthesis of glutathione, creatine, and bile acids, making it a versatile nutrient for overall health.

N-Acetyl Cysteine (600 mg per capsule): NAC is a modified form of the amino acid cysteine and a direct precursor to glutathione, the body's master antioxidant. By boosting glutathione levels, it helps neutralise free radicals, supports the liver's natural cleansing pathways, and may assist in maintaining respiratory health by thinning mucus. NAC has a history of clinical use for acetaminophen overdose and is widely researched for its neuroprotective and anti-inflammatory properties.

Both ingredients are supplied in their pure, unadulterated forms to insure maximum bioavailability and effectiveness.

What Is the ProHealth Glycine + NAC Stack?

This stack brings together two powerhouse nutrients that are widely recognised for their roles in supporting longevity and overall wellbeing. Glycine, the simplest amino acid, is a building block for proteins and a key player in neurotransmitter function and collagen synthesis. NAC, a precursor to the master antioxidant glutathione, helps maintain the body's natural defence against oxidative stress. When combined, they create a synergistic stack that many health enthusiasts include in their daily routines for cellular health and vitality.

Each pack contains 120 capsules of Pure Glycine (1000 mg per serving) and 120 capsules of Pure NAC (600 mg per serving), providing a convenient two-month supply. Both supplements are manufactured in the USA and undergo rigorous third-party testing to insure purity and potency, with lab results published online for full transparency.

Benefits of This Longevity Stack

Glycine and NAC each offer distinct benefits that complement one another. Glycine is involved in the synthesis of glutathione itself, alongside NAC, making this stack a comprehensive approach to supporting the body's antioxidant capacity. Glycine also supports healthy sleep quality, cognitive function, and joint health by contributing to collagen production. NAC helps replenish glutathione levels, which naturally decline with age, and may support respiratory health and cleansing pathways.

By taking these two supplements together, you may help maintain a balanced methylation cycle—glycine plays a role in methylation while NAC supports homocysteine regulation. This stack is particularly appealing to those focused on healthy ageing, as it addresses multiple aspects of cellular maintenance and stress response. Many users report feeling a difference in their energy levels and overall sense of wellbeing when incorporating this stack into their regimen.

Who Should Consider This Supplement Stack?

This stack is suitable for adults looking to support their body's natural antioxidant defence and promote healthy ageing. It may be especially beneficial for individuals who:

• Are interested in longevity and cellular health.
• Want to support their body's cleansing processes.
• Seek to maintain healthy glutathione levels as they age.
• Are looking for foundational support for sleep, joints, and cognitive function.
• Prefer simple, pure ingredients without complex blends or fillers.

As always, it is a good idea to consult with a healthcare professional before starting any new supplement regimen, particularly if you are pregnant, nursing, have a medical condition, or take prescription medications.

FAQs About Glycine and NAC

Can I take glycine and NAC together?

Yes, they are often taken together as a stack because they work synergistically to support glutathione production and overall cellular health. Many people take them at the same time, either with or without food.

What is the recommended dosage?

The typical dosage is one capsule of glycine (1000 mg) and one capsule of NAC (600 mg) per day, or as directed by your health care provider. Since this pack contains 120 capsules of each, it provides a two-month supply at one capsule per day.

Are there any side effects?

Both glycine and NAC are generally well-tolerated. Some individuals may experience mild digestive discomfort, especially when starting NAC. Glycine may cause drowsiness in some people, so it is often taken in the evening. As with any supplement, it is best to start with a lower dose to assess tolerance.

Can I take this stack with other supplements?

This stack pairs well with other foundational supplements like vitamin C, selenium, and zinc, which also support glutathione function. Always consult with a healthcare professional before combining multiple supplements.

Always read the labelled and follow the directions for use.
