NAC + Glycine — The Two-Part Glutathione Builder
Your body makes less glutathione every decade after 30. NAC and glycine are the two building blocks it runs short on. 1,000mg per serving, two capsules a day.
What does NAC actually do?
N-acetyl cysteine is the rate-limiting precursor your body uses to make glutathione, its primary internal antioxidant. Supplementing it gives the pathway the raw material it runs short on with age.
Why pair it with glycine?
Glutathione is built from three amino acids. Cysteine and glycine are the two that decline. Supplying only one leaves the pathway bottlenecked — the pair is what the published work uses.
Why 1,000mg per serving?
600mg NAC plus 400mg glycine matches the ratio used in clinical research. Most products ship a fraction of that inside a proprietary blend.
What is the guarantee?
Sixty days. If you do not feel a difference, email us and we refund you in full — no return shipping, no forms.
Clinically Dosed. Fully Absorbed.
600mg NAC and 400mg glycine — the pairing used in published research on glutathione restoration. Most brands ship 250mg of NAC alone and call it a day. BioGood Labs delivers both halves at the full dose.
Two Ingredients. Full Doses. Nothing Else.
Most supplements cram ten ingredients into one capsule and underdose every single one. We took the opposite approach: the two amino acids your body actually runs short on, each at the dose the research uses.
N-Acetyl Cysteine 600mg
The rate-limiting precursor for glutathione. Supports antioxidant defense and healthy respiratory function.*
Glycine 400mg
The second amino acid the pathway needs. Also supports sleep quality and collagen production.*
cGMP Manufacturing
Made in a US facility held to pharmaceutical-grade quality control. Every batch.
Third-Party Verified
Independently tested for purity, potency, and heavy metals before it ships.
NAC alone only does half the job. Glycine finishes it.
Glutathione is built from three amino acids, and after 30 your body runs short on two of them. Take NAC by itself and the pathway still stalls. Pair it with glycine and both halves are covered — which is exactly how the clinical work was run.
What Real Customers Are Saying
I started this mostly for the antioxidant side of things and did not expect much. Six weeks in, the thing I notice most is that I am not dragging by mid-afternoon anymore. My husband started taking it too.
I had been taking NAC by itself for about a year. Switching to the pair made a real difference within a month — I sleep harder, and the seasonal congestion I usually fight in spring barely showed up this year.
Honestly bought it because everything else I tried had ten ingredients and I could never tell what was doing what. Two ingredients, full doses, and I can actually read the label. Second bottle now.
Two capsules. That is the routine.
No powders, no timing rules, no changes to your day. Take them with your morning coffee and stay consistent — most people notice the difference somewhere in the first month.

How is this different from taking NAC on its own?
NAC alone supplies one of the two amino acids that decline with age. Without glycine, the glutathione pathway still bottlenecks. Pairing them at a clinical ratio is the entire point of this formula.
When will I start noticing something?
Most people report changes somewhere between week two and week six. Glutathione status rebuilds gradually, so consistency matters more than dose timing.
Is it safe to take with other supplements or medication?
NAC and glycine are both well tolerated and widely studied, but if you take prescription medication — particularly nitroglycerin or blood thinners — check with your doctor first.
Are there any fillers or artificial ingredients?
No. Two active ingredients, a vegetarian capsule shell, and nothing else. No magnesium stearate, no dyes, no proprietary blends.
Is it third-party tested?
Every batch is tested by an independent lab for identity, potency, heavy metals, and microbials. Certificates of analysis are available on request.
What if it does not work for me?
Email support within 60 days and we refund the full purchase price, even on opened bottles. You keep whatever is left.
