Glutathione

Glutathione is a molecule your body produces naturally — made up of three amino acids: glutamine, cysteine, and glycine. It's often called the "master antioxidant" because it's involved in almost every major protective process in your body: neutralizing toxins, repairing DNA, supporting your immune system, and slowing cellular aging.

The problem is your body makes less of it every year — and lifestyle factors like stress, poor diet, and environmental exposure speed that decline up.

Glutathione is a strong fit for anyone prioritizing longevity, detox, or cancer prevention. It's also commonly used by people dealing with chronic fatigue, brain fog, skin concerns, or anyone who wants to support their immune system at a deeper level.

If you're already using NAD+ or Methylene Blue, glutathione pairs directly with both as part of a complete cellular health protocol.

Each order includes a 10ml vial at 200mg/ml — 2,000mg of glutathione total. At the standard protocol of 200mg twice per week, one vial lasts approximately 5 weeks. Your provider will confirm the right dose for you during your consultation.

Glutathione is administered subcutaneously — a small injection just under the skin. The most common sites are the abdomen (at least 2 inches from the navel) or the outer thigh.

Everything you need — syringes, alcohol pads, and full instructions — is included with your order. If you've never done a subcutaneous injection before, your provider can walk you through it.

Yes. Glutathione and NAD+ are highly complementary — both support cellular repair, energy production, and detoxification through different pathways. Many of our longevity patients use them together.

Always disclose everything you're taking during your consultation so your provider can confirm the right protocol for you.

Glutathione is not recommended for individuals who are pregnant or breastfeeding, those with known allergies to sulfur-containing compounds, anyone currently on immunosuppressants or active chemotherapy, or those with severe kidney or liver disease unless under close medical supervision. Your physician will review your full history before prescribing.

Most people tolerate glutathione injections well. The most common experience is mild redness or discomfort at the injection site, which typically resolves quickly.

Less commonly, some people report temporary headaches or mild nausea. If you experience difficulty breathing, swelling, or any signs of an allergic reaction, stop use and seek medical attention immediately.

Yes — always. Your Fierce Health provider will review and approve your protocol, but your primary care physician knows your full medical history. Keeping them informed ensures nothing gets missed and your care stays coordinated.

Yes. Your order includes the medication vial, syringes, and alcohol pads — everything you need to get started. Your physician consultation and ongoing provider access are also included.

As glutathione levels drop with age, oxidative damage accumulates faster than your body can repair it. Restoring those levels helps protect skin elasticity, supports bone density, and slows the internal cellular breakdown that shows up as visible aging. It works at the source, not on the surface.

Your medication is compounded and fulfilled by state-licensed, FDA-regulated pharmacies within our network. Every batch is tested for potency, sterility, pH, and endotoxicity before it ships. You get full pharmacy-grade quality with no guesswork.

Glutathione works on skin at the cellular level. It inhibits the enzyme responsible for melanin production, which reduces dark spots and uneven tone over time. It also clears the oxidative buildup that breaks down collagen and causes premature wrinkling. Results build with consistent use.

Intense exercise generates significant oxidative stress. Glutathione helps your body clear that stress faster, which means less muscle soreness, quicker recovery, and better sustained performance over time. Results may vary.

Most people notice improvements in energy levels and mental clarity within the first 2 to 4 weeks.

Skin changes typically take longer, usually 4 to 8 weeks of consistent use. Individual results depend on your baseline glutathione levels, dosing consistency, and overall health. Results may vary.
