Your first three months

Small daily habit. Results that build.

Four capsules each morning, on an empty stomach. Here's how reviewers describe the first three months.

Every morningBefore food, with water
  • 2 × Glutathione
  • 1 × Berberine
  • 1 × TUDCA
  1. 1

    Week 1–2

    Four capsules before breakfast. Reviewers call them easy to take, with no taste and no after-burps.

  2. 2

    Week 4–8

    Steadier afternoons

    Reviewers describe feeling steadier through the afternoon, with fewer snack raids.

  3. 3

    Week 6

    Skin looks clearer

    Some reviewers mention clearer skin by week six.

    Part of your morning

    By month three it's simply part of the morning, and it's when some people re-check with their GP.

The research

The proof behind every bottle.

Every ingredient in the stack has been tested in people. Here's what the key trial for each one found.

TUDCA · Clinical trial · 2010Insulin sensitivity up about 30% in just four weeks.

20 adults with obesity took TUDCA or a placebo, and placebo changed nothing. The trial used 1,750 mg a day; the stack's serve is 500 mg.Kars M et al., Diabetes, 2010 · View on PubMed

Berberine · Clinical study · 2004Blood fats down by up to a third in three months.

32 adults with high cholesterol. A 2023 review of 18 placebo-controlled trials also found reductions, though smaller.Kong W et al., Nature Medicine, 2004 · View on PubMed

Glutathione · Clinical trial · 2015Daily glutathione lifted the body's own stores.

54 adults over six months. Levels slipped back within a month of stopping, so taking it daily matters. The stack's serve is 2,000 mg, twice the trial's top dose.Richie JP Jr et al., Eur J Nutr, 2015 · View on PubMed

Plan ahead

The 3-bottle stack has a day-45 gap. The 90-Day Supply closes it.

Glutathione is taken at 2 capsules a day, so one bottle lasts 45 days while TUDCA and Berberine last 90. The 90-Day Supply adds a second Glutathione bottle so everything finishes together.

FAQ

Questions, answered.

Something else? Email info@eternalelixir.com.au.

Who is the Metabolic Wellness Stack for?

Adults who want one daily routine for liver and metabolic support, with a powerful antioxidant alongside it.

How do I take it?

Each morning on an empty stomach: 2 Reduced L-Glutathione capsules, 1 Berberine capsule and 1 TUDCA capsule. Always follow the directions on each label. If you are new to these ingredients, introduce one product at a time first.

How long does the stack last?

At 1 capsule a day, as their labels direct, TUDCA and Berberine each last 90 days. Reduced L-Glutathione is 2 capsules a day, so its bottle lasts 45 days and is the one you reorder first. The 90-Day Supply includes two Glutathione bottles, so all four bottles last the full 90 days. Take more than the daily serve and they run out sooner.

Should I choose the stack or the 90-Day Supply?

If you plan to stay on the routine for three months, the 90-Day Supply is better value. It is $25.00 more than the stack and adds a second Glutathione bottle worth $39.99. It saves $37.97 on buying the four bottles separately.

When will I notice a difference?

Reviewers who notice a change usually mention weeks 4 to 8, such as feeling steadier through the day or clearer skin by week six. Glutathione stores build over months, which is why we suggest planning for at least 90 days.

Is this a weight-loss product?

No. This is a metabolic wellness support stack, not a weight-loss product.

Can I take it with medication?

Check with your doctor first. Berberine may interact with several kinds of medicine, including diabetes and other blood sugar medicines, blood pressure medicines, blood thinners (anticoagulants), antibiotics and immunosuppressants. Do not use during pregnancy or breastfeeding unless advised by a qualified healthcare professional.

Can I buy the products separately?

Yes. TUDCA, Berberine and Reduced L-Glutathione are all sold individually. Together they cost $149.97, so the stack saves you $22.98.

How fast is shipping?

We dispatch fast from within Australia. Orders over $100 ship free, and this stack qualifies; below that, standard shipping is $10. Standard shipping takes 3 to 7 business days: metro areas usually 3 to 5, regional areas 5 to 7. Express shipping ($13) is available at checkout.

What if it's not for me?

We offer a 30-day money-back guarantee. Contact us within 30 days of purchase for a full refund. Returns need to be in their original packaging, and return shipping within Australia is paid by you unless the product is faulty.

Can I pay in instalments?

Yes. Pay with Afterpay in 4 interest-free payments of $31.74 for the stack, or $37.99 for the 90-Day Supply. We also take Apple Pay and all major cards (Visa, Mastercard, AMEX).
