Good Day Multivitamin Review: Is the $50 Sachet Worth It?
Good Day is an Australian supplement brand that has built a genuine following — 1,585 reviews at 4.9 stars is not easy to fake. The product is a daily multivitamin in a powder sachet format: mix it with water, drink it, done. The tagline is "It's the least you can do."
At $49.95 AUD for 30 sachets, it costs roughly $1.65 per day. That's not cheap for a multivitamin, but it's not in AG1 territory either. The question is whether the formula justifies the price.
Here's what's actually in it.
What's in Good Day: The Full Ingredient Breakdown
Good Day contains 12 active ingredients per sachet:
| Ingredient | Amount | What It Does |
|---|---|---|
| Turmeric (Curcuma longa) extract | 200 mg (from 4g dry rhizome) | Anti-inflammatory, joint support |
| Rhodiola Rosea extract | 120 mg (from 960mg dry root) | Adaptogen — stress and fatigue |
| Vitamin B1 (Thiamine) | 5 mg | Energy metabolism |
| Vitamin B2 (Riboflavin) | 5 mg | Energy metabolism, cell function |
| Vitamin B3 (Nicotinamide) | 16 mg | Energy, DNA repair |
| Vitamin B5 (Pantothenic acid) | 10 mg | Hormone synthesis, energy |
| Vitamin B6 (Pyridoxine) | 5 mg | Protein metabolism, mood |
| Folinic acid (active folate) | 400 mcg | Cell division, DNA synthesis |
| Methyl B12 (Mecobalamin) | 15 mcg | Nerve function, red blood cells |
| Vitamin C (Ascorbic acid) | 100 mg | Immune function, antioxidant |
| Magnesium citrate | 420 mg elemental | Muscle, nerve, sleep, energy |
| Zinc citrate | 14 mg elemental | Immune function, wound healing |
Notably absent: Vitamin D, Vitamin A, Vitamin E, iron, calcium, iodine, and omega-3.
What Good Day Gets Right
The B-vitamin complex is genuinely well-formulated
Most cheap multivitamins use the cheapest forms of B vitamins — folic acid instead of folate, cyanocobalamin instead of methylcobalamin. Good Day uses folinic acid (an active, bioavailable form of folate) and mecobalamin (methyl B12, the most bioavailable form). This is a meaningful upgrade over supermarket multivitamins and reflects real formulation effort.
The B-vitamin doses are also sensible — not megadoses that your body will simply excrete, but amounts that cover daily requirements without excess.
The magnesium dose is substantial
At 420 mg of elemental magnesium from magnesium citrate, Good Day provides a genuinely therapeutic dose. Most multivitamins include token amounts of magnesium (50–100 mg) that barely move the needle. Magnesium citrate is also one of the better-absorbed forms. This is one of the stronger aspects of the formula.
Rhodiola Rosea at a reasonable dose
Rhodiola is an adaptogen with reasonable evidence for reducing fatigue and improving stress resilience. The 120 mg extract dose (standardised from 960 mg dry root) is within the range used in clinical studies. It's not a miracle ingredient, but it's a legitimate inclusion at a legitimate dose.
The format is genuinely convenient
The sachet format is a real advantage. You don't need to remember to take a pill — you mix it with water and drink it. The passionfruit flavour is consistently praised in reviews. For people who struggle with pill fatigue, this is a meaningful practical benefit.
What Good Day Gets Wrong (or Misses)
No Vitamin D
This is the most significant omission. Vitamin D deficiency is one of the most common nutritional deficiencies in the world — estimates suggest 1 in 5 adults are deficient, and the figure is higher in countries with limited sunlight. Vitamin D supports immune function, bone health, and mood. Its absence from Good Day is a notable gap, particularly for an Australian product where indoor lifestyles mean deficiency is more common than people assume.
If you're taking Good Day as your primary supplement, you'll need to add a separate Vitamin D supplement.
No Vitamin A, E, or iodine
Good Day markets itself as a complete daily multivitamin, but it's missing several nutrients that appear in standard multivitamins. Vitamin A supports vision and immune function. Vitamin E is an antioxidant. Iodine is critical for thyroid function and is commonly deficient in people who don't eat fish or dairy regularly. These aren't deal-breakers, but they mean Good Day is not a true all-in-one multivitamin.
The turmeric dose is modest
Turmeric is listed first on the label, which gives it visual prominence. But 200 mg of turmeric extract is a relatively modest dose — most clinical studies on curcumin (the active compound in turmeric) use 500–1,500 mg of extract, often with added piperine (black pepper extract) to improve absorption. Good Day contains no piperine. The turmeric inclusion is not meaningless, but it's not a therapeutic dose.
The price per nutrient is high
At $49.95 for 30 sachets, you're paying $1.65 per day for a formula that covers B vitamins, magnesium, zinc, vitamin C, rhodiola, and turmeric. That's a reasonable combination, but you could build a similar stack for less:
| Option | Monthly Cost | What You Get |
|---|---|---|
| Good Day | ~$50/month | B vitamins, Mg, Zn, C, Rhodiola, Turmeric |
| Thorne Basic Nutrients + Mg Glycinate | ~$35/month | Full multivitamin + therapeutic Mg dose |
| Blackmores Executive B + Mg + Zn | ~$25/month | B complex, Mg, Zn, C separately |
The convenience premium is real — sachets are easier than multiple pills — but it's worth knowing what you're paying for.
Who Is Good Day Best For?
Good Day is a well-made product that suits a specific type of person: someone who wants a convenient, pleasant-tasting daily supplement that covers the B-vitamin complex, magnesium, and zinc without having to manage multiple bottles. The formulation quality is above average — the use of active B12 and folate forms is a genuine differentiator from supermarket multivitamins.
It is not the right product for someone who:
- Needs Vitamin D supplementation (which is most people)
- Wants a true comprehensive multivitamin covering A, E, iodine, and other micronutrients
- Is price-sensitive and wants maximum nutritional coverage per dollar
Our Verdict
Good Day is a legitimately good product — but it's not a complete multivitamin. It's better described as a B-vitamin complex with magnesium, zinc, vitamin C, and two adaptogenic herbs in a convenient sachet format. The formulation quality is high, the format is genuinely practical, and the reviews reflect real user satisfaction.
The main caveat: if you're taking Good Day as your only supplement, you'll almost certainly still need to add Vitamin D separately. For most people, that means Good Day works best as part of a stack, not as a standalone solution.
Rating: 4/5 — Strong formulation, convenient format, above-average ingredient quality. Docked one point for the missing Vitamin D and the modest turmeric dose relative to the price.
Where to Buy Good Day
Good Day is available directly from the brand's website at $49.95 AUD for 30 sachets, with a 10% subscription discount bringing it to $44.96/month.
If You Want Alternatives
Best Complete Multivitamin: Thorne Basic Nutrients
Covers the full spectrum including Vitamin D, A, E, and iodine, with the same commitment to bioavailable forms (methylfolate, methyl B12). More comprehensive than Good Day but in capsule form.
Best Budget Option: Blackmores Executive B
A solid B-vitamin complex at a fraction of the price. Doesn't have the adaptogens or the sachet format, but covers the core B-vitamin bases reliably.
Best for Magnesium Specifically: Magnesium Glycinate
If the magnesium dose is the main reason you're considering Good Day, a standalone magnesium glycinate supplement provides a similar or higher dose at lower cost, with glycinate being the best-tolerated form for sleep and relaxation.
