Most supplements are a guess. Including the ones you're probably taking right now.

The multivitamin on your shelf was formulated for a statistical average that doesn't exist - a theoretical person with theoretical deficiencies. It wasn't built for a 34-year-old who trains five days a week and has been running on four hours of sleep since their second kid arrived. It wasn't built for you at all.

The "personalised" supplement brands aren't much better. A quiz asking "how's your energy?" can't tell you your ferritin is 22 when it should be 68. Only a blood test can do that.

Better You exists because the only way to build a supplement that actually works for your body is to measure your body first.

Your collection kit arrives within 1–2 business days of ordering. Inside: a Tasso+ device, collection tubes, alcohol wipes, a prepaid return bag, and step-by-step instructions.

You press the Tasso against your upper arm. A ring of micro-needles - too fine to feel like a traditional needle - draws a small volume of blood into the device over about five minutes. Most people describe the sensation as a light pressure, not pain. No clinic. No phlebotomist. No appointment.

You drop the sample in the prepaid return bag, post it at any Australia Post box, and you're done.

What's in the kit:

• 1× Tasso+ collection device
• 1× collection tubes with barcoded labels
• Alcohol wipes + bandaid
• Prepaid return satchel (express)
• Illustrated instruction card

Your sample arrives at our partner lab - a NATA-accredited Australian pathology facility operating under ISO 15189, the international standard for medical laboratories. It's the same accreditation used by hospitals and major clinical pathology services.

Your blood is processed by registered laboratory scientists. Not an app. Not a machine in someone's garage. The same people who run samples for hospitals are running yours.

What we measure - 30+ biomarkers across six domains:

• Iron status: ferritin, serum iron, transferrin saturation
• Vitamins: D, B12, folate
• Minerals: magnesium, zinc
• Metabolic: HbA1c, fasting glucose, lipid profile (total cholesterol, LDL, HDL, triglycerides)
• Organ function: liver enzymes (ALT, AST, GGT), kidney markers (creatinine, eGFR, urea)
• Inflammation & thyroid: CRP, TSH, full blood count

Every marker is measured against both the standard "reference range" used in clinical pathology and the optimal range associated with performance, recovery, and long-term health — which is usually much narrower.

Once your results come back, your formula is built. Not chosen from a pre-made catalogue. Built.

Every suboptimal marker becomes a target. Every target becomes a specific ingredient at a specific dose in a specific sachet at a specific time of day.

What makes it different from a multivitamin:

• Bioavailable forms only - methylated B-vitamins (not cyanocobalamin), chelated minerals (not oxides), D3 with K2 (not D2 alone)
• Pharmaceutical-grade - purity and potency verified by third-party testing before every batch
• TGA-listed - every ingredient complies with Australian therapeutic goods standards
• No proprietary blends - every ingredient and dose is disclosed
• AM/PM split - nutrients separated by absorption pathway and circadian function

Ninety days is the minimum window needed to see measurable change in most biomarkers - ferritin, vitamin D, B12, inflammation, HbA1c all move on that timeline.

On day 80 of your cycle, a fresh Tasso kit ships automatically. You collect, post, and receive a new report that places your latest numbers beside your previous results - colour-coded green / yellow / red, with a trend line drawn across each marker.

Then your formula recalibrates. Markers that have corrected get lower doses or drop out entirely. New markers come into focus. Your formula at month 12 looks nothing like your formula at month 3 - because your body at month 12 isn't what it was at month 3.

This is the part no shelf supplement can ever do. A bottle doesn't know your ferritin climbed from 22 to 68. A Better You formula does.
