Power Drops — Boost

Made for stepping into the day with drive, without the crash pattern of conventional energy drinks.

1. 01

   L-theanine250 mg

   The 250 mg dose is the one Haskell and colleagues gave with caffeine. The decision to pair the two compounds comes from that literature; the ratio we ended up with does not — see the note above.

   What this does not establish

   The meta-analytic evidence covers acute effects on attention tasks in laboratory settings. It says nothing about a daily ritual sustained over weeks.

   No authorised health claim exists for this compound, so none is made.

2. 02

   Caffeine (anhydrous + guarana)100 mg total

   The best-evidenced stimulant in the category. We use less of it than the combination trials did, which is the single decision that sets this formula apart from them.

   What this does not establish

   A recurring open question in the literature is how much of caffeine's apparent benefit is the relief of withdrawal in habitual users rather than an effect on a rested brain.

   No authorised health claim exists for this compound, so none is made.

3. 03

   N-acetyl-L-tyrosine300 mg

   The tyrosine literature describes effects that appear specifically under stress or sleep loss and are absent in rested participants — an unusually well-characterised boundary condition.

   What this does not establish

   That literature tested L-tyrosine. We use the N-acetyl form, which has different pharmacokinetics. It is a different compound and the results do not automatically transfer.

   No authorised health claim exists for this compound, so none is made.

4. 04

   Taurine500 mg

   Long-standing presence in the category and a substantial human safety literature.

   What this does not establish

   The most cited cognitive finding tested a drink containing taurine and caffeine together, so the contribution of taurine alone cannot be separated out.

   No authorised health claim exists for this compound, so none is made.

5. 05

   Rhodiola rosea150 mg, 3% rosavins / 1% salidrosides

   Standardised to the ratio used in the clinical trials, because with botanicals the extract specification is the thing being tested, not the plant.

   What this does not establish

   The trials are small, mostly from around 2000, and largely conducted on a single standardised extract.

   No authorised health claim exists for this compound, so none is made.

6. 06

   Niacinamide20 mg (125% NRV)

   One of the two compounds in this formula with an authorised claim, and part of why the product can say anything at all.

   What this does not establish

   The authorised wording is the whole of what may be stated. Nothing about focus or drive follows from it.

   What may be stated: Niacin contributes to the reduction of tiredness and fatigue. (authorised health claim, Reg. (EU) 432/2012) The claim may be used only where the product is at least a source of the nutrient — 15% of the nutrient reference value per portion — which this dose supplies.

7. 07

   Vitamin B6 (P-5-P)1.4 mg (100% NRV)

   The second authorised claim carrier in the formula.

   What this does not establish

   As above — the register wording is the limit of what may be said.

   What may be stated: Vitamin B6 contributes to normal psychological function. Vitamin B6 contributes to the reduction of tiredness and fatigue. (authorised health claim, Reg. (EU) 432/2012) The claim may be used only where the product is at least a source of the nutrient — 15% of the nutrient reference value per portion — which this dose supplies.
