Layer identifies the nutritional considerations associated with your long-term treatment, and offers you the support that matches it.
For each of the treatments we support, research describes a deficiency and explains why it sets in. Alongside, the symptoms that the people concerned report. The journal covers every case, with its sources.
Statins inhibit HMG-CoA reductase, upstream of both cholesterol and coenzyme Q10. Folkers measured this drop in Q10 in humans as early as 1990 (PNAS).
Read the studyA deficit associated with muscle pain and weakness on statins (Marcoff and Thompson, JACC, 2007): heavy legs, aches that come from no effort.
Metformin hampers the absorption of vitamin B12 in the gut. A controlled trial measured an average 19% drop after several years (de Jager, BMJ, 2010).
Read the studyA deficiency linked to nerve damage: tingling in the hands, shortness of breath, memory that catches.
By lowering stomach acidity, PPIs reduce the absorption of magnesium. An FDA warning in 2011, confirmed by a meta-analysis (Cheungpasitporn, Renal Failure, 2015).
Read the studyA shortfall tied to night cramps; on the iron side, nails that break and hair that falls more.
On oral contraception, a review of the literature describes increased needs for folate, B2, B6, B12 and zinc (Palmery, 2013).
Read the studyReserves that dwindle, cycle after cycle: mood swings, reactive skin, soft nails.
Beta-blockers curb the release of evening melatonin: a randomised trial measured it in healthy volunteers (Stoschitzky, 1999).
Read the studyHence frequent sleep problems: longer to fall asleep, dips in energy early in treatment.
Each box is designed for a specific treatment and what it changes on the nutrition side. To be taken in addition to yours, never in its place. Nutritional support, not a medication.

You could buy vitamin B12, magnesium or coenzyme Q10 separately. Three questions remain: which form, which dose, and which ones for your precise treatment? Layer answers them for you.
We start from your precise medication, not from a formula meant for everyone.
For each nutrient, we choose the form that research favors.
We dose each active ingredient at the level research considers useful.
A single one replaces the pile of bottles.
And behind every box, the whole platform
Brand name, generic, molecule: the 8,193 medications sold in France are indexed. For each one, we summarise what we know, with the sources. The journal takes over when you want to go further.
