During perimenopause and menopause, estrogen decline slows your skin's collagen production, weakens its barrier, and speeds up bone loss — three specific, documented changes most supplements never address together, let alone at the right dose. Surface supports collagen production and barrier function. Structure supports bone density. Both dosed to the levels the actual research used, not a diluted version of it.

Yes — every batch of Surface and Structure is independently tested for purity and potency before it ships, so you're not just taking our word for the dose on the label.

Surface isn't — its collagen peptides are bovine hide-derived, which is what the underlying peptide-bioavailability research is based on. Structure doesn't contain animal-derived ingredients, but check the full label if you're following a strict vegan diet.

Yes — Surface and Structure are formulated with no overlapping ingredients, so they're safe to take together as one system. If you're also taking other medications or supplements, especially HRT, talk to your doctor before combining anything new.

Most women don't experience side effects at these doses, since every ingredient is used at levels already studied in clinical trials. Mild digestive adjustment in the first week or two is possible, especially with the 10,000mg collagen dose in Surface. If anything feels wrong, stop and talk to your doctor.

We don't recommend Surface or Structure during pregnancy or nursing. Neither has been studied in that population, and both are formulated specifically for the hormonal profile of perimenopause and menopause, not pregnancy. Talk to your doctor before starting any new supplement in either case.

[PLACEHOLDER — do not publish a specific timeframe until confirmed. Preorder units are expected to ship in November; standard shipping times after the preorder period need to come from your actual fulfillment setup, not an estimate.]

Yes — you'll receive a tracking link by email as soon as your order ships.

Every order is covered by a 90-day money-back guarantee. If it's not right for you, contact us for a full refund — no questions asked.

Yes — Nutraeden's formulas are built specifically around the hormonal mechanisms of this transition. If you're not in that window, a general wellness supplement may be a better fit.

Genistein and resveratrol, two ingredients in Structure, are phytoestrogen-adjacent — that's part of why they're studied for postmenopausal bone support. No clinical trial has tested their combined estrogenic load. If you have a personal or family history of estrogen-sensitive cancer, please talk to your doctor before starting Structure.

There's no known conflict, but neither Surface nor Structure has been specifically studied alongside hormone replacement therapy. If you're on HRT or considering it, tell your doctor you're taking Structure specifically — its two bone-density ingredients interact mildly with estrogen pathways.

Collagen synthesis and barrier repair are gradual — most women notice skin changes starting around week 8, with more consistent results by week 12. Bone density is a longer process: the clinical trials behind Structure's core ingredients ran 12 to 24 months to show measurable density gains. We won't pretend that timeline is faster than it is.

Surface addresses your skin — collagen production and barrier function. Structure addresses the bone underneath your skin, a separate mechanism entirely. They're built to work together as one system, but you can start with just one if you'd rather address a single side first.
