Woman over 55 radiating energy, wearing glasses and a beige top against a beige background

Formulated for daily energy after 55

The afternoon slump isn't just age. It's a supply problem you can fix.

After 55 your cells convert nutrients into usable energy less efficiently, and B-vitamin absorption drops at the same time. That's why the day feels heavier than it should. The answer isn't caffeine or a sugar hit. It's giving your metabolism the active nutrients it needs to actually make energy.

Sound familiar?

  • The afternoon hits harder than it used to, and you're running on less than you'd like.

  • You get enough sleep but still wake up feeling like you're behind.

  • Ordinary tasks and workouts leave you more drained than they should.

  • You want steady energy to stay active and independent, not a spike followed by a crash.

Why energy dips after 55

Daily energy naturally becomes harder to sustain after menopause. The biology behind it is specific: your cells convert nutrients into usable energy less efficiently with age, so the same food yields less of the fuel that carries you through the day.

Two further shifts compound it. The absorption of B-vitamins, the nutrients your metabolism runs on, declines with age, at the very moment your cells need them most. And as muscle becomes harder to maintain, the body loses some of the engine that keeps daily energy steady.

None of this is failure. It is a supply problem. Your metabolism is being asked to produce energy with a nutrient supply that no longer matches the demand, which is exactly the kind of gap targeted nutrition is designed to close. The question becomes a precise one: which nutrients, in which forms, at which doses.
Support your energy

Why a better system, not a stimulant

Steady energy is not a single lift. It rests on connected systems: the cellular machinery that regenerates fuel, the metabolism that converts nutrients into usable output, the muscle that keeps the body strong, and the minerals that keep the whole engine running.

That is why caffeine and sugar fall short, and why the formula is built to work as one system. A methylated B-complex, using active forms of B12, B6 and folate, fuels the metabolic pathways that turn food into energy and helps reduce tiredness and fatigue. Creatine supports the cells that regenerate energy during exertion, and the muscle that keeps daily activity feeling lighter. Selenium supports the thyroid side of vitality, and chromium keeps macronutrient metabolism steady underneath it all.

Taken together, they support energy at its source. A stimulant only borrows against tomorrow.
Support your energy

A research project before it was a product

Silvie, from Silver Life, was created in Amsterdam. Our formulas are designed by a team of doctors and longevity researchers with one specific focus: women after 55. Silvie Body did not begin with a formula. It began with a question. What does the post-menopausal body measurably need to feel energised?

The answer was worked out across more than 200 independent studies, with a deliberate bias toward human trials in older adults and women rather than results borrowed from other groups. Every nutrient was then chosen in a specific form for absorption and digestive comfort, and dosed to the evidence. High enough to matter, never higher for the label.

The result replaces a shelf of bottles with one daily sachet. No proprietary blends, no fairy-dusting, every dose disclosed and every form justified.
Start with Silvie Body

Most supplements are dosed for the average adult. You're not the average adult anymore.

Silvie formulas are built for women after 55, with doses drawn from human trials in older women, not borrowed from studies on animals or 30-year-olds.

Why Silvie is different

One system, not a shelf of supplements

Most routines stack three or four products with unclear doses. Silvie replaces the guesswork with a single formula.

Every nutrient. A specific form, a disclosed dose.

Only researched ingredients, no fairy-dusting. Tap any nutrient to see what it does, the form we selected, and why we set the dose where we did.

Collagen is the most abundant structural protein in the human body. As a source of protein, it contributes to the maintenance of normal bone and the growth and maintenance of muscle mass.

Form: Hydrolysed peptides, pre-broken down for maximum absorption.
Why this dose: A research-informed dose that supports structure and bone mass, easy to take daily.

Creatine is the body's primary molecule for rapid energy regeneration. When combined with regular resistance training, a daily 3g intake is scientifically proven to enhance muscle strength in adults over the age of 55 by increasing the availability of cellular fuel.

Form: Monohydrate, micronized so it dissolves cleanly and sits easier on the stomach.
Why this dose: The research-informed daily dose, enough to saturate muscle stores without the bloating of loading doses.

Vitamin D functions as a pro-hormone, regulating calcium absorption. This regulation contributes to normal blood calcium levels and the maintenance of normal muscle function. Crucially, it helps reduce the risk of falling associated with poor balance, coordination and muscle weakness in women 55+.

Form: Cholecalciferol, the bioactive form your skin makes, stronger than D2.
Why this dose: The physician-recommended level for older adults, well above the baseline minimum.

While Vitamin D helps absorb calcium, Vitamin K2 helps direct it. It acts as an essential helper molecule for proteins that contribute to the maintenance of normal bone. Emerging research highlights the synergy between D3 and K2 in optimizing skeletal integrity in ageing adults.

Form: MK-7, which stays active in the body for days, unlike synthetic MK-4.
Why this dose: A high-potency dose, informed by landmark research.

Calcium is the essential mineral foundation of the skeletal system. Beyond its authorized role in maintaining normal bone, it is critical for normal muscle function and neurotransmission (the signaling between brain and body).

Form: Citrate, which absorbs well even with low stomach acid, unlike carbonate.
Why this dose: A moderate 31% NRV top-up that supports bone density while keeping a healthy balance with your dietary intake.

Vitamin C is an essential helper molecule for the enzymes that build collagen. It contributes to normal collagen formation for the normal function of bones, cartilage, and skin. Additionally, it protects cells from oxidative stress.

Form: Calcium ascorbate, a buffered, non-acidic form that stays gentle on the stomach.
Why this dose: 313% NRV, the saturation level needed for collagen synthesis and antioxidant defense, kept gentle by the buffered form.

Thiamine (B1), Riboflavin (B2), Niacin (B3), and Pantothenic Acid (B5) contribute to normal energy-yielding metabolism, effectively converting nutrients into the fuel needed for muscle and brain function.

Form: Active coenzyme forms, ready for the body to use immediately.
Why this dose: Physiological doses for steady enzymatic support, avoiding the itching and nausea that mega-doses can trigger.

Vitamin B6 is essential for producing neurotransmitters, the chemical messengers that allow your brain cells to "talk" to one another. These include serotonin (which regulates your mood and sense of well-being) and dopamine (which supports your motivation and focus). By supporting these messengers, Vitamin B6 contributes to the reduction of tiredness, normal psychological function, and the regulation of hormonal activity.

Form: Pyridoxal-5-phosphate, the active form that needs no liver conversion.
Why this dose: The level used in landmark longevity research.

Folate is required to recycle homocysteine, a natural byproduct that can rise with age. If left unmanaged, high levels of this byproduct may impact the delicate structures of your heart and brain. Folate converts it back into useful nutrients. Folate also contributes to normal psychological function, blood formation, and the reduction of tiredness and fatigue.

Form: Folate as 5-MTHF, which works even with the common MTHFR gene variation.
Why this dose: The level used in landmark longevity research.

Absorption efficiency of B12 decreases significantly with age due to reduced stomach acid. It contributes to normal energy-yielding metabolism, red blood cell formation, and the normal functioning of the nervous system.

Form: Methylcobalamin, the active form that bypasses age-related absorption gaps.
Why this dose: A research-informed high-potency dose, to work around age-related absorption changes.

Chromium contributes to the maintenance of normal blood glucose levels, supporting steady energy regulation and metabolic health.

Form: Picolinate, more stable and better absorbed than standard chromium salts.
Why this dose: A safe maintenance dose at 50% NRV, enough to support glucose metabolism without interfering with other minerals.

Selenium contributes to normal thyroid function (the master regulator of metabolism) and the protection of cells from oxidative stress.

Form: Selenium yeast, a food form that is stored better in the body.
Why this dose: A 73% NRV dose that supports antioxidant and thyroid function without accumulation.

Copper supports the maintenance of normal connective tissues. Together with Manganese, it helps maintain the structural mesh that supports joints and bones.

Form: Bisglycinate, more stable and better absorbed than copper sulfate.
Why this dose: Calibrated to 90% NRV to balance our zinc, preventing the deficiency high-dose zinc can cause.

Manganese is a trace mineral that acts as a helper molecule for enzymes involved in tissue repair. It contributes to the normal formation of connective tissue and protects cells from oxidative stress.

Form: Bisglycinate, which survives digestion so it is actually absorbed.
Why this dose: A moderate 35% NRV dose for safe, long-term connective tissue support without accumulation.

Really good!

Anne L.

The package took almost a week to arrive. The products are nice.

Thomas from Silvie

Hi Anne. We apologize for the delay, it's not normal. We have just changed our carrier, we hope it doesn't happen again. We have also sent you a gift card :)

Sophie D.

It dissolves very well. The taste is surprising, very faint, almost tasteless. I drink it with a home-made smoothie.

Marianne V.

I love it! It replaces everything I was using before and it's actually simple.

Nathalie C.

Good quality but a bit expensive

Elizabeth G.

I had never heard of this brand before so I was worried it was fake. But I'm very surprised, the products look really nice and I've been using it every day for 3 weeks, I can feel a difference

Thomas from Silvie

Thank you for the kind words Elizabeth. We're very real :)

Claire T.

Le site web n'est pas facile a comprendre mais j'ai été surprise par les produits, ils sont top.

Thomas from Silvie

Merci Claire. On travaille pour améliorer le site.

Monica A.

A friend of recommended it, I was curious because I already take creatine and collagen and they don't taste good. The taste is strange at first but better than my previous powders. I think I will buy it again.

Thomas from Silvie

Thank you Monica, it means a lot to us.

Your questions, answered

Before you decide — the questions we hear most.

What if it doesn't work for me?

Every order is covered by a 30-day money-back guarantee. If it's not right for you, opened or unopened, contact us within 30 days of delivery and we'll refund the product price and standard delivery. One claim per customer. Email us and we'll guide you through it.

Is this like caffeine or an energy drink?

No. There are no stimulants. It works by supporting your metabolism with active, methylated B-vitamins and creatine, so the energy comes from your own cells working better rather than from a temporary lift you pay for later.

Can I take it with my medication, HRT or thyroid treatment?

Silvie Body is a food supplement, not a medicine, and is designed to complement HRT and GLP-1 protocols. It contains Vitamin K2 and Creatine, so if you take anticoagulants such as Warfarin or have kidney disease, consult your doctor before use. Because calcium can affect absorption, keep Silvie Body at least 4 hours apart from thyroid medication (Levothyroxine) or bone medication (bisphosphonates), and at least 2 hours apart from antibiotics. If you are pregnant, breastfeeding or have a medical condition, speak with your doctor or pharmacist first.

How long until I notice a difference?

Energy is often one of the earliest things women notice, many within the first week or two. It builds as consistent daily use keeps your nutrient levels topped up. The 30-day guarantee gives you time to judge it properly.

What's inside, and are there allergens?

Every nutrient, form and dose is fully disclosed in the ingredients section above and on the label. No proprietary blends. Silvie Body contains Fish (marine collagen). It is gluten-free and dairy-free. If you have a known fish allergy, do not use it, and check the label for any other allergy before use.

When and how do I take it?

One daily sachet in the morning. Mix the powder with at least 330 ml of water, milk or yoghurt, ideally with a meal containing some fat to help absorb the Vitamin D3 and K2. Because the formula contains creatine, drink plenty of water across the day, around 2 to 3 litres. It can be mixed with Silvie Body Pro.

Where do you ship, and how fast?

Free standard shipping across the EU, UK and Switzerland. Orders ship within 1 to 3 business days. Delivery typically takes 2 to 7 business days in the EU and 4 to 10 to the UK, with tracking by email.

Try Silvie Body for 30 days, risk-free.

Every dose disclosed, designed for women after 55. If it's not right for you, we'll refund you — no forms, no fuss.
