Supporting muscle and bone health after 40 comes down to a short list of well-studied ingredients — creatine, HMB, vitamin D3, calcium, and magnesium — taken consistently rather than heroically. Both muscle and bone naturally decline with age, and the supplement industry has finally started building formulas around that specific reality instead of just repackaging bodybuilder products.
Solaray, a supplement maker that has been sourcing ingredients globally since 1973, now fields several formulas aimed squarely at strength, endurance, and bone support. Here is how the key ingredients work together and which products deliver them.
Why muscle and bone deserve one strategy, not two
Solaray's own framing on its Creatine + MBP formula puts it plainly: bone and muscle strength are pillars of longevity, and both decrease with age. That pairing is the insight. Muscles pull on bones; bones anchor muscles. Supporting one without the other is half a plan.
This is why the most interesting formulas for people over 40 are combination products: creatine paired with a bone-support ingredient, or HMB paired with vitamin D3 and calcium. You get the muscle-maintenance side and the skeletal side in a single daily habit, which is the kind of simplicity that actually survives a busy schedule.
Format matters for adherence, too. Solaray splits its strength lineup between powders and capsules on purpose: the creatine formulas are one-scoop powders that vanish into a drink, while the magnesium options are two-VegCap servings that live happily next to a toothbrush. Pick the delivery format you will not skip, because the best-designed formula in the world does nothing from inside the cupboard.
Creatine + MBP: the longevity-focused creatine
Consistency also beats intensity here. The people who report the most from routines like this are rarely the ones with the most products; they are the ones who take the same two or three formulas daily for months. Design your stack so it survives your worst week, not your best one.
Creatine is best known from gym culture, but Solaray's Creatine + MBP is built for a different audience. Each serving delivers 8 g of creatine monohydrate to support bone and muscle health in aging populations, muscle growth, and muscle recovery after exercise, alongside 40 mg of MBP Whey Fraction — a clinically studied ingredient supporting bone mineral density plus bone health and maintenance — and 500 mg of l-leucine for additional targeted support.
The unflavored powder mixes into water or any beverage, one scoop at a time, which makes it easy to fold into a morning coffee-and-supplements routine.

HMB + Vitamin D3: endurance and the frame that carries it

HMB — hydroxymethylbutyrate — is a metabolite of the amino acid leucine, and Solaray's formula delivers 3000 mg from myHMB, a clinically studied form that supports muscle mass maintenance, muscle strength, exercise performance, and endurance. Solaray pitches it as endurance to go the distance, for athletes and anyone who wants to excel in and out of the gym.
What makes this one particularly relevant after 40 is the supporting cast: 13 mcg of vitamin D3 sourced from algae, plus 411 mg of calcium to support healthy teeth and bones. It comes in lemon-lime and vanilla flavors, so it slots into a shake or just a glass of water without ceremony.
If you prefer creatine with a flavor and a twist, Solaray also makes a pineapple Creatine with Shilajit: 5,000 mg of creatine monohydrate for muscle strength, growth, and power, 500 mg of l-leucine, and 150 mg of shilajit, an adaptogen included for additional wellness support.
One reassuring detail for plant-based readers: the vitamin D3 in this formula is sourced from algae rather than the usual animal-derived route, so the endurance-plus-bones combination stays accessible whatever your dietary lines are.
Magnesium: the quiet workhorse for muscle and bone

Magnesium supports healthy muscles, bones, teeth, cellular energy, and nerve function — which is a long way of saying it touches nearly everything this guide cares about. Solaray offers two routes:
- Opti-5 Magnesium delivers 500 mg across five bioavailable forms — Aquamin Magnesium, magnesium bisglycinate, magnesium malate, magnesium citrate, and GivoMag — chosen to support adrenal function plus nerve, muscle, and bone health. It is formulated without magnesium oxide for gentler digestion.
- ActiveMag is the gym-bag option: 210 mg of magnesium malate to support muscles, bones, and nerve function, paired with 99 mg of potassium citrate for electrolyte balance and cardiovascular health support.
For a deeper dive into which form suits which goal, the wider Solaray magnesium family — StressMag, SleepMag, and the rest — covers adjacent goals like relaxation and rest with the same chelated-mineral approach.
Building the stack without overcomplicating it

A sensible strength-support routine after 40 does not need a shelf of tubs. One realistic template:
- Daily foundation: a magnesium formula — Opti-5 for all-around coverage, or ActiveMag if your weeks include regular training.
- Muscle and bone driver: Creatine + MBP as the core scoop, or HMB + Vitamin D3 if endurance and a built-in D3-plus-calcium combo appeal more.
- Consistency mechanism: tie the scoop to an existing habit. Unflavored creatine disappears into anything; the lemon-lime HMB makes a passable midday drink.
Recovery-minded extras can slot in around the core without complicating it. Solaray's USDA organic Tart Cherry concentrate delivers 36 g of tart cherry per serving — a fruit rich in anthocyanins, a nutrient studied for its possible health benefits — with nothing added but the cherries. Its organic Beet Root Juice, with 5.8 g of beet juice per serving and no added sugar, brings nutrient-dense wellness support from the cardiovascular side of the catalog. Neither is mandatory; both are easy, food-first additions for people who prefer drinkable support to another capsule.
Solaray notes its products are produced in its Utah GMP facility, NSF certified and triple-tested — the kind of quality-control detail worth checking on any brand you plan to take daily.

Muscle and bone supplement FAQ
Do I need creatine if I do not lift weights?
Solaray's Creatine + MBP is explicitly aimed at supporting bone and muscle health in aging populations, not just gym performance — though its exercise-recovery support obviously shines brightest when you also move regularly. Supplements support a routine; they do not replace one.
Creatine + MBP or HMB + Vitamin D3 — which one?
They overlap on muscle support but differ in emphasis. Creatine + MBP leans into bone mineral density support via MBP; HMB + D3 leans into muscle mass maintenance and endurance, with vitamin D3 and calcium riding along. Either works as the anchor of a stack — pick the emphasis that matches your goal.
Can I combine these with a longevity routine?
Solaray's unLimit line — NAD+, NMN, fisetin, and friends — targets cellular energy and healthy aging from a different angle, and plenty of shoppers run both. Start with our guide to the Solaray unLimit collection if that side interests you. As always, loop in your healthcare provider before adding new supplements, especially alongside medications.
