Pros and cons
BiltRx
Pros
- A supplement range and a clinic in one place: online gp, prescriptions and weight loss sit alongside vitamins minerals, collagen and greens on the same account.
- Support covers email, phone and chat, so a phone line and live chat sit next to email and a help centre.
- A money back window of 30 days covers the trial period on supplement orders.
Cons
- BiltRx does not accept insurance, so the $65 monthly plan is paid directly rather than through a policy.
- Consultations run through doctor alone, with no pharmacist or nurse practitioner in that list.
- The shop serves US only, and gluten free is the sole diet listed, so the range is narrow on both geography and diet.
Protein Works
Pros
- Covers a wide list of categories in multivitamins, vitamins minerals and omega 3, from multivitamins to electrolytes.
- Entry point of £8.99 with a per serving cost of £0.15, ranked 15 of 121 brands on price per serving.
- The range suits different diets, with vegan, vegetarian and gluten free options on the multivitamin formula.
Cons
- Delivery covers GB, IE and FR, which is a narrower set of markets than some pharmacy-led rivals.
- The range carries 8 flavours on its whey protein line, but the entry pricing and per serving cost come from the multivitamin product.
- The £8.99 entry price ranks 23 of 157 brands, so the price on the front of the pack sits mid-table.
Who each suits
BiltRx
Who it suits
- US readers who want a supplement order and a clinic consultation to sit on one account rather than two.
- Readers who start with the men's vitality bundle at $36.90 and stay on the subscription rate.
- People who prefer a phone line or live chat, since support covers email, phone and chat.
Who should look elsewhere
- Buyers who want a longer catalogue: DocMorris lists multivitamins, vitamins minerals and omega 3, a wider set of types than the vitamins minerals, collagen and greens here.
- Readers who want greens, collagen and sleep and stress formulas from TestRx or ProSolution Plus, since TestRx lists vitamins minerals and ProSolution Plus lists vitamins minerals.
Protein Works
Who it suits
- Shoppers who want vitamins, probiotics, greens, collagen, sleep and stress, nootropics and electrolytes from one brand.
- People on vegan, vegetarian and gluten-free diets, covered by vegan, vegetarian and gluten free.
- Buyers in the United Kingdom, IE and FR who value a low per serving cost of £0.15.
Who should look elsewhere
- Buyers who need third-party tested products, since DocMorris and other pharmacy brands list independent testing in this category.
- Anyone outside GB, IE and FR, where the GB, IE and FR delivery list does not reach.
- People who want licensed or prescription oversight, as no licence appears against this brand.

Questions about each
BiltRx
What does a BiltRx supplement order cost?+
Supplements start at $36.90, and subscribers pay 10% off the standard rate, so repeat orders cost less than the first ticket price. The clinic plan is billed apart from the shop at $65 a month, and any prescribed medicine sits outside that figure too.
What does the BiltRx monthly plan cover?+
The plan is $65 a month, and the service list covers online general practitioner consultations, prescriptions, weight loss, hair loss, sexual health, skin and menopause care. The supplement range is bought separately in the shop, so a plan does not include a daily vitamin order.
Protein Works
How much does Protein Works cost to start?+
The entry price is £8.99 for the multivitamin product. The same product works out at £0.15 per serving, so a larger pack lowers the cost per serving. The per serving figure ranks 15 of 121 brands in this category.
Is there a discount for ordering repeatedly?+
Yes, subscriptions carry a 15% discount against the entry price of £8.99. The discount applies to repeat orders rather than the first purchase, so it only shows on the ongoing cost. Orders placed on a subscription continue until you change them.
