Pros and cons
BioProphyl
Pros
- Price per serving of €0.21 ranks 18 of 121, well ahead of its 64 of 157 on entry price
- multivitamins, vitamins minerals and omega 3 covers several daily categories under one brand, including multivitamins, probiotics and greens
- Third-party tested, with organic certification in organic
Cons
- Delivery is limited to the markets listed in Belgium, DE and NL, so readers outside that area are not served
- Certification runs to organic only in organic, a narrower mark than the GMP labelling many rival brands carry
- Range is thinner than a full retailer: multivitamins, vitamins minerals and omega 3 leaves out collagen, nootropics and electrolytes
Gruns
Pros
- Covers greens and vitamins minerals in one brand, so a daily routine does not need splitting across makers.
- Third-party testing is stated, and the products carry nsf and gmp certification.
- Subscription orders are reduced by 55%, which is the cheapest way to hold the daily price at $1.07 a serving.
Cons
- Gruns sells in US only, so buyers elsewhere cannot order from the brand directly.
- The subscription discount of 55% is tied to repeat orders, and the entry price of $29.99 is the figure at the top of the range.
- Product types cover greens and vitamins minerals, and a wider range sits at DocMorris, which lists multivitamins, vitamins minerals and omega 3.
Who each suits
BioProphyl
Who it suits
- Readers building a daily routine across several supplement categories rather than a single targeted formula
- Shoppers who want vegan, vegetarian or gluten-free options, covered by vegan, vegetarian and gluten free
- Anyone whose main measure is running cost per serving rather than the upfront bottle price
Who should look elsewhere
- Readers who want collagen, nootropics or electrolytes under one roof, since DocMorris carries those alongside multivitamins, vitamins minerals and omega 3
- Anyone living outside BE, DE and NL, where delivery is not offered
- Shoppers who need live chat, as email, phone and help centre lists email, phone and a help centre
Gruns
Who it suits
- US adults who want greens and vitamins covered by a single daily subscription rather than separate products.
- Vegan shoppers and anyone avoiding gluten, as the range is vegan and gluten free.
- Readers who care about independent testing and named certification, since the products are third-party tested and carry nsf and gmp.
Who should look elsewhere
- Buyers outside the US, since Gruns operates in the United States only.
- Shoppers who want a single specific product such as omega-3, probiotics, collagen or electrolytes, which sit with DocMorris at multivitamins, vitamins minerals and omega 3.
- People who would rather test a men's health brand such as ProSolution Plus or TestRX, where vitamins minerals and vitamins minerals are the only listed types.

Questions about each
BioProphyl
Does BioProphyl charge a subscription fee?+
BioProphyl sells one-off bottles rather than a subscription, so there is no renewal price to weigh against the entry price. Buying again means paying €24.72 for the same pack, and nothing about the order changes over time. The per-serving figure of €0.21 is the number that decides whether a repeat order is worth making.
How does the per-serving price compare with other brands?+
BioProphyl's per-serving cost of €0.21 sits below the site median of €1.17. The brand ranks 18 of 121 on that measure, a much stronger placing than the 64 of 157 it holds on entry price.
Gruns
How much does Gruns cost at the point of buying?+
The entry price is $29.99 across the collection. That is the figure a reader meets first when ordering. Once a routine is running, the cost that matters is the serving price of $1.07. Keep the two apart, since they are different numbers for different stages of buying.
What does a Gruns subscription cost over time?+
Repeat orders carry a discount of 55%, and that is the route that holds the serving price down. A one-off order pays the entry price of $29.99 instead, so the ongoing figure only applies on a schedule. A 30 day money back window gives a first order time to be judged.
