The form of each ingredient matters.
We consider the form of every ingredient. Zinc bisglycinate is one example: research comparing it with zinc gluconate helped inform our choice. Explore the study below.
A pharmacist-formulated supplement with a reason behind every ingredient. From the forms we choose to the amounts we include, discover the thinking behind your two daily capsules. What we leave out matters too.

Zinc contributes to the maintenance of normal hair, skin and nails.
Vitamin B12 contributes to the reduction of tiredness and fatigue.
Vitamin D contributes to the maintenance of normal bones and normal muscle function.
Our founder’s pharmacy background shapes the formula: considering the evidence for each nutrient, its amount and its suitability for inclusion. Here’s what that means in practice.

We consider the form of every ingredient. Zinc bisglycinate is one example: research comparing it with zinc gluconate helped inform our choice. Explore the study below.
Too much of some nutrients can be harmful. We assess each nutrient separately, weighing potential benefits against potential risks to choose an amount with a reason behind it.
Every nutrient gets a risk-to-benefit assessment. For manganese, its availability in food, limited evidence of added benefit and uncertainty around long-term supplementation led us to leave it out.
Explore the reasoning behind these choices.
A randomised crossover trial in 12 healthy women found 43.4% higher zinc bioavailability with zinc bisglycinate than zinc gluconate following a single 15 mg dose. Bioavailability describes how much reaches the bloodstream.
This comparison of zinc forms helped inform our choice of zinc bisglycinate.
Read the studyAn upper intake limit is not a recommended daily amount. We consider the nutrient, its form, intake from food and supplements, and evidence about longer-term use when choosing how much to include.
Selenium is one example of why we look beyond whether a dose appears well tolerated. Our Science page explains the research and its limitations.
Explore the selenium exampleTwo capsules provide 14 mg of zinc (140% of the Nutrient Reference Value, or NRV). We considered both dietary intake and factors that can affect zinc absorption when choosing this amount.
See the full nutrient amountsAn essential nutrient does not automatically need to be added to an everyday supplement. We weigh the potential benefits against the potential risks, considering dietary sources, evidence of additional benefit and uncertainties about supplementation.
Explore our manganese and calcium examplesWe weigh the evidence available, consider its strengths and limitations, and acknowledge what remains unknown. Thoughtfulness and humility guide those decisions.
Our Science page explains how this approach shapes our choices, including the amount of selenium we include.
