Frequently Asked Questions
What is Doctor's Best Phosphatidylserine with SerinAid?
It is a single-ingredient food supplement in capsule form. Each vegetarian capsule provides 100mg of phosphatidylserine, a phospholipid, supplied as the branded ingredient SerinAid. Each bottle contains 120 capsules.
How much phosphatidylserine is in each capsule?
Each capsule provides 100mg of phosphatidylserine. The label direction of one capsule three times daily provides 300mg per day. The 100mg figure is the phosphatidylserine content itself, not the weight of a wider phospholipid complex.
What is SerinAid?
SerinAid is the brand name of the phosphatidylserine ingredient used in this product. It is a registered trademark of Chemi Nutra, the ingredient supplier. Doctor's Best lists it on the label as "PhosphatidylSerine (PS, from SerinAid)".
How long does one bottle last?
At the label direction of 3 capsules daily, 120 capsules last 40 days. Do not take more than 3 capsules per day.
Is there an EU limit on phosphatidylserine in food supplements?
Yes. The EU Union list of novel foods (Commission Implementing Regulation (EU) 2017/2470) authorises phosphatidylserine from soya phospholipids in food supplements at up to 300mg per day. The label direction for this product, 3 capsules daily, provides 300mg. Do not exceed it.
Is phosphatidylserine legal in Ireland, and does it have an authorised health claim?
Phosphatidylserine is sold in Ireland as a food supplement, and food supplements are regulated by the Food Safety Authority of Ireland (FSAI). No health claim for phosphatidylserine is authorised under EU Regulation 1924/2006, so this page makes none. We describe the product by its verified contents only.
Is it suitable for vegetarians and vegans?
The capsule shell is hypromellose, a plant-derived cellulose, not gelatine. The magnesium stearate is from a vegetable source. The manufacturer labels the product vegan and gluten free.
How does it differ from Swanson Phosphatidylserine?
Both provide 100mg of phosphatidylserine per serving. Doctor's Best comes as 120 vegetarian capsules. Swanson comes as 30 gelatine softgels, which are not suitable for vegetarians. The Doctor's Best bottle holds four times as many servings.
