Easy to mix up, pleasant flavoured supplement for very elderly mother to improve nutrition
I’ve been buying this for some time
Solubility is good. Not as tasty as the normal Sustagen Plus.
I’ve been having Sustagen Optimum from the time my now 7 month old baby was born. It helps with meeting my nutritional needs while breastfeeding and the low lactose formulation is gentle on my lactose intolerant tummy. On top of that, it tastes great too!
Actually tastes better than most of these types of drinks! Just add pureed fruit
The Dietitian suggested my husband use this product to help him put on weight. Suggested making smoothies as well as adding to cereal. He has put on 3 kg so very happy with the results
This is my go to good when my entral feeds formula is not available. Being lactose intolerant Its very easy on my stomach. although its not a full diet replacement, itdefinitely gets me through for a few weeks.
