Fat-soluble Vitamin C, Acerola, Camu Camu - Solvita-C Forte
Reduces fatigue, aids in iron absorption, supports the immune system, and promotes collagen production.
Features a patented complex of liposoluble natural Vitamin C combined with Acerola and Camu-Camu, offering twice the cellular absorption and retention compared to standard Vitamin C.
Contains 60 capsules, each with 500 mg of Vitamin C. One-month supply at 1,000 mg per day (2 capsules daily). Suitable for vegans.

Why take vitamin C on a daily basis?

Unlike most animals, humans do not naturally synthesize vitamin C. Its intake therefore depends exclusively on diet and, in many cases, on appropriate supplementation. However, a vitamin C deficiency can have significant repercussions on the body’s overall balance.
Where does vitamin C act?
Vitamin C contributes to many essential physiological functions. In particular, it helps protect cells against oxidative stress, supports the normal functioning of the immune system, contributes to the reduction of fatigue, improves iron absorption and supports normal psychological function.
It also plays a key role in the normal synthesis of collagen, which is essential for the proper functioning of blood vessels, skin, gums, bones and cartilage, thereby helping maintain tissue structure and vitality.
Vitamin C supports cellular respiration
Cellular respiration relies on a subtle balance of electron exchanges within cells.
Each time the mitochondria, the true power plants of our cells, produce ATP (Adenosine Triphosphate), the essential energy source for the body, by-products are generated.
These by-products, known as free radicals, are unstable molecules that have lost an electron. To regain stability, they seek to capture an electron elsewhere, which can disrupt essential cellular structures.

Vitamin C neutralizes free radicals inside cells

Vitamin C has a unique property: it possesses two electrons that it can donate to effectively neutralize free radicals. Once these electrons have been donated, it is naturally eliminated by the kidneys, without accumulation or toxicity for the body.
There are different forms of vitamin C. Among them, liquid liposomal vitamin C offers an alternative with significantly higher absorption (up to 241% compared to standard vitamin C or liposomal vitamin C in capsule form).
Vitamin C is therefore a fundamental pillar of cellular balance, supporting energy production, antioxidant protection and the overall proper functioning of the body.
Only 10 to 20% of Vitamin C is absorbed!
This is because Vitamin C is unstable and water-soluble, meaning it dissolves in water.
However, our cells are surrounded by phospholipids.
This reality leads to:
- Very poor absorption by the digestive system,
- Difficulty entering cells: Vitamin C circulating in the blood is quickly filtered out by the kidneys.
Solvita-C FORT by Solage — a Vitamin C solution that’s 5 times more effective!
Solvita-C FORT contains natural Vitamin C, liposoluble ascorbic acid, combined synergistically with highly concentrated natural extracts of Acerola and Camu Camu, both rich in natural Vitamin C.
Solage's Vitamin C
This is natural ascorbic acid made liposoluble by a lipid complex, along with bioflavonoids, allowing three key actions:
- Protecting Vitamin C from the digestive system for better absorption
- Being more easily recognized and absorbed by cells, preventing elimination by the kidneys
- Offering superior physiological benefits for neurons, immune support, antioxidant activity, healing (collagen synthesis)...
Additional synergy with Camu Camu and Acerola
Camu Camu and Acerola are small fruits naturally rich in Vitamin C and surrounded by bioflavonoids, which increase absorption and physiological activity.
Camu Camu has a higher antioxidant activity than isolated Vitamin C.
Acerola is retained in the body longer than isolated Vitamin C.
Box of 60 Capsules
Composition per vegetable capsule
- Liposoluble Vitamin C (L-ascorbic acid): 455 mg (569% RDI)
- Acerola (Malpighia glabra L.): 100 mg (31.25% RDI)
standardized fruit extract with 25% Vitamin C
- Camu Camu (Myrciaria dubia): 100 mg (25% RDI)
standardized fruit extract with 20% Vitamin C
RDI: Reference Daily Intake
Take 1 to 2 capsules per day, unless otherwise advised by your healthcare professional.
Solvita-C Fort can be taken in the morning or in the evening, as pure Vitamin C does not interfere with sleep.
Consult your doctor if you are pregnant or breastfeeding.
People with kidney issues should not consume more than 200 mg of Vitamin C daily, due to the risk of hyperoxalemia, among other factors.
When to Use Solvita-C Fort?
- To help the body neutralize free radicals, supporting protection against oxidative stress,
- To support normal immune system function,
- To help reduce fatigue,
- To improve iron absorption,
- To support normal psychological function,
- To aid in normal collagen production, contributing to the normal function of blood vessels, skin, gums, bones, and cartilage.
Several studies have been conducted to examine the absorption and physiological activity of liposoluble Vitamin C PWC compared to ascorbic acid, calcium ascorbate, and the Ester-C complex.
- Faster absorption by the digestive system due to its liposoluble structure (1, 2),
- Vitamin C retention within cells is twice that of ascorbic acid (1),
- Ten times higher growth rate of young neurons, indicating passage into brain cells (3),
- Twice the reduction in inflammation (1),
- Enhanced antioxidant capacity (1, 2, 5),
- Ability to lower LDL (the cholesterol responsible for artery hardening) by more than twice as much (1),
- Twice the improvement in wound healing capacity (3),
- Doubling the protection of white blood cells against toxins (3, 6).

Solage recommends:
- Most of our nutrients come from France or Europe (local is a priority), except when we can't do otherwise (for curcuma, for example). We never choose ingredients from places or countries where quality is not assured and workers are poorly paid.
- Solage products are designed in France and manufactured according to GMP (Good Manufacturing Practice) standards from the pharmaceutical industry and the HACCP (Hazard Analysis Critical Control Point) method, developed by NASA.
Both methods implement procedures, documents and controls to guarantee perfect traceability and the absence of biological or chemical contamination.
- Solage is a French company, and its products are registered with the relevant authorities.
Solage products are safe, with no bad surprises.
To answer this question, we distinguish between three types of product, depending on their nature and intended purpose:
1/ Ideally taken as a continuous treatment: those which compensate for a nutritional or age-related deficiency, and which serve to restore the body's functions without altering its normal metabolism.
- Common nutritional deficiencies: marine omega-3, vitamin C, magnesium, vitamin D between October and May
- Age-related or pathological deficiencies: Ubiquinol, Glutathione, Iron, Collagen (type I and II)
- To help the body deal with underlying problems: Saffron, Ashwagandha, Men's and women's urinary comfort, cholesterol
2/ To be taken in a cure, but where a break is not necessarily necessary if you or your healthcare professional find it useful:
Detox: Milk thistle, Glutathione
Digestion: Probiotics
3/ Products where a break is useful:
- Curcumin: at least a break of a few days between each box, as it modifies metabolic pathways in the body
- Echinacea (immunity): a break of a few days between each box so as not to over-stimulate the immune system
- Melatonin: avoid taking it every day over the long term, so as not to habituate the body.
In all cases, it's important to remember that the products we offer are genuinely active, that it's important to respect dosage and that they are not a substitute for a varied, balanced diet and a healthy lifestyle.
This will of course depend on the product and your physiological state.
It's worth remembering that physiology is a long-term process, and that it generally takes two to three months, sometimes longer, to achieve a profound change.
However, the feeling is generally quicker, between 15 days and two months.It is then necessary to continue to try to fix these initial results in greater depth.
However, this will be much quicker with subsequent products:
- Melatonin and sublingual GABA, which have a very rapid onset of action (between two minutes and 30 minutes)
- Probiotics (48 hours to two weeks))
Please refer to the “Scientific studies” section of this product page, where you'll find most studies on bioavailability and medium-term effects.
